Black-pigmented gram-negative anaerobes in endodontic infections.
Necrotic dental root canal infections are polymicrobial infections dominated by anaerobic bacteria. The number of different species in one canal is usually low, approx. 4-7 species. The species isolated most frequently belong to the genera Prevotella, Porphyromonas, Fusobacterium, Peptostreptococcus, Eubacterium and Streptococcus. The frequency of isolation of black-pigmented Gram-negative anae...
متن کاملRapid presumptive identification of black-pigmented gram-negative anaerobic bacteria by using 4-methylumbelliferone derivatives.
A rapid method for presumptive identification of black-pigmented gram-negative anaerobic rods was developed. Using filter paper spot tests for indole production, sialidase, alpha-glucosidase, beta-glucosidase, alpha-fucosidase, and trypsinlike enzyme activities, 100% of Porphyromonas gingivalis, Prevotella intermedia, and Bacteroides levii and 89% of Prevotella corporis isolates were correctly ...
متن کاملGram-Positive Anaerobes in Periodontal Pathogenesis:
Advances in molecular research and the oral microbiome [3] study have depicted the number of oral bacteria (cultivable and not) to a mind-boggling 700 species! The subgingival biofilm is the primary etiology of periodontal disease initiation and progression and for this reason periodontal microbiology has been the focus of research over centuries. It has gone through paradigm shifts of ideologi...
متن کاملThe API ZYM system in the identification of Gram-negative anaerobes.
The API ZYM reactions of type species of Gram-negative anaerobes representative of those encountered in human infections and of 56 clinical isolates of such organisms, identified by conventional techniques, were investigated. The API ZYM test clearly distinguished between the different genera and species examined and appears to provide a simple, reliable method for the identification of this gr...
متن کاملOral colonization of Gram-negative anaerobes as a risk factor for preterm delivery.
BACKGROUND Preterm birth significantly impacts on neonatal morbidity and mortality and is apparently increasing world-wide. Several studies have attempted to define a causative role for periodontal disease in adverse pregnancy outcomes but few have focused on the microbiology of periodontal disease in relation to these outcomes. RESULTS The evidence for a positive correlation is strong, suppo...
