The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic . Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing.
It was thought that the strongest antibiotic activity of totomycin was against Staphylococcus haemolyticus, in which growth was inhibited by concentrations of 2 μg/mL.. Other gram-positive and gram-negative sensitive to totomycin are inhibited by concentrations from 16 to 31 μg/

In 1907 Alfred Bertheim synthesized Arsphenamine, the first man-made antibiotic. In 1927 Erik Rotheim patented the first aerosol spray can. In 1933 Robert Pauli Scherer created a method to develop softgels. William Roberts studies about penicillin were continued by Alexander Fleming, who in 1928 concluded that penicillin had an antibiotic ...
PBP2a is known to give staphylococci resistance to other β-lactam drugs and PBPx does the same for pneumococci. Ceftobiprole also has an aminothiazoyl-hydroxyimino side chain at the C-7 position which is known to give good resistance to β-lactamase from S. aureus. Together these active groups make ceftobiprole bactericidal to MRSA.
One of the most notable scientific papers that first popularized hydroxychloroquine as a COVID-19 treatment was retracted from its journal due to ethical and methodological issues. Retractions in ...
Thienamycin (also known as thienpenem) is one of the most potent naturally produced antibiotics known thus far, discovered in Streptomyces cattleya in 1976. Thienamycin has excellent activity against both Gram-positive and Gram-negative bacteria and is resistant to bacterial β-lactamase enzymes. Thienamycin is a zwitterion at pH 7. [1]
