[Frequency of detection and the species composition of anaerobic gram-negative nonsporulating bacteria in suppurative pathology in emergency surgery].

The improved technique of cultivation allowed to detect obligatorily anaerobic microorganisms in 58 out of 94 samples from patients with purulent inflammatory processes. The results of the studies showed that anaerobic microorganisms were most frequently isolated from the exudate of the abdominal cavity and the purulent discharge of wounds in peritonitis patients. Gram-negative nonsporulating bacilli made up 25.3% of all the isolated cultures. The identification of these microorganisms allowed to determine that in the exudate of the abdominal cavity, the discharge of surgical and posttraumatic wounds, and of the pleural cavity the representatives of the family Bacteroidaceae mainly occurred. Most frequently B. thetaiotaomicron and B. fragilis were isolated.
