| 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 |
| cryptosporidium andersoni is the predominant species in post-weaned and adult dairy cattle in china. | dairy industry plays an important role in the agricultural economy of china. to estimate the prevalence and public health significance of cryptosporidiosis in post-weaned and adult dairy cattle in china, during four consecutive years (from 2006 to 2009), a total of 1315 fecal samples from 22 dairy cattle farms in ten prefectures in henan province were examined for the presence of cryptosporidium oocysts. the overall prevalence of cryptosporidium was 7.9%, with the highest infection rate (11.3%) ... | 2010 | 20884374 |
| prevalence, molecular characterization and zoonotic potential of cryptosporidium spp. in goats in henan and chongqing, china. | to estimate the prevalence and public health significance of cryptosporidiosis in goats in china, 1265 fecal samples from seven farms in henan province and chongqing city were examined for cryptosporidium oocysts. the overall infection rate of cryptosporidium spp. was 3.48% (44/1256). significant difference was observed among age groups, with the post weaned kids having the highest infection rate (4.58%; ρ<0.01). cryptosporidium spp. were characterized by pcr-restriction fragment length polymorp ... | 2014 | 24721256 |
| 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 |
