Abstract
This study was carried out in Khartoum North area to isolate and identify the
bacteria associated with the respiratory tract infections of chickens.
Seventy eight samples were collected from five farms in Khartoum North
area one farm in each of Alkadaro, Umalgora, Almazallat and two farms in
Shambat. Samples were aseptically collected from different breeds of chickens
showing clear respiratory symptoms. The samples were nasal swabs, conjunctival
swabs, tracheal swabs and specimens from lungs. The sensitivity of bacteria
isolated from infected chicken to antibiotics was examined.
The collected samples showed bacterial growth in 64 (82.1 %) samples and
yielded 89 (114.1 %) isolates. Fifty two (66.7 %) of isolates were found to be
Gram positive bacteria and the remaining 37 (47.4 %) isolates were Gram negative
bacteria. The result of sensitivity test showed variable results, some showed high
sensitivity while others showed resistance.The most effective antibacterial drug
was Gentamicin (85.7%) but the lowest effective drug was Lincomycin (12.5%).
The result of this study described the bacterial respiratory diseases as the one
of the constrains to poultry production in Khartoum North area.
