Meat of any animal should be cooked to 67C (152.6F) before consumption, and tasting meat while cooking or while seasoning should be avoided. A total of 362 blood samples were obtained from stray and pet cats. Cornell University College of Veterinary Medicine, Cornell Ruffian Equine Specialists, on Long Island, Cornell Veterinary Experts Address Feline Nutrition, CDCs website for its most recent recommendationsregarding the risk of toxoplasmosis to humans, Do not eat unwashed fruits and vegetables, Do not drink environmental water that has n ot been filtered/boiled, Do not feed unpasteurized milk or raw meat to cats, Wash hands and food preparation surfaces with warm soapy water after handling raw meat, Wear gloves when gardening and wash hands afterward, Keep sandboxes covered and don't allow cats to use them as litter boxes, Do not allow cats to hunt or roam unsupervised, Remove feces from the litter box daily and wash it frequently with boiling water, Do not allow pregnant women or immunosuppressed people to clean the litter box, Control populations of rodents andother intermediate hosts. Graham Head, 66, who kidnapped and tried to rape two women, was caught after one victim remembered three digits of his car registration. Pregnant women should avoid contact with cat litter, soil, and raw meat. Routine hematologic and biochemical parameters may be abnormal in cats and dogs with acute systemic toxoplasmosis. The tachyzoite is the form that can invade cells in the body where it then multiplies rapidly and can destroy cells. Loss of contrast in the right abdominal quadrant can indicate pancreatitis. Cats of any age may die or develop severe disease following parenteral inoculation with tachyzoites, bradyzoites, or oocysts, and large doses of corticosteroids can aggravate clinical toxoplasmosis (1). o [ canine influenza] Owning a cat does not mean you will beinfected with Toxoplasma. The absence of anyT. gondii antibodies in a healthy cat suggests that the catis susceptible to infection and would shed oocysts for upto two weeks following infection. It has been found worldwide. Differential diagnosis might be influenced by the geographical location where the clinical cases occur; for example, S. neurona causing encephalitis and Sarcocystis canis causing hepatitis have been confined to the Americas (78). Gerhold R, Newman SJ, Grunenwald CM, Crews A, Hodshon A, Su C. Acute onset of encephalomyelitis with atypical lesions associated with dual infection of. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Thoracic radiographic findings, especially in cats with acute disease, consist of a diffuse interstitial to alveolar pattern with a mottled lobar distribution. IgM antibodies appear sooner after infection than IgG antibodies; generally, however, IgM antibodies do not persist past 3 months after infection. Toxoplasma gondii is an obligate intracellular coccidian parasite that can infect virtually all species of warm-blooded animals, including people. Hence, this review aims to provide a comprehensive analysis of some scarcely discussed aspects of toxoplasmosis, such as ocular and cutaneous manifestations, congenital infections, influence of T. gondii genotype on clinical toxoplasmosis, and recent findings regarding differential diagnosis. Cutaneous toxoplasmosis in an immunosuppressed dog. It is found worldwide. Serum creatine kinase activity is also increased in cases of muscle necrosis. Anterior or posterior uveitis involving one or both eyes is common. Most reports are in dogs that are immunosuppressed and not vaccinated against the distemper virus. Enter search terms to find related veterinary topics, multimedia and more. da Silva RC, Caffaro K, Paula CL, Risseti RM, Langoni H, Megid J, et al. The material collected from the skin lesions was negative for fungal and bacterial cultures, and tachyzoites were found on the Giemsa-stained smears. If your vet finds your cat had toxoplasmosis, the disease can be treated with antibiotics. The bile ducts are hyperplastic and plugged with desquamated bile duct epithelium and exudate. Dubey JP, Calero-Bernal R, Rosenthal BM, Speer CA, Fayer R. Hoon-Hanks LL, Regan D, Dubey JP, Carol Porter M, Duncan CG. This form then spreads from the intestine toother parts of the cat. The good news is it's usually no big deal for healthy adult cats. Toxoplasmosis of Animals and Humans. 