What were the major regional trends in antibacterial susceptibility reported in the Asia Pacific study?
According to CLSI 2006 susceptibility breakpoints (17), 93% of all isolates were susceptible to levofloxacin, making it the most active agent tested. This ranged from a total levofloxacin susceptibility rate of 79% in Taiwan, 95% in Indonesia, 97% in Thailand, 93% in Hong Kong, and 100% in Malaysia, the Philippines, and Korea. The second most active agent was cefepime, which was active against 90% of the pathogens. The percentage susceptible to imipenem, ceftazidime, ceftriaxone and amoxicillin/clavulanate was 86%, 85%, 81% and 67%, respectively.
