A new avian Cryptosporidium genotype in a 1-month-old caged brown wood owl (Strix leptogrammica) with severe dehydration and diarrhea

A new avian Cryptosporidium genotype in a 1-month-old caged brown wood owl (Strix leptogrammica)... A 1-month-old brown wood owlet (Strix leptogrammica) purchased from a wholesaler and housed as a companion bird by an individual owner in Japan showed severe dehydration and anorexia following a week of vomiting and severe diarrhea. A great number of approximately 5 × 4-μm-sized Cryptosporidium oocysts were found in the feces by microscopy. The owlet was administered subcutaneous fluid and intragastric tube feeding for 2 weeks, resulting in improvement of the condition with a decreased number of oocysts in the feces. At days 51 and 119, no oocysts were found in the feces by microscope and PCR detection. These results suggested that this parasite was a possible agent of severe diarrhea in the affected bird. Molecular analysis of DNA extracted from oocysts based on the 18SrRNA loci identified C. avium; however, analysis of actin and hsp (heat shock protein) genes identified a novel genotype indicating a mixed infection with C. avium and a novel genotype. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Parasitology Research Springer Journals

Abstract

A 1-month-old brown wood owlet (Strix leptogrammica) purchased from a wholesaler and housed as a companion bird by an individual owner in Japan showed severe dehydration and anorexia following a week of vomiting and severe diarrhea. A great number of approximately 5 × 4-μm-sized Cryptosporidium oocysts were found in the feces by microscopy. The owlet was administered subcutaneous fluid and intragastric tube feeding for 2 weeks, resulting in improvement of the condition with a decreased number of oocysts in the feces. At days 51 and 119, no oocysts were found in the feces by microscope and PCR detection. These results suggested that this parasite was a possible agent of severe diarrhea in the affected bird. Molecular analysis of DNA extracted from oocysts based on the 18SrRNA loci identified C. avium; however, analysis of actin and hsp (heat shock protein) genes identified a novel genotype indicating a mixed infection with C. avium and a novel genotype.
