The rapid emergence of resistant bacteria is occurring worldwide endangering the efficacy of antibiotics which have transformed medicine and saved millions of lives16Many decades after the first patients were treated with antibiotics. Antibiotic resistance happens when bacteria change and become resistant to the antibiotics used to treat the infections they cause. Over-use and misuse of antibiotics increase the development of resistant bacteria and this survey points out some of the practices gaps in understanding and misconceptions which contribute to this phenomenon.

Antibiotic resistance is ancient and the resistome is a dynamic and mounting problem. Causes of the global resistome are overpopulation enhanced global migration increased use of antibiotics in clinics and animal production selection pressure poor sanitation wildlife spread and poor sewerage disposal system12 Antibiotic treatment is one of the main approaches of. Antimicrobial resistance AMR became in the last two decades a global threat to public health systems in the world.

Since the antibiotic era with the discovery of the first antibiotics that provided consistent health benefits to human medicine the misuse and abuse of antimicrobials in veterinary and human medicine have accelerated the growing worldwide phenomenon of AMR. Responsible for intrinsic antibiotic resistance in bacteria. Antibiotic resistance can be acquired by bacteria through chromosomal mutations or via horizontal gene transfer from other bacteria.

Antibiotic resistance in bacteria can develop mainly due to three mechanisms Figure 2. I Decreased influx or increased efflux of antibiotics. Antibiotic entry into the cell is mainly through porins.

The multivariate regression model used for explaining antibiotic resistance is where the dependent variable ABRAntibiotic Resistance Rate is the rate of resistance to antibiotics measured in bacteria causing bloodstream infections i 1 2 N is the subscript representing country and t 1 2 T represents the time unit in years. 13 rows On CDCs website antibiotic resistance is also referred to as antimicrobial.
