Four acaricides (amitraz, cyfluthrin, permethrin, and pyrethrins) were studied for their efficacy in the rapid killing of Amblyomma americanum, A. cajennense, and A. maculatum (Acari: Ixodidae) and eight acaricides (amitraz, carbaryl, chlorpyrifos, cyfluthrin, fipronil, permethrin, pyrethrins, and selamectin) for their efficacy in the rapid killing of Rhipicephalus sanguineus (Acari: Ixodidae)....

The present study describes a case of leg lymphedema due to iliopectineal bursitis associated with rheumatoid arthritis (RA), which was satisfactorily controlled by surgery and combination therapy with methotrexate (MTX) and tacrolimus. A 68-year-old male, who had a six-year history of RA, developed an iliopectineal bursa associated with destruction of the hip joint. The mass gradually increase...

Coronado A. 2006. Ixodiphagus hookeri Howard, 1907 (Hymenoptera: Encyrtidae) in the brown dog tick Rhipicephalus sanguineus Latreille, 1806 (Acari: Ixodidae) in Venezuela. Entomotropica 21(1):61-64. Nymphs of the ixodid tick Rhipicephalus sanguineus were found naturally infected by the tiny wasp Ixodiphagus hookeri. The parasitism resulted in the death of the host ticks, as cause of ingestion o...

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...

Five adult female goats were brought to our veterinary hospital with infertility. Ultrasonography showed what seemed to be hydrometra or cystic lesion in the genital region of 18-month-old twin local breed female goats. After slaughter of the does and excision of the genital tract, a macroscopic examination revealed bilateral hydrosalpinx and extreme dilation of the ovarian bursa with complete ...

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 ...

A total of 100, day-old broiler chicks were randomly divided into 5 equal groups and kept under elevated temperature (93-97F) to see the effect of ascorbic acid and acetylsalicylic acid on the feed conversion ratio (FCR), immune status and ratio of weight of bursa, thymus and spleen to body weight. Heat stress increased the FCR but decreased the immune response and ratio of bursa, thymus and sp...

Seventy-three nyalas (Tragelaphus angasii) in the Umfolozi, Mkuzi and Ndumu Game Reserves in northeastern KwaZulu-Natal were examined for arthropod parasites during 1983 and 1984. In addition, six animals were examined during 1994. Ten ixodid tick species, two louse species and a louse fly species were recovered. The nyalas were good hosts of all stages of development of Boophilus decoloratus, ...

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...
