Antimicrobial drug resistance against Escherichia coli and its harmful effect on animal health.

Multidrug resistance among pathogenic bacteria is imperilling the worth of antibiotic infection, which has become an emerging problem, which previously transformed the veterinary sciences. Since its discovery, many antibiotics have been effective in treating bacterial infections in animals. Escherichia coli, a bacterium, is one of the reservoirs of antibiotic resistance genes in a community. The current use of antibiotics and demographic factors usually increase multidrug resistance. Genetically, the continuous adoption of environmental changes by E. coli allows it to acquire many multidrug resistance. During the host's life, antimicrobial resistance rarely poses a threat to the E. coli strain and pressure, similar to that of a flexible animal lower intestine. In this review, we describe the E. coli antibiotic drug-resistance mechanism driving transmission, the causes of transmission and the harmful effects on animal health.
