Microbiological profile of pathogens in spontaneous bacterial peritonitis secondary to liver cirrhosis: a retrospective study.

Microbiological profile of pathogens in spontaneous bacterial peritonitis secondary to liver cirrhosis: a retrospective study. Trop Doct. 2020 Feb 18;:49475520905745 Authors: Mittal H, Wyawahare M, Sistla S Abstract Spontaneous bacterial peritonitis (SBP) is an acute bacterial infection of ascitic fluid without an obvious source. The prevalence of SBP in patients with cirrhosis is in the range of 10%-30%. With increasing use of antibiotics, there is a gradual shift in the causative flora of SBP from Gram-negative bacteria to Gram-positive and, more importantly, to drug-resistant bacteria. The aim of this retrospective study on 721 cases was to identify the prevalence of various organisms causing SBP along with their drug sensitivity and resistance patterns. A prevalence of 38.2% culture positivity was observed in our South Indian population. Escherichia coli was the most common pathogen isolated. Third-generation cephalosporins showed high rates of resistance, but a susceptibility of 74.5% to amikacin was found. Nonetheless, 42% of culture-positive isolates exhibited multidrug resistance, the highest rates being seen with Enterococcus faecium (64.2%) and Acinetobacter baumannii (71.4%).
