The study explored the prevalence of biofilm formers and its association with multidrug resistance in Klebsiella Pneumonia, a gram-negative bacterium that has high propensity to form antibiotic resistant strains and forms biofilms. Biofilms are complex microbial community with attributes that vary from planktonic cells. Antibiotic resistance is a property that has shown evidence to be higher in biofilms as compared to planktonic cells. Multi-drug resistance, a higher form of antibiotic resistance, is defined as resistance to at least one agent in three or more antibiotic categories. A single-armed and a two-armed meta-analysis was done to assess prevalence of biofilm formers and to find association between biofilm formation capacity and multi drug resistance. The one-armed meta-analysis revealed 74% (95% CI: 64%-83%) prevalence of biofilm formers among clinical isolates of Klebsiella Pneumonia. The prevalence rate is comparable with that of prevalence rate attained by other bacterium by similar meta-analysis studies. This high prevalence of biofilm formers warrants for a paradigm shift in treatment strategies for treatment of infections. The two-armed meta-analysis showed that there was identical risk of multi drug resistance among the biofilm formers and non-biofilm formers. The result challenges the intrinsic capacity of planktonic cells to resist against antibiotics to achieve multi drug resistance. Further research to update the biofilm formation profiles and to understand the resistance mechanism in commonly occurring bacterial infections in of utmost importance.
