E. Coli

Review of Literature
pencillin (68.88%), furazolidone (83.13%) and kanamycin (61.67%)
ampicillin (51.12%), chloramphenical (50.23%), and streptomycin
(44.84%).
Filali et al. (1988) isolated sixty two strains of E. coli (O:78,
O:1&O:2) from 58 broiler farms suffering from respiratory signs and
lesion characteristic to avian colibacillosis .All strains of isolated E.
coli were sensitive to colistin, flumequine and gentamycin .A few
strains were resistant to neomycin, nalidixic acid and trimethoprim.
The frequently strains Resistant to nitrofurans, sulfonamides,
chloramphenicol, spestinomycin and ampicillin was intermediate.
Most strains were resistant to tetracycline.
Adesiyum and Kaminjoli (1992) found that E. coli isolates were
most resistant to streptomycin (81%) and tetracycline (79%) and least
resistant to chloramphenicol (4%) and gentamycin (5%) The
predominant resistance pattern for all isolate was streptomycintetracycline
(28%).
Osman (1992) reported that the sensitivity test for E. coli gave
superior results with lincospectin (85-71%) followed by streptomycin,
nitro furans, erythromycin, gentamycin, flumequine, nalidixic acid,
sulfate with activity percentage of 80.9%, 78.5%, 73.8%, 6606%,
59.5%52. 3%,42.8%, 40.4%, 23.8% and 19.5%, respectively.
Meanwhile no effect could be observed with neomycin.
Dinh and Nguyen (1995) studied the efficiency of antibiotics
(streptomycin, chloramphenical, tetracycline, furazolidone, neomycin,
