Toxoplasma gondii infections in sheep and goats are important economically and for public health for many countries, including Romania. In this study, seroprevalence and associated risk factors for T. gondii infection were determined in 2500 sheep and 500 goats from three counties in the Banat region of Romania. Antibodies to T. gondii were found in 1266 of 2500 (50.64%) sheep and in 375 (75%) of 500 goats, by using a commercial (IDEXX) ELISA. To evaluate the epidemiological status of the infection, some risk factors for ovine and caprine T. gondii infections were assessed. The main risk factors associated with T. gondii infections were breed, age, and the presence of cats in the farm. Seroprevalence was higher in animals older than three years and in purebred versus mixed breed animals. This is the first detailed study of risk factors associated with T. gondii seroprevalence in sheep and goats in Romania.

Toxoplasma Gondii Infection

Abstract Little is known about Toxoplasma gondii infection among cattle living in the Cerrado (Brazilian savanna) biome in Brazil. In particular, there is no epidemiological data relating to infection in quilombo lands, i.e. areas settled by Afro-descendants of escaped slaves. The aim of this study was to determine the prevalence, spatial distribution and risk factors associated with T. gondii infection among cattle in the Kalunga quilombo, in the Cerrado biome. Blood samples were collected from 1533 cattle for antibody detection using the indirect fluorescence antibody test (IFAT). The study area was subdivided into five macroregions to determine the spatial distribution of infection. An objective questionnaire was applied to the cattle owners to evaluate risk factors, which were analyzed using univariate analysis and logistic regression. The prevalence of T. gondii infection among cattle was 8.93% (137/1533), and antibodies were found in 49.6% of the herds (66/133), in all macroregions. The risk factors associated with T. gondii infection in cattle were the following: number of animals in the herd (OR: 30.56), purchase of cattle (OR: 2.57), age group (OR: 1.95) and average annual temperature (OR: 1.77). Thus, the occurrence rate, spatial distribution and risk factors associated with T. gondii infection among cattle in the Kalunga quilombola community are documented here, for the first time.

Toxoplasma Gondii Infection

Abstract This study aimed to investigate the frequency of anti-Toxoplasma gondii antibodies in serum from 629 chickens on 39 family farms in seven municipalities in the semiarid region, Pernambuco, Brazil, and to identify risk factors associated with T. gondii infection. The risk factors were studied in 421 samples from 29 farms. Anti-T. gondii antibodies were investigated by indirect fluorescent antibody test with a 1:16 cutoff. The frequency of positive chickens was 27.9% (176/629) and 94.8% of the farms studied had chickens infected by T. gondii. Multivariate analysis showed variables significantly associated with anti-T. gondii antibodies in serum: slaughter of animals on the farm, reproductive disorders in sheep, consumption of fetal adnexa and placentas by chickens, presence of sheep in the property and birth of sheep the property. The results suggest that there is a complex relationship between general management practices for different animal species raised on the same farm and the prevalence of T. gondii infection in chickens. In addition, the results draw attention to the risk of human infection by T. gondii via consumption of infected chicken meat, because the farming conditions and the low human development indices observed in the region studied result in inappropriate meat preparation practices.

Abstract Background Exposure to Toxoplasma gondii infection is prevalent in up to 90% of the world’s population. Severe infections can be fatal and deforming in neonates. Cats serve as reservoirs for T. gondii infections. Even though many Ghanaians have cats as pets in their homes only few studies have been undertaken to assess the prevalence of the disease in Ghana. The objective of the study was to determine the seroprevalence of T. gondii infection and its associated risk factors among pregnant women seeking antenatal care at the Goaso Municipal Hospital, in Asunafo North District of the Ahafo Region and the St. Michael’s Catholic Mission Hospital in the Bosomtwe District in the Ashanti Region of Ghana. Methods A cross-sectional study involving 266 (146 from Asunafo North District and 120 from Bosomtwe District) pregnant women who consented to participate in the study was undertaken. To gather information on associated risk factors, structured questionnaire was administered to the participants. In addition, 3 mls of venous blood was collected from each participant for anti-T. gondii IgG and anti-T. gondii IgM antibody analyses using ELISA. Results A total of 64.3% (171/266) of the study participant were positive for anti-T. gondii IgG and 26.3% (70/266) were positive for anti-T. gondii IgM antibodies. This signifies that 64.3% of the study population have been exposed to the infection and 26.3% were actively infected. There were no differences (P=0.383) between the overall T. gondii seroprevalences in the two Districts. There was a significant difference between antibody concentration levels and age in the Bosomtwe District in Ashanti Region. No association (OR<1) was found between the seroprevalences and the suspected risk factors assessed in this study. Conclusion The study showed that the seroprevalence of T. gondii among pregnant women visiting the two health facilities in the two Regions was higher compared to the 30%-65% reported as the global population infection status. This study provides baseline data for future studies in the other Districts and Regions in the country to ascertain the overall seroprevalence in Ghana.
