“…For example, the snail is the intermediate host of S. japonicum , and there are more snails in spring and autumn, so the prevalence of S. japonicum is relatively high in the two seasons. In this study, there was a significant difference in the prevalence of parasitosis between months, which is consistent with a previous study ( Wang et al., 2019 ). Additionally, a survey of helminths in goats in Hunan Province shows that the number and intensity of nematodes and cestodes peaked in summer and autumn, while the highest prevalence of trematodes was in winter ( Ma et al., 2014 ).…”

“…Hunan Province is one of the most important provinces in pork and mutton production, and wild snakes have been widely sold at food markets in some regions. Especially, foodborne parasites are usually zoonotic, so livestock usually can be infected with parasites, such as T. gondii , cysticercus, and Trichinella ( Cui et al., 2013 ; Jiang et al., 2016 ; Li et al., 2016 ; Tan et al., 2018 ; Wang et al., 2019 ). Eating undercooked meat is popular in some areas of this province, which increases the risk of human parasitic infection with parasites.…”

Great progress has been made in the prevention and treatment of human parasitic diseases in China over the past six decades, but parasitic diseases are still one of the most serious public health problems in the world. The specific prevalence of parasitic diseases varies in different provinces due to their geographical environment and the dietary habits of people. In this study, a total of 4,428 patients suspected to have parasitic infection by clinicians or themselves from January 1, 2016, to December 31, 2020 were recommended to our laboratory for further testing. In total, 5,246 samples including fecal, blood, and other body fluids were detected by etiological and immunological methods. Approximately 15.20% (673/4,428) of all suspected patients were infected by at least one species of parasite, and the overall positive rate of suspected patients from Hunan Province was 15.10% (594/3,933). A total of 18 species of parasites, namely, nematodes (4 species), trematodes (5 species), cestodes (4 species), protozoa (2 species), and medical arthropods (3 species), and 3 of them were imported parasites outside of Hunan Province. There are 9 species of foodborne parasites, accounting for 89.92% (464/516) of patients infected by one species of parasite. Common parasites in Hunan Province include plerocercoid, Paragonimus westermani, Clonorchis sinensis, cysticercus, Toxoplasma gondii, and Schistosoma japonicum. In this study, we found that the incidence of soilborne nematode infections has decreased significantly. However, foodborne parasites gradually become the main parasitic infections as well as multiple infections are becoming more common. Therefore, we should not only continue the prevention and control of soil-derived nematodes but also focus on the prevention and control of foodborne parasites in the future.

“…Previous studies in different countries reported that pigs reared in a free ranging or semi‐intensive system had a higher seroprevalence of T. gondii than those reared in an intensive system (Gebremedhin et al., 2015; Hove et al., 2005; Thakur et al., 2019; van der Giessen et al., 2007; Villari et al., 2009). The previous studies had also suggested other potential risk factors for the infection of T. gondii in pigs, such as biosecurity measures, management practices, the presence of cats, rodent control, carcass disposal and season (Ortega‐Pacheco et al., 2013; Wang et al., 2019). Such information is not available for this study, and further comprehensive epidemiological studies of pigs in India should also include these risk factors.…”

AimsToxoplasmosis is one of the most common food‐borne parasitic zoonosis, caused by Toxoplasma gondii, an obligate intracellular protozoan parasite. A cross‐sectional study was carried out to determine the seroprevalence of T. gondii and associated risk factors in pigs in Haryana, India.Methods and ResultsSerum samples were collected from 429 pigs from three agroclimatic zones (I–III) of Haryana and analysed for the presence of antibodies against T. gondii using a commercial indirect enzyme‐linked immunosorbent assay (ELISA). Anti‐T. gondii antibodies were detected in 106 animals (24.7%), with the highest seropositivity in zone II (31.3%) followed by zone III (24.4%) and zone I (18.3%). Risk factors associated with higher seropositivity in pigs were farm size (higher in large‐sized farms), age (higher in pigs >1 year of age), sex (higher in males), type of feeding (higher in combination of homemade and hotel waste) and housing (higher in free‐ranging pigs).ConclusionsThe findings of the study testify to the exposure of pigs (of all agro‐climatic zones) to T. gondii. Hence, the observations are of significant medical and veterinary importance for devising and implementing control measures to check the dissemination of toxoplasmosis to pigs and eventually to humans.

“…At the same time, there was no significant difference in the seroprevalence in different months. However, some studies have shown that the seroprevalence is probably related to seasons [17], and the reason for this difference may be due to different environments, temperatures, and various sample qualities. Moreover, studies have shown that high temperatures have little impact on the reduction in viability of T. gondii [15].…”

Seroprevalence of Toxoplasma gondii infection in sheep in Inner Mongolia Province, China

et al. 2020

Toxoplasma gondii is an important zoonotic parasite that can infect almost all warm-blooded animals, including humans, and infection may result in many adverse effects on animal husbandry production. Animal husbandry in Inner Mongolia is well developed, but data on T. gondii infection in sheep are lacking. In this study, we determined the seroprevalence and risk factors associated with the seroprevalence of T. gondii using an indirect enzyme-linked immunosorbent assay (ELISA) test. A total of 1853 serum samples were collected from 29 counties of Xilin Gol League (n = 624), Hohhot City (n = 225), Ordos City (n = 158), Wulanchabu City (n = 144), Bayan Nur City (n = 114) and Hulunbeir City (n = 588). The overall seroprevalence of T. gondii was 15.43%. Risk factor analysis showed that seroprevalence was higher in sheep ≥12 months of age (21.85%) than that in sheep <12 months of age (10.20%) (p < 0.01). Seroprevalence was higher in male sheep (18.76%) than females (12.80%) (p < 0.01). Barn-feeding sheep (23.13%) had higher prevalence than grazing sheep (10.94%) (p < 0.01). The seroprevalence was significantly different in different districts (p < 0.01). This study shows that sheep are exposed to T. gondii in Inner Mongolia, and provides a data reference for public health and disease control.
