Taddese A, Mustefa M, Fikru., Prevalence and
identification of camel ticks in
eastern Ethiopia, Online J Vet Res., 17 (2): 64-72, 2013. A cross
sectional study was carried out from September 2010 to March 2011 to assess the
prevalence of tick infestation and identify the species that parasitize camels
in and around Dire Dawa, Eastern Ethiopia. All
visible adult tick specimens were collected from 7 different predilection sites
on each camel. Of 384
examined animals 361(94%) were infested. A total of 11774 adult
ticks were collected, belonging to 7 different species of 4 genera identified
by stereomicroscopy. The 4 genera were Rhipicephalus, Hyalomma, Ambylomma and Boophilus. The most abundant tick species was Rhipicephalus pulchellus (46.78%),
followed by Hyalomma dromedarii
(26.85%), Ambylomma gemma (11.35%),
Hyalomma trancatum
(7.19%), Hyalomma
marginatum rufippes (3.95%),
Ambylomma variegatum
(2.59%) and Boophilus decoloratus
(1.24%). The highest infestation level of ticks was observed under the tail
(27.62%) and lowest (1.24%)
on the back or side. Infestation in male camels was 90.2% and
96.8% in females. The infestation rate varied significantly (p<0.05) between
sex groups as well as between origin of the animals. However, there was no
statistical significant difference (p>0.05) in prevalence of tick
infestation between age groups or body condition. The results clearly indicated
that tick infestations are a major problem in the study area and a programmed
tick control campaign in the region is needed.
