Cryptosporidiosis is a cosmopolitan parasitosis that affects a wide range of hosts including birds. As information concerning Cryptosporidium in birds is limited, the present study examined the prevalence and genotypes of Cryptosporidium in Java sparrows in Beijing and Shangqiu, northern China. Three hundred and fifty fecal samples were collected from Java sparrows (Lonchura oryzivora, 225 whit...
Cryptosporidium is an enteric parasite of public health significance that causes diarrhoeal illness through faecal oral contamination and via water. Zoonotic transmission is difficult to determine as most species of Cryptosporidium are morphologically identical and can only be differentiated by molecular means. Transmission dynamics of Cryptosporidium in rural populations were investigated thro...
Cryptosporidium and Giardia were characterized in a watershed in southern Ontario, Canada, over a 2½ year period. River samples were collected every two weeks, primarily near a municipal drinking water treatment plant intake. Cryptosporidium and Giardia were frequently detected with an overall occurrence rate of 88 and 97%, respectively. Giardia concentrations were higher than Cryptosporidium, ...
Several Cryptosporidium spp. are known to infect humans, but most cases of illness are caused by Cryptosporidium hominis or C. parvum. During a long-term genotyping in the United Kingdom, we identified 3 unusual Cryptosporidium genotypes (skunk, horse, and rabbit) in human patients with diarrhea.
In September 2001, a waterborne outbreak of gastroenteritis occurred in eastern France. Of 31 fecal samples from symptomatic individuals, 19 tested positive for Cryptosporidium with two PCRs targeting the Hsp70 and the 18S rRNA genes of CRYPTOSPORIDIUM: Sequencing of the PCR fragments produced sequences identical to that of Cryptosporidium parvum genotype 1.
Subtyping was conducted in late 2007 on 57 Cryptosporidium specimens from sporadic cases in Colorado, Idaho, New Mexico, and Iowa. One previously rare Cryptosporidium hominis subtype was identified in 40 cases (70%) from all four states, and the Cryptosporidium horse genotype was identified in a pet shop employee with severe clinical symptoms.
BACKGROUND Cryptosporidium spp. are common intestinal protozoa of humans and animals. There have been few studies conducted on the molecular characterizations of pig-derived Cryptosporidium isolates worldwide, especially in China. Thus, the aim of the present study was to understand the prevalence, distribution and genotypes of Cryptosporidium in pigs in Heilongjiang Province, China. METHODOL...
Whole-genome sequencing of Cryptosporidium spp. is hampered by difficulties in obtaining sufficient, highly pure genomic DNA from clinical specimens. In this study, we developed procedures for the isolation and enrichment of Cryptosporidium genomic DNA from fecal specimens and verification of DNA purity for whole-genome sequencing. The isolation and enrichment of genomic DNA were achieved by a ...
Cattle are frequently parasitized with an number of protozoan parasites but Giardia duodenalis, Cryptosporidium parvum and Cryptosporidium andersoni are of major zoonotic concern. These parasites case diarrhoea and impair body weight gain. Giardia and Cryptosporidium from cattle are potential zoonotic pathogens and contact with animals, manure or contaminated water is believed to lead to infect...
Abstract Background: Cryptosporidium, a protozoa coccidian, has recently been recognized as an important cause of acute and chronic diarrhea leading to dehydration. Since there was no survey about clinical symptoms of this parasite in adult patients in Chahar-mahal and Bakhtiari province, this study was carried out to define the clinical manifestation of Cryptosporidiosis in these areas. ...
