ABSTRACT

Advance bacteria have acquired several mechanisms to deal with antibiotics and are becoming more powerful with the passage of time. Klebsiella pneumoniae belonging to the class of Enterobacteriaceae is also a part of this race and is becoming resistant to almost all types of antibiotics. Colistin which was the last option for treatment is now becoming susceptible to the resistant strains of Klebsiella pneumoniae. The modified strain is contributing to human infection via antibiotic resistance and is becoming virulent with the passage of time leading to increase morbidity and mortality rates. On the basis of observations and studies, the first part sum up some important facts associated with the onset of resistance in Klebsiella pneumoniae and the symptoms associated with the wild and virulent types. Owing to the ability of antibiotic resistance of K. pneumonia cause some infections (UTI and Liver abscesses) in humans are discussed in second part of review.
