“…Although the data obtained in this study are local, it is important to underscore the presence of this pathogen in sheep flocks in northeastern Brazil. From an epidemiological standpoint, the positivity identified in slaughtered animals is a cause for concern, since part of the carcass of these animals are frequently used to feed dogs (Souza et al, 2019), the definitive host of this protozoan (Dubey, 1999). In fact, it is known that the most common route of transmission to dogs is through the ingestion of raw or undercooked meat containing cysts (Paradies et al, 2007).…”

Neospora caninum is a protozoan that causes reproductive disorders in herbivores. Domestic and wild dogs have been considered its definitive hosts, and when these animals are affected, they may suffer from a neuromuscular disease. Recently, this infection has also gained significance in small ruminants. Although neosporosis is already a proven cause of mortality in lambs and congenital infection can occur, this parasite has only recently been considered a cause of abortion in these animals. The aim of this study was to detect anti-N. caninum antibodies in slaughtered sheep. Serum samples (n = 100) collected in a slaughterhouse located in the municipality of Palmeira dos Índios (09°24'26" S and 36°37'39" W), state of Alagoas, northeastern Brazil, were used in this study. Anti-N. caninum antibodies were detected by means of the Immunofluorescence Antibody Test (IFAT). The cutoff point was set at 50 and samples were titrated up to 800. Anti-N. caninum antibodies were detected in 13% (13/100) of the tested samples, 7.69% of which came from male sheep (1/13) and 92.31% (12/13) from females. Titers ranged from 50 to 800, with the majority of animals (46.15%; 6/13) presenting the maximum one (i.e., 800). Data herein reported demonstrated the circulation of N. caninum parasites among sheep in the study area. These findings are pivotal to improve the knowledge about the dynamics of this pathogen in an ovine population. Therefore, it is crucial to adopt sanitary measures to prevent infection by this parasite and thus reduce its economic impact on ovine production.

“…In northern Iraq, a serosurvey of sheep and goats revealed seroprevalences of Toxoplasma infection of 42.1% and 36.1%, respectively [ 13 ]. In addition, T. gondii infection in canine was detected in Brazil and revealed a seropositivity of 9.54% [ 14 ]. The seroprevalence of T. gondii in animals ranged from 6% to 33%, according to statistical analysis of the positive rates of T. gondii infection in five different animal species in the Nordic-Baltic region [ 15 ].…”

Background: Toxoplasma gondii is classified as intracellular protozoa and is one of the major zoonotic parasites. Most warm-blooded intermediate hosts, including humans, are commonly infected by this parasite. The epidemiology of T. gondii infection in Egyptian horses is currently poorly understood. Methods: 420 blood samples were randomly collected from horses raised in four governorates in Northern Egypt (110 each from Giza and Kafr El Sheikh, and 100 each from Qalyubia and Gharbia) to investigate the existence of antibodies against T. gondii using a commercial ELISA kit, and to ascertain the risk factors for the infection. Results: the antibodies for T. gondii were found in 16.2% (68/420) of the examined horses, with no significant differences among the four studied governorates. The highest prevalence rate was observed in Giza. The results revealed that sex, breed, age, and contact with domestic ruminants or cats were recognized as potential risk factors. The high prevalence rate was found in mixed breed horses (OR = 2.63, 95% CI: 0.95–7.26), mares (OR = 2.35, 95% CI: 1.31–4.19), and horses aged over 10 years (OR = 2.78, 95% CI: 1.30–3.44). Moreover, the likelihood of seropositivity for T. gondii infection was higher in horses raised in environments with cats (OR = 1.97, 95% CI: 1.13–3.44, p = 0.017) or domestic ruminants (OR = 2.16, 1.21–3.86, p = 0.010). This report confirms that horses in Northern Egypt are exposed to T. gondii and thus raises the possibility that people and other animals could contract the disease. Conclusions: routine examination and management of T. gondii infection in horses in these governorates is advised.

“…Using the Sabin–Feldman dye test, the seroprevalence in wild sika deer surveyed in Japan was 47.5% 8 . The prevalence of T. gondii infection in dogs has been investigated in Brazil, which detected a seroprevalence of 9.54% in samples 9 . In Nordic-Baltic region, the positive rates of T. gondii infection in five animal species were statistically analyzed, which draw a conclusion that the seroprevalence of T. gondii in animals ranged from 6 to 33% 10 .…”

Toxoplasma gondii, one of the important zoonotic parasites, has been detected in lots of hosts including humans, with a widespread prevalence. The products of equids, such as meat and milk, have been closely related to humans’ life. As the intermediate hosts, little is known about equids toxoplasmosis in Jilin province. Therefore, the present study aimed to evaluate the occurrence and risk factors of Toxoplasma gondii infections in equids from Jilin, northeastern China. In this study, a total of 245 blood samples of equids (192 horses, 25 donkeys and 28 mules) were collected from six localities in Jilin Province from March 2018 to August 2020 and detected by PCR. The occurrence rate of T. gondii B1 gene was analyzed using multivariable logistic regression to evaluate risk factors associated with the positive rates in equids. Among 245equids, T. gondii molecular occurrence was 9.0% (22/245). The highest positive rate was observed in equids from Dongfeng (16.3%) followed by Taonan (10.0%), Wangqing (8.3%), Antu (8.0%), Tonghua (8.0%) and Shulan (2.3%). Statistical analysis revealed that farming model and region may be two main risk factors. Data analysis indicated that the positive rate in captive farm (3.2%, 95% CI: 0.0–6.7%) was significantly lower than those in cage-free farm (P < 0.05), and the region of Shulan was protective factor (OR: 0.063, 95% CI: 0.007–0.559).The results of our study alert people to be aware that the present of equids T. gondii infection in this region, and contribute to a prevention and treatment program for toxoplasmosis in Jilin, China.
