Antibiotic resistant bacteriaare strains of bacteria that do not respond to antibiotics. Instances of antibiotic resistance bacteria may occur on an individual basis or on a much larger scale. We'll touch on both. Imagine that you are sick and your doctor has confirmed that bacteria are to blam...
Antibiotic resistance, loss of susceptibility of bacteria to the killing (bacteriocidal) or growth-inhibiting (bacteriostatic) properties of an antibiotic agent. When a resistant strain of bacteria is the dominant strain in an infection, the infection ma
Gram-positive bacterium, any of various types of bacteria that are characterized by having a thick peptidoglycan cell wall and by the absence of an outer membrane composed of lipopolysaccharide. Gram-positive bacteria are named because of their reaction
An example of how antibiotic resistance spreads is when animals get an antibiotic and develop drug-resistant bacteria in the gut. Microbial resistance now global threat The experts pointed out that there was a dire need to encourage best practices among the general public, health workers and policy...

Means by which bacteria become resistant to antibiotics; Mechanisms by which resistant bacteria spread; Role of physicians in spreading antibiotic resistance; Gram-positive and gram-negative bacteria; Mycobacterium ...
"The first big cost of antibiotics is resistance," he says. "But the other side of the coin is [the fact that] antibiotics are extinguishing our microbiome and changing human development." By that, Blaser is referring to growing research that shows that the trillions of bacteria that live ...

The worldwide emergence of antibiotic resistance poses a serious threat to human health. A molecular understanding of resistance strategies employed by bacteria is obligatory to generate less-susceptible antibiotics. Albicidin is a highly potent antibact
