1- Enterobacteria were isolated from liver and spleen of chickens<br />

(broiler, one day old chicks and layers) with prevalence rate 83.05%.<br />

69.49% and 13.55% isolates were lactose fermenter and non-lactose<br />

fermenter respectively.<br />

2-Incidence of lactose fermenter among enterobacteria were 61.6%<br />

and 81.1% in broiler and in both layers and one day old chicks<br />

respectively, meanwhile Incidence of non lactose fermenter among<br />

enterobacteria were 24% and 5.88% in both layers and one day old<br />

chicks respectively,<br />

3-lactose fermenter isolates from human urine (female, male and<br />

children) represented 29.8%, 18/30 81.8% and 60% of total samples<br />

respectively, meanwhile non lactose fermenter isolates represented<br />

5.5%, 13.33% and 0.0(0.0%) of total samples respectively,<br />

4-Lactose fermenter isolates from broiler were E.coli and Citrobacter<br />

diversus among tested isolates and represented 68/107 (63.55%) and<br />

9/107 (8.41%) respectively. Meanwhile non Lactose fermenter isolates<br />

were salmonella, pseudomonas and proteus and represented 24/107<br />

(22.42%), 4/107(3.7%), 2/107(1.86%) respectively<br />

5-Lactose fermenter isolates from one day old chicks and layers (table<br />

4) were E.coli and Citrobacter diversus among tested isolates. They<br />
