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 کاملMRS Shimming: An Important Point Which Should not be Ignored
Introduction: Proton magnetic resonance spectroscopy (MRS) is a well-known device for analyzing the biological fluids metabolically. Obtaining accurate and reliable information via MRS needs a homogeneous magnetic field in order to provide well-defined peaks and uniform water suppression. There are lots of reasons which can disturb the magnetic field homogeneity which can be corrected by a proc...
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 کاملBacteroides endodontalis and other black-pigmented Bacteroides species in odontogenic abscesses.
Twenty-eight odontogenic abscesses were examined for the presence of black-pigmented Bacteroides spp. Of the 28 samples, 26 were found to contain one or more species of black-pigmented Bacteroides. Abscesses were divided into three categories according to the tissue of origin: endodontal, periodontal, and pericoronal. Four abscesses which developed after extraction were also examined. It was fo...
متن کاملGRAM NEGATIVE BACILLI IN BURNS
In a period of nine months, 225 strains of Gram-negative bacilli isolated from burns were identified by a variety of tests in two burn centers in Tehran. The most common species were Pseudomonas aeruginosa, Pseudomonas fluorescens, Escherichia coli, Enterobacter agglomerans, Enterobacter cloacae and Klebsiella pneumoniae. Many strains of acinetobacter spp, providencia spp, proteus spp, ser...
