Abstract Cryptosporidium spp. is an important agent of neonatal diarrhoea in goat kids. Little is known about its molecular characterization in adult goats. A longitudinal study was set up to identify the species excreted by adult goats around parturition. Individual faecal samples were collected from 20 pregnant adult goats between 1 and 5 years old in one flock. Samplings began 3 weeks before the estimated kidding date and were done weekly until kidding and for 2 weeks after kidding. Cryptosporidium oocysts were concentrated from 15g of faeces using a caesium chloride (CsCl) method. Oocyst output was determined using a direct immunofluorescent antibody test (IFAT). Genomic DNA was extracted from each CsCl-concentrated faecal sample positive by IFAT and submitted to a nested PCR-RFLP on the SSU rDNA gene followed by sequencing to identify the isolates at species level. According to their kidding date, goats were sampled between 4 and 8 times. Sixteen goats, out of the eighteen which kidded, were found positive at least at one sampling date. Infection was asymptomatic. Prevalence of excretion was maximal 14 days before kidding with half of the goats excreting oocysts at this date. Excretion was higher before kidding than after kidding. Unexpected levels of excretion were observed with individual oocyst excretion ranging from 6 to 2.5×105 oocysts per gram of faeces. All isolates were identified as Cryptosporidium ubiquitum.
