| characteristics of cryptosporidium transmission in preweaned dairy cattle in henan, china. | to estimate the prevalence and public health significance of cryptosporidiosis in preweaned calves in china, 801 fecal samples from eight farms in seven areas in henan province were examined for cryptosporidium oocysts. the overall infection rate of cryptosporidium was 21.5%, with the farm in xinxiang having the highest prevalence (40%). no significant difference in infection rates was observed between seasons. cryptosporidium spp. were characterized by pcr-restriction fragment length polymorphi ... | 2010 | 21177898 |
| prevalence and molecular characterization of cryptosporidium spp. and giardia duodenalis in dairy cattle in beijing, china. | 822 fecal samples from cattle in six areas of beijing were examined with microscopy for cryptosporidium oocysts and giardia cysts. the overall infection rates for cryptosporidium spp. and giardia duodenalis were 2.55% and 1.09%, respectively. cryptosporidium was only detected in calves and heifers, whereas g. duodenalis was found in all age groups. cryptosporidium spp. were characterized with a pcr-restriction fragment length polymorphism analysis and dna sequence analysis of the small subunit ( ... | 2016 | 26921041 |
| genotyping and subtyping cryptosporidium parvum and giardia duodenalis carried by flies on dairy farms in henan, china. | cryptosporidium and giardia are important causes of diarrhea diseases in humans and animals worldwide, and both of them are transmitted by the fecal-oral route, either by direct contact or by the ingestion of contaminated food or water. the role of flies in the mechanical transmission of cryptosporidium and giardia has been receiving increasing attention. to date, no information is available in china about the occurrence of cryptosporidium and giardia in flies. we here investigated cryptosporidi ... | 2014 | 24742088 |
| infection rate of giardia duodenalis, cryptosporidium spp. and enterocytozoon bieneusi in cashmere, dairy and meat goats in china. | cryptosporidiosis, microsporidiosis, and giardiasis contribute significantly to the high burden of zoonotic diarrhea worldwide. goats constitute an important species in animal agriculture by providing cashmere wool, meat, and dairy products for human consumption. however, zoonotic pathogens with the potential to cause morbidity and to degrade production have been reported frequently in goats recently. the present study examined 629 fecal specimens from goats, including 315 cashmere goats, 170 da ... | 2016 | 27017915 |
| common occurrence of cryptosporidium hominis in horses and donkeys. | extensive genetic variation is observed within the genus cryptosporidium and the distribution of cryptosporidium species/genotypes in humans and animals appears to vary by geography and host species. to better understand the genetic diversity of cryptosporidium spp. in horses and donkeys, we characterized five horse-derived and 82 donkey-derived cryptosporidium isolates from five provinces or autonomous regions (sichuan, gansu, henan, inner mongolia and shandong) in china at the species/genotype ... | 2016 | 27264727 |
| cervine genotype is the major cryptosporidium genotype in sheep in china. | to identify cryptosporidium species/genotypes in sheep in china and to elucidate the endemic transmission of cryptosporidiosis, a total of 1,701 fecal samples from five farms in four prefectures in henan province (central china) were examined. eighty-two cryptosporidium-positive samples were analyzed by polymerase chain reaction (pcr)-restriction fragment length polymorphism analysis of the small subunit (ssu) rrna gene and pcr analysis of the 60 kda glycoprotein (gp60) gene, and 41 were further ... | 2010 | 19904561 |
