Klebsiella pneumoniae is a Gram-negative rod-shaped (bacillus) bacteria that is particularly adept to accepting resistance genes in horizontal gene transfer. It is commonly also resistant to phagocyte treatment due to its thick biofilm with strong adhesion to neighboring cells.[1] Certain strains have also developed β-lactamases that allow them to be resistant many of the commonly used antibiotics, including carbapenems, which has led to the creation of carbapenem-resistant K. pneumoniae (CRKP), for which there are very few antibiotics in development that can treat infection.[13]
