Microbes are present in every environmental niche and live in close association with humans and each other. Members of these communities include bacteria, archaea, viruses, fungi, and protists. In the environment, microbes perform various roles and are essential in agriculture and food production. In humans and animals, microbes provide protection against foreign invaders, educate and stimulate...

A more sensitive test agar was developed to detect oral microbes with relatively low dextranase activity and to identify dextranase-negative mutants. Several oral streptococci that had previously been scored as dextranase negative readily decolorized the new, blue dextran-containing medium. To assess whether dextranase plays a role in glucan synthesis by oral streptococci, various glucan synthe...

Abstract Background Oral health status is directly associated with microbes present within it. The abundance of at the OSCC site more than its control site, representing possible role in progression development. Dysbiosis oral microbiota could be a crucial etiological risk factor elevation OSCC. This study aimed to analyze and assess: a) positive regulator cancer their b) pathways involved micr...

Oral microbes that colonize in the mouths of humans contribute to disease susceptibility, but it is unclear if host genetic factors mediate colonization. We therefore tested the hypothesis that the levels at which oral microbes colonize in the mouth are heritable. Dental plaque biofilms were sampled from intact tooth surfaces of 118 caries-free twins. An additional 86 caries-active twins were s...

In Indonesia, Caesalpinia pulcherrima (L) Swartz is widely grown as an ornamental, whereas it is used as a medicinal herb in Mexico as an alternative treatment for dental and oral infections. At present, only fruit and root parts of the plant are used. The aim of this study was is evaluate the anti-microbial activity of ethanol extract of fruit, leaves, flowers and stems against microbes that c...