43-day-old mixed-breed puppy, showing convulsions, blindness, and spontaneous death. The trusted provider of veterinary information since 1955, Reviewed/Revised Aug 2021 | Modified Oct 2022. Toxoplasmosis, erhlichiosis and distemper virus co-infection in a dog with an exuberant neuropathological clinical picture. Cats infected during pregnancy can develop placentitis, and congenitally infected kittens, severe toxoplasmosis, including ophthalmitis (54, 5961). Recent articles reporting on congenital infection in cats are scarce. CRC Press; 2010. Yes, bioassay in mice and culture in Vero cell line. OIE Terrestrial Manual 2017, Chapter 2.9.9: Toxoplasmosis. Finally, immunocompromised adult animals (eg, cats infected with feline immunodeficiency virus) are extremely susceptible to developing acute generalized toxoplasmosis, mainly expressed as neurologic and respiratory disorders. Dubey JP, Black SS, Verma SK, Calero-Bernal R, Morris E, Hanson MA, et al.. Prandini da Costa Reis R, Crisman R, Roser M, Malik R, lapeta J. Neonatal neosporosis in a 2-week-old Bernese mountain dog infected with multiple, Pulmonary sarcocystosis in a puppy with canine distemper in Costa Rica. Sulfadiazine (1525 mg/kg, PO, every 12 hours for 4 weeks) and pyrimethamine (0.44 mg/kg, PO, every 12 hours for 4 weeks) act synergistically and are widely administered for treatment of toxoplasmosis. IFAT, Congenital infection (no clinical signs in mother nor pups), 18-month-old female cattle dog that gave birth to 6 seronegative pups. Cats generally develop immunity to T gondii after the initial infection, and they shed oocysts only once in their lifetime; however, immunocompromised animals can re-shed oocysts. As mentioned before, clinical cases are frequently associated with immunosuppressive treatments (20, 79, 80). It isunlikely that you would be exposed to the parasite bytouching an infected cat, because they usually do notcarry the parasite on their fur. Little is known of transplacental toxoplasmosis in dogs, although its prevalence is thought to be less common than that in sheep and goats. Clinical signs of systemic illness usually begin to resolve within 24 to 48 hours after institution of therapy. All rights reserved. Infection with T gondii may occur after ingestion of undercooked meat or accidental ingestion of oocysts from cat feces thorough contaminated water or vegetables. Thus, whether disease depends on immunological status, infection dose, co-infection rates, and geographical location (understood as genetic variant distribution), rather than on specific genotype involvement, is still under debate. Accessibility Tissue cysts usually occur in neurons; however, they also occur in other tissues, such as muscles. On the top of that, there is a wide genetic diversity within the parasites isolated from asymptomatic dogs (73, 74) and cats (72, 75), corresponding to a complex epidemiology shown in different geographical areas [(76), http://toxodb.org/toxo/]. Before Disease information and advice Toxoplasmosis Toxoplasmosis On this page Key messages Toxoplasma gondii - a protozoan - occurs worldwide in mammals and birds. This is a microscopic single-cell organism related to coccidia. Malmasi A, Mosallanejad B, Mohebali M, Sharifian Fard M, Taheri M. Prevention of shedding and re-shedding of. In addition, it was reported that clinically ill cats can shed oocysts (28), suggesting that special precautions must be taken during clinical care. FIV, Feline immunodeficiency virus; FeLV, Feline leukemia virus; MAT, modified agglutination test; IHQ, immunohistochemistry; PCR, polymerase chain reaction; RFLP, restriction fragment length polymorphism. Other review papers have focused on toxoplasmosis diagnosis and treatment. Antemortem diagnosis may be accomplished by indirect hemagglutination assay, indirect fluorescent antibody assay, latex agglutination test, or ELISA testing. T gondii may be transmitted vertically and produce fetal lesions and abortions. Serologic evidence of recent or active infection consisting of high IgM titers, or fourfold or greater, increasing or decreasing, IgG or other antibody titers (after treatment and/or recovery), 2. Springer; 2018:149-168. 