Summary: | Amebiasis is a worldwide parasitic zoonosis, with symptoms of abdominal discomfort, indigestion, diarrhea, and even death. However, limited information about the prevalence of
Entamoeba
spp. in experimental nonhuman primates (NHPs) in southwestern China is available. The objective of the current study was to investigate the frequency and species identity of
Entamoeba
to evaluate potential zoonotic risk factors for
Entamoeba
spp. infection in experimental NHPs. A total of 505 fecal samples were collected from NHPs (macaques) and analyzed by PCR analysis the small subunit rRNA (SSU rRNA) gene of
Entamoeba
spp. Forty-seven specimens were positive for
Entamoeba
spp., and the prevalence of
Entamoeba
spp. was 9.31% (47/505). Significant differences in the prevalence rates among the three breeds (
P =
0.002 < 0.01,
df
= 2,
χ
2
= 12.33) and feed types (
P =
0.001 < 0.01,
df
= 1,
χ
2
= 10.12) were observed. Altogether, four
Entamoeba
species, including
E. dispar
(57.44%),
E. chattoni
(29.78%),
E. histolytica
(6.38%), and
E. coli
(6.38%), were identified by DNA sequence analysis. The results suggested a low prevalence but high diversity of
Entamoeba
species in experimental NHPs in Yunnan Province, southwestern China. Results of this study contribute to the knowledge of the genetic characteristics of
Entamoeba
spp. in NHPs. |
