Diagram depicting antibiotic resistance through alteration of the antibiotic's target site, modeled after MRSA's resistance to penicillin. Beta-lactam antibiotics permanently inactivate PBP enzymes, which are essential for cell wall synthesis and thus for bacterial life, by permanently binding to their active sites. Some forms of MRSA, however ...
The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
One of the most commonly known examples of both antimicrobial resistance and the relationship to the classification of a drug of last resort is the emergence of Staphylococcus aureus (MRSA) (sometimes also referred to as multiple-drug resistant S. aureus due to resistance to non-penicillin antibiotics that some strains of S. aureus have shown ...
Clindamycin may be useful in skin and soft tissue infections caused by methicillin-resistant Staphylococcus aureus (MRSA). [7] Many strains of MRSA are still susceptible to clindamycin; however, in the United States spreading from the West Coast eastwards, MRSA is becoming increasingly resistant.

Indicated for complicated skin/skin structure infections, soft tissue infections and complicated intra-abdominal infections. Effective for gram-positive, gram-negative, anaerobic, and against multi-antibiotic resistant bacteria (such as Staphylococcus aureus [MRSA] and Acinetobacter baumannii), but not effective for Pseudomonas spp. and Proteus ...
The two antimicrobial disks contain erythromycin and clindamycin and are placed 25 mm apart when testing Staphylococcus and 15 mm apart for Streptococcus. This is called a D-zone test , or D test . If a 'D' shape is formed around the clindamycin disk (distinguished from a circular zone of inhibition) then the isolate is reported as resistant to ...
Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. [9] [10] Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA).
Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
