a 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 کاملTime 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 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 ...
متن کاملStrategies for the control of Cryptosporidium parvum infection in calves.
Cryptosporidium parvum is a protozoan parasite that is now recognized as one of the leading causes of diarrhea in young calves. To date, there are no drugs or preventive measures available for the control of this disease. We have developed an oral vaccine that, when given to calves at birth, protects against experimental challenge with C. parvum. However, when field tested on a large dairy oper...
