Anaerobic, Gram-negative rod-shaped bacteria, including some Bacteroides, Fusobacterium, and Prevotella, although resistance is increasing in Bacteroides fragilis. [ 25 ] Most aerobic Gram-negative bacteria (such as Pseudomonas , Legionella , Haemophilus influenzae and Moraxella ) are resistant to clindamycin, [ 24 ] [ 26 ] as are the ...
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]
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.
Gram-negative, Gram-positive, anaerobes: Rarely: aplastic anemia. Inhibits bacterial protein synthesis by binding to the 50S subunit of the ribosome Fosfomycin: Monurol, Monuril: Acute cystitis in women: This antibiotic is not recommended for children and 75 and up of age: Inactivates enolpyruvyl transferase, thereby blocking cell wall ...
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]
Antibiotic macrolides are used to treat infections caused by Gram-positive bacteria (e.g., Streptococcus pneumoniae) and limited Gram-negative bacteria (e.g., Bordetella pertussis, Haemophilus influenzae), and some respiratory tract and soft-tissue infections. [4]
Lincomycin is a narrow spectrum antibiotic with activity against Gram-positive and cell wall-less bacteria including pathogenic species of Streptococcus, Staphylococcus, and Mycoplasma. [7] Lincomycin is used to treat severe bacterial infections in patients who cannot use penicillin antibiotics.
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 ...
