Aerobic Gram-positive cocci, including some members of the Staphylococcus and Streptococcus (e.g. pneumococcus) genera, but not enterococci. [24] Anaerobic, Gram-negative rod-shaped bacteria, including some Bacteroides, Fusobacterium, and Prevotella, although resistance is increasing in Bacteroides fragilis. [25]
Lincosamides are used against Gram-positive bacteria since they are unable to pass through the porins of Gram-negative bacteria. Clindamycin, a commonly used lincosamide, binds the 50s subunit and causes steric hindrance which inhibits the transfer of amino acids to the longer polypeptide chain. [12]
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 ...
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 ...
Detailedly, broad-spectrum antibiotics can kill or inhibit a wide range of microorganisms; extended-spectrum antibiotic can kill or inhibit Gram positive bacteria and some Gram negative bacteria; narrow-spectrum antibiotic can only kill or inhibit limited species of bacteria. [1] [2] [3]
Aminoglycoside antibiotics display bactericidal activity against Gram-negative aerobes and some anaerobic bacilli where resistance has not yet arisen but generally not against Gram-positive and anaerobic Gram-negative bacteria. [3] Streptomycin is the first-in-class aminoglycoside antibiotic.
It is particularly effective against gram-positive bacteria — such as Staphylococcus, Streptococcus, and Clostridium species — but can also treat some gram-negative bacterial infections.
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
