(2004)

Supervisor: Dr. Khalaf S. Al – Delaimy
The bacterial content of five brands of broiler carcasses, collected from one of
the main stores in Amman city, during refrigerated storage at 4 C and the antagonism
between Lactobacillus casei subsp. casei and Staphylococcus aureus were studied.
The bacterial count included aerobic plate count (APC), psychotrophs,
Enterobacteriaceae, lactic acid bacteria (LAB) and Staphylococcus aureus. It was
found that, the initial counts of the five selected bacterial groups, ere high and
increased steadily but not equally during the refrigerated storage period of six days.
The difference between the initial to final counts were, 1.8, 3.6, 1.4, 0.8 and 1.0
respectively. Organolyptic spoilage of the carcasses was apparent after five to six days
refrigeration, while the numbers of APC and psychotriphs exceeded Log 7. Isolation,
purification, maintenance and characterization of each of L.casei subsp. casie and
S.aureus to be used for antagonistic study were carried out. The results of antagonistic
effect after dipping the broilers in the pure suspension of L.casei, show the latter was
