Isolation of Enterobacteria ina Slaugter House in Khartoum State

The objectives of this study were to determine the Enterobacterial load in mutton and to identify the type of enterobacteria causing contamination. Sixty sheep carcasses ina Slaughter house at Khartoum state were randomly chosen for this study, and samples were collected during the beriod 17/1/2010 – 15/4/2010 . Samples of 12cm 2 were asptically dissected from the neck regon and transferred immediately in an ice box to microbiology laboratory . Each sample was tested for viable Enterobacteria. Members of Enterobacteria were identified to the species level. Viable Enterobacteriacounts in samples of mutton ranged between 8.3 ×10 CFU/Cm 2 and 3.7×10 4 CFU/Cm 2 using the average method. When farmilaae method was used, the count ranged between 3.7 CFU/Cm 2 and 4.3×10 3 CFU/Cm 2 Ten (16.6%) isolates from the total samples were identified, based on their morphology and biochemical characters. Bacterial isolates were Klebsiella aerogenswhich counted for 13.3% of the isolates and Enterobacter erogens was confirmed in 3.3% sample. ix ﺺﺨﻠ
