Abstract |
Listeria monocytogenes, a bacterium common in the environment, has been linked to outbreaks of food-borne illness, with high hospitalisation and mortality rates. Although L. monocytogenes has been found in Egypt's animals, food and environment, very little is known about the threat it poses to Egyptians' health. Analysis was used to examine and compare the data acquired from three governorates(Giza- Sharkia Qaliubia) from different sources( sheep-humans-animal feed) for the presence of L. monocytogenes.All recovered isolates were confirmed morphologically and biochemically. Thirty-seven Listeria isolates (11.9%) were recovered from humans 5 (10%), sheep 31 (13.5%) and animal feed 1 (3.3% ). Sharkia has the highest prevalence of listeria 18(48.6%), followed by Giza 11(29.8%) then Qaliubia 8(21.6%). All recovered isolates and showed green-blue colonies and An opaque halo surrounded the colonies on ALOA agar and showed a narrow zone of β haemolysis on blood agar. Arrowhead, circle or rectangle zone of enhanced β-hemolysis which detects a CAMP-positive reaction |
