| Parasitic infections, especially helminthes infections of the gastrointestinal tract due to the latent symptoms play a very important role in the growth and efficiency of ruminants.The current research was performed to determine the prevalence of haemonchosis in goats and effect of some risk factors such as age, sex, and months on the infection rate. Also, our study includes investigate the hematological and biochemical changes in the haemonchosis-infected goat, then, utilized the PCR technique to confirm the H. contortus diagnosis in goats. The result of epidemiological study revealed that only 73 out of 693 examined goats were positive to infect with Haemonchus spp. at infection rate of (10.53%). The incidence of Haemonchosis was related to climatic conditions, with the highest (23.07 %) and lowest (4.34 %) percentages occurring in October and June, respectively. Furthermore, the highest (14.01 %) and lowest (4.76 %) infection percentages were recorded in goats aged > 5 years and 9 months to 2 years old, respectively. According to sex, infection percentages were (14.24%) and (7.02 %) for female and male respectively.Hematological and biochemical parameters results revealed that infected goats suffering from gradual decline in Hb concentration, pocket cell volume, total erythrocyte count, total leucocyte count, lymphocyte, neutrophil, total serum protein and albumin, while, eosinophil count was increased significantly. Also, serum enzymes ALP, ALT, and AST showed significant increases in infected goats. The result of PCR were showed that specific primers (HcI-F, HcI-R ) were successfully for amplifying the ITS-2 rDNA gene with 295bp -long fragment to H. controtus.Due to the effect of age, sex and season on H. contortusinfection, it is very important to have control and prevention programs and treatment schedule in the herd. | ||