2 , 6 , 13 , 97 , 98 Care should be taken to control transport hosts such as cockroaches that have been shown to . Oops! Nevertheless, pyrimethamine and sulfonamides inhibit folic folinic acid metabolism in T. gondii to a greater extent than in the mammalian cell, so that supplementation with folic acid does not completely reverse therapeutic efficacy when used in combination with pyrimethamine and sulfonamides. Myelitis due to reactivated spinal toxoplasmosis in a cat. (86), N. caninum (85), and lungworms (87); hepatitis in dogs by Sarcocystis spp. Parasites Home Toxoplasmosis Prevention & Control People who are healthy should follow the guidelines below to reduce risk of toxoplasmosis. Yes, in mice, from brain (no ID provided), 9 isolates (SAG2 marker): 4 of type I, and 5 of type III (ToxoDB incomplete allele profile), 34 out of 111 dogs euthanized because of the severity of neurological signs. Weingart C, Gruber AD, Brunnberg M, Kohn B. Spycher A, Geigy C, Howard J, Posthaus H, Gendron K, Gottstein B, et al.. Jokelainen P, Simola O, Rantanen E, Nreaho A, Lohi H, Sukura A. Many of these children, however, are likely to developsigns of infection later in life, including loss of vision andhearing, mental retardation, and, in severe cases, death. Cases of intracranial granuloma (34, 35) and panencephalitis (36) have been also addressed. Oliveira TS, Turchetti AP, Barbosa FBS, Bicalho ALF, Alencar CAD, Paixo TA, et al. Mor G, Venturini MC, Pardini LL, Unzaga JM. Because of its good intestinal absorption, oral and parenteral dosages are similar. Clinical signs usually appear when cats become immunosuppressed - in these situations, cystic stages can be reactivated. The corresponding clinical signs include fever, diarrhea, cough, dyspnea, icterus, seizures, and death. Cats with concurrent FIV infections do not respond as well as FIV-naive cats to therapy. The vastmajority of women infected during pregnancy haveno symptoms themselves, and the majority of infectedinfants will show no symptoms of toxoplasmosis at birth. In adults, unspecific clinical signs can be observed (19, 20). Infection through milk ingestion in cats is supported by results, such as the detection of T. gondii by bioassay and PCR in milk of nursing queens after experimental infection (58). Treatment usually involves a course of an antibioticcalled clindamycin, either alone or in combination withcorticosteroids if there is significant inflammation of theeyes or central nervous system. Tachyzoites may also be transmitted to the fetus, causing necrosis in multiple organs. Steps that can be taken to minimize Toxoplasma infection in order of importance: Supporting Cat Health with Information and Health Studies. Toxoplasmosis is caused by the globally distributed intracellular protozoan parasite Toxoplasma gondii (phylum Apicomplexa, family Sarcocystidae). The re-shedding of oocysts by cats remains an important aspect in the epidemiology of T. gondii. Animal was immunosuppressed. Wild and domestic felines (members read more . Serum was tested for N. caninum, T. gondii, Leishmania infantum chagasi, and Leishmania amazonensis IgG antibodies, and only T. gondii antibodies were detected (IFAT titer = 65,536). It can lead to flu-like symptoms. Webb JA, Keller SL, Southorn EP, Armstrong J, Allen DG, Peregrine AS, et al.. Cutaneous manifestations of disseminated toxoplasmosis in an immunosuppressed dog, Neonatal toxoplasmosis in littermate cats, Histologically confirmed clinical toxoplasmosis in cats: 100 cases (1952-1990). T. gondii schizonts (not tachyzoites) were seen in the biliary epithelium in both naturally occurring and experimentally induced disease. Queens of the Stone Age will bring Phantogram, Viagra Boys, the Armed, and Savages' Jehnny Beth along for the ride on their fall North American tour, which will begin Aug. 3 in Sterling Heights . Gloves should be worn while gardening. Companion Animal Hospital in Ithaca, NY for cats, dogs, exotics, and wildlife, Equine and Nemo Farm Animal Hospitals in Ithaca, NY for horses and farm animals, Cornell Ruffian Equine Specialists, on Long Island for every horse, Ambulatory and Production Medicine for service on farms within 30 miles of Ithaca, NY, Animal Health Diagnostic Center New York State Veterinary Diagnostic Laboratory, Cornell University College of Veterinary Medicine Ithaca, New York 14853-6401, Toxoplasmosis is adisease causedby the single-celledparasiteToxoplasmagondii (T.gondii). Oocysts are excreted in feces, whereas tachyzoites and bradyzoites are found in tissues. Isolation and biological and molecular characterization of. Ocular toxoplasmosis has been observed in cats without poly-systemic clinical signs of disease, and anterior or posterior uveitis, iritis, iridocyclitis, or chorioretinitis. These cats are no longer sourcesof infection for other hosts. Dubey JP. T gondii is morphologically similar to other protozoal parasites and must be differentiated from Sarcocystis species and Neospora caninum, which may also be involved in abortions and infection of neurologic tissues. 