Fecal antibodies to Cryptosporidium parvum in healthy volunteers.
This study examined the intestinal antibody response in 26 healthy volunteers challenged with Cryptosporidium parvum oocysts. Fecal extracts were assayed for total secretory immunoglobulin A (IgA) and C. parvum-specific IgA reactivity. Specific IgA reactivity was standardized to IgA concentration and expressed as a reactivity index (RI). Anti-C. parvum fecal IgA (fIgA) increased significantly i...
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 کاملCryptosporidium parvum and Cryptosporidium andersoni infection in naturally infected cattle of northwest Iran
The protozoan intestinal parasite Cryptosporidium commonly infects cattle throughout the world and Iran. The present study was undertaken to determine the abundance and associated risk factors of Cryptosporidium infection in cattle herds of northwestern Iran. A total number of 246 fecal samples from 138 (56.1%) diarrheic (D) and 108 (43.9%) non-diarrheic (ND) cattle were rando...
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 ...
