Abstract
Cryptosporidium is an important protozoan, causing diarrhea in animals and humans. In spite of the importance of this parasite to veterinary medicine and public health, in some parts of the world, including Egypt and Kuwait a little information is still scanty about the epidemiology and risk factors associated with the infection. This study was conducted to fill the gaps of knowledge about the prevalence and risk of transmission of Cryptosporidium in cattle and camel farms. Determination the genotypes and subtypes of Cryptosporidium species in cattle and camels.
A cross sectional study (during the period extended from October 2014 to September 2015) was designed to investigate Cryptosporidium infection by fecal sampling at Sharkia Province, Egypt (50 cattle and 50 camels using ZN stain) where Cryptosporidium species was detected in 28% and 12% in cattle and camels respectively. Also, 400 cattle and 253 camels in Kuwait were examined for Cryptosporidium spp. by 2 microscopy tests, concentration floatation (CF) and Modified Ziehl-Nielsen staining (ZN), and 2 immunologic techniques, lateral immunochromatography assay (IC) and enzyme linked immunosorbant assay (ELISA). High infection rates were recorded in cattle (23%) and camels (4%) in Kuwait, using IC, indicating that this method was superior to other methods in detection of Cryptosporidium spp.
In cattle, Cryptosporidium prevalence was the highest (28%) and (23%) in Egypt and Kuwait, respectively, followed by Escherichia coli.
