  2. Virulence factor - Wikipedia

    en.wikipedia.org/wiki/Virulence_factor

    Virulence factors (preferably known as pathogenicity factors or effectors in botany) are cellular structures, molecules and regulatory systems that enable microbial pathogens (bacteria, viruses, fungi, and protozoa) to achieve the following: [1] [2]

  3. Antimicrobial resistance - Wikipedia

    en.wikipedia.org/wiki/Antimicrobial_resistance

    Antimicrobial resistance (AMR or AR) occurs when microbes evolve mechanisms that protect them from antimicrobials, which are drugs used to treat infections. [2] This resistance affects all classes of microbes, including bacteria (antibiotic resistance), viruses (antiviral resistance), protozoa (antiprotozoal resistance), and fungi (antifungal ...

  4. Antimicrobial - Wikipedia

    en.wikipedia.org/wiki/Antimicrobial

    Antimicrobial use has been common practice for at least 2000 years. Ancient Egyptians and ancient Greeks used specific molds and plant extracts to treat infection. [5]In the 19th century, microbiologists such as Louis Pasteur and Jules Francois Joubert observed antagonism between some bacteria and discussed the merits of controlling these interactions in medicine. [6]

  5. Antibiotic - Wikipedia

    en.wikipedia.org/wiki/Antibiotic

    An antibiotic is a type of antimicrobial substance active against bacteria.It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections.

  6. Medical microbiology - Wikipedia

    en.wikipedia.org/wiki/Medical_microbiology

    Antimicrobial resistance is an increasingly problematic issue that leads to millions of deaths every year. [41] Whilst drug resistance typically involves microbes chemically inactivating an antimicrobial drug or a cell mechanically stopping the uptake of a drug, another form of drug resistance can arise from the formation of biofilms.

  7. M protein (Streptococcus) - Wikipedia

    en.wikipedia.org/wiki/M_protein_(Streptococcus)

    M protein is strongly anti-phagocytic and is the major virulence factor for group A streptococci (Streptococcus pyogenes). It binds to serum factor H, destroying C3-convertase and preventing opsonization by C3b. However plasma B cells can generate antibodies against M protein which will help in opsonization and further the destruction of the ...

  8. List of antibiotic-resistant bacteria - Wikipedia

    en.wikipedia.org/wiki/List_of_antibiotic...

    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. Bacteriocin - Wikipedia

    en.wikipedia.org/wiki/Bacteriocin

    There are several strategies by which new bacteriocins can be discovered. In the past, bacteriocins had to be identified by intensive culture-based screening for antimicrobial activity against suitable targets and subsequently purified using fastidious methods prior to testing. However, since the advent of the genomic era, the availability of ...
