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 |
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 |
genetic characterizations of cryptosporidium spp. and giardia duodenalis in humans in henan, china. | cryptosporidium and giardia infections are common causes of diarrhea worldwide. to better understand the transmission of human cryptosporidiosis and giardiasis in henan, china, 10 cryptosporidium-positive specimens and 18 giardia-positive specimens were characterized at the species/genotype and subtype levels. cryptosporidium specimens were analyzed by dna sequencing of the small subunit rrna and 60kda glycoprotein genes. among those genotyped, nine belonged to c. hominis and one c. felis, with ... | 2011 | 20599984 |
multilocus genotyping of giardia duodenalis in dairy cattle in henan, china. | giardia duodenalis is a common and widespread intestinal protozoan parasite of both humans and animals. previous epidemiological and molecular studies have identified giardia infections in different animals and humans, but only limited information is available about the occurrence and genotypes of giardia in cattle in china. in this study, we determined the occurrence of giardiasis and genetically characterized g. duodenalis in dairy cattle in henan province, central china. the overall prevalenc ... | 2014 | 24971639 |
prevalence of zoonotic giardia duodenalis assemblage b and first identification of assemblage e in rabbit fecal samples isolates from central china. | 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. duodenalis in rabbits in china. in total, 955 fecal samples were collected from rabbits during 2008-2011 in henan province, central china. the overall prevalence of g. duodenalis was 8.4% (80/955) on microscopic analysis, with the highest infection rate (11.3%) in rabbits aged 91-200 d. all g. duodenalis-positive isolates were characterize ... | 2015 | 26040441 |
infection rate and genetic diversity of giardia duodenalis in pet and stray dogs in henan province, china. | giardia duodenalis is an important protozoan parasite that is known to be zoonotic. to assess the potential zoonotic transmission of giardiasis from dogs and to identify genetic diversity of g. duodenalis in dog populations, we examined the infection rate and genotypes of g. duodenalis in both pet dogs (from pet dog farms, pet shops, pet hospitals, pet markets) and stray dogs of different ages in henan province, china. a total of 940 fresh fecal specimens were collected from 2007 to 2013 in hena ... | 2016 | 26631754 |
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 |
prevalence and genotyping of giardia duodenalis isolated from sheep in henan province, central china. | giardia duodenalis is a gastrointestinal protozoan that infects sheep. it is a well-known zoonotic pathogen and sheep have been implicated as a source of human infection. however, there have been few studies of its potential threat to public health in china. we used a multilocus analysis of the beta-giardin (bg), glutamate dehydrogenase (gdh), and triose phosphate isomerase (tpi) genes to examine the occurrence and genotype distribution of g. duodenalis in sheep in china. in total, 716 fresh fae ... | 2016 | 26861620 |
