ABSTRACT
To establish the association between sheep farm management practices and cryptosporidiosis in Central Mexico, 37 farms were invited and questionnaires answered by owners. Faeces samples were taken from lambs under 3 months old and ewes in the farms. Parasites were identified by modified Ziehl-Neelsen stain. Questionnaire included: general farm information, facilities characteristics, facilities cleaning measures, water use and farm and animal management practices. Farms were grouped in a low ( Pound 3,37%), medium (3.38-49.9%) and high basis ((3)50%) according to prevalence. Associations (OR) were calculated according to positivity, compared by chi-square test. A general prevalence of 34,33% was found. Five variables showed statistical significance (p<0.05). Associations found were: use of bed, grazing place, and bottle cleaning. The only association found between management practices and cryptosporidiosis that could represent a risk was the grazing place. This report is the first one in the country regarding predisposing conditions for cryptosporidiosis.

To determine Cryptosporidium spp. prevalence in faeces from asymptomatic sheep, 37 family flocks in Mexico State were sampled. Data were collected by the interview method and Ziehl-Neelsen stain of faecal samples for Cryptosporidium identification. The independent group proportion hypothesis test was used for differences in prevalences between sheep farms. A 34.3% general prevalence was found, and prevalence in herds with >100 animals was significantly higher (40.6%). Correlation was found between flock size and Cryptosporidium spp. presence (odds ratio, OR, 2.57; confidence interval, IC(95%), 1.84-3.60).
