indicator(yellow in positive test but faint red for control
medium).
4.2- Enterobacteria in Human urine:
Eighteen, 30 and 5 urine samples from female urine
male and children contained 14/18(77.7%), 22/30 (73.33%)
and 3/5(60%) isolates respectively (table 3). Concerning
lactose fermenter isolates, the samples contained 13/18
(72.2%), 18/30 (60.0%) and 3/5(60%) isolates
respectively(table 3).
Concerning non lactose fermenter isolates, the samples
contained 1/18(5.5%), 4/30(13.33%) and 0.0(0.0%) isolates
respectively(table 3).
4.3-Biotyping of chicken Enterobacteria.
Biochemical tests including, growth on MaCconkeyۥs
medium oxidation fermentation test (O-F), growth on triple
sugar iron agar (TSI, fig.3), Xylose Lysine decarboxylase
(XLD.fig.2), Indol, M.R, V.P, Citrate(fig.4), urease, sugar
