Summary of infections caused by Serratia species other than S. marcescens

OrganismSpecimen(s)Comments (references)
S. liquefaciens Blood, urine, central nervous system specimens, respiratory sites, woundsSecond most common Serratia species involved in human infections (160); also involved in outbreaks (115, 132, 171, 344) and infections with contaminated medical equipment and products (44, 117, 123, 171, 175, 193, 200, 252, 261, 326, 412); like S. marcescens, involved in infections at nearly all sites (6, 15, 50, 75, 90, 115, 123, 126, 131, 132, 171, 174, 203, 262, 266, 271, 276, 308, 326, 332, 336, 344, 361, 401, 404, 412)
S. ficaria SputumPatient with upper respiratory tract infection; patient may have been colonized after eating figs (149)
Leg ulcerPatient regularly ate figs; organism recovered with 3 other Gram-negative rods (307)
Respiratory sitesProbably a colonizer; no fig association; recovered from two different patients (51)
Respiratory secretionsProbably a colonizer (98)
Knee woundProbably a colonizer (98)
Gallbladder empyema purulenceFour patients infected; gastrointestinal tract was thought to be source for the patients (8, 98)
Blood culturePatient with sepsis; source was probably the gut (98)
EyePatient with endophthalmitis; patient routinely ate figs, but it is unknown if this was source (25)
Forearm bite site purulence and blood culturesPatient developed cutaneous abscess (97)
S. fonticola Wound and respiratory tractUnknown clinical significance, several isolates (131)
Leg abscess purulence, blood culturesAfter patient had car accident (39)
Right hand woundAfter patient had car accident (305)
StoolFrom an immunocompromised patient with diarrhea (154)
Scalp woundRecovered from a hunter after he was bitten by a grizzly bear; recovered with several other bacteria (225)
Synovial fluidPatient with right knee hemarthrosis after falling off bike into hawthorns (154)
S. grimesii Several sitesThird most common Serratia species recovered from human clinical specimens according to one study by Grimont and Grimont (160)
Blood culturesRecovered from three patients, but the clinical significance is not clear (131)
Several sites?Nine strains recovered from human specimens and one from a brain abscess, but the clinical significance is not discussed (368)
S. odorifera Several sites23 strains isolated from human specimens, but clinical significance is not known (165)
Primarily respiratory tract specimens22 biogroup 1 isolates, most of which were probably not pathogenic (131)
Blood cultures, probably other sites27 biogroup 2 isolates, most of which were felt to be pathogenic; 1 isolate recovered from a blood culture from a fatal case (131)
Blood cultures, urinePatient with cirrhosis and septic shock (71)
SputumAcquired nosocomial infection of patient with pulmonary vascular congestion and bilateral pleural effusion (265); biogroup 1
Wound culturesSurveillance cultures from 2 patients in a cardiothoracic surgery unit; both cultures were biogroup 2 (331)
Blood culturesOutbreak of sepsis in 8 infants, due to biogroup 1; probably acquired from contaminated parenteral nutrition fluid; all of the infants died (136)
Blood culturesPatient with catheter-related sepsis caused by biogroup 1 (152)
SputumPatient with bronchial infection due to biogroup 1 (64)
UrineFive patients with UTI (263)
Blood cultures, urineFatal sepsis caused by biogroup 1 in a patient with chronic renal failure and diabetes (89)
Sputum, blood culturesPatient with pneumonia and sepsis caused by biogroup 1 (235)
S. plymuthica Face woundPatient with burn wound, may have acquired organism from a radiator; not thought to be a pathogen (78)
Respiratory tractRecovered from 5 different patients; no isolates thought to be pathogenic (131)
Blood cultures, catheter tipPatient with sepsis (189)
Femur woundPatient with femur fracture who developed wound infection and osteomyelitis (424)
Blood culturesThree patients with sepsis (62)
Wound culturesTwo patients with surgical wounds (62)
Peritoneal fluidPatient with abdominal infection (62)
Blood culturesPatient with sepsis and community-acquired pneumonia (317)
Blood culturesPatient with rectorrhagia and septic shock (111)
Peritoneal fluidPatient with peritonitis undergoing peritoneal dialysis (286)
Right leg wound culturePatient with right leg necrotic cellulitis (298)
Left femur wound culturePatient with left femur fracture (277)
S. quinivorans Bronchial aspirates, a pleural effusion sample, blood culturesPatient with respiratory distress and pneumonia (40)
S. rubidaea Several sites4th most common Serratia species recovered from human specimens according to study by Grimont and Grimont (160)
Respiratory sites, blood cultures, bile, wound cultures18 strains sent to CDC; clinical significance is unclear (126)
Various sitesSeveral strains, but clinical significance not discussed (131, 161, 203)
Left eyePatient with endophthalmitis after penetrating trauma to left eye (207)
Blood culturesPatient with bacteremia (332)
Blood cultures, bilePatient with bile tract carcinoma (388)
UrineThree cases of UTI (263)
Blood culturesPatient with sepsis (343)
