The study of prevalence and factors affecting Anaplasma maginale infection in domestic goats in Chonburi province, Thailand

Abstract

The objective of this study was to determine the prevalence and factors affecting Anaplasma marginale infection of goat farming in Chonburi province, Thailand. A total of 182 samples were collected from clinical services records from the Veterinary Teaching Hospital, Rajamangala University of Technology Tawan-ok. Moreover, the potential risk factors of A. marginale infection, including vectors infestation, barn-types, preventive medicine protocols using vector-control agents and/or deworming programs, and the farming areas were statistically analyzed. The results revealed that 24.7% of goats were positive for A. marginale infection. The Nhong Yai district had the highest infection rate at 34.1% (15/44). The Mueng, Chonburi and Sri Racha district goats were infected at the rate of 27.5% (11/40) and 24.3% (9/37), respectively. The potential significant factors affecting A. marginale infection were vectors infestation (P < 0.01) and preventive medicine protocols using vector-control agents and/or deworming programs (P < 0.05). In conclusion, the vectors infestation increases the chance of A. marginale infection. Conversely, appropriate consistent preventive medical health management by application of vector-control agents and/or deworming programs can reduce the likelihood of infection. Our study could serve as a guideline for prevention planning and for further study of livestock rearing behavior concerning infection of blood parasites in nearby areas
