“…It is also lower than that reported in dairy cattle in Argentina (14.3%, 10/70) [16], cattle in USA (34.8%, 285/819) [17], and cattle in Brazil (17.5%, 79/452) [18]. These differences may be influenced by many factors, such as the sample size, animal species, and the region of sample collected, so that it is difficult to explain the real reasons among different studies.…”

Enterocytozoon bieneusi, the most common zoonotic pathogen of microsporidiosis, has been found in various animals and humans, but no information is available concerning the prevalence and genotypes of E. bieneusi in white yaks (Bos grunniens). In the present study, 353 faecal samples from white yaks in Tianzhu Tibetan Autonomous County, Gansu Province, Northwestern China, were collected and examined by PCR amplification of the internal transcribed spacer gene to estimate E. bieneusi prevalence and identify their genotypes. Of the 353 faecal samples, 4 (1.13%) were tested E. bieneusi-positive. Sequences analysis revealed that two known genotypes, namely, I (n = 1) and BEB4 (n = 2), and a novel genotype, namely, WCY1 (n = 1), were found in this study. Among them, genotype WCY1 was clustered into Group 1, and genotypes I and BEB4 belonged to Group 2. The present study firstly indicates the existence of E. bieneusi in yaks in Gansu Province, Northwestern China. This is also the first record of E. bieneusi in white yaks. Effective measures should be taken to control E. bieneusi infection in white yaks, other animals, and humans.

“…Occurrence of Cryptosporidium spp., G. intestinalis and E. bieneusi Cryptosporidium spp., G. intestinalis and E. bieneusi have been reported in several bovidae animals globally (Rinder et al, 2000;Giangaspero et al, 2005;Santín and Fayer, 2011;Lim et al, 2013;Abeywardena et al, 2013Abeywardena et al, , 2014Del Coco et al, 2014;Hogan et al, 2014;Mi et al, 2014;Wang et al, 2014b). In 2012, 47 faecal specimens from dairy cattle were examined by PCR in Shanghai, with 10, 24 and 17 positive for Cryptosporidium spp., G. intestinalis and E. bieneusi, respectively (Fayer et al, 2012).…”

“…According to previous molecular epidemiological data on E. bieneusi, summarized in Table 1, genotype EbpA has been found in 7 out of 11 countries reporting E. bieneusi infection in pigs, including wild boars, showing the widest distribution ( Table 1). The genotype has also been isolated from cattle, horses, mice, and birds (5,42 (43)(44)(45)(46). It has been commonly detected both in HIV-positive patients and in HIV-negative individuals (3).…”

bEnterocytozoon bieneusi is an emerging and clinically significant enteric parasite infecting humans and animals and can cause life-threatening diarrhea in immunocompromised people. Pigs are considered to be one of the main reservoir hosts of E. bieneusi based on their high prevalence rates and zoonotic genotypes in pigs. As an opportunistic pathogen, E. bieneusi infection of pigs can be inapparent, which leads to neglect in detecting this parasite in pigs and assessing the epidemiological role of pigs in the transmission of human microsporidiosis. In the present study, 95 healthy pigs aged 2 or 3 months were randomly selected from three areas in Heilongjiang Province, China. E. bieneusi isolates were identified and genotyped based on the small-subunit (SSU) rRNA and internal transcribed spacer (ITS) regions of the rRNA gene by PCR and sequencing. A high prevalence of E. bieneusi was observed, 83.2% (79/95) at the SSU rRNA locus versus 89.5% (85/95) at the ITS locus. Ten ITS genotypes were obtained, comprising six known genotypes-EbpA (n ‫؍‬ 30), D (n ‫؍‬ 19), H (n ‫؍‬ 18), O (n ‫؍‬ 11), CS-1 (n ‫؍‬ 1), and LW1 (n ‫؍‬ 1)-and four novel genotypes named HLJ-I to HLJ-IV; 70.6% (60/85) of E. bieneusi genotypes were zoonotic (genotypes EbpA, D, and O). The findings of a high prevalence of E. bieneusi in pigs and a large percentage of zoonotic genotypes indicate that pigs may play a role in the transmission of E. bieneusi to humans and may become an important source of water contamination in our investigated areas.
