Hyalomma scupense is a two-host tick infesting mainly cattle representing in North Africa the vector of tropical theileriosis (Theileria annulata infection), a major tick-borne disease affecting cattle. Any effective control programme of ticks requires a good knowledge of the biology of the target species. In the present study, three cattle farms in northeast Tunisia were surveyed during the ac...

objectives: ticks are vectors of several diseases, of which many are zoonosis transmissible to humans. the use of tephrosia leafs’ extract as a low cost acaricide is spreading among farmers in central kenya. materials and methods: the present study’s aim is to inventory endogenous control methods against dogs’ ticks among which rhipicephalus sanguineus, in the municipality of abomey-calavi. fro...

The density of spirochetes in field-collected or experimentally infected ticks is estimated mainly by assays based on microscopy. In this study, a real-time quantitative PCR (qPCR) protocol targeting the Borrelia burgdorferi-specific recA gene was adapted for use with a Lightcycler for rapid detection and quantification of the Lyme disease spirochete, B. burgdorferi, in field-collected Ixodes s...

background and aims: crimean-congo hemorrhagic fever (cchf) is a zoonosis caused by a nairovirus of the family bunyaviridae. infection is transmitted to humans mostly by hyalomma ticks. this study was conducted to determine the rate of cchfv infection in ticks in qom province of iran. materials and methods: in this study, reverse transcription – polymerase chain reaction (rt-pcr) was used to de...

BACKGROUND Mosquitoes are the primary vectors of West Nile virus (WNV). Ticks have, however, been suggested to be potential reservoirs of WNV. In order to investigate their role in the spread of the virus, ticks, which had been collected from birds migrating northwards from Africa to Europe, were analyzed for the potential presence of WNV-RNA. METHODS On the Mediterranean islands Capri and An...

BACKGROUND There is a little data on Coxiella burnetii (Q fever agent) in Iran. Ticks may play a significant role in the transmission of C. burnetii among animals. The aim of this study was to use polymerase chain reaction for the detection of C. burnetii in ticks collected in Southeast Iran. METHODS One hundred and sixty ticks were collected from domestic animals in three localities of Kerma...

BACKGROUND Borrelia burgdorferi sensu lato (s.l.) are the causative agent for Lyme borreliosis (LB), the most common tick-borne disease in the northern hemisphere. Birds are considered important in the global dispersal of ticks and tick-borne pathogens through their migration. The present study is the first description of B. burgdorferi prevalence and genotypes in Ixodes ricinus ticks feeding o...

background: the survey for the prevalence of different species of cattle hyalomma ticks was carried out in three districts (rawalpindi, multan and lahore) of punjab province in pakistan. the bionomical conditions suitable for hyalomma were also studied in laboratory. methods:  one hundred specimens of ticks of different genera were collected from each district. after identification, the hyalomm...

background: chemical control method using different acaricides as spray, dipping solution or pour-on is routinely used for controlling ticks. biological control agents are favorable due to their safety for animals and environment. entomopathogenic fungi such as beauveria bassiana are well known for controlling ticks. in this study, two iranian indigenous strains of b. bassiana ( b. bassiana 519...

Lipopolysaccharide (LPS) stimulates the innate immune response in arthropods. In tick vectors, LPS activates expression of immune genes, including those for antibacterial peptides. miRNAs are 21-24 nt non-coding small RNAs that regulate target mRNAs at the post-transcriptional level. However, our understanding of tick innate immunity is limited to a few cellular immune reactions and some charac...