1Saluvet Group, Department of Animal Health, Complutense University of Madrid, Madrid, Spain, 2Program of Master's in Animal Medicine and Welfare, Faculty of Veterinary Medicine, University of Santo Amaro, So Paulo, Brazil, 3Faculty of Veterinary Medicine, University of So Paulo, So Paulo, Brazil. Because adult immunocompetent animals control tachyzoite transmission efficiently, toxoplasmosis is usually a subclinical illness. Toxoplasmosis is an infectious disease that is caused by a parasite. More than 60 million people in theU.S. are thought to be infected. Acute infection is usually asymptomatic, and once acquired, parasites remain in human tissues lifelong. The aim of this study was to determ Dorny P, Speybroeck N, Verstraete S, Baeke M, De Becker A, Berkvens D, et al.. Clinicopathologic diagnosis of cutaneous toxoplasmosis in an angora cat. They are rarely found in blood, CSF, fine-needle aspirates, and transtracheal or bronchoalveolar washings7 but are more common in the peritoneal and thoracic fluids of animals' developing thoracic effusions or ascites. 111 dogs admitted in veterinary services with neurological symptoms: ataxia, seizures, behavioral changes, paralysis and paraplegia of members, and tremors. A few cases of feline clinical toxoplasmosis combined with feline immunodeficiency virus (FIV) (63) and feline leukemia virus (FeLV) (40) have been described. Cats should preferably be fed commercially prepared,cooked foods (appropriate heating inactivates any T.gondii cysts that may be present) and should not beallowed to eat uncooked meat or intermediate hosts,such as rodents. Bradyzoites are released from tissue cysts by digestion in the stomach and small intestine, invading intestinal epithelium, and undergoing asexual and sexual replication, culminating in the release of oocysts (~10 mcm in diameter) in the feces. Other animals, including humans, are intermediate hostsof T. gondii and can become infected by eating cystsor oocysts. Fatal extraintestinal toxoplasmosis in a young male cat with enlarged mesenteric lymph nodes. Clinical toxoplasmosis is more frequent in cats than in dogs, which commonly suffer from neosporosis by Neospora caninum, and among them, non-vaccinated animals are more susceptible. Magaa A, Snchez F, Villa K, Rivera L, Morales E. Systemic neosporosis in a dog treated for immune-mediated thrombocytopenia and hemolytic anemia. Tachyzoites infect tissues throughout the body and replicate intracellularly until the cells burst, causing tissue necrosis. Cats often show proteinuria and bilirubinuria. Multiple serologic tests for the detection of antibodies have been used in the diagnosis of toxoplasmosis. Al-Qassab S, Reichel MP, Su C, Jenkins D, Hall C, Windsor PA, et al.. da Silva AV, Pezerico SB, de Lima VY, d'Arc Moretti L, Pinheiro JP, Tanaka EM, et al.. Moretti Ld, Da Silva AV, Ribeiro MG, Paes AC, Langoni H. Langoni H, Matteucci G, Medici B, Camossi LG, Richini-Pereira VB, Silva RC. Occasionally fever and swollen glands can occur. Toxoplasma. See Figure 1 for an illustration of the life cycle of T. gondii. You might have heard before that if you're pregnant or plan to become pregnant, you should re-home your cat because of a disease called toxoplasmosis. Tissue cysts in the host remain viable for many years, and possibly for the life of the host; thus serving as an important source of infection for scavengers, both carnivores, and omnivores. Also histologic examination of tissue sections may reveal the presence of tachyzoites or bradyzoites, which could be specifically marked by immunohistochemical staining. Two month later, the dog was diagnosed with severe erythroid and myeloid aplasia, megakaryocytic aplasia, myelonecrosis with lymphoplasmocytic infiltration, and grade II fibrosis. It is one of the most common parasitic diseases andinfects nearly all warm-blooded animals, includingpets and humans. Experimental toxoplasmosis in pregnant bitches. In some cases, T. gondii tachyzoitesmay be excreted in the milk of infected cows and goats. Feeding your cat canned food or dry food is the best option to cut down on the possibility of her carrying this parasite. Clostridium difficile overgrowth has not been documented in dogs and cats as it has been in people treated with clindamycin. All homoeothermic animal species may be infected. As an instance of cutaneous toxoplasmosis was described in an immunosuppressed dog. Toltrazuril, ponazuril, and diclazuril may be administered to treat acute toxoplasmosis, as well as to reduce the shedding of oocysts by cats. Neurologic and ocular lesions can arise in immunocompromised and elderly cats. Domestic cats and other Felidae are the definitive hosts. The main host