The efficacy of an amitraz/cypermethrin pour-on preparation (1% w/v each) was tested against natural tick infestations of buffaloes, eland and blesbok in three separate trials. The eland were also treated with a 0.02% abamectin (w/v) acaricidal pour-on preparation. The amitraz/cypermethrin pour-on was effective against Amblyomma hebraeum, Rhipicephalus evertsi evertsi, Rhipicephalus appendicula...

Continuous cell lines derived from many of the vectors of tick-borne arboviruses of medical and veterinary importance are now available. Their role as tools in arbovirus research to date is reviewed and their potential application in studies of tick cell responses to virus infection is explored, by comparison with recent progress in understanding mosquito immunity to arbovirus infection. A prel...

background: considering the importance of ticks as a main group transmitting pathogen organisms, this study de­signed to recognize immunogenic proteins in different tissues of rhipicephalus ( boophilus ) annulatus tick and to find out if there are common proteins in these tissues. methods: seven cattle were experimentally infested with about 10000 r. annulatus larvae and their humoral im­mune r...

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...

overall 1906 adult ticks, as well as their nymphs and larvae were collected from the body surface of cattle in the animal husbandries located in north, north-east, south and south-west of ahwaz area, khoozestan, iran, during 1991-1993. the identified adult ticks were hyalomma anatolicum anatolicum (c.l.koch, 1844), hyalomma anatolicum excavatum (c.l. koch, 1844), boophilus annulatus (say, 1821)...

This study aimed to investigate the frequency of homologous antibodies of IgG class against Borrelia burgdorferi in buffaloes in the state of Pará, Brazil. Blood serum samples from 491 buffaloes were analyzed by means of the indirect ELISA test, using crude antigen produced from a cultivar of the North American strain G39/40 of B. burgdorferi. There were 412 positive samples (83.91%), and there...

Babesia bigemina was retained in the vector Boophilus decoloratus for a complete generation despite the use of the babesicide, imidocarp dipropionate, to prevent reinfection. This drug did not sterilize ticks of the B. bigemina infection as has been suggested for B. bovis.
