Comparison of risk factors and outcome in patients with Enterococcus faecalis vs Enterococcus faecium bacteremia.
Scandinavian Journal of Infectious Diseases. 30(2):153-7, 1998.The purpose of our study was to determine retrospectively the risk factors for the acquisition of Enterococcus faecalis vs E. faecium bacteremia, as well as the clinical outcomes of these patients.62 patients with Enterococcus faecalis bacteremia were compared to 31 patients with E. faecium bacteremia. Haematologic malignancies, neutropenia, high-risk source and previous use of aminoglycosides, carbapenems, cephalosporins and clindamycin were significantly associated with E. faecium bacteremia. Instead, urinary catheterization was found to be related to Enterococcus faecalis bacteremia. The mortality rates within 7 d and 30 d were 13% and 27%, respectively, in patients with E. faecalis bacteremia and 6% and 29%, respectively, in patients with E. faecium bacteremia.There was no difference in mortality between E. faecalis and E. faecium bacteremia, nor was there a difference in seriousness of disease at the time of bacteremia. In the subgroups of patients with monomicrobial or clinically significant E. faecalis vs E. faecium bacteremia, the mortality rates were similar to the results of all subjects.Our results do not support the theory that E. faecium would be a more virulent organism than E. faecalis | View Page |

How far should a clinical laboratory go in identifying anaerobic isolates, and who should pay?
Clinical Infectious Diseases. 16 Suppl 4:S435-8, 1993Identification of anaerobic bacteria in specimens from sites of infection due to mixed organisms can be time-consuming and expensive. Laboratories should limit anaerobic workups by testing only those specimens that have been properly collected and transported to the laboratory.Use of selective and differential media for initial processing can provide rapid and relevant information to the clinician. Anaerobes isolated from normally sterile sites and sites of serious infection should always be completely identified. Group-or genus-level identifications may suffice in other instances.The Bacteroides fragilis group of organisms should always be identified because of their virulence and resistance to many antimicrobial agents.Some of the other organisms that warrant identification include Clostridium septicum (associated with gastrointestinal malignancy); Clostridium ramosum, Clostridium innocuum, and Clostridium clostridioforme (which are resistant to antibiotics); Clostridium perfringens (a cause of myonecrosis and gas gangrene,potentially serious infection); anaerobic cocci (which may be resistant to metronidazole and clindamycin); and fusobacteria (which may be virulent and resistant to clindamycin and penicillin). | View Page |

| Spleen Specimen A 23-year old man had complained of right lower quadrant abdomonal pain for approximately one week. Initially the pain was sharp and localized to a small area just above the right iliac crest.The pain subsided for approximately two days, but then recurred more diffusely over the lower abdomen, accompanied by cramping and mild diarrhea.The onset of fever and vomiting promted a visit to the emergency room. His temperature was 101 F, pulse was 90/minute, and palpation of the right lower abdomen elicited severe pain.The white blood count was 23,000/mm with a distinct left shift, including 5% metamyelocytes.Emergency surgery was performed for a large peri-appendiceal abscess. During surgery, multiple abscesses were noted in the spleen, which was removed (see photograph).Recovery was uneventful following 5 days of adjuvant clindamycin therapy. | View Page |

Streptococcus milleri group: renewed interest in an elusive pathogen.
European Journal of Clinical Microbiology & Infectious Diseases.11:491-8, 1992The following review examines the bacteriological characteristics, epidemiology, pathogenicity and antimicrobial susceptibility of the "Streptococcus milleri group". "Streptococcus milleri group" is a term for a large group of streptococci which includes Streptococcus intermedius, Streptococcus constellatus and Streptococcus anginosus.Usually considered commensals, these organisms are often associated with various pyogenic infections including cardiac, intra-abdominal, subcutaneous and central nervous system infections, particularly with the formation of abscesses.Organisms of the "Streptococcus milleri group" are often unrecognized pathogens due to the lack of uniformity in classifications and difficulties in microbiological identification. Penicillin G, cephalosporins, clindamycin and vancomycin all possess activity against these streptococci.Use of agents with poor activity may promote infections with "Streptococcus milleri group" and allow it to exhibit its pathogenicity. An understanding of these organisms may aid in their recognition and proper treatment. | View Page |

Eikenella corrodens infections. Case report in two adolescent females with IDDM.
Diabetes Care. 19:1011-3, 1996OBJECTIVE: To alert physicians caring for patients with diabetes to the microorganism Eikenella corrodens and to discuss the appropriate preventive and therapeutic measures to take against this potentially morbid opportunistic Gram-negative bacilli.CASES: We present two cases of extra-oral E. corrodens infections in adolescent females with IDDM. The first patient had diabetes of 4 years' duration, which was moderately well controlled. Chronic finger biting resulted in a complex felon that evolved gradually and worsened while the patient received cephalexin orally. Delay in seeking further intervention resulted in necrosis of her distal fingertip and nail bed. The second patient had poorly controlled diabetes for 5 years. She developed an acute thigh abscess at an insulin injection site that resolved after drainage and intravenous antibiotics.CONCLUSIONS: E. corrodens commonly inhabits the human oral cavity and becomes a pathogen mostly when host defenses are impaired, causing abscesses and infections that are at times fatal. Patients with IDDM are compromised hosts and with daily microtrauma to their skin via glucose monitoring and insulin injections, are prone to develop E. corrodens infections that can be introduced through oral secretions by licking or biting their skin. Educational efforts aimed at preventing exposure of traumatized skin to oral secretions can minimize the risk of E. corrodens infections in compromised hosts.Early intravenous administration of antibiotics, bearing in mind E. corrodens resistance to clindamycin, metronidazole, and other antibiotics, coupled with prompt surgical intervention, is essential in successfully managing E. corrodens infections. | View Page |
