  2. Carbapenem-resistant enterobacteriaceae - Wikipedia

    en.wikipedia.org/wiki/Carbapenem-resistant_enter...

    In general, carbapenem, a β-lactam antibiotic, targets cells by inhibiting transpeptidases (penicillin-binding proteins). This prevents synthesis of peptidoglycan, a necessary structural component, leading to cell lysis. Resistance to carbapenem among Enterobacteriaceae and other gram-negative bacteria can be acquired through several mechanisms.

  3. Carbapenem - Wikipedia

    en.wikipedia.org/wiki/Carbapenem

    The spectrum of activity of the carbapenems against gram-positive bacteria is fairly broad, but not as exceptionally so as in the case of gram-negative bacteria. Good activity is seen against methicillin-sensitive strains of Staphylococcus species, but many other antibiotics provide coverage for such infections.

  4. β-Lactam antibiotic - Wikipedia

    en.wikipedia.org/wiki/Β-Lactam_antibiotic

    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.

  5. Meropenem - Wikipedia

    en.wikipedia.org/wiki/Meropenem

    The spectrum of action includes many Gram-positive and Gram-negative bacteria (including Pseudomonas) and anaerobic bacteria. The overall spectrum is similar to that of imipenem, although meropenem is more active against Enterobacteriaceae and less active against Gram-positive bacteria. Meropenem is effective against bacteria producing extended ...

    en.wikipedia.org/wiki/Enterobacteriaceae

    Enterobacteriaceae is a large family of Gram-negative bacteria.It includes over 30 genera and more than 100 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacterales of the class Gammaproteobacteria in the phylum Pseudomonadota.

    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 ...

  9. Beta-lactamase - Wikipedia

    en.wikipedia.org/wiki/Beta-lactamase

    Among gram-negative bacteria, the emergence of resistance to extended-spectrum cephalosporins has been a major concern. It appeared initially in a limited number of bacterial species (E. cloacae, C. freundii, S. marcescens, and P. aeruginosa) that could mutate to hyperproduce their chromosomal class C β-lactamase.