in Australia is the domestic cat, which become infected mainly through eating small infected mammals, including rodents and birds. Oocysts passed in the feces of cats are notimmediately infectious to other animals. In people who are either undergoingimmunosuppressive therapy or have animmunosuppressive disease such as acquiredimmunodeficiency syndrome (AIDS), toxoplasmosis maycause enlargement of the lymph nodes, eye and centralnervous system disturbances, respiratory disease, andheart disease. While T. gondii seldomly causessignificant symptoms in healthy adults either (see belowfor exceptions), the Centers for Disease Control andPrevention (CDC) has recently identified toxoplasmosis asone of five neglected parasitic infections of. T gondii initiates enteroepithelial replication in unexposed felids after ingestion of uncooked tissues containing cysts. Yes, in mice, from skin aspirate. Human exposure to toxoplasmosis is common wherever cats are found. Hosts can become infected horizontally by ingesting tissues containing cysts, consuming water or food contaminated with oocysts, or by transfusion or transplantation with parasitized organs. Andrews C, Gerdin J, Patterson J, Buckles EL, Fitzgerald SD. We can ensure we dont have gardens or soft sand in areas the joeys inhabit and try to keep cats out, however toxoplasmosis cysts can be brought in on contaminated feed, or washed into pens by runoff from rain or sprinklers. Infected cats can transmit the disease to humans and other animals. Freezing or x-ray irradiation can kill tissue cysts without affecting meat quality. However, because intraocular inflammation commonly leads to lens luxation and glaucoma, cats with anterior segment inflammation should be treated with topical, oral, or injectable glucocorticoids. Preventing toxoplasmosis in dogs and cats involves measures intended to reduce the incidence of feline infections and subsequent shedding of oocysts into the environment. Toxoplasma individuals in tissue cysts are also killed by exposure to 0.5 kilorad of gamma irradiation. There is no vaccine to protect against toxoplasmosis inanimals or humans. Yes, bioassay in mice with oocysts shed in cat feces. Dubey JP, Pimenta AL, Abboud LC, Ravasani RR, Mense M. Dermatitis in a dog associated with an unidentified. Feline toxoplasmosis in Finland: cross-sectional epidemiological study and case series study, Fatal disseminated toxoplasmosis in an immunocompetent cat. Patitucci AN, Alley MR, Jones BR, Charleston WAG. A wide range of histologic lesions included: proliferative interstitial pneumonia, necrotizing hepatitis, myocarditis, skeletal and glossal myositis, non-suppurative encephalitis affecting the cerebrum, brain stem, and spinal cord, uveitis, necrotizing adrenal adenitis, and interstitial nephritis. TgDgBr20 characterized as mouse virulent. A high proportion of animals and humans are infected without clinical signs. For cat lovers. Seizures, cranial nerve deficits, tremors, ataxia, and paresis or paralysis may be seen. Received 2018 Oct 29; Accepted 2019 Feb 7. Primary or reactive neurological disease is frequent in cats; infection of the encephalon (30), spinal cord, and nerves has been identified (3133). Bresciani KD, Costa AJ, Toniollo GH, Luvizzoto MC, Kanamura CT, Moraes FR, et al.. Lesions of neonatally induced toxoplasmosis in cats. Seroconversion was observed in all females seven days after AI, and reabsorption occurred in two of the dogs. A seropositive cat is probably not currently shedding oocysts and is less likely to shed oocysts if re-exposed or immunosuppressed. There are three stages in the protozoan's life cycle that explain its biological success. A 5-year-old male mixed breed, presented intense dyspnea and died 3 days later. The three major modes of transmission are congenital infection, ingestion of infected tissues, and ingestion of oocyst-contaminated food or water. Between one-thirdand one-half of infants born to mothers who acquiredToxoplasma during pregnancy are infected. (TgCatUs9). This concept is still under study. However, in susceptible species, as well as in young and immunocompromised animals (particularly puppies, kittens, and piglets), tachyzoites are transmitted systemically and cause interstitial pneumonia, myocarditis, hepatic necrosis, meningoencephalomyelitis, chorioretinitis, lymphadenopathy, and myositis. Little is known about transplacental toxoplasmosis in dogs, although its occurrence is thought to be less common than in other species (1). The level of exposure to Toxoplasma gondii is influenced by culture and eating