Original publication title: Enterocytozoon bieneusi genotypes in dogs in Bogota, Colombia.

Species:
dog

Plain-English summary

A group of dogs in Bogota, Colombia, were found to be infected with a parasite called Enterocytozoon bieneusi, which can also affect humans. Out of 120 dogs tested, about 15% were positive for this parasite, with more male dogs affected than females. The infected dogs ranged in age from 2 to 14 years. This is significant because two of the genotypes identified in the dogs are known to cause illness in humans. Pet owners should be aware of this parasite and discuss any concerns with their veterinarian.

Abstract

Enterocytozoon bieneusi was detected in dogs in Bogota, Colombia for the first time. Of 120 dogs, 15% were positive by polymerase chain reaction (PCR). Infected dogs ranged from 2 to 14 years of age, and more male than female dogs were infected with E. bieneusi (20% versus 5%). All PCR-positive specimens were sequenced and three genotypes were identified. A dog-specific genotype (PtEbIX) was identified in feces from 16 dogs. For two dogs, the nucleotide sequences obtained were genetically identical to the E. bieneusi Peru 5 and K genotypes previously reported as human pathogens. This is the first time that Peru 5 and K genotypes have been identified in dogs. This study confirms that dogs are infected with both human pathogenic and host-specific genotypes.
