Enterobacter encompasses a family of Gram-negative, rod-shaped (bacillus) species of bacteria. Some strains cause urinary tract (UTI) and blood infections and are resistant to multiple drug therapies, which therefore puts the human population in critical need for the development of novel and effective antibiotic treatments.[15] Colistin and tigecycline are two of the only antibiotics currently used for treatment, and there are seemingly no other viable antibiotics in development.[2] In some Enterobacter species, a 5- 300 fold increase in minimum inhibitory concentration was observed when exposed to several gradually increasing concentrations of benzalkonium chloride (BAC).[16] Other Gram-negative bacterias (including Enterobacter, but also Acinetobacter, Pseudomonas, Klebsiella species, and more) also displayed a similar ability to adapt to the disinfectant BAC.[16]
