INCIDENCE OF ENTEROBACTERIACEAE IN DRESSED CARCASSES OF SHEEP IN ISMAILIA GOVERNORATE.

Abstract

The mean value of APCs in the samples obtained from the intestines and the mesenteric lymph nodes were 2.6 x I 06 ± 2.3 x 105 and 4.9 x 105 ± 3.3 x 103 respectively.

Mean value of APCs in the samples of liver was 5 x I04 ± 2.7 x I04

meanwhile the mean value of the hepatic lymph nodes, 1.1 x I 05 ±

8.0 x 103 . Higher value was recorded from the gallbladder where the mean value of APCs attained 3.5 xI 05 ± 3.1 x Io'. As regard to the diaphragmatic muscles-the representative ofmutton in this study- the

mean value of APCs was 3.3 x I 04 ± 2 x I 04 .

79 % of mesenteric lymph nodes showed APCs count exceeding

105

while 61% ofthe intestines had counts ranged between 106 - 107.

Also, 77% of gallbladder samples had counts exceeding I 05 and attained to 106 meanwhile 70% of the examined liver sample showed APCs exceeding 104 Somewhat lower percentage (64 %) ofthe hepatic lymph nodes had the same count of l 04 .

62% of diaphragmatic muscle had a count between 105 to 106 .
