Molecular Identification And Treatment Of Theileriosis In Small Ruminants Of Northern Balochistan

by Mir Ahmad Khan (2005-VA-214) | Prof. Dr. Muhammad Arif Khan | Prof. Dr. Muhammad Azam Kakar | Prof. Dr. Muhammad Sarwar Khan | Prof. Dr. Aftab Ahmad Anjum.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: The present study was conducted to investigate the prevalence of Ovine and Caprine Theileriosis in Northern Highlands and Suleiman Mountain Region of Balochistan, Six thickly populated /union councils were included in the study area. Samples were collected from 2870 animals Sheep (n= 2200) and Goats (n= 670) for screening of the disease. The samples were collected and processed in Regional Disease Investigation Laboratories, Department of Livestock and Dairy Development Balochistan, T.B. Sanatorium Hospital Quetta and Center for Vaccinology, Bacteriology, The University of Balochistan, Quetta and Medicine Laboratory, Department of Clinical Medicine and Surgery, The University of Veterinary and Animal Sciences, Lahore. Data revealed 20.82% disease in sheep and 9.70%. in goats. The regional prevalence of theileriosis revealed 19.19% in Northern Highlands and 17.48% in Suleiman Mountain Region Chi-square analysis showed significant difference in the prevalence of disease in sheep and goats. The regional difference was not significantly different between two regions of Northern Balochistan. The comparison among union councils showed significant difference being highest prevalence (22.71%) in union council Kuchlak district Quetta followed by Aghberg (18.42%) and Hanna Urak (15.53%) in Northern highlands and Union Council Zangiwal Jogezai (19.83%) followed by Kach Amaqzai (16.30%) and Sinjavi (15.92%) in SMR. The disease prevalence when compared among 4 different breeds of sheep showed significant difference being highest in Karakul breed (34.62%) followed by Shinwari (24.54%), Bibrik (19.36%) and Harnai (16.40%). The highest prevalence of theileriosis in sheep and goats were observed in Summer season (30.30%) followed by Autumn 19.07%, Spring 14.52% and Winter SUMMERY 105 7.61%. Chi-square analysis of the data showed significant difference in the prevalence of the disease in different seasons of the year. The disease was also compared in three age groups of sheep and goats. The data showed 22.17% disease in adult animal group above 2 years of age followed by 15.85% in animals between 1-2 year and 7.99% in age group below one year. Statistically significant difference in all age groups was found in chi-square analysis. The sex wise prevalence of theileriosis revealed non-significant difference between male and female sheep and goats. Two different species of Theileria were reported by many researchers causing disease in sheep and goats. The PCR was carried out for the identification of Theileria species affecting sheep and goats in Balochistan. Two species specific sets of primers were designed using 18SRNA gene sequence to identify these two species of Theileria and the distribution among the two species of animals. The genomic DNA of two species of parasite was successfully amplified in positive samples. The assay was proved successful and we recommend for the prevalence surveys for theileriosis in sheep and goats. The data showed that the prevalence of T. lestoquardi was 73.80% in sheep and 69.23% was in goats in the target regions. It was found the T. lestoquardi was highly prevalent and causing theileriosis in small ruminants. The prevalence of T. ovis was 26.19% in sheep and 30.76% in goats respectively in the investigated animals; it was less than T. lestoquardi. It was concluded that both Theileria species were identified and found circulating in small ruminants in the target region of Balochistan. In the study we determined that PCR method based on 18S RNA gene could detect and differentiate T. ovis and T. lestoquardi. Effect of theileriosis in sheep and goats on hemeto-biochemical parameters were studied included RBCs, Hb%, PCV, Platelets, WBCs, MCV, MCHC, AST, ALT, BUN, Bilirubin and Creatinine. Blood samples were collected from Theileria confirmed, diseased animals (sheep and SUMMERY 106 goats) along with equal number of healthy animals for comparison. In sheep RBCs, Hb%, PCV, WBCs, MCHC, AST, ALT and Creatinine values showed significant difference when compared with values of healthy animals. Significant (p<0.05) reduction was noted in measurement of RBCs, Hb%, PCV and MCHC whereas, AST, ALT and Creatinine showed significant increase in diseased animals. In goats affected with theileriosis showed significant decrease in RBCs count and Hb%. The values for AST, ALT and Creatinine were found significantly increased in diseased animals when compared with healthy control group of equal number of animals. In present study it was noted that Butalex intra muscularly at the rate of 2.5 mg/kg body weight is quite effective in eliminating the Theileria parasite from the blood of sheep and goats and treatment at the day 10 post treatment. Imizol was also found an effective treatment of theileriosis but less effective than Butalex. Availability: Items available for loan: UVAS Library [Call number: 2690-T] (1).
