Abstract:
This study was conducted in Khartoum teaching hospital during the
period from May to July 2005. A total of 109 patients (with mean age 36
year, range 5-85 years) were included (50 from urology & 59 from
orthopedic units). Specimens (urine and wound swab) were collected
from each subject (urine & swab) and processed for isolation of the
bacterial cause. The isolated bacteria were identified then subjected to
antimicrobial sensitivity test using Kirby-Bauer technique.
A total of 87 bacterial isolates were identified in the two units.
In urology unit, the most common pathogens were E. coli 18 (51.4%) and
Pseudomonas spp 8 (22.9%).
In orthopedic unit the most common pathogens were Staphylococcus
aeureus 19 (36.5%), E. coli 10 (19.2%), Pseudomonas spp 9 (17.3%)
,Proteus spp 9 (17.3%) and Coliforms were 5 (9.7%) .
The antimicrobial susceptibility of the 87 isolates to the commonly used
19 antimicrobial agents were performed using the standard Kirby-Baur
method.
The isolated organisms in urology unit showed high resistance to
Ciprofloxacin, Cefuroxime and Cotrimoxazole. And high susceptiblity to
Imepenim & Meropenem.
The isolated organisms in orthopedic unit showed high resistance to
Gentamicin and high sensitivity to Imipenem & Meropenem.
