background: studies concerning ticks were of interest to evaluate the distribution and composition of species affecting live stock, thus it was a main step in our knowledge of the pathogens that they may transmit by tick. methods: a collection of 21 adult female and 15 male hard ticks, all is representing a single species of tick collected under the tail of wild goat. the specimens preserved in...

background : boophilus annulatus is an obligate blood feeder tick that can cause great losses in animals due to anemia and its ability to injure its host skin directly. the aim of this study was identification of cattle humoral immune response to some tick proteins during experimental infestation. methods : immune sera against tick were collected from experimentally infested cattle with ticks. ...

BACKGROUND:Ticks are obligatory blood sucking arthropodsthat can transmit important pathogens. OBJECTIVES: Thedistribution and diversity of ticks fauna were last studied in the northof Iran in 2007. Mazandaran province has a humid climate, whichis favourable to animal husbandry such as sheep breeding. Due tohumid climate, the likelihood of exposure to tick infestation isincreasing. The aim of t...

A portion of mitochondrial 12S rDNA sequences (337-355 base pairs) and 63 morphological characters of 36 hard-tick species belonging to 7 genera were analyzed to determine the phylogenetic relationships among groups and species of Rhipicephalus and between the genera Rhipicephalus and Boophilus. Molecular and morphological data sets were first examined separately. The molecular data were analyz...

The efficacy of pour-on formulations of three macrocyclic lactone endectocides (moxidectin, ivermectin, and eprinomectin) was evaluated on cattle against Boophilus microplus (Canestrini) using two different treatment regimes. A single application treatment regime with each endectocide showed that fewer ticks per calf were recovered from all treated calves than from untreated cattle, but the lev...

To evaluate the prevalence of infestation of ectoparasites of horses, a total of 894 horses (367 males and 527 females), aged 1-7 years old were examined. Horses were groomed for collection of ectoparasites. Out of the horses examined, 164 came from Fundong, 80 from Acha, 30 from Fongo-Tongo, 30 from Fokoue and 17 from Dschang, all of which were infested with ectoparasites. Five hundred and sev...

background: traditionally, morphological features of rhipicephalus (boophilus) annulatus from closely-related ticks have been considered for their identification and differentiation. however, it is difficult and requires expertise in order to accurately identify and differentiate engorged female ticks and some developmental stages such as larva and nymph from other similar ticks. hence, molecul...

Engorged females of Boophilus microplus, stored at 4 degrees C for up to 5 days, and females, kept at room temperature for 1 day and then at 4 degrees C for 1 day, showed no significant differences in their response to an organophosphate as determined by the Drummond adult test.

A sonication method for the homogeneous extraction of acetylcholinesterase (AChE) from the synganglia of adult ticks is described. The method provides for the extraction of sufficient AChE for multiple assays of enzyme activity in the presence of specific organophosphate (OP) inhibitors for the rapid diagnosis of OP-insensitivity and assignment of homozygous susceptible (SS), heterozygous resis...

Only a small number of tick species are vectors of important economic diseases or toxicosis in sub-Saharan Africa (see Table 1). These are Amblyomma hebraeum, Amblyomma variegatum, Hyalomma dromedarii, Hyalomma truncatum, Ixodes rubicundus, Rhipicephalus (Boophilus) microplus, Rhipicephalus (Boophilus) decoloratus, Rhipicephalus appendiculatus, Rhipicephalus evertsi evertsi, Rhipicephalus zambe...
