6- antibiotic resistance Flashcards
antibiotic resistance
Bacteria evolve to become resistant to the effects of antibiotics.
antibiotic resistance mechanism
• Antibiotic resistance develops through the process of natural selection.
• Exposure to an antibiotic kills susceptible bacteria, but some bacteria may have mutations that allow them to survive the antibiotic.
• These resistant bacteria reproduce, passing on their resistance to their offspring.
antibiotic resistance spread
Resistant bacteria can spread within a population, between individuals, and even between species. They can share resistance genes with other bacteria through horizontal gene transfer.
factors contributing to antibiotic resistance
- overuse of antibiotics
- agricultural use
- global travel and trade
factors contributing to antibiotic resistance- overuse of antibiotics
When antibiotics are used excessively or incorrectly (for viral infections or not completing the full course), it provides more opportunities for bacteria to evolve resistance.
factors contributing to antibiotic resistance- agricultural use
The use of antibiotics in livestock can promote the development of resistance in bacterial populations.
factors contributing to antibiotic resistance- global travel and trade
These can spread resistant bacteria across geographical boundaries.
controlling the spread of antibiotic resistance
• Antibiotics usage control to prevent overuse and misuse.
• Infection control measures to prevent the transmission of antibiotic-resistant bacteria.
• Surveillance of antibiotic resistance to monitor its spread.
• Development of new antibiotics.
challenges in controlling the spread of antibiotic resistance
• Inconsistent regulations across countries regarding antibiotic use.
• Lack of awareness about antibiotic resistance in the general public.
• Economic challenges in developing new antibiotics.
• Bacteria’s ability to rapidly evolve and adapt.
