Resistance mechanisms to antibiotics exist that render cells "immune" to the antibiotic; the genes for these characteristics are found in certain organisms. The genes are used in some genetic engineering experiments as tools to identify cells that have received new DNA.
Occurs when bacteria or other microbes that cause disease evolve into forms that can no longer be killed by antibiotics. It is the reason people are not given antibiotics as readily as in the past.
Antibiotics are used in medicine due to their capability of inhibiting or neutralising alien agents that enter the human body. Antibiotics are naturally produced by organisms as a means of defense and hence survival. Through natural selection, organisms that fall prey to antibiotics begin to develop a resistance, and the effects of the antibiotics diminish over time until the organisms are immune to its effect.
The ability acquired by microorganisms to defend themselves against antibiotics. The recent overuse and misuse of antibiotics have rendered many antibiotics useless against various strains of foodborne illness including Salmonella, Campylobacter, Staphylococcus and Streptococcus.
The tendency for a bacteria to develop a resistance to one or more antibiotics. This can occur when antibiotics are used repetitively. Most targeted bacteria are killed by a dose of antibiotics, but some are not. These remaining bacteria have a genetic resistance to the antibiotic, and this trait can be passed on to their offspring. For this reason there is a push to reduce the unnecessary use of antibiotics, or else they will be rendered ineffective in the treatment of certain diseases. Australia New Zealand Food Authority (ANZFA) - The body responsible for developing, varying and reviewing standards for food available in Australia and New Zealand. They also coordinate national food surveillance and recall systems, conduct research, assess policies about imported food and develop codes of practice with industry.
The ability of a bacterium to resist or overcome the effects of an antibiotic.
The ability of bacteria to tolerate antibiotics and remain unaffected by them. Resistance may evolve naturally in bacteria after years of exposure to antibiotics. It is controlled by genes and can be spread between bacteria. Many medically important bacteria have become resistant to one or more antibiotic drugs. Bacteria that have resistance to many different antibiotics are a major medical worry as they may result in infections that are untreatable.
The ability of bacteria to tolerate an antibiotic and survive being exposed to it. Bacteria may develop this resistance naturally after being exposed to it over many years.
The percentage of Priority Health children members with ear infections, in the Primary Care Provider's (PCP) practice group, who were treated with first-level antibiotics or no antibiotics. Proper treatment of ear infections can lessen long-term resistance to antibiotics.
When a cell becomes tolerant to an antibiotic that it previously had the ability to destroy.
a property of bacteria that confers the capacity to inactivate or exclude antibiotics or a mechanism that blocks the inhibitory or killing effects of antibiotics.
The ability of some bacterium to live in the presence of lethal doses of antibiotics.
Frequent exposure to an antibiotic provides conditions favorable to the evolution of germs, which are resistant to (i.e. not harmed by) that antibiotic.
Tendency of certain bacteria to develop a resistance to commonly over-used antibiotics.
a condition where micro-organisms continue to multiply although exposed to antibiotic agents, often because the bacteria has become immune to the medication. Overuse or inappropriate use of antibiotics leads to antibiotic resistance.
the ability of micro organisisms/microbes to stop antibiotics from working
Bacteria's ability to mutate in order to survive treatment with antibiotics. Over time, bacteria are able to change their characteristics so that antibiotics cannot kill them. This process happens faster when antibiotics are used very frequently, especially at low doses over long periods of time, which is common on factory farms where antibiotics are added to feed.
the development by bacteria of the ability to live in the presence of a certain antibiotic, making treatment difficult
heritable trait in microorganisms that enables them to survive in the presence of an antibiotic.
that state which results when an antibiotic is no longer effective or as effective in inhibiting or killing bacteria.
Antibiotic resistance is the ability of a micro-organism to withstand the effects of an antibiotic. It is a specific type of drug resistance. Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered for the purpose of creating bio-weapons.
