Abstract
In the present study, a total of 89 clinical samples including; wound pus (n=53), urine (n=23), sputum (n=8), stool (n=3), and blood (n=2), were obtained from patients at Tanta Cancer Center. from these samples, 110 clinical isolates were recovered. All the recovered bacterial isolates were identified using microscopical examination and standard biochemical tests. Escherichia coli (n=46) was the main isolated Gram negative organism, followed by Proteus mirabilis (n=19), Pseudomonas aeruginosa (n=11), and Klebsiella pneumoniae (n=9). A number of less-frequent Gram negative bacterial species were isolated and identified such as, Enterobacter gergoviae (n=2),Proteus vulgaris (n=2), Serratia liquefaciens (n=2), Chromobacterium violaceum (n=1), Citrobacter freundii (n=1), Salmonella enterica ssp. arizonae (n=1), and Shigella flexeneri (n=1). Staphylococcus aureus represented 73.3% of the total Gram positive isolates. Monomicrobial Gram negative infections accounted for 69.7% of infections, followed by polymicrobial infections (21.3%), and monomicrobial Gram positive infections (9%). The majority of polymicrobial infections (84%) had a Gram negative component, with E. coli being the most common organism isolated, and 79% of polymicrobial infections were caused exclusively by multiple species of Gram negative bacilli.
