Isolation of Pasteurella multocida subspec. Multocida from chronic periapical lesion: First isolation in ex-Yugoslavia)

Abstract

This study presents five isolates of Pasteurella multocida subsp. multo-cida isolated from chronic periapical inflammatory lesion. We described the methods of sampling and cultivation as well as diagnostic criteria. Pasteurella multocida was diagnosed on the basis of characteristic cultural and tinctorial properties and the facts that all strains produced indole and induced ornithine decarboxilation, glucose, saccharose and manitole fermentation. Isolates produced neither urease, nor fermented lactose and maltose. Further classification to subspecies multocida was based on the fact that all investigated isolates fermented trechalose, xylose and sorbitol the traits which are diagnostically significant for the species. Patients deny any contact with farm animals or pets, which indicates a possible aerosol transport and animal-human as well as human-human infection. We consider that this organism should be paid more attention by dentist, oral surgeons and microbiologists.
