Denominators differ for each level: for blood cultures collected, the denominator is all patients; for pathogen isolated, the denominator is number of patients with blood cultures and for individual pathogens, the denominator is the total number of pathogens.
Only fully speciated pathogens of clear clinical significance for which >4 cases were observed are displayed. Pathogens not included in the table include: Acinetobacter, non-baumannii (14), Bacillus cereus (7), Brevundimonas (3), Enterobacter cloacae (n = 3), Enterobacter, other (2), Enterococcus faecium (n = 1), Enterococcus, other (2), Mycobacterium tuberculosis complex (later confirmed as Mycobacterium bovis BCG16, n = 1), Streptococcus agalactiae (n = 1), Citrobacter freundii (n = 1), Ralstonia (n = 1) and Proteus species (1). Several Streptococcus species that were likely contaminants were identified: Streptococcus anginosus (n = 4), Streptococcus mitis (n = 11) and Streptococcus salivarius (n = 4) (not included in count of pathogens isolated).
