S sensitive, I intermediate, R resistant based on Clinical and Laboratory Standards Institute (CLSI) and the European Committee for Antimicrobial Susceptibility Testing (EUCAST) guidelines. Percent (%) resistance was calculated using following formula = total no. of antibiotics marked with R for each strain/total no. of test antibiotics × 100.
