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 ( ...201626921041
zoonotic cryptosporidium spp. and enterocytozoon bieneusi in pet chinchillas (chinchilla lanigera) in china.cryptosporidium and enterocytozoon bieneusi are the most prevalent protist pathogens responsible for inducing human and animal diseases worldwide. the aim of the present work was to determine the occurrence of cryptosporidium spp. and e. bieneusi in pet chinchillas in china. one hundred forty fecal samples were collected from four cities: beijing, zhengzhou, anyang and guiyang. they were then examined with pcr amplification of the small subunit ribosomal rna (ssu rrna) of cryptosporidium spp. an ...201525988830
evaluation of spore wall protein 1 as an alternative antigen for the diagnosis of encephalitozoon cuniculi infection of farmed foxes using an enzyme-linked immunosorbent assay.the sequence encoding swp1 was cloned from the genome of encephalitozoon cuniculi. recombinant swp1 (rswp1) was expressed in escherichia coli and used to detect e. cuniculi infections in farmed foxes and dogs with an indirect enzyme-linked immunosorbent assay (elisa) in the present study. the sera of foxes infected with e. cuniculi could be distinguished from the sera of foxes infected with toxoplasma gondii, neospora caninum, and cryptosporidium parvum using the elisa. in total, 198 fox samples ...201424830821
