CA, community-acquired infection; HA, hospital-acquired infection. *Other isolates include Enterobacter spp., (9), Pantoea spp. (2), Serratia marcescens (1), Shigella flexneri (1), Citrobacter freundii (1), Proteus mirabilis (1). † Statistically significant difference in susceptibility among hospital-acquired and community-acquired isolates, p < 0.05 by two-sided Fisher's exact test.
