Enterobacterial Repetitive Intergenic Sequences

Enterobacterial repetitive intergenic sequences represent genomic elements enabling bacterial strain differentiation through DNA fingerprinting. Polymerase chain reaction amplification generates strain-specific banding patterns. Typing distinguishes epidemic from endemic contamination sources. Nosocomial infection investigation employs typing confirming contamination source.

Pharmaceutical environmental monitoring programmes employ typing when contamination isolation identification proves necessary. Regulatory inspections may request typing data following significant contamination incidents. Emerging next-generation sequencing approaches provide genomic typing superior to traditional methods. Infection control programmes employ typing guiding decontamination targeting.
