Pseudomonas aeruginosa is a common etiological agent causing various infections. The isolates can be mucoid or nonmucoid. It harbors innate resistance to a broad range of antibiotics.
The aim of this study is to determine the frequency of the mucoid and nonmucoid isolates along with their antibiogram from respiratory samples.
Materials and methods
A total of 220 isolates of P. aeruginosa were obtained from various clinical specimens and 72 from respiratory samples. Pseudomonas aeruginosa was identified by standard colony morphology and bacteriological methods, and antibiotic sensitivity was determined by the Kirby Bauer method.
Out of the 72 respiratory samples, 15 (20.83%) were mucoid strains and 57 (79.87%) nonmucoid strains. The mucoid colonies showed high resistance to antibiotics, such as co-trimoxazole (COT) (73.33%), ciprofloxacin (CIP) (60%), and ceftazidime (CAZ) (53.33%), whereas high resistance rate among the nonmucoid isolates were seen in (COT) (78.95%), (CIP) (71.93%), (CAZ) (54.39%), cefepime (52.63%).
The antibiotic susceptibility pattern helps in constituting the guidelines for treatment and management of the infections by P. aeruginosa.
