Origins and kinds of Antibiotic and Antimicrobials
The world is within the midst of an emerging crisis of antibiotic resistance to microbial pathogens. Numerous pathogens that became immune to commonly used antibiotics are described in various contexts, including drug-resistant methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pneumonia, and tubercle bacillus .
