Prevalence of Zoonotic Giardia duodenalis Assemblage B and First Identification of Assemblage E in Rabbit Fecal Samples Isolates from Central China.

摘要: Giardia duodenalis is an important zoonotic pathogen, causes diarrhea in humans and animals worldwide. To date, few data are available on the prevalence of G. rabbits China. In total, 955 fecal samples were collected from during 2008-2011 Henan Province, Central The overall was 8.4% (80/955) microscopic analysis, with highest infection rate (11.3%) aged 91-200 d. All duodenalis-positive isolates characterized at small subunit ribosomal RNA, β-giardin (bg), glutamate dehydrogenase (gdh), triosephosphate isomerase genes. Two assemblages a mixed assemblage detected rabbits: B (n = 26), E 2), 4). Assemblage showed variability nucleotide sequences belonging to so-called subtype BIV, based analysis multiple This first report rabbits, one novel identified through sequence gdh bg genes, respectively. Our suggest that may be reservoirs cysts potentially infectious humans.
