Abstract

To characterize the prevalence and assess the zoonotic transmission burden of Cryptosporidium species/genotypes in pet birds in Henan, China, 434 fecal samples were acquired from 14 families of birds in pet shops. The overall prevalence of Cryptopsoridium was 8.1% (35/434) by the Sheather's sugar flotation technique. The Cryptosporidium-positive samples were analyzed by DNA sequence analysis of the small subunit (SSU) rRNA gene. Three Cryptosporidium species and two genotypes were identified, including C. baileyi (18/35 or 51.4%) in five red-billed leiothrixes (Leiothrix lutea), four white Java sparrows (Padda oryzivora), four common mynas (Acridotheres tristis), two zebra finches (Taeniopygia guttata), a crested Lark (Galerida cristata), a Gouldian finch (Chloebia gouldiae), and a black-billed magpie (Pica pica); Cryptosporidium meleagridis (3/35 or 8.6%) in a Bohemian waxwing (Bombycilla garrulus), a Rufous turtle dove (Streptopelia orientalis), and a fan-tailed pigeon (Columba livia); Cryptosporidium galli (5/35 or 14.3%) in four Bohemian waxwings (Bombycilla garrulus) and a silver-eared Mesia (Leiothrix argentauris); Cryptosporidium avian genotype III (3/35 or 8.6%) in two cockatiels (Nymphicus hollandicus) and a red-billed blue magpie (Urocissa erythrorhyncha); and Cryptosporidium avian genotype V (6/35 or 17.1%) in six cockatiels (Nymphicus hollandicus). Among the pet birds, 12 species represented new hosts for Cryptosporidum infections. The presence of C. meleagridis raises questions on potential zoonotic transmission of cryptosporidiosis from pet birds to humans.
