Ten out of 14(71.42%) E.coli from one day old chicks isolates<br />
were sensitive to doxycyclin. Tsai and Fang found that over 90% of<br />
E.coli isolates were resistant to oxytetracycline, chlortetracycline,<br />
tetracycline and doxycyclin. Shome and his colleagues found that all<br />
E.coli isolates were also resistant, on the other hand, it was found all<br />
E.coli isolates collected from 2 commercial unites and from free range<br />
chickens from 3 villages were sensitive to chlortetracycline and<br />
doxycyclin, Mishra(1995).<br />
Eight out of 14(57.14%) E.coli isolates from one day old chicks<br />
were sensitive to erythromycin, Activity percentage 73.8% of<br />
erythromycin was mentioned by Osman (1992), meanwhile resistance<br />
percentage 100% against erythromycin and pencillin G was recorded<br />
by Abd-El-Mawla (1998).<br />
Nine out of 14(64.28%) E.coli isolates from one day old chicks<br />
were sensitive to rifampicin. This result was similarly stimulated by<br />
Prescott and Yieldding (1990).<br />
Ten out of 14(71.42%) E.coli isolates from one day old chicks<br />
were sensitive to streptomycin. Meaning that streptomycin resistance<br />
percentage was 28.58%. This result agreed with that obtained by Abd-<br />
El-Mawla (1998) who reported resistance percentage 39.1% for<br />
