Time gap between oocyst shedding and antibody responses in mice infected with Cryptosporidium parvum.
We observed the time gap between oocyst shedding and antibody responses in mice (3-week-old C57BL/6J females) infected with Cryptosporidium parvum. Oocyst shedding was verified by modified acid-fast staining. The individually collected mouse sera were assessed for C. parvum IgM and IgG antibodies by enzyme-linked immunosorbent assay from 5 to 25 weeks after infection. The results showed that C....
متن کاملIsolation of Cryptosporidium parvum Oocyst From Infected Feces
Introduction Cryptosporidium is a genus of Apicomplexa phylum parasites that can cause a respiratory and gastrointestinal illness (cryptosporidiosis) that primarily involves watery diarrhea (intestinal cryptosporidiosis) with or without a persistent cough (respiratory cryptosporidiosis) in both immunocompetent and immunodeficient humans (1-3). A number of Cryptosporidium species infect mammals ...
متن کاملa study of oocyst shedding pattern and weight changes in neonatal calves experimentally infected with cryptosporidium parvum
background: cryptosporidium parvum is a protozoan parasite which belongs to apicomplexa phylum. the parasite infects both wild and domesticated animals and human beings as well. objectives: the purpose of the present study was to detect oocyst shedding and diarrhea pattern in experimental cryptosporidiosis and their correlation with weight loss in neonatal calves. methods: twelve holstein calve...
متن کاملConcurrent response to challenge infection with Cryptosporidium parvum in immunosuppressed C57BL/6N mice
We investigated the response to challenge infection with Cryptosporidium parvum oocysts in immunosuppressed C57BL/6N mice. In the primary infection, fecal oocyst shedding and parasite colonization were greater in immunosuppressed mice than in nonimmunosuppressed mice. Compared with primary infection, challenge infection with C. parvum didn't show any oocyst shedding and parasite colonization. E...
متن کاملIsolation of Small Number of Cryptosporidium parvum Oocyst Using Immunochromatography
BACKGROUND Cryptosporidium parvum causes severe gastroenteritis in immunocompromised human and new borne animals. The organism can be transmitted through water. Since small number of C. parvum is infectious, the aim of the present study was to develop a chromatography method for the isolation of C. parvum oocyst in samples with limited number of oocysts. METHODS Antibody was prepared against ...
