Zoonotic cryptosporidiosis in man and animal in farms, Giza Governorate, Egypt.

To demonstrated the zoonotic cryptosporidiosis. A total of 189 farmers and their farm animals (200= 71 buffaloes, 59 cows, 43 sheep and 27 goats were examined. Stool samples Each stool sample was subjected to the direct wet smear method and Sheather's sugar flotation and acid-ether sedimentation techniques and stained with four stains (Modified Ziehl Neelsen, Safranin, methylene blue, Aniline carbol methyl violet and Giemsa). A positive statistically significant correlation was observed between farmers and their farm animals infected with cryptosporidium parvum proving a zoonotic potential for infection (r = 0.819 P <0.01 for cryptosporidiosis. For detection of Cryptosporidium, 100 % sensitivity was obtained when acid ether concentration technique was used and modified Ziehl-Neelsen stain revealed highest sensitivity of 92.1 %.
