“…In many studies, contaminated drinking water, close contact with cats as domestic pets and eating uncooked meat have been implicated as sources of Toxoplasma infection in humans worldwide (23)(24)(25)(26)(27), but there was no statistically significant association between these risk factors and Toxoplasma seropostivity in the current study. In this study specific IgG and IgM antibodies of T. gondii in the experimental and control groups were detected by ELISA technique.…”

Background:Toxoplasmosis is an opportunistic infection caused by Toxoplasma gondii. That is asymptomatic in the majority of patients, but it can be life threatening in immune-compromised subjects, such as patients with HIV and organ transplant recipients. Objectives: This study aimed to determine the Toxoplasmosis in Renal Transplant Recipients in Ahvaz, South-West of Iran. Materials and Methods: A total of 100 patients and 100 healthy subjects participated in this study. The specific IgG and IgM antibodies of T. gondii were detected in the two groups by ELISA and the presence of T. gondii in the blood samples was evaluated by GRA6 PCR. Results: 34 (34%) of the renal transplant recipients and 26 (26%) of the control group were positive for anti-Toxoplasma IgG. In addition 18 (18%) of the renal transplant recipients and 4 (4%) of the control group were positive for anti-Toxoplasma IgM. For both values of the antibodies, differences were statistically significant (P < 0.025 and P < 0.001 respectively). The PCR results indicated the presence of T. gondii parasite in 2 blood samples of recipients, but not in those of the healthy control. Conclusions: According to the findings of the current study, renal transplant recipients have a higher prevalence of toxoplasmosis than healthy people and also there is disseminated infection in the patients. Therefore to prevent the severe complications screening and follow up of renal transplant recipients for toxoplasmosis should not be neglected.

“…If one considers that infection by T. gondii occurs during different stages of the etiologic agent's lifecycle, i.e., as a result of consumption of food contaminated with oocysts, direct contact with oocysts from cat feces on the ground or by ingesting cysts containing bradyzoites in previously infected animal tissues [14][15][16], the absence of an association between the high prevalence in the rural area studied and these behavioral factors is curious. With regard to contact with domestic animals (cats and dogs), a relatively large percentage of the study population (53.2%) reported contact with the former, although the corresponding figure for dogs was higher (72.2%).…”

Abstract:Background: Toxoplasmosis is caused by the intracellular protozoan Toxoplasma gondii, which has a worldwide distribution. Here, in the first study of asymptomatic infection by this protozoan in the state of Espírito Santo, Brazil, we present an analysis of the prevalence and annual incidence of asymptomatic cases of toxoplasmosis in a rural area of this state.Methods: Plasma samples from 79 individuals who had responded to questionnaires were analyzed by IgG ELISA, and positive cases were subjected to an IgG avidity test. Follow-up lasted one year and consisted of quarterly visits.Results: Of the 79 individuals assessed, 67.1% were positive for IgG anti-Toxoplasma gondii, and the incidence was 6.2 per 100 person-years of observation. No statistically significant association was found between toxoplasmosis and contact with cats or between toxoplasmosis and consumption of pork, mutton or lamb, even if these were undercooked or raw. According to the multivariate analysis, the only risk factor related to infection appears to be increasing age (OR = 1.086). Confirming the data in the literature, the statistical analysis showed that with every additional year of age the risk of contracting toxoplasmosis increase by 8.6%. Conclusion:The inhabitants of rural communities in the mountainous region of Espírito Santo are very exposed to Toxoplasma gondii and know very little about the disease, making them vulnerable to exposure.

“…The relative importance of meat or oocysts as a source of human infection is unknown. An outbreak of unilateral chorioretinitis owing to T. gondii was reported in three patients from Korea who ingested raw liver and spleen from a wild pig (Choi et al 1997). Although no other outbreaks have been reported from wild boar, the generally high serological prevalence of T. gondii in these animals indicates that consumption of raw or rare wild boar meats is likely to lead to an infection with T. gondii.…”

Wild boars (Sus scrofa) are indigenous in many countries in the world. These free-living swine are known reservoirs for a number of viruses, bacteria and parasites that are transmissible to domestic animals and humans. Changes of human habitation to suburban areas, increased use of lands for agricultural purposes, increased hunting activities and consumption of wild boar meat have increased the chances of exposure of wild boars to domestic animals and humans. Wild boars can act as reservoirs for many important infectious diseases in domestic animals, such as classical swine fever, brucellosis and trichinellosis, and in humans, diseases such as hepatitis E, tuberculosis, leptospirosis and trichinellosis. For examples, wild boars are reservoirs for hepatitis E virus, and cluster cases of hepatitis E have been reported in Japan of humans who consumed wild boar meat. In Canada, an outbreak of trichinellosis was linked to the consumption of wild boar meat. The incidence of tuberculosis owing to Mycobacterium bovis has increased in wild boars, thus posing a potential concern for infections in livestock and humans. It has also been documented that six hunters contracted Brucella suis infections from wild swine in Florida. This article discusses the prevalence and risk of infectious agents in wild boars and their potential transmission to livestock and humans.
