| 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 |
| occurrence of bovine giardiasis and endemic genetic characterization of giardia duodenalis isolates in heilongjiang province, in the northeast of china. | to determine the prevalence of bovine giardiasis in heilongjiang province in china and to molecularly characterize giardia duodenalis, feces were collected from 814 dairy and beef cattle ranging in age from 6 days to 9 years. clinical symptoms of diarrhea were recorded at the time of sampling. the g. duodenalis infection rate in cattle was 5.2 % (42/814) as determined by lugol's iodine staining. g. duodenalis assemblages and subtypes were genetically diagnosed by sequence analysis of the triosep ... | 2012 | 22398834 |
| genetic characterizations of giardia duodenalis in sheep and goats in heilongjiang province, china and possibility of zoonotic transmission. | giardia duodenalis is a widespread intestinal protozoan of both humans and mammals. to date, few epidemiological studies have assessed the potential and importance of zoonotic transmission; and the human giardiasis burden attributable to g. duodenalis of animal origin is unclear. no information about occurrence and genotyping data of sheep and goat giardiasis is available in china. the aim of the present study was to determine prevalence and distribution of g. duodenalis in sheep and goats in he ... | 2012 | 23029587 |
| genetic analysis of the gdh and bg genes of animal-derived giardia duodenalis isolates in northeastern china and evaluation of zoonotic transmission potential. | giardia duodenalis is a common intestinal parasite that infects humans and many other mammals, mainly distributing in some areas with poor sanitation. the proportion of the human giardiasis burden attributable to g. duodenalis of animal origin differs in different geographical areas. in mainland china, genetic data of the gdh and bg genes of g. duodenalis from animals are only limited in dogs and cats. the aim of the study was to provide information on the genetic characterizations of animal-der ... | 2014 | 24748379 |
| occurrence and multilocus genotyping of giardia intestinalis assemblage c and d in farmed raccoon dogs, nyctereutes procyonoides, in china. | giardia intestinalis, the only causative agent of human giardiasis, can infect a wide range of animals. as no information concerning the prevalence and genotyping of g. intestinalis in raccoon dogs in china is available, examination of 305 faecal samples from raccoon dogs in jilin province (n = 110), heilongjiang province (n = 40), liaoning province (n = 72), hebei province (n = 54) and shandong province (n = 29) was conducted to estimate the prevalence of g. intestinalis in raccoon dogs in nort ... | 2016 | 27576343 |
| prevalence and genetic characteristics of cryptosporidium, enterocytozoon bieneusi and giardia duodenalis in cats and dogs in heilongjiang province, china. | this study investigated 319 fecal specimens of cats (n=52) and dogs (n=267) from heilongjiang province, china for the prevalence and genetic characteristics of cryptosporidium, enterocytozoon bieneusi, and giardia duodenalis. pcr and dna sequence analysis of the small subunit rrna gene identified c. felis and c. parvum in one cat each (3.8%) and c. canis and c. ubiquitum in 6 dogs (2.2%). polymorphisms in the ribosomal internal transcribed spacer and phylogenetic analysis characterized zoonotic ... | 2015 | 25665462 |
| cryptosporidium cuniculus and giardia duodenalis in rabbits: genetic diversity and possible zoonotic transmission. | cryptosporidium and giardia are the two important zoonotic pathogens causing diarrhea of humans and animals worldwide. considering the human cryptosporidiosis outbreak and sporadic cases caused by c. cuniculus, the important public health significance of g. duodenalis and little obtained information regarding rabbit infected with cryptosporidium and giardia in china, the aim of this study is to determine the prevalence and molecularly characterize cryptosporidium and giardia in rabbits in heilon ... | 2012 | 22363600 |
| molecular identification and distribution of cryptosporidium and giardia duodenalis in raw urban wastewater in harbin, china. | contamination of the water supply by protozoa often causes outbreaks of cryptosporidiosis and giardiasis. the goals of the present study was to investigate the level of cryptosporidium and giardia duodenalis in wastewater from wastewater treatment plants in harbin, china, and to understand the endemic transmission characteristics of cryptosporidiosis and giardiasis. forty-eight domestic wastewater specimens from the two wastewater treatment plants in harbin city were collected from april 2009 to ... | 2011 | 21461728 |
