“…Toxoplasmosis is a zoonosis caused by the protozoan Toxoplasma gondii affecting mammals and birds worldwide ( 24 ). Human infection occurs primarily as a result of the ingestion of undercooked meat containing tissue cysts or through consumption of food or water polluted with faeces of felids carrying T. gondii oocysts.…”

Introduction Toxoplasma gondii is one of the most prevalent zoonotic protozoan parasites worldwide and affects the vast majority of warm-blooded animal species, including humans. Postnatal infection in humans occurs through the ingestion of sporulated T. gondii oocysts or via the oral intake of parasite tissue cysts during the consumption of raw or undercooked meat. In this regard, given their high exposure to oocysts, chickens (Gallus domesticus) raised on the ground constitute a potential source of T. gondii. Material and Methods For the first time in Spain, a survey was undertaken in commercial retail free-range poultry. A total of 50 thighs from different animals were analysed. The samples were homogenised and an acid pepsin digestion procedure was applied prior to molecular analysis. Toxoplasma gondii DNA was isolated from meat by qPCR. Two sets of primers were used for DNA amplification targeting the specific sequence of a 529 bp repeat element and another set of primers was utilised for the surface antigen protein-1 gene. Results DNA extracted from 5 out of 50 tissue samples was positive for both genes by qPCR amplification. Conclusion The 10% prevalence of Toxoplasma infection found in commercial free-range chickens raises public health issues.

“…Immunocompetent individuals infected with T. gondii rarely experience clinical disease. Most infections are subclinical and only 20% of infected humans show mild or more pronounced clinical symptoms and signs ( Robert-Gangneux et al, 2015 ; Montoya et al, 2019 ). Humans mainly become infected by ingesting raw or undercooked mammalian or poultry meat containing cysts with bradyzoites, as well as through ingestion of food or water contaminated with sporulated oocysts ( Montoya et al, 2019 ).…”

“…An acute infection with Toxoplasma gondii during pregnancy can lead to severe congenital complications for the fetus, with the highest risk of complications in the first trimester compared to the third trimester. However, the risk of infection increases as the pregnancy progresses [7,8]. Congenital complications include seizures, deafness, blindness, mental retardation and stillbirth [9,10].…”

Introduction Assessing the knowledge and practices of healthcare workers regarding Toxoplasma gondii infection, diagnosis, treatment, and control is crucial for developing an effective management strategy. Methods A cross-sectional study was conducted among 175 healthcare workers at Ndola Teaching Hospital and Namwala District Hospital in Zambia from September 2021 to April 2022. Results More than half (57.1%) of the respondents were males. Overall, 46(26.3%) and 68 (38.9%) respondents reported good knowledge and practices, respectively. Respondents with a higher number of years of experience (AOR = 0.86, 95% CI: 0.77–0.97), who were nurses than clinicians (AOR = 0.17, 95% CI: 0.007–0.41) and working at Ndola teaching hospital than Namwala hospital (AOR = 0.34, 95% CI:0.13–0.89) were less likely to have good knowledge. Respondents with a degree qualification than a diploma (AOR = 3.04, 95% CI: 1.09–8.47) were more likely to have good knowledge. Respondents from Ndola teaching hospital than Namwala hospital (AOR = 0.40, 95% CI: 0.17–0.92) were less likely to have good practices. Conclusion Our study revealed that healthcare workers had low levels of knowledge and poor practices, which could have negative implications for the management of toxoplasmosis. To improve their knowledge and practices, continuous medical education in Toxoplasma related aspects is recommended for in-service healthcare workers.