habits. Cat Health Here's What You Should Know About Toxoplasmosis In Cats Ewww By Sam Howell Published on 12/17/2021 at 4:41 PM You might be thinking, "What the heck is toxoplasmosis?" It's actually a parasitic infection your cat can get. West nile virus encephalitis and myocarditis in wolf and dog. Bolckmans A, Gielen I, Van Soens I, Bhatti S, Poncelet L, Chiers K, et al. fever swollen glands ( lymph nodes) body aches headache tiredness Babies with congenital toxoplasmosis often don't have any symptoms at birth. Toxoplasmosis is a zoonotic infection (acquired from animals) caused by the protozoan parasite Toxoplasma gondii ( T. gondii ). Tissue cysts are formed in the CNS, muscles, and visceral organs and probably persist for the life of the host. Additionally, some of the T. gondii released fromcysts from the infected meat will penetrate moredeeply into the wall of the cats intestineand multiply as yet another form, called a tachyzoite. Reduce Risk from Food To prevent risk of toxoplasmosis and other infections from food: Cook food to safe temperatures. Feline immunodeficiency virus predisposes cats to acute generalized toxoplasmosis. Clinical signs reflect inflammation of the liver, lungs, and CNS. Just click, World Small Animal Veterinary Association World Congress Proceedings, 2005, Animal Parasitic Diseases Laboratory, Animal and Natural Resources Institute, Agricultural Research Service, United States Department of Agricultural, b35e26d2-0ced-49de-a666-db5a0f138a0e.1686225014, VINcyclopedia of Diseases (Formerly Associate), Books & VINcyclopedia of Diseases (Formerly Associate), Intravitreal Uveal Ablation with Gentamicin, Antagonistic Effect of Atipamezole in Cats, Electrocardiography in Anesthetized Dogs, IgG and IgM and Complement Bound to Erythrocytes, Inhalatory Anesthesia for Pericardiectomy, Simultaneous Biliary and Mammary Carcinomas, Surgical Treatment of Chronic Otitis Externa, Companion Animal Welfare: European/Italian Law, Neostigmine in Massive Ivermectin Toxicity. 8600 Rockville Pike Two and a half months later, the dog presented dermal lesions, initially small, hard, and slightly erythematous that rapidly evolved to large hard nodules that ulcerated with drainage of purulent material. Abdominal radiographic findings may consist of masses in the intestines or mesenteric lymph nodes or homogeneous increased density as a result of effusion. TgDogBr (btu1-3). In cats clinical toxoplasmosis is most severe in transplacentally infected kittens. A high proportion of T. gondii clinical infections are triggered by immunosuppressive chemotherapy (5). Falzone C, Baroni M, De Lorenzi D, Mandara MT. If the cell ruptures, they infect new cells. Most adults with toxoplasmosis are asymptomatic. Some cases of anterior segment inflammation thought to be from toxoplasmosis have resolved with the administration of clindamycin alone. Asymptomatic infection in humans is common. In contrast, IgG antibodies appear by the fourth week after infection and may remain increased for years during subclinical infection. Wild and domestic felines (members of the cat family) are the only definitive hosts of the parasite. Bethesda, MD 20894, Web Policies Neurologic signs depend on the site of lesion in the cerebrum, cerebellum, or spinal cord. For dogs and cats, clindamycin is the treatment of choice, administered PO every 12 hours for 3-4 weeks at 10-12.5 mg/kg in dogs and 25-50 mg/kg in cats. In dogs, T. gondii was isolated from pups from a seropositive bitch in Australia; however, no clinical signs were seen in any of the animals (45) (Table 1). 4-year-old female mixed breed, showing hyporexia, diarrhea with mucous, and tachypnea. CT65/16). Clindamycin dosages for treating toxoplasmosis are greater than those for treating anaerobic infections for which the drug is marketed. RC-B is funded by the postdoctoral grants of the Complutense University of Madrid (ref. Neurologic deficits improve, but signs may not totally resolve because of permanent damage caused by CNS inflammation. Baker's yeast, which contains folic acid, is inexpensive and as effective as folinic acid. The disease may be rapidly fatal in cats with severe respiratory or neurological signs (18). Experimental infection of queens in the middle third of pregnancy, using two different Brazilian isolates (BrI, BrIII), showed almost no difference in abortion and premature stillbirth rates (56). T. gondii DNA was detected in fresh semen from five out of eleven seropositive naturally infected healthy dogs in Brazil, and in vitro isolation of the parasite was achieved (50).
