some bacterial cells are resistant to a variety of antimicrobials?
449770
Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell. ... Resistant cells grow more efficiently and quickly than susceptible cells. β-lactamase production is an example of which of the following types of resistance?

Why are gram positive bacteria typically mre resistant than gram negative bacteria to antibiotics, that disrupt plasma membranes, such as polymyxin B? ... Gram positives are more resistant to this drug because their thick cell wall protects then when they take on water.

Broad-spectrum (antipseudomonal) penicillin aureus, E. coli, K. pneumoniae, H. influenzae, and gram-negative anaerobic bacilli, but not against gram-negative bacilli that produce AmpC beta-lactamase, and may only partially inhibit ESBL produced by some K.

Most Gram-negative bacteria are intrinsically resistant to vancomycin because their outer membranes are impermeable to large glycopeptide molecules (with the exception of some non-gonococcal Neisseria species).

Broad-spectrum antibiotics (e.g., penicillins, aminoglycosides, cephalosporins, sulfonamides) work against a wide range of bacterial infections. Narrow-spectrum antibiotics (e.g., macrolides, vancomycin, fidaxomicin) are only effective against a few types of pathogenic bacteria.

Gram-negative bacteria are more resistant to antibodies and antibiotics than Gram-positive bacteria, because they have a largely impermeable cell wall.
597507
Gram-negative bacteria are generally less susceptible to disinfectants than gram-positive bacteria, presumably due to the reduced permeability of the double membrane. Mutants of various bacterial species (S.

Antibiotics are medicines used to prevent and treat bacterial infections. ... Antimicrobial resistance is a broader term, encompassing resistance to drugs to treat infections caused by other microbes as well, such as parasites (e.g. malaria), viruses (e.g. HIV) and fungi (e.g. Candida).

These infections can occur anywhere in the body. Some common sites include the intestines, the urinary tract, and wounds. Vancomycin-resistant enterococci infections are treated with antibiotics, which are the types of medicines normally used to kill bacteria.

aeruginosa to most antimicrobials tested, including ceftazidime (79.6/68.7 % susceptibility in USA/Europe), meropenem (76.3/65.8 %), and piperacillin/tazobactam (72.9/63.9 %).

The use of different types of antibiotics over the years has led to the emergence of multi-resistant MRSA strains2, the result of mutations in genes coding for target proteins and through the acquisition and accumulation of antibiotic resistance-conferring genes.

Staphylococcus aureus is notorious for its ability to become resistant to antibiotics. Infections caused by antibiotic-resistant strains often occur in epidemic waves initiated by one or a few successful clones. Methicillin-resistant S. aureus (MRSA) is prominently featured during these epidemics.
1398055
MRSA, which most everyone knows about now, is gram-positive. We know about MRSA, but there has been an increase in infections caused by gram-negative bacteria, and they are resistant to many, or sometimes all, drugs.

Antibacterial Technologies: Antibacterial technologies are effective against a broad spectrum of harmful bacteria including E. coli and MRSA. ... Antimicrobial Technologies: Antimicrobial technologies minimise the presence of bacteria, mold, and fungi.

Antibiotics are medicines used to prevent and treat bacterial infections. Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans, become antibiotic resistant.
