“…In one study in Balochestan province (South-East Iran), 51% of H. a. excavatum and 1.3% of H. a. asiaticum were infected with sporozoites of T. annulata recorded from 510 tick salivary glands examined with methyl green/pyronin staining (Razmi et al 2003). However, our results indicated that H. a. anatolicum was the major tick vector of T. annulata in West and North-West Iran.…”

The presence of potential vectors, ticks, and susceptible hosts of bovine malignant theileriosis in all parts of Iran pose a real threat to food animal industry. The present study was conducted to determine the infection rate of ticks collected from naturally occurring bovine theileriosis in West and North-West Iran. Two hundred and thirty seven cattle suspected of suffering from theileriosis were investigated for the presence of Theileria annulata in the blood smears and any tick species on their body. In this study, 402 ticks were obtained from 99 cattle. The examination of 402 ticks by polymerase chain reaction (PCR) using primers derived from the gene encoding heat shock protein70 (Hsp70) revealed that 39.9% of Hyalomma anatolicum anatolicum, 3.5% of H. asiaticum asiaticum, and 18.2% H. anatolicum excavatum, were infected with T. annulata. The results suggest that H. a. anatolicum may play a major role in transmission of T. annulata infection in Iran. Finally, digestion of the PCR products of T. annulata with two different restriction enzymes produced only a single pattern.

“…Mazlum (1971) had revealed that most areas for distribution of R. bursa were in the northern areas of Iran and R. sanguineus was mainly found in the south-west. Razmi et al (2002Razmi et al ( , 2003 cited two reasons for this difference. First, cattle, in contrast to sheep, are an unsuitable host for R. sanguineus.…”

“…First, cattle, in contrast to sheep, are an unsuitable host for R. sanguineus. Second, changes in weather conditions that occurred after a long stable period have changed the dispersal and richness of ticks and caused a rapid spread of strongly adaptable ticks, such as R. sanguineus (Razmi et al 2002(Razmi et al , 2003. The patterns and occurrence of ticks in different anthroponized zones and biotopes were not the same.…”

This report presents the results of the first faunistic study of hard ticks in Qazvin province of Iran. The primary objective was to determine the species diversity and geographic distribution of hard ticks that parasitize domestic ruminants. Information about the abiotic preferences of these species has been provided. A total of 286 cattle, 1,053 goats, and 2,050 sheep were examined in 13 villages in 28 flocks distributed throughout the studied areas. Total direct body collections of ticks were made from each domestic ruminant. A total of 228 Ixodid specimens belonging to nine species in three different genera were recorded in the areas, including Boophilus annulatus (Say, 1821), Hyalomma anatolicum Koch, 1844, Hyalomma asiaticum (Schulze and Schlettke, 1929), Hyalomma detritum Schulze, 1919, Hyalomma dromedarii Koch, 1844, Hyalomma marginatum Koch 1844, Hyalomma schulzei Olenev, 1931, Rhipicephalus bursa Canestrini and Fanz, 1878 and Rhipicephalus sanguineus (Latreille, 1806). The most abundant species on sheep was R. sanguineus (46.92%), while B. annulatus (6.6%) found only on cattle. A finding of great significance was that R. sanguineus, the main vector of babesiosis, is firmly established throughout the counties. A further objective of the study was to compare the abundance of the major tick species on domestic ruminants. This was carried out at 19 sampling sites. The highest number of ticks was collected in July-August during the hot season.

“…The blood and lymph node smears together with systemic blood samples were collected during the study. The smears were fixed via pure methanol for 1 min and stained with Giemsa method, and parasitemia was determined by counting the number of parasites in 100 different microscopic fields via a light microscope at ×1000 magnification (Razmi et al, 2003). After forming the clot, the blood samples were centrifuged at 1800g rpm for 10 min, and the serum sample was isolated and kept at −80 • C until the experiment was performed.…”
