The discovery of antibiotics has revolutionized medical treatment by reducing mortality caused by pathogens, but indiscriminate use has targeted multiresistant microorganisms that can generate aggressive outbreaks of nosocomial infections. In addition, the decrease in investments by the pharmaceutical industry for the discovery of new antibiotics resulted in a lower production rate than the increase in antimicrobial resistance, justifying the need to discover new drugs. A group of bacteria responsible for most hospital infections, called ESKAPE, Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp. also have the ability to "escape" the action of multiple antibiotics. The objective of the Laboratory of Epidemiology and Molecular Microbiology (LEMiMo) is to find possible drugs from compounds / extracts sent by other members of the Center for Innovation in Biodiversity and Drug Discovery (CIBFar), one of the CEPIDs of FAPESP. This project aims to evaluate the antimicrobial action of new compounds (plant extracts, natural products, peptides, etc.) against several ESKAPE bacteria of clinical origin. In addition, the same compounds will be evaluated for the ability to eradicate biofilm formed by a strain of Staphylococcus epidermidis. After screening, minimum inhibitory concentration and minimum bactericidal concentration will be determined. All compounds will be submitted to the biofilm eradication test. (AU)
