[Bacteriological findings in materials from patients with nonspecific odontogenic infections].

The results of bacteriological studies made between 1964 and 1971 by workers at the Varia Laboratory, Institute of Medical Microbiology on 767 patients treated at the Clinic of Gnathofacial Surgery, Department of Medicine, Friedrich Schiller University at Jena, are evaluated. The testees (x=275) were included in groups with specific diagnoses, and a breakdown was made according to the detection of aerobic pus-forming germs. Gram-positive cocci were detected in 92% of the cases and their pathogenetic representatives, 76,5% of the cases. Rodshaped germs (Enterobacteriaceae, Pseudomonas) were observed only in 37,9% of the cases. Staphylococcus aureus, which accounted for 62,5%, was the most frequently observed species. It was followed, in order of frequency of detection, by greening streptococci and Staphylococcus epidermidis. Monoinfection was far more frequently observed than multi-infection. Also, the problems associated with the differentiation of streptococci are pointed out since other investigators found streptococci to be the most frequent agents producing odontogenic infections.
