Most frequent pathogens were Escherichia coli (n = 10), Enterococcus faecium n = 8, Enterobacter cloacae (n = 7), Klebsiella pneumoniae (n = 6), Pseudomonas aeruginosa (n = 3), Candida spp (n = 5).
Most frequent pathogens were Staphylococcus aureus and Escherichia coli.
The most frequent pathogens were methicillin-sensitive S. aureus (36 (26%)), P. aeruginosa (35 (25%)) and S. pneumoniae (16 (12%)).
During the 2006 2010 period, most frequent pathogens were gram-negative bacteria (P. aeruginosa, E. coli, K. pneumoniae) and fungi (C. parapsilosis, C. albicans), while coagulase-negative Staphylococci dropped down to 5.2%.
The median delay between ECMO initiation and bloodstream infection occurrence was 8 days (range 2 to 59 days) and the most frequent pathogens were Gram-negative bacilli including Enterobacteriaeceae, Candida sp. and Enterococcus sp. Neurologic complications of ECMO occurred in one patient in each ECMO type group.
The second most frequent pathogen is S. aureus [ 2, 3, 10, 11] Previously published microbiologic profile of CSF shunt infections is showed in Table 4.
The most frequent pathogen was S. aureus, in most cases originating from surgical-site infections, followed by E. coli as a cause of nosocomial urinary-tract infections and Enterococcus spp. from surgical-site infections.
The second most frequent pathogen was Salmonella spp., the causative agent in 34,664 cases (34%); distribution of serovars is shown in Table 2. Of all cases of gastroenteritis, Yersinia spp. accounted for 5,133 (5%) cases; Shigella spp. 3,813 (4%); and EHEC 820 (<1%).
The antimicrobial potency and spectrum for 17 selected antimicrobial agents of different classes against the five most frequent UTI pathogens are summarized in table 2. Among the β-lactum antibiotics, imipenem had the widest coverage against E. coli isolates (100%), followed by amikacin (49%), and extended spectrum cephalosporins (15 45%).
