boophilus genus ticks are responsible for transferring some pathogens and reducing production factors in cattle. tropomysin (tpm) protein has actin regulator activity and playing important role in immune and allergic reactions. the main goal is to determine different aspects of phylogenetic, similarity, homology, structure and allergenicity of tpm protein. in prior study, we identified tpm by u...

Ticks harbor many pathogenic, as well as endosymbiotic and non-pathogenic agents. They are host of a variety of as yet unidentified microbes that continue to be described. In the present study, a Brucella-like bacterium was detected in a Boophilus tick by PCR amplification of a partial fragment of 16S rRNA locus followed sequencing. Our results show that the members of the genus Boophilus may a...

In recent years there has been much progress in our understanding of the phylogeny and evolution of ticks, in particular the hard ticks (Ixodidae). Indeed, a consensus about the phylogeny of the hard ticks has emerged which is quite different to the working hypothesis of 10 years ago. So that the classification reflects our knowledge of ticks, several changes to the nomenclature of ticks are im...

Free-living ixodid ticks were collected at monthly intervals from January to December 1996 by dragsampling the vegetation of Mtendere Game Ranch in the Chisamba District of the Central Province, Zambia. Ticks belonging to 11 species were recovered. Rhipicephalus appendiculatus was most abundant, comprising 90% of the total number collected. All life stages of this tick showed a definite seasona...

tick are considered as the main vector for transmission of various diseases to human being. this study was carried out to investigate the fauna of species belonging to two families of ticks, ixodidae and argasidae in west azerbaijan province, iran. a total number of 62 villages were selected randomly, from the study area 3278 ticks were collected with cluster sampling method, after collection t...

The objective of this study was to evaluate the acaricidal effect of 2 compounds extracted from Eysenhardtia polystachya in vitro, namely coatlines and matlalines. Each extract was obtained by aqueous extraction in a nitrogen atmosphere. Engorged adult females of an amitraz-resistant strain of Rhipicephalus (Boophilus) microplus were used to produce larvae and to carry out the adult immersion t...

Of all these limiting factors climate plays the most important role and determines the ecological and geographical distribution and the seasonal activities of a species (Imms, 1931; MacLeod, 1936). Within the climate complex temperature plays a fundamental role, a species being confined within a specific temperature range (Odum, 1963). An environment favourable to a given species can be determi...

The objective of this study was to determine certain aspects of the biology of Rhipicephalus (Boophilus) decoloratus larvae under laboratory and field conditions. Larvae allowed 48 h to select a vertical questing substrate preferred 90 cm rods in length to those of 60 or 30 cm, while in a separate experiment migration from rods 5 cm or 25 cm in length to rods 45 cm in length continued between 4...

The cattle tick Rhipicephalus (Boophilus) microplus has recently invaded West Africa and caused anxiety amongst farmers in Ivory Coast, as livestock production was severely affected. The introduction of this tick species has remained unnoticed for several years, as all the members of this genus are very similar in appearance. To overcome the cumbersome morphological identification of the four c...

Ticks were collected at approximately bi-monthly intervals between June 1996 and June 1997 from crested francolins, Francolinus sephaena, and from the vegetation on a mixed cattle and wildlife farm in Limpopo Province, South Africa. The birds were infested with the immature stages of 13 tick species, of which Amblyomma hebraeum, Amblyomma marmoreum and Hyalomma marginatum rufipes were the most ...
