A research project was carried out to determine the prevalence of gastrointestinal and haemoparasites and the seasonal fluctuations in camel slaughtered in abattoir of Mashhad in Khorasan Razavi province. A total of 306 dromedaries (Camelus dromedarius) in Mashhad abattoir were examined between October 2008 and April 2010 .By coproscopy examinations 75.1% and 18.62% dromedaries were found to be harboring different types of nematod eggs and Eimeria oocyst ,respectively. Faecal flotation revealed the presence of Nematodirus, strongyloides, Trishuris, Marshallagia, stongyle type nematode eggs, Eimeria dromedari and E.cameli. Moreover, 1.6% of dromedaries were infected with Cryptosporidium spp. by modified ziel- nelson method. A total of 262 dromedaries14 (5.34%), 1 (0.58%) dromedaries were infected with Dipetalonema evansi and Trypanosoma evansi, respectively. In this study we didn’t find any infection with Theileria and Anaplasma. Prevalence rate of infection with Dipetalonema was highest on autumn, 4-8 year and female. In a second study, inspection of testis, epididymises and spermatic cord of 172 camels 10(5.81%) were infected with adult forms of Dipetalonema evansi. In addition, gastrointestinal tracts of 50 camels slaughtered in Mashhad abattoir were used for identification and count of helminths. Postmortem examinations revealed that the most prevalent of helminths were Trichostrongylus probolurus (64%) , Trichuris globulosa (40%). Nematodirella dromedarii, Trichostrongylus probolurus, Trichostrongylus colubriformis, Cooperia oncophora, Nematodirus oiratianus, was identified from dromedary for the first time in Iran. The prevalence observed in the present study indicates the necessity of using aniparasitic drug for increasing health and productivity of camels.
