A total of 100 culture positive samples from these patients were included comprising of 68 samples of Endotracheal Tubes, 14 samples of Peritoneal Dialysis Catheters, 11 samples of Urinary Catheters and 7 samples of Central Venous Catheters. The most frequent catheter colonizing bacteria were Pseudomonas spp. [34.7%], Klebsiella spp. [27.8%]. Escherichia coli [23.5%], Staphylococcus aureus [5.2%], Coagulase negative Staphylococci [3.5%], Proteus spp. [3.5%], Streptococcus pyogenes [0.9%] and non-haemolytic Streptococci [0.9%].
