Antibiotics and their different application strategies in controlling the biofilm forming pathogenic bacteria
Fazlurrahman Khan, Dung T N Pham, Sandra Oloketuyi, Young-Mog Kim, 2020, pregledni znanstveni članek

Opis: Background: The establishment of a biofilm by most pathogenic bacteria has been known as one of the resistance mechanisms against antibiotics. A biofilm is a structural component where the bacterial community adheres to the biotic or abiotic surfaces by the help of Extracellular Polymeric Substances (EPS) produced by bacterial cells. The biofilm matrix possesses the ability to resist several adverse environmental factors, including the effect of antibiotics. Therefore, the resistance of bacterial biofilm-forming cells could be increased up to 1000 times than the planktonic cells, hence requiring a significantly high concentration of antibiotics for treatment. Methods: Up to the present, several methodologies employing antibiotics as an anti-biofilm, antivirulence or quorum quenching agent have been developed for biofilm inhibition and eradication of a pre-formed mature biofilm. Results: Among the anti-biofilm strategies being tested, the sub-minimal inhibitory concentration of several antibiotics either alone or in combination has been shown to inhibit biofilm formation and down-regulate the production of virulence factors. The combinatorial strategies include (1) combination of multiple antibiotics, (2) combination of antibiotics with non-antibiotic agents and (3) loading of antibiotics onto a carrier. Conclusion: The present review paper describes the role of several antibiotics as biofilm inhibitors and also the alternative strategies adopted for applications in eradicating and inhibiting the formation of biofilm by pathogenic bacteria.

Antimicrobial susceptibility profile of airborne bacteria and fungi at Owena Market, Osun State, Nigeria
Gbenga Folorunsho Oginni, Sandra Oloketuyi, Olufunke Chukwu, Janet Odunayo, 2017, izvirni znanstveni članek

Opis: Environmental conditions and human activities influence the ubiquity and diversity of microorganisms in the atmosphere thereby acquiring the ability to resist antibiotics which poses serious public threat. Airborne bacteria and fungi isolated using settling plate method from three different points (where kolanuts, meat and onions are sold) at Owena Market, Osun state, Nigeria were assayed for antimicrobial susceptibility using disc diffusion. The microorganisms were identified as Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Proteus vulgaris, Bacillus megaterium, Alcaligenes spp., Aeromonas spp., Escherichia coli, Micrococcus spp., Streptococcus spp., Mortierella polycephala, Epicoccum nigrum, Alternaria spp., Penicillium chrysogenum, Aspergillus flavus, Acremonium spp., Penicillium oxalicum, Cladosporium cladosporiodes, Rhizopus stolonifer, Stemphylium spp., and Trichoderma spp. About 30% of the bacterial isolates were resistant to the antibacterial agents (antibiotics) and all the bacterial isolates were resistant to at least four or more antibiotics while 18% and 64% of the fungi isolated were susceptible to griseofulvin and ketoconazole, respectively. This study shows that the market environment serves as reservoirs for multiple antibiotic resistant bacteria and fungi capable of causing infectious diseases.
