HIV is the prime example of MDR against antivirals, as it mutates rapidly under monotherapy. Influenza virus has become increasingly MDR; first to amantadines, then to neuraminidase inhibitors such as oseltamivir, (2008-2009: 98.5% of Influenza A tested resistant), also more commonly in people with weak immune systems.
MDR strains of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii have become of most concern because they have been reported by hospitals all around the United States. There are many factors which could be contributed to the existence and spread of MDR gram-negative bacteria such as the: overuse or misuse of existing ...
Multidrug-resistant bacteria (MDR bacteria) are bacteria that are resistant to three or more classes of antimicrobial drugs. [1] MDR bacteria have seen an increase in prevalence in recent years [ clarification needed ] [ 2 ] and pose serious risks to public health .
Multidrug-resistant tuberculosis (MDR-TB) is a form of tuberculosis (TB) infection caused by bacteria that are resistant to treatment with at least two of the most powerful first-line anti-TB medications (drugs): isoniazid and rifampicin.
This class of antibiotics is usually reserved for known or suspected multidrug-resistant (MDR) bacterial infections. Similar to penicillins and cephalosporins , carbapenems are members of the beta-lactam antibiotics drug class, which kill bacteria by binding to penicillin-binding proteins , thus inhibiting bacterial cell wall synthesis.
P-gp is a 170 kDa transmembrane glycoprotein, which includes 10–15 kDa of N-terminal glycosylation.The N-terminal half of the protein contains six transmembrane helixes, followed by a large cytoplasmic domain with an ATP-binding site, and then a second section with six transmembrane helixes and an ATP-binding domain that shows over 65% of amino acid similarity with the first half of the ...
Classification and regression tree analysis determined a split of organism MIC between 2 and 4 mg/liter and predicted differences in mortality (16.1% for 2 mg/liter versus 76.9% for 4 mg/liter). In logistic regression controlling for confounders, each imipenem MIC doubling dilution doubled the probability of death.
MDR pumps in the cell membrane extrudes many foreign substances out of the cells and some pumps can have a broad specificity. [1] MDR pumps exist in animals, fungi, and bacteria and likely evolved as a defense mechanism against harmful substances. There are seven families of MDRs and are grouped by homology, energy source, and overall structure ...
