dc.description.abstract A Bayesian approach was used to evaluate four immunological assays for the clinical diagnosis of cryptosporidiosis in calves: an immunofluorescence assay (IFA), two ELISA tests and an immunochromatographic (dipstick) assay. Faecal samples from 287 calves aged less than 6 weeks with clinical signs of gastrointestinal disease were examined for the presence of Cryptosporidium spp. The high prevalence (63%) of Cryptosporidium spp. indicated the relevance of this agent in the aetiology of diarrhoea in calves. All diagnostic assays were found to be relatively specific (IFA: 94.8%; Tetra ELISA: 95.9%; Techlab ELISA: 92.7%; dipstick assay: 91.5%) and sensitive (IFA: 97.4%; Tetra ELISA: 93.6%; Techlab ELISA: 95.4%; dipstick: 87.8%). Despite a lower sensitivity, the dipstick assay provided a practical alternative to laboratory diagnosis of clinical cryptosporidiosis in calves. en_US
