Plain-English summary
A 2.5-year-old Quarterhorse stallion was found to have diarrhea and was diagnosed with cryptosporidiosis, which is an infection caused by a tiny parasite called Cryptosporidium. The diagnosis was made after tests showed the presence of cryptosporidial oocysts, which are the eggs of the parasite, and no other causes for the diarrhea were found. This case is notable because such infections are usually seen in younger or immune-compromised horses, not in healthy adult ones. The outcome of the treatment is not mentioned, so it's unclear how well the stallion responded to care.
Abstract
Cryptosporidial oocyst shedding was detected in a 2.5-year-old Quarterhorse stallion with diarrhoea. Based on the detection of cryptosporidial oocysts, and the absence of other aetiological agents or enteropathogens, cryptosporidiosis was presumptively diagnosed. This case was unusual because cryptosporidial oocyst shedding is primarily found in some immunocompromised or immature horses, and has not been reported in healthy mature horses.
