Immunization of Wistar female rats with 255-Gy-irradiated Toxoplasma gondii: Tissue parasitic load and lactogenic quantification.

Toxoplasma gondii is one of the most significant parasite, due its importance in veterinary medicine and in public health, considered a food-borne pathogens, there is no available drug treatments to eliminate it from animal tissue, this reinforce the search for a vaccine against this parasite. This study was aimed to evaluate the dynamic of the distribution of T. gondii in tissues of female Wistar rats and their milk, after the immunization by oral rote with irradiated tachyzoites.

Coinfection by Toxoplasma gondii and Leishmania spp. in domestic cats (Felis catus) in State of Mato Grosso do Sul.

Introduction: Leishmaniasis and toxoplasmosis are important to public health.

Methods: Antibodies for Toxoplasma gondii and Leishmania spp. were evaluated in cats from Campo Grande, State of Mato Grosso do Sul, Brazil, a region endemic for canine visceral leishmaniasis.

Immunization of Wistar female rats with 255-Gy-irradiated Toxoplasma gondii: preventing parasite load and maternofoetal transmission.

Toxoplasmosis, caused by an obligate intracellular protozoan parasite, Toxoplasma gondii, is an worldwide parasitic disease, with significant importance for animal production and considerable impact to the public health. This study was aimed to evaluate the dynamic of the distribution of T.gondii in tissues of female Wistar rats and their puppies tissues, after the immunization by oral rote with irradiated tachyzoites.

Prevalence of Toxoplasma gondii and Leishmania spp. infection in cats from Brazil.

A total of 386 feline blood samples from Brazil were collected and analyzed by the indirect immunofluorescence antibody test (IFAT) for the presence of Toxoplasma gondii and Leishmania spp. antibodies. Specific antitoxoplasma IgG were found in 63 of 386 (16.

Serologic survey for Leptospira spp. in captive neotropical felids in Foz do Iguaçu, Paraná, Brazil.

Leptospirosis is a bacterial zoonosis of worldwide distribution and is endemic in tropical countries, where rodents and other wild mammals are abundant and may act as reservoirs. Leptospirosis has become a concern in captive wild animals, due mostly to their exposure to contaminated urine or environment. Although domestic cats (Felis catus) have been reported refractory to leptospirosis, serology and disease in captive wild felids is still unclear.

Surveillance of canine visceral leishmaniasis in a disease-free area.

Leishmaniasis is an important re-emergent parasitosis worldwide, particularly in tropical countries. There are no reports of autochthonous disease in the State of Paraná, southern Brazil. No surveillance has been carried out in the most populated areas such as the city of Curitiba and its surroundings.
