Introduction: There are a limited number of studies of the agricultural population about the prevalence of Toxoplasma gondii (T. gondii) infection throughout the world. The aim of this study was to determine the prevalence and risk factors of toxoplasmosis in female farmworkers in the southeastern region of Turkey. Methodology: The optimum sample size was determined using the Epi Info Program, and blood samples were collected from 684 women of reproductive age. Serum samples were analyzed by qualitative and quantitative methods for anti-T. gondii IgG and IgM antibodies with a commercially available enzyme immunoassay. Questionnaires through which socio-demographic information was collected were applied during face-to-face interviews of subjects who gave their consent to participate in the study. Crude odds ratios (ORs) and 95% confidence intervals (CIs) were calculated, and Chi-square analyses and logistic regression were performed. Results: Of the 684 women, the prevalence of toxoplasmosis was determined to be 58.3% and 1% for IgG and IgM, respectively. Employment as a seasonal farmworker, increasing age, and having had three or more pregnancies were found to be the crucial associated risk factors that affect the prevalence of T. gondii infection (p < 0.05). In contrast to these, the provincial development level was found to be a confounding factor. There was no association between toxoplasmosis and household size, education attainment, and poverty in the bivariate analyses. Conclusions: The findings show that control and serological screening programs should be implemented nationwide in Turkey for the reliable and fast detection of congenital Toxoplasma infections.

AbstractA cross-sectional study was carried out to determine the seroprevalence of Toxoplasma gondii and associated risk factors in pigs in the largest pork-producing region in Cuba. Serum samples from 420 pigs, including 210 sows and 210 post-weaning pigs, were tested for antibodies against T. gondii using a commercial indirect enzyme-linked immunosorbent assay. Anti-T. gondii antibodies were detected in 56 animals (13.3%, 95% CI: 10.1–16.6). A generalized estimating equations model revealed that the risk factors associated with higher seropositivity in pigs were altitude (higher in farm’s location < 250 m above sea level (masl) versus ≥ 250 masl) and age (higher in sows compared to post-weaning pigs). The results indicated that this protozoan parasite is widely distributed on pig farms in the study area, which is a public health concern since the consumption of raw or undercooked pork meat products containing tissue cysts is considered one of the main routes of T. gondii transmission worldwide. Control measures should be implemented to reduce the risk of exposure to T. gondii in pigs in Cuba.

Much epidemiological information concerning brucellosis generally depends on the evaluation of hospital-based retrospective data. The aim of this study was to determine the prevalence and risk factors of brucellosis in female farmworkers in the south-eastern region of Turkey (GAP) in order to obtain a more representative analysis. Our representative community-based cross-sectional study was conducted during four months of 2013, in all nine GAP provinces. An optimum sample size was determined and blood samples were analysed from 707 reproductive-age female farmworkers using the Rose Bengal (RBT) and standard (SAT) agglutination tests. Sociodemographic information was collected during face-to-face interviews with consenting subjects. Crude odds ratios and 95% confidence intervals were calculated, and chi-square analyses and logistic regression were performed. Employment as a seasonal farmworker and having had five or more pregnancies were the only risk factors found to be significant. This study implies much greater priority needs be given to the control, early diagnosis and treatment in this population.

Introduction: Toxoplasma gondii is an obligate intracellular protozoan parasite that represents an actual public health problem. Nangarhar is a tropical region in southern of Afghanistan, due to importance of abortions by Toxoplasmosis and absence of study evidences in this field in Nangarhar province, this cross sectional hospital based research was accomplished. Purpose: The aim of this study was to estimate the prevalence of T. gondii and possible risk factors associated with the infection among the women who have abortion in Nangarhar province. Methodology: Designed questionnaire for obtaining history of abortion and interviewing with aborted patients were use, the convenient sampling method as well using Latex agglutination Lab Test (LAT) a total of 100 serum samples of miscarriage women from Nangarhar different districts were collected and tested for Toxoplasma gondii antibodies. All collected data were analysed using ANOVA. SPSS Program.Findings: The overall prevalence of toxoplasmosis in mentioned women was 47% (47/100 cases).  From 47 positive cases 17 (34%) was in women resident in Urban areas and 30 (60%) was those resident in Rustic areas. The prevalence rate showed there was significant differences between women resident in Rustic and those in urban areas. The people who are living in rustic area (30%) were more exposed to infection than those who were living in urban area (17%) (P < 0.015). Higher prevalence was observed in 25-30 years old group than the others (P <0.05). The result showed that Contact with raw or uncooked meet, water and soil, contaminated food and animals were significant (P <0.05).

Toxoplasma gondii is an intracellular parasite that is extensively prevalent globally. Studies have indicated the presence of T. gondii infection in animals in some provinces of China, but little is known about T. gondii infection in yaks (Bos grunniens) on the Qinghai–Tibetan Plateau. In the current study, to determine the seroprevalence and associated risk factors of T. gondii, a total of 2784 serum samples were collected from 18 different sampling sites in eight counties of the Qinghai and Tibet regions of China from 2018 to 2019. Serum antibodies against T. gondii were detected in 261 yaks (9.38%) via enzyme-linked immunosorbent assay (ELISA). We found that seroprevalence differed significantly among different counties (ranging from 5.41% in Gangcha to 19.79% in Datong), by year in the Tibet Autonomous Region (from 2.34% in 2018 to 13.24% in 2019), and by age (from 5.59% in 0 < year ≤ 1 to 11.76% in year > 7) (p < 0.05). Climate, geographical conditions, and age are the main factors influencing T. gondii infection in yaks in these regions. Therefore, our study provides a data reference for public health and prevention of yak toxoplasmosis.

This study was conducted to characterize the epidemiology of bovine brucellosis in the state of Pernambuco, Brazil. The state was divided into three regions, and in each region, approximately 300 properties were randomly sampled. From these selected properties, a pre-established number of animals were randomly selected and blood serum samples were obtained. A total of 3,901 animals were selected from 900 properties. For each selected property, an epidemiological questionnaire was administered to assess the type of farming, the animal husbandry practices and the sanitary practices that could be associated with the presence of brucellosis infection. The testing protocol consisted of screening the samples with a buffered acidified plate antigen test and retesting the positive samples with a complement fixation test (CF). One positive animal was enough to define an infected herd. The prevalence rates of infected herds and animals in the state were 4.5% [3.2; 6.4%] and 1.4% [0.7; 2.7%], respectively. By region, the prevalence rates of infected herds and animals, respectively, were as follows: Zona da Mata, 3.3% [1.8; 6.1%] and 1.7% [0.5; 3.0%]; Agreste, 7.4% [4.9; 10.9%] and 1.9% [0.8; 3.0%]; and Sertão, 1.3% [0.5; 3.5%] and 0.7% [0.0; 1.6%]. Flooded pastures (OR = 2.86 [1.37; 6.42]) and the presence of 13 or more females in the herd (3rd quartile) (OR = 2.65 [1.19; 5.89]) were identified as risk factors. The existence of veterinary care emerged as a protective factor against bovine brucellosis in the state of Pernambuco (OR = 0.24 [0.10; 0.58]).
