The frequency of infection following oral and maxillofacial injury and clinical isolates from the wound in the oral cavity

Abstract

Clinicostatistical observation was conducted in 489 cases of oral and maxillofacial injury during the past 3 years. Bacteriological studies were carried out in 18 cases of new injuries. The susceptibilities of isolates from the wound in the oral cavity to ABPC, CFTM, CCL, CDX and CEX were determined. The results were as follows: 1) Infection following oral and maxillofacial injury was found in 12 cases (2.5%) out of 489 cases. Postoperative infection was found in 9 cases (3.9%) out of 231 cases operated on. Streptococcus was isolated from the pus in high frequency and was found in 7 cases out of 9 cases. 2) 55 strains were isolated from the wound of 18 cases. S. sanguis (66.7%), Peptostreptococcus sp. (38.9%) and Neisseria sp. (33.3%) were isolated in high frequency in all of the cases. As a whole, ABPC and CFTM exhibited strong antibacterial activities, but some highly resistant gram negative bacilli were found. CCL, CDX and CEX showed lower activity compared with the other 2 antiviotics.
