ABSTRACT
<p><b>OBJECTIVE</b>To survey the prevalence of cattle ticks in Nur County and prepare a list of tick fauna in this district.</p><p><b>METHODS</b>This investigation was carried out on 150 head of cattle ticks of rural areas of Nur city which is located in Mazandaran province during spring and summer seasons of 2011. The collected ticks were identified using light microscope and available systematic keys.</p><p><b>RESULTS</b>A total number of 1 563 ticks were isolated from examined cattle and their genus and numbers including: Ixodes ricinus 51% (111 male and 691 female) and Boophilus annulatus 49% (83 male and 678 female), respectively.</p><p><b>CONCLUSIONS</b>Results of the current investigation indicate the presence of two species of acarine ectoparasites which have potential health risk Ixodes ricinus and Boophilus annulatus. More studies are required to increase our data concerning ticks and other ectopreasites of ruminants in other areas of Mazandaran province and should be noted to their ability in transmission of infectious agents.</p>
ABSTRACT
Objective: To determine the presence of Trypanosoma evansi (T. evansi) and the effect of trypanosomosis on hemato-biochemical profile of dromedary camels in Semnan, Iran, which has not been reported yet. Methods: To perform this project, blood samples were collected by venipuncture into plain and EDTA-K2-containing vacutainer tubes from 21 dromedary camels (12 males and 9 females) aged 3-18 years, from 4 different regions of Semnan. Results: Microscopic examination of stained thin blood smears revealed the presence of T. evansi in one of the samples. However, it should be noted that this sample showed a very high parasitemia (more than 5 trypomastigote were visible per microscopic field with MGG, 1 000×). This heavy parasitemia was associated with an 18-year-old female camel that showed symptoms of corneal opacity, intense emaciation and pale mucous membranes. Comparison of hematologyical and serum biochemical profiles between the camel infected by T. evansi and uninfected camels indicated anemia, leukocytosis, hyperproteinemia, hypoalbuminemia, hyperglobulinemia, reduction A/G ratio, increased α
