Abstract
There are limited reports that discuss the prevalence of Yersinia enterocolitica and Cronobacter sakazakii in Africa, especially in Egypt. The current study aimed to provide data about the prevalence of Y. enterocolitica and C. sakazakii in animals, humans, and dried milk in New Valley Governorate, Egypt. Samples were collected from fresh milk and feces from dairy cattle and sheep farms, in addition to human stool samples and also milk powder. The present study was the first report to isolate Y. enterocolitica from dried milk and C. sakazakii from sheep. By using bacteriological isolation, the prevalence rates of Y. enterocolitica in cow milk, cow feces, sheep milk, sheep feces, human stool, powdered milk and powdered infant formula were 12.5%, 14.85%, 5.71%, and 7.5%, 13.24%, 20% and 8.16%, respectively. On the other hand, the prevalence rates of C. sakazakii in cow milk, cow feces, sheep milk, sheep feces, of human stool, powdered milk and infant formula were 9.38%, 11.38%, 4.29%, 4.25%, 5.88%, 15%, and 6.8%, respectively. The presence of relatively high prevalence rates of Y. enterocolitica and C. sakazakii in animal and human samples reveals the high zoonotic importance of these bacteria.
