<prompt> A person with prolonged usage of contact lenses presented with irritation of the left eye. After examination a diagnosis of keratitis was made and corneal scrapings revealed the growth of pseudomonas aeruginosa. The bacteria were observed to be multidrug resistant. Which of the following best explains the mechanism of antimicrobial resistance in these isolated pseudomonas aeruginosa strainsAbility to transfer resistance genes from adjacent commonsal floraImproper contact lens hygieneFrequent and injudicious use of topical antibioticsAbility of pseudomonas to produce biofilms  <response>: Antibiotic resistance to Pseudomonas Aeroginosa strains from contact lens wearer largely results from the ability of these strains to form slime enclosed microcolonies or biofilms.Biofilm grown cells show increased resistance to biocides and antibiotics through multiple resistance mechanisms.
