Multiple antibiotic resistance indices and multiple drug resistance patterns of bacterial isolates.

Bacterial strains	Antibiotic(s) to which the bacterial isolate was resistant to	MDR pattern	MAR index
Micrococcus spp.	COT	No	0.1
Salmonella enteritidis	AMP and COT	No	0.3
Escherichia coli	AMP and COT	No	0.3
Aeromonas hydrophila	AMP, TET, and COT	Yes	0.4
