Studying the Competence Regulon Quorum Sensing Circuity in Streptococcus mitis
… for resistance development. Streptococcus mitis , a pathogenic bacterium, utilizes the comABCDE competence regulon QS circuity. However, the competence stimulating peptide (CSP), the signaling molecule, that is responsible for QS activation, is not identified yet. In this work, we set out …

Structure–Activity Analysis of Peptide-Mediated Quorum Sensing in Streptococcus mitis
… study we examined QS modulation in Streptococcus mitis, a commensal oral bacterium that has recently been identified as an opportunistic pathogen capable of causing serious infections in immunocompromised individuals. The competence regulon QS system in S. mitis is controlled by the …

Modelagem matemática do crescimento somático e mortalidade do ouriço-do-mar Cassidulus mitis Krau, 1954 (Echinoidea: Cassidulidae)
The somatic growth of Cassidulus mitis Krau, 1954, a tropical brooding species, from a population located at the Vermelha Beach, Rio de Janeiro, Brazil, was analyzed by observing the monthly size distributions from December 1998 to April 2000, as well as by a mark-recapture experiment. These data …

Phylogenetic Analysis Suggests Horizontal Gene Transfer Event Within the Mitis Group Within the Genus Streptococcus Involving L-Amino Oxidase In Streptococcus Oligofermentans
<p>This phylogenetic study was undertaken in order to provide further elucidation to evolutionary relationships within the genus streptococcus. The inhibition by Streptococcus oligofermentans of Streptococcus mutans is of particular interest. A comprehensive mechanism for this inhibition has been …

The Physiological Response of sub-Arctic Lichens to Their Abiotic Environment
… (68.37˚N, 18.69˚E). Nephroma arcticum, Cladina mitis, C. stellaris and C. rangiferina, which are found in contrasting niche habitats within the same ecosystem, have been studied. An oxygen electrode apparatus has been used to study the effects of air temperature, thallus irradiance intensity and …

Diversity of Form, Content, and Function in the Vocal Signals of Adult Male Blue Monkeys (Cercopithecus mitis stuhlmanni): An Evolutionary Approach to Understanding a Signal Repertoire
… of adult male blue monkeys (Cercopithecus mitis stuhlmanni). Specifically, I examined three elements of vocal signals - acoustic structure, signal content, and adaptive function - across the entire male repertoire, and used results to infer mechanisms of selection on signal usage and …

Studies on pneumococci isolated from children in the Sheffield area.
… were seen in the shape and colour of colonies on Mitis salivarius agar, CO2 requirement, haemolysins and sensitivity to tetracycline. Another antibiotic, mecillinam, was found for the practical recognition of penicillin-tolerant strains as an alternative to the use of cloxacillin for this purpose. …
