Background: The genus Klebsiella of Enterobacteriaceae family is ubiquitous in nature. They cause many nosocomial infections like pneumonia, urinary tract infections, wound infections, bacteremia and septicemia. Multidrug resistance is seen in Klebsiella which serves as the most common cause of increased morbidity and mortality. This study reveals the prevalence and antibiotic sensitivity pattern of Klebsiella species from various clinical samples. The primary objectives are as follows: To isolate and characterize Klebsiella species from various clinical samples. To study the antibiotic susceptibility pattern of Klebsiella isolates.

Methods: This prospective study was conducted in our tertiary care hospital during the period from August 2019 to October 2019. A total of 3521 samples were tested during this period. The samples include blood, sputum, urine, and pus.

Results: Out of the total samples tested,1106 samples were showing the growth of the organisms. Among this,351 were identified as Klebsiella species and the highest rate of isolation of Klebsiella species is from the sputum sample and also the same was reported high in medical wards. The study also shows that the isolation of Klebsiella species shows male preponderance when compared to females. The antibiotic sensitivity pattern was done by Kirby-Bauer's disc diffusion method and the sensitivity was noted to be higher to amikacin and ciprofloxacin.

Conclusions: Thus, this study shows the prevalence rate of Klebsiella species and sensitivity pattern of Klebsiella, which may help select appropriate antibiotics and prevent overuse and misuse of antibiotics.
