I am currently engaged in research pertaining to multidrug-resistant bacteria, including but not limited to Staphylococcus aureus, Klebsiella pneumonia, Pseudomonas aeruginosa, Enterococcus faecalis, Escherichia coli, and Bacillus cereus. My objective is to identify the three least efficacious antibiotics against these strains and, more broadly, to ascertain their general resistance patterns.
