In present study, methanol extracts of the Chlorophycean group of seaweeds have been tested for their antibacterial activity against oral bacteria causing dental caries. Different concentrations of the extracts of the four species of seaweedsChaetomorpha antennina, Cladophora fascicularis, Spongomorpha indica and Ulva fasciata collected from sea coast of Visakhapatnam have been tested for their...

Nitrate and nitrite are present in the human oral cavity. The main origin of these components is nitrate that is contained in leafy vegetables such as lettuce and spinach (Tamme et al., 2006). Ingested nitrate is absorbed into human body by the intestine, and part of the absorbed nitrate is secreted into the oral cavity as a component of saliva. In the oral cavity, nitrate is reduced to nitrite...

Gingivitis is an inflammatory destructive disease mainly caused by microbial plaques. Gram-positive and gram-negative bacilli or cocci have been isolated from dental plaque and gingivitis. This study was going to isolate and characterize the pathogenic bacteria from gingival of 100 patients with oral gingivitis. Enriched and specific media used for isolation of bacteria. Identification of isola...

Determining the bacterial composition of the canine oral microbiome is of interest for two primary reasons. First, while the human oral microbiome has been well studied using molecular techniques, the oral microbiomes of other mammals have not been studied in equal depth using culture independent methods. This study allows a comparison of the number of bacterial taxa, based on 16S rRNA-gene seq...

When undergoing chemotherapy, it is easy for patients to develop an intraoral disorder as an adverse event. If intraoral disorder worsens, we cannot but stop chemotherapy. In this situation, oral bacteria are often detected in the blood. The goal of perioperative oral function management (POMF) during chemotherapy is to allow chemotherapy to proceed smoothly while maintaining the intraoral envi...

Modern hygienic practices are applied to avoid exposure to pathogens that spread via fecal-oral transmission. Despite this, the gastrointestinal tract is quickly colonized by fecal microbes. The hands are an important vector for the transmission of microbes, but the frequency at which fecal and oral microbes exist on hands and the source of those microbes have not been extensively described. Us...

The cell wall compositions of 41 strains of oral filamentous bacteria belonging to the genera Fusobacterium, Leptotrichia and Bacterionema were examined by paper chromatography. Leptotrichia walls showed principally alanine, glutamic acid, DAP, glycine and aspartic acid. The genus Bacterionema had the same amino acids but aspartic acid appeared to be a minor component and was not detected in th...

BACKGROUND Oral sex among teenagers is on the rise. Similarity between the oral flora and organisms recovered from nongonococcal urethritis and prostatitis, points to retrograde entry of bacteria from oral cavity into the urethra following insertive oral intercourse. PRESENTATION OF THE HYPOTHESIS Chlorhexidine has a wide spectrum of anti-bactericidal activity encompassing gram positive and n...
