Resistogram typing of Shigella flexneri
Summary
Fifty Shigella flexneri strains showed varied resistance to antibacterial drugs. Resistograms created from these results correlated well with bacterial serotyping, aiding in understanding dysentery causes.
Area of Science:
- Microbiology
- Infectious Diseases
- Bacteriology
Background:
- Bacillary dysentery, caused by Shigella flexneri, remains a significant public health concern.
- Understanding antimicrobial resistance patterns is crucial for effective treatment and disease control.
Purpose of the Study:
- To assess the antimicrobial resistance profiles of Shigella flexneri strains isolated from sporadic cases of bacillary dysentery.
- To evaluate the utility of resistograms in characterizing bacterial strains and their correlation with serotyping.
Main Methods:
- Fifty Shigella flexneri strains were isolated from patients with bacillary dysentery.
- Antimicrobial susceptibility testing was performed using seven different antibacterial compounds.
- Resistograms were generated based on the observed resistance patterns and compared with serotyping results.
Main Results:
- Significant variations in resistance to the tested antibacterial compounds were observed among the Shigella flexneri strains.
- Sixteen distinct resistogram patterns were identified.
- The generated resistograms demonstrated a strong correlation with the established serotyping classifications of the bacteria.
Conclusions:
- Antimicrobial resistance is a notable characteristic of the studied Shigella flexneri strains.
- Resistogram analysis provides a valuable and consistent method for bacterial strain differentiation, complementing traditional serotyping techniques in the study of bacillary dysentery.
