Abstract

BACKGROUNDDiabetes mellitus (DM) is a serious health problem that is rapidly expanding worldwide. Staphylococcus aureus is a pathogenic bacterium which has a number of drug resistant strains. Different variants of this pathogen have been isolated from patients with diabetic foot ulcers - in persons having uncontrolled blood sugar level - all over the world, resulting in high rates of morbidity and mortality. The objective of this study was to determine the prevalence of drug resistant Staphylococcus aureus in diabetic foot infections (DFIs). METHODS An epidemiological survey was conducted and 300 pus samples were collected from wounds, abscesses, skin and soft tissue lesions of patients having type II diabetes with foot ulcer infections at a tertiary care hospital. Further, the antibacterial susceptibility patterns of all the isolated Staphylococcus aureus were determined against methicillin, oxacillin, vancomycin and novobiocin. RESULTS Pathogenic bacterial species including coagulase positive and coagulase negative Staphylococcus aureus, Escherichia coli, Klebsiella sp., Proteus sp., Pseudomonas sp., and Citrobacter sp. were identified, among which Staphylococcus was the main genus identified. A total of 13 (4.3%) isolates of coagulase positive Staphylococcus aureus were resistant to methicillin. Using PCR, 7 (53.8%) staphylococcal isolates were detected with the mecA gene. CONCLUSIONStaphylococcus aureus is the most common cause of DFIs. This study demonstrates that about 53.8% of all methicillin resistant Staphylococcus aureus isolates have mecA genes. Such a finding is the primary step in understanding and tackling the resistance mechanism.

Abstract

BackgroundUrinary tract infections are often initiated by indwelling catheters and bring about serious consequences, especially when they are caused by multidrug-resistant bacterial pathogens. The biofilms of uropathogens such as Enterococcus faecalis and Escherichia coli pose serious challenges. Therefore the scientific world is trying to experiment with alternative drugs to replace conventional antibiotics as the latter are more prone to cause the development of antibacterial resistance. Here, we evaluate the repurposing of the antidepressant fluoxetine as an antibacterial agent against the mentioned pathogens. MethodsTo repurpose fluoxetine for its antibacterial activity against Enterococcus faecalis and Escherichia coli, the agar diffusion method was used. The minimal inhibitory concentration was found by the microdilution method. The drug was also analyzed as a coating on catheters to evaluate its efficiency against biofilm formation by pathogens. Results The drug fluoxetine showed potential antibacterial and anti-biofilm activities. Its minimum inhibitory concentration was found to be 18.75 µg/mL and 37.5 µg/mL against Enterococcus faecalis and Escherichia coli respectively. The antibiofilm activity on polystyrene surfaces was also remarkable as it reduced the formation of Enterococcus faecalis and Escherichia coli biofilms by 70% and 74%, after being treated with 1x MICs and 2x MICs respectively. Conclusions Fluoxetine - one of the drugs of choice in treating depression, when repurposed, has shown considerable antibacterial and antibiofilm effects against two of the major catheter-associated urinary tract infection-causing bacteria - viz. Enterococcus faecalis and Escherichia coli. Therefore, further studies are needed to understand its applicability as an antibacterial agent.
