Toxoplasma Gondii Infection

Toxoplasmosis, a disease caused by the intracellular coccidian Toxoplasma gondii that infects most warm-blooded vertebrates, is widely distributed and fatal for primates, which are peculiarly susceptible for unknown reason(s). Owing to the increasing number of Neotropical mammal deaths where in T. gondii were detected in analyzed tissues, the present immunohistochemical study analyzed the distribution patterns of immunostainings related to this parasite on primates necropsied at the Laboratório de Patologia Animal of Universidade de Passo Fundo (UPF), between the years of 2000 and 2014. Furthermore, a serological survey for the disease was conducted for 21 primates from the UPF Zoo, Rio Grande do Sul, Brazil, belonging to genera Sapajus and Alouatta. In a immunohistochemical test performed using streptavidin-biotin-peroxidase, 26.53% positivity was detected in 98 primates. Immunostainings revealed that infection differed among the lung (76.92%), liver (58.33%), heart (50%), brain (42.30%), and kidney (23.07%) tissues. Serology performed through indirect hemagglutination showed reactivity in 85.7% of the animals, all belonging to Sapajus sp., while the three primates that did not show reactivity (14.3%) belonged to Alouatta sp.

SUMMARYThe aim of this study was to assess the seroprevalence of the Toxoplasma gondii parasite in pork produced in France, and to determine infection risk factors. An innovative survey was designed based on annual numbers of slaughtered pigs from intensive and outdoor farms in France. A total of 1549 samples of cardiac fluids were collected from pig hearts to determine seroprevalence using a Modified Agglutination Test. Of those, 160 hearts were bio-assayed in mice to isolate live parasites. The overall seroprevalence among fattening pigs was 2·9%. The adjusted seroprevalence in pigs from intensive farms was 3·0%; the highest in sows (13·4%); 2·9% in fattening pigs and 2·6% in piglets. Adjusted seroprevalence in fattening animals from outdoor farms was 6·3%. Strains were isolated from 41 animals and all were genotyped by Restriction Fragment Length Polymorphism as type II. Risk-factor analysis showed that the risk of infection was more than three times higher for outdoor pigs, and that sows’ risk was almost five times higher than that of fattening animals. This study provides further evidence of extensive pork infection with T. gondii regardless of breeding systems, indicating that farm conditions are still insufficient to guarantee ‘Toxoplasma-free pork’.

Toxoplasma Gondii Infection

A serological survey of Toxoplasma gondii infection in blood donors was carried out in order to identify seroprevalence in Recife, Brazil. Sera from 160 individuals (119 male and 41 female) were evaluated by using a Toxoplasma IgG-antibody enzyme immunoassay (Denka Seiken Co., LTD., Tokyo, Japan). The seropositive percentual for males (79.0%) showed to be higher (p < 0.05) than for females (63.4%). This percentage increases with age, ranging from 18.2% to 92.6% for individuals aging under 20 and 40-50 years old, respectively. For women of childbearing age (18-40 years) it was found a prevalence of 51.6%.
