RESUMEN
Objective: To assess the prevalence of common pathogens isolated in blood cultures in hospitalized patients at a tertiary care hospital of Lahore
Methods: The retrospective study was done on patients with a higher probability of bacteremia and/or fungemia. Majority of the patients belong to the neonatal and pediatric group, other cases were from ICU, CCU, medical and surgical units. The blood was drawn aseptically from the patient's vein, added to TSB broth, incubated and then cultured. The organisms isolated were identified by biochemical profiling
Results: This study included 1568 patients of blood stream infection [BSI]. Out of these, 225 [14.34%] patients yielded positive blood cultures and 1343 [85.65%] patients did not yield any growth. Among the positive blood cultures 89 [39.55%] were from neonates, 81 [36%] from pediatrics and 55 [24.4%] were from adults. The most common bacterial pathogen isolated in Gram positive organisms was CoNS i.e. 55 [24%] followed by Gram negative Pseudomonas 50 [22.2%], whereas in fungal infections the most common pathogen was Candida spp. 29 [12.88%]
Conclusions: The results of our studies shows the frequency of positive blood cultures in neonates and adults. We can conclude that the frequency is much higher in neonates than adults
