Prevalence and Identification of Ixodide Ticks in Cattle in Lalo Assabi District, West Wollega Zone, West Oromia, Ethiopia

Abstract

Article InfoTicks are important parasite of cattle that cause huge economic loss at private and national level. Therefore, the cross sectional study was conducted from October 2016 to June 2017 in Lalo Assabi district of West Wollega Zone. The aims of the study were to determine the prevalence of tick infestation and to identify their predilection site, possible risk factors and distribution in the rural and urban area of Lalo Assabi districts. Peasant Associations (PAs), sex, age, body conditions of animals and ticks genera were major factors involved in the study. A systematic random sampling study design was followed to collect samples. From the total of 384 cattle, 265 (69%) cattle were found to be infested with tick. Out of five peasant associations examined, highest prevalence (80.4%) was recorded at Barko Daleti Peasant Associations. Highest prevalence (82%) was observed in male than in female animals (59%). Relatively highest prevalence was recorded in adult animals (70.7%) as compared with young and old age animals. Amblyomma, Boophilus and Rhipicephalus were tick genera with infestation rate of 30.7%, 23.2% and 15.1%, respectively. Animals with good body condition were relatively affected (74.1%). Different tick genera have different predilection sites.

Prevalence, Species Identification, and Associated Risk Factor Ixodid Tick Infestation of Cattle in Selamago District Southern Ethiopia

“…The tick species identified were the same as those reported in various parts of Ethiopia. This finding was comparable with Kebede et al, 27 who recorded a prevalence of 69% in Lalo Assabi District, West Ethiopia. Study reports of 61.98% and 61.5% prevalence were recorded in the Humbo and Hetosa districts, respectively, in the SNNPRS and Eastern Arsi zones.…”

“…As a result, economic impact of ticks and control of tick-borne diseases remain challenge for the cattle industry of the world and it is a priority for many countries in tropical and subtropical regions [7]. There are about seven genera of ticks of veterinary importance in Africa [8], out of which four genera (Amblyomma, Haemaphysalis, Hyalomma, and Rhipicephalus) are commonly found in Ethiopia [9][10][11][12][13]. In addition to this, in Ethiopia there are about 47 species of ticks infesting livestock and most of them have importance as vector and disease agent and also have damaging effect on skin and hide production [14].…”

“…Extensive survey has been also carried out on the distribution of tick species on livestock in different regions of the country in Amblyomma varigatum, Amblyomma cohaerence, Amblyomma, gemma, R. evertsi eversti, Hyalomma marginatum rufipes, Hyalomma truncatumi, Amblyommaelide, Rhipicephalus pulchellus are also frequently reported in many tick survey carried out in the different part of the country [10][11][12][13]. In Ethiopia, tick occupy the first place amongst the external parasites by the economic loss it incurred when they infest livestock particularly cattle [15].…”
