E. coli, Escherichia coli; K. pneumoniae, Klebsiella pneumoniae; P. aeruginosa, Pseudomonas aeruginosa; P. mirabilis, Proteus mirabilis; Enterococcus spp., Enterococcus species. First column include all sources of infection (n = 948), and first raw include the five more frequent bacteria taking as denominator the total number of isolations (n = 1074). All other isolates up to the total number are not included in the table. Denominators in central boxes are the total number of each row (sources)
