Abstract:
As recently indiscriminate abuse of existing antibiotics in both clinical and veterinary treatment leads to proliferation of antibiotic resistance in microbes and poses a dilemma for the future treatment of such bacterial infection, antimicrobial resistance has been considered to be one of the currently leading concerns in global public health, and reported to widely spread and extended to a large variety of microorganisms. In China, as one of the currently worst areas for antibiotics abuse, the annual prescription of antibiotics, including both clinical and veterinary treatment, has approaching 140 gram per person and been roughly estimated to be 10 times higher than that in the United Kingdom, which is considered to be a potential area for the emergence of "Super Bugs". Based on the integrons surveillance in Guangzhou, China in the past decade, this review thus aimed at summarizing the role of integrons in the perspective of both clinical setting and environment, with the focus on the occurrence and prevalence of class 1, 2 and 3 integrons.
Insights
Antibiotic resistance is a global health crisis. This review examines integrons in China, highlighting their role in the spread of "Super Bugs" due to widespread antibiotic misuse.
Area of Science:
- Microbiology
- Public Health
- Environmental Science
Background:
- Indiscriminate antibiotic use in clinical and veterinary settings drives microbial antibiotic resistance, a major global public health concern.
- China faces a severe antibiotic abuse problem, with prescriptions significantly higher than in the UK, creating a hotspot for "Super Bug" emergence.
- Antimicrobial resistance is spreading widely across diverse microorganisms, complicating future bacterial infection treatments.
Purpose of the Study:
- To review the role of integrons in the clinical and environmental settings.
- To focus on the occurrence and prevalence of class 1, 2, and 3 integrons in Guangzhou, China.
- To understand the contribution of integrons to the proliferation of antibiotic resistance.
Main Methods:
- Integron surveillance data from Guangzhou, China, over the past decade.
- Review of existing literature on integron prevalence and function.
- Analysis of antibiotic resistance patterns linked to integron carriage.
Main Results:
- Class 1, 2, and 3 integrons are prevalent in both clinical and environmental samples in Guangzhou.
- Integrons are key drivers in the dissemination of antibiotic resistance genes.
- High rates of antibiotic abuse correlate with increased integron prevalence.
Conclusions:
- Integrons play a critical role in the spread of antimicrobial resistance in China.
- Effective strategies to curb antibiotic abuse are essential to control integron-mediated resistance.
- Continued surveillance of integrons is crucial for public health protection.
