Cryptosporidium parvum: prevalencia y factores de riesgo en becerros del municipio de Cuajinicuilapa, Guerrero, México

Abstract

ABSTRACT: Cryptosporidium parvum is coccidia, which is the cause agent of diarrheic diseases in several vertebrate species, from new born up to three months old calves. Samples were taken to a total of 381 calves from 54 double purpose production cattle farms from the Municipality of Cuajinicuilapa, in the Costa Chica Region of the Guerrero State in México. Fecal samples were colected in plastic bags directly from the rectum. The serial microscopical examination of aeces was carried out using Faust’s technique and the immunofluorescence technique using the  Meridian, Bioscience, Inc. diagnostic kit (Cincinnati, Ohio) which is specific for Cryptosporidium spp. y Giardia spp. The highest prevalence found was 3.14% corresponding to two month old calves. The zootechnic variable such as the type ofexplotation, speciphycally the double purpose production system, was the highest risk factor (OR 8.2, IC 95%0.922–72.90) maybe because of the type of management that is carried out on the animals in the different cattle farms. Another relevant zootechnic variable, considered a risk factor is that of not cleaning the udder before feeding the calves (OR 3.72, IC 95% 0.250–55.64) . It can therefore, be concluded that control measurements based on cattle handling techniques, minimize the degree of exposure to the parasite and, in this way, morbidity can also be significantly reduced.
