Seroprevalence and Risk Factors of Anaplasma marginale in Water Buffaloes in Nile Delta of Egypt
Purpose
Bovine anaplasmosis is a major tick-borne disease in ruminants, resulting in significant economic loss for the dairy sector. This study aimed to evaluate the seroprevalence of Anaplasma marginale (A. marginale) in buffaloes in three governorates in Nile Delta of Egypt.
Method
A total of 400 serum samples from water buffaloes were examined using commercial cELISA kit.
Results
The overall seroprevalence of A. marginale was 12.5% and Kafr ElSheikh governorate has the highest seroprevalence rate (15.28%). The seroprevalence was higher in females (13.33%) than males with non-significant difference. Moreover, adult animals older than 8 years exhibited a significant risk for A. marginale seropositivity (22.92%), particularly during the summer (22.52%) and autumn (13.73%). Significant differences (P < 0.05) in seroprevalence rates were observed between tick-infested animals (14.96%) and those not treated with acaricides (17.7%), highlighting the influence of tick infestation and lack of acaricidal intervention on infection rates.
Conclusion
The present study revealed the existence of antibodies against A. marginale in water buffaloes reared in Nile Delta of Egypt. Thus, the proper policies and control program should be adopted to reduce spreading of infection.
期刊介绍：
Acta Parasitologica is an international journal covering the latest advances in the subject.
Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews.
The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
