Acinetobacter junii: A rare pathogen causing opportunistic infections from a tertiary care hospital

Abstract

Acinetobacter are Gram-negative coccobacilli comprising of Acinetobacter baumannii and Acinetobacter lwoffii as commonly isolated species of the genus Acinetobacter from clinical specimens. The other species of the genus Acinetobacter are rarely isolated from clinical specimens and usually considered as environmental contaminants. Acinetobacter junii has rarely been reported globally causing opportunistic infections in immunocompromised individuals. We reported a series of four clinical cases due to Acinetobacter junii infection in a tertiary care teaching institute from Uttar Pradesh, India. Among these reported cases first case was peritonitis, second and third cases were catheter associated urinary tract infection and fourth case was ventilator associated pneumonia. All these cases were reported among immunocompromised individuals and Acinetobacter junii was identified by VITEK-2 Compact automated system which was further reconfirmed by conventional biochemical tests. These isolates were found to be susceptible against most of the antimicrobials.
