Identification and prevalence of ixodid ticks of cattle in case of Aleltu district, Oromia regional state, northern Ethiopia

Abstract

AbstractBackgroundIn Ethiopia, ticks are the major threat to cattle productivity and production, leading to considerable economic losses. The current study was designed to estimate the prevalence of ixodid tick infestation, identify species, assess major risk factors associated with tick infestation and assess public awareness.MethodsA cross‐sectional and questionnaire‐based study was conducted from January 2022 to June 2022 in the Aleltu district. The study animals were selected using a simple random sampling method.ResultsOf the 400 cattle examined, 303 (75.8%) were found to be infested by one or more tick species. Six species of ticks were identified that belonged to three genera: Amblyomma, Hyalomma and Rhipicephalus, and the subgenus Rhipicephalus (Boophilus). The most common tick species identified in terms of their prevalence and dominance were Rh. (Bo) decoloratus, Rh. evertsi, Am. variegatum, Hy. rufipes, Rh. bergeoni and Rh. praetextatus. In the present study, Rh. (Bo) decoloratus was the most prevalent (56.8%) in the study area. Among the risk factors considered, the prevalence of tick species had a statistically significant (p < 0.05) association with the age, production systems and body condition of animals. Out of 110 people interviewed, 107 (97.3%) believed there was a tick infestation in their village, and almost all farmers 103(93.6%) in the study area were unaware that ticks serve as vectors.ConclusionsThe present study provides preliminary information on the prevalence of tick infestation and the composition of ticks in the Aleltu district. Ticks are a major problem for the cattle in the study area. Therefore, the problem observed in the study area alarms the district and calls for a comprehensive control strategy.
