Proteases play a key role in protein digestion in ticks and other haematophagous insects. Our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. Cells of the midgut endocytose blood components. Blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. In this...

Ticks are important ectoparasites which are a considerable threat to human beings and to animals all overthe world. Enormous economic losses annually occur in livestock production around the world as a result oftheir existance. One of the ways to control ticks and tick-borne diseases is to introduce resistance to theseectoparasites through immunization. For identification of the putative protec...

Malignant theileriosis of sheep is a highly fatal, acute or subacute disease is caused by the tick-borne protozoan parasite, Theileria hirci. In this investigation ten healthy male lambs aged 5-6 months were randomly divided into two groups, A and B and were kept in isolated tick-proof pens. They were treated for internal and external parasite before commencement of the experiment. The lambs we...

Hard ticks (Acari: Ixodidae) are important obligatory blood feeding external parasites of human and animals. There have been a lot of studies on taxonomy of Iranian ixodidae. On the basis of morphological features found basically in adult male. There are problems in tick identification due to their intraspecific variations and morphological changes of the surface body of ticks after blood feedi...

Crimean-Congo Hemorrhagic Fever (CCHF) is a tick-borne viral disease that is transmitted by numerous species of ticks, which serve both as a reservoir and vector of CCHF virus (CCHFV). Molecular and serological tests were undertaken on hard ticks (Ixodidae spp.) and samples from livestock were collected in 2015 from Chabahar County in Southeast Iran. Using RT-PCR, the ticks were tested for the ...

The prevalence of Theileria spp. infection was studied in sheep in the South Khorasan province in Iran from 2003 to 2004. A total of 840 sheep from 34 flocks were clinically examined and investigated for the presence of Theileria spp. in the appropriate blood smears and any tick species on the body of the animals. In this study, 11.9% of sheep were infected with Theileria spp., with a parasitem...

BACKGROUND A survey on tick species composition was carried out in Golestan Province Iran during year 2010-2011.The aim was to determine tick species parasitizing domestic ruminants and their seasonal population dynamics. METHODS A total of 124 sheep, 92 goats, 84 cattle, 74 camels and 12 horses in several villages were inspected for tick infestation. The collected ticks preserved in 70% alco...
