*Values are no. (%) except as indicated. The total number of potential pathogens for each study period was set as 100%. Coagulase-negative staphylococci, microcooci, and bacilli were judged as skin flora contaminants. The ratio of Plasmodium spp.–positive patients in regard to bacterial species respective groups is indicated. NA, not applicable; NF, Plasmodium spp. not found.
†Blood film for Plasmodium spp. was done in most but not all cases. If the clinical situation, patient history, or blood count strongly indicated bacterial infection, blood culture was taken as first diagnostic approach.
‡S. enterica serovar Enteritidis and serovar Typhimurium.
§Including Streptococcus spp., Enterococcus spp., Acinetobacter spp.
