Antibiotic Resistance

A phenomenon where bacteria evolve mechanisms to survive exposure to antibiotics that would normally kill them or inhibit their growth.

Key Facts

Bacteria become resistant when antibiotics fail to eliminate them due to genetic mutations or environmental adaptation.
Multi-drug resistant bacteria severely limit the available treatment options for veterinarians and physicians.
Resistant strains can quickly adapt to new drugs and actively evade host immune responses.

Treating bacterial infections with inappropriate antibiotics accelerates resistance development.

MRSA is defined by its historical and ongoing resistance to methicillin and related antibiotics.

MRSP demonstrates the same multi-drug resistance patterns as MRSA but in a veterinary-adapted strain.

Bacterial resistance mechanisms frequently include strategies to bypass or suppress the host immune response.
