Investigating the dependence of Babzia blood parasite prevalence in sheep of Andimshek city in spring and summer, on sex, age and season.

Babesia is also one of the parasites that cause major losses in the animal husbandry industry. Identifying the animals carrying Babesia is importance in controlling and preventing the disease. Microscopic observation of the protozoan parasite in the stained blood in the acute form and serological tests is helpful, but most Babesia species cannot be differentiated, and false positive and negative results are generally observed in these tests. Our purpuse was to Assessment the prevalence of Babesia parasite in Andimshek city sheep during spring and summer of 2022 and gender and age effects on it, using the molecular method of polymerase chain reactionIn the spring and summer of 2022, 100 females and 100 male apparently healthy sheep from different areas of Andimshek city were completely randomly blood sampled and sent to the laboratory. After extracting DNA from blood, polymerase chain reaction and electrophoresis was performed. Data were statistically analyzed using spss software and T-test statistical method and mean and standard deviation were calculated. The prevalence of Babesia blood parasite in the female sheeps were higher than males. Also prevalence of this blood parasite in sheep over 2 year’s old was higher than under 2 years. But the prevalence rate in males and females in different ages and different months of spring and summer was not significant. The results showed that the prevalence of Babesia blood parasite in Andimeshk city sheeps in spring and summer does not depend on sex, age and season.
