Bacterial vaginosis (BV) has been considered to be the most prevalent infection found in sexually active women. BV is thought to play an important role in the premature rupture of membranes (PROM) and preterm birth. Preterm delivery accounts for a substantial percentage of low birth weight infants and perinatal mortality and morbidity. Bacteroides and Prevotella species have been isolated from ...

Sir, Prevotella spp. are Gram-negative, non-spore-forming anaerobes that are important members of the normal oral, colonic and vaginal flora in humans. These organisms have been isolated from patients with chronic sinusitis, brain abscesses and oral cavity infections often mixed with other anaerobes and streptococci. Metronidazole resistance among Prevotella spp. is rare. We report a clinical i...

the bacterial population found in the gingival sulcus region in periodontitis consists of gram negative microorganisms; most of them are obligate anaerobes and capnophil, including porphyromonas, prevotella, fusobaclenuin, welinella, actinobacillus actinomycetem comitans, eiknella and capnocytohaga. this study has been carried out to investigate anaerobic and capnophilic bacteria from 206 speci...

Bacteroides fragilis group and Bacteroides melaninogenicus group fluorescent-antibody kits were evaluated with 188 clinical specimens and 116 fresh aerobic and anaerobic bacterial isolates. Fluorescent-antibody and culture results corresponded in 88% of clinical specimens of the B. fragilis group and 94% of clinical specimens of the B. melaninogenicus group. There was greater than or equal to 9...

background. the most common species isolated from primary endodontic infections are black-pigmented bacteria. these species are implicated in apical abscess formation due to their proteolytic activity and are fastidious in nature. therefore, the present study was carried out to evaluate the presence and identification of various pigmented porphyromonas and prevotella species in the infected roo...

Previous analysis of the microbiology of advanced caries by culture and real-time PCR emphasized the high incidence and abundance of gram-negative anaerobic species, particularly Prevotella-like bacteria. The diversity of Prevotella-like bacteria was further explored by analyzing pooled bacterial DNA from lesions of carious dentine. This was achieved by amplification of a region of the 16S ribo...

Significant associations have been reported between (a) specific bacterial species isolated from root canals and (b) between individual bacterial species and endodontic symptoms and signs. The prime objective of this study was to determine whether particular combinations of specific bacteria are associated with individual endodontic symptoms and signs. Seventy root canals were investigated micr...
