Abstract:

The prevalence of multi drug resistant gram-negative bacteria to commonly first line drugs in blood is a serious problem in Equatorial Guinea and other world. This is the first study describing antibiotic resistance analysis of blood stream infection in Equatorial Guinea. Our study presents alarming rate of inefficiency of the most commonly prescribed drugs to treatment Klebsiella pneumoniae, Escherichia coli and Acinetobacter species isolates as the most frequency etiologic agents in blood stream infection. Out of 1849 blood culture the bacterial etiological agents were isolated from 196 (10.6%) samples. E. coli (n = 22), K. pneumonia (n = 39) and Acinetobacter (n = 17) represent 71.6% of all gram negative bacterial isolates. Almost all isolates of K. pneumonia and Acinetobacter sp. (92.1% and 100%, respectively) and about 50% of E. coli strains possessed extended-spectrum β-lactamase activity. Alarming level of multi drug resistant gram negative strains was observed. E. coli and K. pneumonia
