Abstract
Ectoparasites (insect and arachnids) are a
worldwide problem, which are responsible for up to 80% losses to the livestock
economy. Among these, the Ixodids (hard ticks) are the most important and also
transmit diseases like babesiosis, theileriosis and anaplasmosis. The present study was aimed to identify prevalence and
distribution of the hard tick species using morphological and molecular keys in
large ruminants of Pothohar region of Pakistan. Morphological investigations of
ticks from 967 cattle and 665 buffaloes revealed the genera (3) and species (13)
of various Ixodid ticks mainly Rhipicephalus (R), Hyalomma (Hy), and Dermacentor (D)
comprisedof R. microplus, R. annulatus, R. australis, R. eversti, R.
turanicus, R. decloratus, Hy. dromedarii, Hy. scupens, Hy. rufipes, Hy.
truncatum, Hy. excavatum, Hy. detritum and D. atrosignatus. Tick
invasion was statistically higher in cattle (53.48%) than buffaloes (40.70%).
Among these 10 species identifications were confirmed through morphological
identification, however, molecular characterization of tick analysis (using
partial ITS2 gene) confirmed
prevalence of R. microplus, Hy. detritum and D. atrosignatus.This study provides the basic genetic identification tool for investigating
the tick species and their phylogenetic relationship in tick species commonly
found in humans and animals. The precise identification unquestionably can play
a dynamic role in employment of appropriate control measurements, as different
genera/species cause different diseases in livestock. Different tick species
identified on the basis of morphological features and molecular
characterization, will add value to the existing knowledge in identification of
ticks in the Pakistan, as well as helpful in
various disease diagnosis spread due to these hard tick species.
