“…This is in agreement with a preliminary work in which T. gondii seroprevalence of 69% was found in ocelots of the same region studied herein [21]. Although the previous result may seem incongruent with the low prevalence found in rodents, it is possible that low prevalence in prey may lead to high transmission if they are the main meat source for predators.…”

“…The weather at Soto La Marina is warm-moist, where temperature and rainfall ranges are 20–26 °C and 700–1100 mm, appropriate conditions for T. gondii transmission [16]. The study area was selected because two wildcat species have previously been recorded, jaguarundi ( Puma yagouaoroundi ) and ocelot ( Leopardus pardalis ), and a high prevalence of T. gondii infection was previously reported in the second species [5, 21]. …”

“…Although some authors have highlighted the theoretical role of rodents in the maintenance of T. gondii in wildlife, there are few reports of prevalence and distribution of this protozoan in wild felids [2]. A previous study in Soto La Marina, Tamaulipas, Mexico, demonstrated a prevalence of 69% of T. gondii infection in ocelots [21]. Although it is clear that these wild cats play an important role in the Toxoplasma wildlife cycle of this region, toxoplasmosis prevalence in the prey populations where these cats are the only possible definitive hosts is not known.…”

Toxoplasmosis seroprevalence in wild small rodents, potentially preys of ocelots in north-eastern Mexico

The aim of this study was to assess the prevalence of Toxoplasma gondii infection in rodents that coexist with ocelots in north-eastern Mexico. Eighty rodents of five genera were captured and their serum samples tested for specific IgG antibodies to T. gondii by in-house indirect ELISA using three different conjugates. Prevalences of 7% (3/44) and 33% (4/12) were found in Sigmodon hispidus and Liomys irroratus, respectively, and were significantly different. All Baiomys taylori and Oligoryzomys fulvescens were negative for the presence of anti-T. gondii IgG antibodies. The samples from Peromyscus spp. could not be analyzed because none of the three conjugates tested recognized their immunoglobulins. Infection was confirmed in one single specimen of L. irroratus by qPCR, which generated an estimate of 146 parasites per mg of muscle tissue. The results strongly support the notion of active T. gondii transmission between rodents and felines in this zone of Mexico and an important role of some rodent species in the sylvatic cycle of T. gondii.

Toxoplasmosis is a parasitic disease widely distributed throughout the world, infecting a wide variety of animal species including humans. In Mexico, this parasite has been detected in different parts of the country, particularly in the tropical areas where the parasite can remain infective for long periods of time due to the environmental conditions (i.e. high temperature and humidity over the whole year). Several epidemiological studies have been conducted in both human and animal populations, but despite the wide distribution of the agent in the country, there is a significant lack of knowledge on the parasite transmission, treatment alternatives and control measures. The lack of feral cat populations and control measures in sites of meat production for human consumption are playing a role that has led to the wide spread of the disease in the country, particularly in tropical areas of Southeastern Mexico. For these reasons, this manuscript aims to review the published information on relevant epidemiological aspects of infection with T. gondii in humans and animals from Mexico.

“…The domestic cat (Felis catus) is the definitive host of T. gondii, an intracellular protozoan of worldwide distribution, although neotropical felids are also recognized as definitive hosts (JEWELL et al, 1972), emphasizing the importance of wild felines in the epidemiology of the agent in environments where cats do not exist (RENDÓN-FRANCO et al, 2012). The presence of anti-T. gondii antibodies has been reported in felids and canids in Brazilian zoos (SILVA et al, 2001;MATTOS et al, 2008;ANDRÉ et al, 2010), including seropositive captive jaguars.…”

Toxoplasma gondii, Neospora caninum and Sarcocystis neurona are related apicomplexan parasites that cause reproductive and neurological disorders in a wide range of domestic and wild animals. In the present study, the immunofluorescence antibody test (IFAT) was used to investigate the presence of antibodies against T. gondii, N. caninum and S. neurona in the sera of 11 free-living jaguars (Panthera onca) in two protected areas in the Pantanal region of Mato Grosso state, Brazil. Ten jaguars (90.9%) showed seropositivity for T. gondii, eight (72.7%) for S. neurona, and seven (63.6%) for N. caninum antigens. Our findings reveal exposure of jaguars to these related coccidian parasites and circulation of these pathogens in this wild ecosystem. To the best of our knowledge, this is the first serological detection of N. caninum and S. neurona in free-living jaguars.
