Emerging antibiotic resistance in bacteria with special reference to India

Area of Science:

• Microbiology
• Epidemiology
• Public Health

Background:

• The antibiotic era, beginning in the 1940s, revolutionized infectious disease treatment but was soon followed by bacterial antibiotic resistance.
• Extensive research has elucidated diverse resistance mechanisms and their genetic basis, revealing the resilience of prokaryotic ecosystems to antibiotic stress.

Purpose of the Study:

• To provide an overview of the global antimicrobial resistance landscape.
• To examine the epidemiology of antibiotic resistance, including community practices and the impact of high usage environments.
• To specifically review the antimicrobial resistance situation in India and identify contributing factors.

Main Methods:

• Literature review and synthesis of existing data on antibiotic resistance.
• Epidemiological analysis of antibiotic resistance patterns globally and within India.
• Discussion of factors influencing antibiotic resistance, including usage in human and animal health.

Main Results:

• Antibiotic resistance has emerged as a significant challenge, with increasing rates observed globally.
• High antibiotic usage in both community settings and animal agriculture contributes to resistance.
• India exhibits high rates of antibiotic resistance among major pathogens, influenced by specific local factors.

Conclusions:

• The increasing trend of antibiotic resistance, coupled with a decline in new antibiotic development, suggests a potential post-antibiotic era.
• Urgent research is needed to ensure the continued efficacy of antibiotics in controlling infectious diseases.
• Understanding and addressing the factors driving resistance, particularly in regions like India, is crucial for future antimicrobial stewardship.
