“…Several studies have been done to investigate the epidemiology of Theileriosis and Babesiosis in Iran. Razmi et al (2003) reported 26.1 % of sheep and 14.8 % of goats were infected with Babesia in Mashhad. Serological study of Babesiosis indicated a seroprevalence of 47.5 % in Khuzestan province (Hashemzadeh et al 2006).…”

“…In study of ovine theileriosis in Oman, Shayan et al (2011) reported that they were not able to diagnose parasite with microscopic examination, but they identified T. ovis and T. lestoquardi with PCR method. Razmi et al (2003); Schnittger et al (2004); Altay et al (2005) and Aktas et al (2005) believed that for diagnosis of Theileria and Babesia species, more accurate and sensitive methods than microscopic examination of stained blood smear, like PCR method is required. However, the PCR method enables us to detect clinical, subclinical and chronic infections .In this study which conducted on sheep in Zabol, by microscopic examination 8 cases (10 %) were positive where 6 samples were infected with Theileria and 2 samples with Babesia and by PCR method, the prevalence of infection with Theileria was 66.25 % (53 samples) and Babesia 3.75 % (3 samples).…”

“…These methods don't have specificity and have cross reaction with other piroplasm species; In addition, false positive and negative results are also commonly observed. Molecular methods are sensitive, specific, and rapid for diagnosis of Babesia and Theileria and provide more accurate information for future investigation (Uilenberg 2006; Razmi et al 2003;Schnittger et al 2004;Altay et al 2005).According to clinical and morphological observations, Livestock in Zabol are determined to have these disease causing great damages to the economy and production in this area. Regarding the importance of pathogenic protozoa, Babesia and Theileria, wide geographical distribution in Iran and few studies on their prevalence, especially Babesia, in livestock in Zabol, the accurate detection of these protozoa is a certain necessity to improve control measures.…”

A study on prevalence and identification of Ovine Theileria and Babesia infection in Zabol using PCR method

Infection with Babesia and Theileria Causes high mortality and economical losses in livestock and has a relatively high prevalence in Iran. In Zabol, animals are susceptible to this disease because of presence of vector ticks, weather conditions and smuggle animal across the border and they cause great damages to the economy and production. However, few studies have been done for differentiation of Theileria and Babesia in sheep in this area. The purpose of the present study was to determine the prevalence of Babesiosis and Theileriosis in sheep in Zabol. A number of 80 animals were randomly selected and their blood samples were examined. The presence of Theileria and Babesia parasites in each sample was determined with PCR and microscopic examination. Of 80 blood samples obtained from sheep, 8 cases (10 %) were positive by microscopic examination where 6 samples were infected with Theileria and 2 samples with Babesia. The result of PCR method determined the prevalence of 66.25 % (53 samples) and 3.75 % (3 samples) for Theileria and Babesia, respectively. The correlation between these two methods (PCR and microscopic examination) was determined with Kappa statistical test. Based on the obtained results, it is concluded that Babesiosis has a low prevalence among the sheep of Zabol. This is the first report in which ovine Babesiosis has been studied in this region using molecular identification techniques.

This study aimed to assess lipid peroxidation and antioxidant enzymes in goats naturally infected with Babesia ovis. Red blood cell count (RBC), hemoglobin (Hb) concentration, packed cell volume (PCV), malondialdehyde (MDA) concentration, erythrocyte superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) activities and total antioxidant capacity (TAC) were determined in 15 goats naturally infected with B. ovis as well as same number of healthy goats. The parasitological diagnosis was confirmed using polymerase chain reaction (PCR) analysis by amplifying a partial 18S rRNA gene sequence of B. ovis. Percentage of parasitemia varied from 0.01 to 1%. The activities of erythrocyte GSH-Px, SOD, CAT and TAC were significantly lower (p<0.05) in the infected goats than in healthy ones. MDA concentration in erythrocytes of infected goats was significantly higher in infected goats than in healthy ones (p<0.05). Severity of parasitemia showed a positive correlation with the MDA and negative correlation with PCV, SOD, CAT, GSH-Px and TAC. Also, MDA was negatively correlated with PCV, SOD, CAT, GSH-Px and TAC. The results of this study suggested that oxidative damage to RBCs may contribute to the pathogenesis of anemia in caprine babesiosis.
