Novel Class 1 Integrons in Multi-drug Resistant Isolates from Eastern China [PDF]

Indian Journal of Microbiology, 2013
Integrons are mobile genetic elements able to capture, express and excise resistance genes, playing an important role in the spread of bacterial resistance. The present study was to investigate the occurrence and diversity of integrons in 120 clinical multi-drug resistant Gram-negative isolates from eastern China.

Molecular Screening and Antibiogram Profile of Multidrug‐Resistant Enteropathogenic Escherichia coli Isolated From Retail Chicken Meat

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Multidrug‐resistant enteropathogenic Escherichia coli (MDR‐EPEC) were investigated in retail chicken meat from Bangladesh. Molecular confirmation, antibiogram profiling, and resistance gene detection revealed universal multidrug resistance with high MAR indices, indicating intense antimicrobial pressure and highlighting significant food safety and ...

The Evolution of Class 1 Integrons and the Rise of Antibiotic Resistance [PDF]

Journal of Bacteriology, 2008
ABSTRACTClass 1 integrons are central players in the worldwide problem of antibiotic resistance, because they can capture and express diverse resistance genes. In addition, they are often embedded in promiscuous plasmids and transposons, facilitating their lateral transfer into a wide range of pathogens.
