Antimicrobial resistance

resistance of microbes to drugs directed against them

movement of genetic material between organisms other than by transmission from parent to offspring

natural genetic exchange of bacteria

species of fungus

chemical compound

a laboratory procedure in which samples of a bacterium are treated with a variety of antibiotics.

a microbial organism's resistance to multiple antimicrobial drugs or a cancer cell's resistance to multiple cytostatics

decreased susceptibility of a pest population to a pesticide that was previously effective at controlling the pest

misuse or overuse of antibiotics, with potentially serious effects on health

use of antibiotics for any purpose in the husbandry of livestock

thumb|right|Escherichia coli|E. coli, the bacterium in which MCR-1 was first identified. The mobilized colistin resistance (mcr) gene confers plasmid-mediated resistance to colistin, one of a number of last-resort antibiotics for treating Gram-negative infections. mcr-1, the original variant, is capable of horizontal transfer between different strains of a bacterial species. After discovery in November 2015 in E. coli (strain SHP45) from a pig in China it has been found in Escherichia coli, Salmonella enterica, Klebsiella pneumoniae, Enterobacter aerogenes, and Enterobacter cloacae. , it has b

thumb|321x321px Cross-resistance is when something develops resistance to several substances that have a similar mechanism of action. For example, if a certain type of bacteria develops antimicrobial resistance to one antibiotic, that bacteria will also have resistance to several other antibiotics that target the same protein or use the same route to get into the bacterium. A real example of cross-resistance occurred for nalidixic acid and ciprofloxacin, which are both quinolone antibiotics. When bacteria developed resistance to ciprofloxacin, they also developed resistance to nalidixic acid b
