Re-emergence of Chorioptes bovis (Acari: Psoroptidae) in cattle in the state of Rio Grande do Sul, Brazil

Abstract: Here we describe an outbreak of chorioptic mange in cattle, 56 years after its first identification in Brazil. Between the months of June and July 2011, dermatitis characterized by alopecia and crusted and thickened skin at the insertion of the tail and in the ischiorectal fossa was recognized in 40 (35.7%) out of 112 Holstein cows on a farm in the northeastern mesoregion of the state of Rio Grande do Sul, Brazil. After diagnosing mange caused by Chorioptes bovis, the cows were weighed and treated with 0.5% iv… Show more

“…In this case, the use of Amitraz bath was able to successfully resolve the mange infestation in the goat (Brugger and Braun, 2000). The success achieved with the bath is because it was applied topically and Chorioptes mites are non-burrowing and surface living mites (Vieira et al, 2014). Amitraz generally has the ability to wash off scabs when applied topically as in this case, it washed off the layers of crusts and scabs which gave protection to the mites, thereby exposing the mites to the effects of Amitraz and their subsequent eradication.…”

“…До цієї групи відносять збудників акарозів, зокрема нашкірних кліщів роду Chorioptes, які у великої рогатої худоби призводять до захворювання на хоріоптоз. Інвазія спричиняє виникнення запальних процесів у шкірі, супроводжується занепокоєнням, свербежем, випадінням волосся і, як наслідок, втратою м'ясної та молочної продуктивності у великої рогатої худоби [5][6][7][8][9][10].…”

“…Про значне поширення хоріоптозу великої рогатої худоби на території Бразилії свідчать науковці, які у 35,7 % корів при дослідженні зіскобів зі шкіри виявили кліщів Ch. bovis (Vieira et al, 2014). В Ізраїлі науковці встановили, що показники екстенсивності хоріоптозної інвазії у великої рогатої худоби становили 80,5 %.…”
