“…Many studies have been carried out in recent years on the prevalence of Toxoplasma gondii antibodies in free-range and bred boar in many regions of the world, including Japan [42], the United States [27,28,30,43], Argentina [6], Brazil [44], China [45,46], and Korea [35,47]. Numerous studies have also been conducted in Europe.…”

Introduction and objective. Toxoplasmosis is an important zoonosis caused by a protozoan, Toxoplasma gondii. Raw or undercooked venison may be a source of infection in humans. The aim of the study was to determine the prevalence of T. gondii antibodies in wild boar from the Strzałowo Forest Division of the Warmia and Mazury Region of Poland. Materials and method. A total of 90 samples were collected from 50 wild boar: 40 from both tongue and diaphragm muscles, 4 from diaphragm muscles and six from tongue muscles. Samples were analyzed using the commercial PrioCHECK® Toxoplasma Ab porcine ELISA, according to the manufacturer's instructions. Results. T. gondii antibodies were detected in 24 of 50 (48%) tested animals. T. gondii antibodies were detected in 40 of 90 (44.4%) tested samples (21 of tongue muscles and 19 of diaphragm muscles). In the 40 wild boar that provided samples of meat juice from the tongue and diaphragm muscles, specific antibodies were more prevalent in the tongue (20 of 40 animals-50%) than in the diaphragm muscles (17 of 40 animals-42.5%). Conclusions. The study revealed a high percentage of wild boar seropositive to T. gondii. Muscle samples to obtain meat juice are easily available and simple to collect, even on the hunting grounds, which makes them suitable material for detecting T. gondii antibodies in wild boar. Wild boar are essential to T. gondii circulation in the environment, and raw or undercooked venison may be a source of human infections with this parasite.

“…Exposure to infected cats by these women could lead to severe outcomes to her carried fetus. Many studies reported Toxoplasma infection in animals for human consumption (Bangoura et al, 2013; Hill and Dubey, 2013; Kang et al, 2013; Lopes et al, 2013), 12.2% of pregnant women who consume raw meat especially Malaysian who were graduate from primary school and Thai's who were in age group 20–29, single, graduate from tertiary education and in their first semester of pregnancy could be at risk for Toxoplasma infection.…”

Toxoplasma gondii, is one of the infectious agents of congenital TORCH infections, causes severe clinical outcomes in fetus and newborns. Nevertheless this life-threatening parasitic disease is preventable by simple preventive measures related to lifestyle during pregnancy. We aim to study on the knowledge about toxoplasmosis and practices that prevents this infection among the pregnant women. Total of 2598 pregnant women from Malaysia, Philippines, and Thailand were randomly surveyed to determine the knowledge and their practices on Toxoplasma infection. The questionnaire covered respondents' general information and knowledge on plausible risks factors, symptoms, timing of infection, prevention knowledge, and preventive behavior regarding Toxoplasma infection. Majority of these pregnant women were in their age group of 20–29 years (50.9%), completed secondary level of education (51.7%), in their second trimester of pregnancies (38.1%), non-parous (36.6%), and had no history of abortion (90.4%). Based on this survey, only 11% of these pregnant women had read, heard, or seen information regarding toxoplasmosis and 3.5% of them were aware of being tested for the infection. A small percentage of these pregnant women knew that T. gondii were shed in the feces of infected cats (19.4%) and sometimes found in the raw or undercooked meat (11.0%). There was 16.1% of responding women knew that toxoplasmosis is caused by an infection. Demographic profiles such as age group, level of education, pregnancy term, and number of children of the pregnant women showed significant association with their responses toward prevention knowledge and preventive behavior related questions (P < 0.05). Thus, it is suggested that health education on toxoplasmosis and primary behavioral practices should be consistently offered to reproductive age women in general and pregnant women in particular. This information could help to reduce vertical transmission of Toxoplasma infection during pregnancy.

“…In Brazil, there is a lower prevalence (4.5%) of infection by T. gondii in farm animals (4.5%) (FORNAZARI et al, 2009). However, in southern Brazil, there is a higher prevalence (14.28%) of infection in feral animals (SANTOS et al, 2016), indicating that domestic animals (BAI et al, 2017) are less likely to be infected than wild animals (DEKSNE & KIRJUSINA, 2013;KANG et al, 2013).…”

Detection of Toxoplasma gondii infection in feral wild boars (Sus scrofa) through indirect hemagglutination and PCR

Wild boars (Sus scrofa) have become an important invasive species in all Brazilian regions. Increase in their population causes damage to rural properties, as they invade and destroy crops. To protect their crops and farm animals, producers hunt wild boars and often consume the product without any sanitary control, becoming exposed to various types of pathogens, including Toxoplasma gondii. Sanitary evaluations of these animals are scarce, especially in relation to the protozoan T. gondii. This study aimed to evaluate the occurrence of this pathogen in wild boars in Brazil. We analyzed 122 blood samples from wild boars (blood clots and serum), collected between 2014 and 2016 in five Brazilian states, using polymerase chain reaction (PCR) and indirect hemagglutination (IH) techniques. In total, 33 (27%) samples were positive by at least one test, 16 (13.1%) were positive by PCR, 19 (15.6%) were positive by IH, and only 2 (1.6%) were positive by both tests. The lack of sanitary management of feral animals increases the incidence of infections, and the consumption of raw or inadequately cooked meat may become a potential source of infection for humans in Brazil.
