Abstract
Acinetobacter has emerged as significant hospital pathogen involved in
outbreaks of hospital infections, notoriously known to acquire antibiotic resistance to
most of the commonly prescribed antimicrobials. Many risk factors are associated with
Acinetobacter infections, especially in patients in intensive care unit (ICU).
Acinetobacter species tend to be resistant to a variety of antibiotics and thus the
infections are difficult to treat. This study aims to isolate Acinetobacter from various
clinical samples and to determine its antimicrobial sensitivity pattern. The objectives of
the present study were; 1) To isolate Acinetobacter species from various clinical
samples. 2) To study their Antibiogram pattern of the Isolated Organisms. A total of 93
Acinetobacter species were isolated from various clinical samples. Identification of
Acinetobacter was done on the basis of hemolysis on blood agar, growth at 42ÂșC, and
oxidation fermentation test. Antibiotic susceptibility testing was done as per standard
CLSI guidelines (2017). Maximum isolation of Acinetobacter species were from pus or
wound swabs 57 (61.29%) followed by sputum and tracheal secretions 21 (22.58%)
and urine 15 (16.12%) samples. Most of the strains were sensitive to imipenem (97%),
piperacillin-tazobactam (91.39%), and getifloxacin (86%) whereas, maximum
resistance was observed to co-trimoxazole (10.75%) and gentamicin (9.67%).
Acinetobacter spp. has emerged as a major nosocomial pathogen. Broad-spectrum
antibiotics should be used with caution and only after antibiotic susceptibility testing.
Early identification and continued surveillance of prevalent organism will help prevent
the spread of Acinetobacter in hospital environment. Empirical antibiotic policy should
be determined for each hospital according to the resistance rates of that hospital setting.
