including gram-negative rods (eg,Pseudomonas, Proteus, Serratia, Enterobacter, Citrobacter), anaerobes, and others (eg,Helicobacter cinaedi, Fusariumspecies). Although fungi (eg,Cryptococcus) and herpes simplex virus may also cause cellulitis, these causes are rare. ...
S. pneumoniae (uncommon) Group B streptococci (GBS) and gram-negative rods (GNRs): neonates Hib (rare) Pseudomonas aeruginosa and anaerobic bacteria: immunocompromised children Pasteurella species: cat and dog bites Eikenella corrodens: human bites ...
Gram stains of leg tissue samples, however, showed gram negative rods as did blood cultures sent from the ER. Despite full supportive measures, the patient remained unstable with multiple episodes of circulatory arrest culminating in death 29 hours after hospital admission. Cultures of blood, leg ...
Blood cultures taken in the ED on hospital day 0 from a peripheral intravenous access site at the right antecubital space grew gram negative rods from the aerobic bottle later speciated by Vitek® 2 system as Myroides spp. on day 5 of hospital stay. Growth was confirmed by a second set...
Blood cultures drawn on admission were positive with curved Gram-negative rods at day 5. Routine sub-cultures initially failed to isolate the organism; however, small, tan colonies were observed on sheep blood agar incubated under microaerobic conditions.H. caniswas identified by 16S rRNA ...
are non-fermented gram-negative rods that are widespread in the environment and colonize in the human skin. They are known to be a nosocomial pathogen causing, pneumonia, meningitis and bacteremia. Recently, they have been found increasingly in catheter-related infections (CRI). Thirty-seven ...
Cultures of samples from interdigital spaces yielded Beta-hemolytic streptococci in 17 (85%) of 20 cases, in 9 (45%) of 20 cases, and gram-negative rods in 7 (35%) of 20 cases. Only Beta-hemolytic streptococci were recovered significantly more often from patients than ...
