ABSTRACT
The E-test is convenient for testing susceptibility of anaerobes. From September 1998 to September 1999, 194 strains (105 Gram-positive bacteria, 89 Gram-negative bacteria) of clinically relevant samples were tested against five antibiotics benzylpenicillin, amoxicillin-clavulanic acid, clindamycin, metronidazole and imipenem on blood agar plates. Resistance to benzyl penicillin is widespread and Gram-negative bacteria and resistance to amoxicillin-clavulanic acid is exceptional. Metronidazole is very effective against anaerobes except non-spore-forming aerotolerant Gram-positive rods and Peptostreptococcus micros.
ABSTRACT
Bacterial meningitis after pelvic trauma has never been described. We recently treated a patient who developed, during the course of his hospitalization, multiresistant enterococcal meningitis after severe pelvic injury, including a comminutive sacral fracture. Dural tear may have been the main factor leading to secondary infection of the cerebrospinal fluid. Treatment with intravenous continuous infusion of vancomycin plus rifampin, associated with closed subarachnoid drainage, resulted in a complete cure. Therapeutic cerebrospinal fluid levels of vancomycin were obtained only during the first 8 days of treatment. Use of glycopeptides in meningitis and the role of cerebrospinal fluid drainage are discussed. Physicians should be aware of the diagnosis and therapeutic features of this life-threatening complication.
