  1. aIsolates from blood in patients with pneumonia were K. pneumoniae (22.4%, 22/98), E. coli (16.3%, 16/98), S. maltophilia (11.2%, 11/98), Burkholderia pseudomallei (8.2%, 8/98), S. aureus (7.1%, 7/98) and S. suis (7.1%, 7/98) and other pathogens (23.5%, 27/98)
  2. bIsolates from blood in patients with meningitis were S. suis (40/72, 55.6%), K. pneumoniae (8/72, 11.1%), Stenotrophomonas maltophilia (7/72, 9.7%), S. aureus (5/72, 6.9%). Enterococcus species (2/72, 2.8%), Listeria species (2/72, 2.8%), E. coli (2/72, 2,8%), Salmonella enterica (2/72,2.8%) and each of S. pneumoniae, beta hemolytic Streptococcus, viridans group Streptococcus and Enterobacter species (1/72, 1.4%)
  3. cThere were 16 cases with liver abscess with isolates from blood were K. pneumoniae (8/16 or 50%), E. coli and Salmonella enterica (2/16 of each, or 12.5%), Aeromonas species, Enterobacter species, S. suis and viridans group streptococci (1/16 of each, 6.3%)
