Abstract:
A major threat to the world is the emergence of antibiotic resistant bacteria, which has rendered previously susceptible drugs useless and increased the rate of therapeutic failures. Shigella species, which are the causative organism of Shigellosis, were earlier susceptible to ampicillin, chloramphenicol, co-trimoxazole and nalidixic acid but now they have developed resistance against fluoroquinolones, cephalosporins and azithromycin. Many shigellosis outbreaks have been reported by resistant strains of Shigella species. This review attempts to provide a brief overview about the scenario of shigellosis and the emergence as well as ubiquitous nature of multidrug resistant (MDR) Shigella species.
Insights
Antibiotic resistance is a global threat. This review highlights the rise of multidrug-resistant Shigella species, causing widespread shigellosis outbreaks and treatment failures.
Area of Science:
- Microbiology
- Infectious Diseases
- Antimicrobial Resistance
Background:
- Antibiotic resistant bacteria pose a significant global health threat.
- Shigella species, the cause of shigellosis, are increasingly resistant to common antibiotics.
- This resistance leads to higher rates of treatment failure and outbreaks.
Purpose of the Study:
- To review the current situation of shigellosis.
- To examine the emergence and widespread nature of multidrug-resistant (MDR) Shigella species.
- To understand the impact of antimicrobial resistance on Shigella infections.
Main Methods:
- Literature review of published studies on Shigella and antibiotic resistance.
- Analysis of reported outbreaks and resistance patterns.
- Synthesis of data on susceptibility trends of Shigella species.
Main Results:
- Shigella has developed resistance to formerly effective drugs like ampicillin and nalidixic acid.
- Emerging resistance is observed against fluoroquinolones, cephalosporins, and azithromycin.
- Numerous outbreaks of shigellosis are attributed to resistant Shigella strains.
Conclusions:
- Multidrug-resistant Shigella species represent a growing public health concern.
- The ubiquitous nature of MDR Shigella necessitates urgent surveillance and control strategies.
- Understanding resistance patterns is crucial for effective shigellosis management.
