Sadrebazzaz et al (48) reported a seroprevalence of 15.1% in the prevalence study of 810 cows in Iran and the seroprevalence in 139 aborted cows was found as 19.4%. ?avd?r and Kemer 4%, Karamanl? and Burdur Centrum 2%, according to districts. Conclusion: The seroprevalence of was revealed in Burdur region. It was emphasized that contamination should not be ignored in reproductive problems, especially in abortion cases. is an obligate intracellular and tissue cyst-forming apicomplexan parasite, has an heteroxenous life cycle between canids as definitive and a variety of warm-blooded animals as intermediate host. Clinical neosporosis Trigonelline Hydrochloride has been reported in sheep, goat, deer and horses (4). It has emerged as a major cause of economic losses, generally related to abortion, stillbirth Trigonelline Hydrochloride and other reproductive problems in most common intermediate host dairy and beef cattle all over the world (4, 5). The horizontally transmission of occurs by ingestion of tissue cysts or tissues infected with tachyzoites for definitive host canids and ingestion of food or drinking water contaminated by sporulated oocysts for cattle and other intermadiate hosts. Also it can be transmitted vertically (transplacentally or congenitally) to the fetus; as exogenous after ingestion of sporulated oocyst by pregnant dam or as endogenous in a chronically (persistently) infected dam by reactivation of the contamination during pregnancy (6). Generally neosporosis occurs latent and asymptomatic in non-pregnant cattle, however abortions caused by can be observed from 3 months to term (often occurs at 5C6 months) at any age of cow sporadically, endemically or epidemically (4). in maternal blood to differentiate infected from noninfected animals (8). Serological assays provides Rabbit polyclonal to USP33 a cost advantage compared to other tests. The most commonly commercialized serologic assessments used for this purposes are ELISAs. Among the serological methods, ELISA is the most suitable for high throughput screening of antibodies against (11), particularly for survey studies in large-scale herds (12). Hence, commercially available monoclonal antibody-based Competitive ELISA (cELISA) (13) was also used in the present study to detect of serum antibodies against in cattle. The present study was conducted to investigate the seroprevalence in Burdur region and its relationship with reproductive problems such as abortion and infertility. Materials and Methods Study area, animals and blood samples The study was based on data gleaned from a total of 400 cows from different ages and breeds from Burdur city center, Bucak, Aglasun, Yesilova, Kemer, Cavdir, Karamanli and Golhisar districts of Burdur province of Turkey. Blood samples were collected from vena jugularis into sterile serum tubes from 49 aborted, 58 infertil, 48 pregnant and 245 healthy cows for the findings of reproductive anamnesis. The cows examined were randomly selected. Serum has been obtained by removing after centrifugation of blood samples at 3000 rpm for 10 min and stored at ?20C up to the serological analysis were applied. Serological test The antibodies to in Trigonelline Hydrochloride sera samples were detected by using a commercially available competitive cELISA test kit (VMRD, Pullman, USA). The serological analysis were performed following the manufacturers instructions. To determine the values for optical density (OD), a microplate reader (Bio-Tek Instruments, ELX800, USA) was used by seting at 620 nm wave length. The formula: Inhibition (%) = 100 – [(Sample O.D. X 100) (Mean Unfavorable Control O.D.)] was used to assess the percent inhibitions of antibodies. According to the manufacturer; the samples with 30% inhibition values were considered as positive while with< 30% inhibition values were considered as unfavorable. Statistical analysis Statistical analysis was performed using the Pearson chi-square test with the help of MiniTab16 Statistics program. The Chi-square test was applied to compare the prevalences of seropositive cows according to age, breed and reproductive anamnesis. The seroprevalences in cattle in Burdur region are presented in Table 1, according to age, breed, districts and reproductive anamnesis. As seen in Table 1, no statistically significance was observed among seroprevalences of age groups and breeds. The seroprevalence was significantly higher in aborted than in non-aborted (total number of infertile, pregnant and healthy) cows. Also a statistically significance (among aborted and healthy animals. Table 1: Seroprevalence of in cows in Burdur region with regard to origin, breed, age and reproductive anamnesis (no)(no)(%)contamination is admitted as one of the most common and important disease, cause sporadic and endemic bovine abortion and reduced reproductive efficiency in dairy and beef cattle worldwide (4, 14). An apicomplexan protozoon has been reported in rates of 36.8% in Spain (15), 57.5C59% in Mexico (16, 17), 28C46% in Portugal (18), 5.6C7% in western Canada, 7.5C8.2% in Quebec and Ontario, 10.4C25.5% in.
