Prevalence of tick infestation in dromedary camels (Camelus dromedarius) brought for slaughter in Mashhad abattoir, Iran.
This study was carried out to investigate the prevalence of tick infestation and identify tick species that parasitize dromedary camels. Since April 2012 through March 2013, a total of 400 camels that brought for slaughter in Mashhad abattoir were examined for tick infestation. Out of the total 400 camels examined, 237 were infested and annual prevalence of tick infestation 59.25 % (95 % CI 54-64) was calculated. The higher prevalence rates were found in the summer and spring, especially the summer that prevalence rate was the highest. A total of 1,122 ticks were collected from the infested camels and identified by stereomicroscopy. Hyalomma dromedarii was the predominant tick species and comprised 70.76 % of the collected ticks. The frequency of other species was as follows: H. excavatum (19.25 %), H. anatolicum (4.81 %), H. asiaticum (4.72 %), Rhipicephalus turanicus (0.17 %), H. detritum (0.09 %), H. impeltatum (0.09 %) and H. schulzei (0.09 %). Based on the results of present study, it is concluded that camels mostly harbor Hyalomma spp. The species of this genus are the most notorious ticks for transmission of human and animal diseases. Therefore, appropriate tick control measures need to be employed and pour-on method for acaricide application is suggested because this method is fast, easy and suitable for use by camel owners in deserts.
