Bacteria are organisms that consist of a single cell without a nucleus and with distinct structural, physiological and evolutionary characteristics. Bacteria form one of the three domains of life; the others are archaea and eukaryotes. Bacterial species and their habitats exhibit great diversity. ...
(1–10 millimeters in diameter) at first with a rather smooth surface but later with a weft of aerial mycelium that may appear granular, powdery, or velvety. The many species and strains ofStreptomycesproduce a wide variety of pigments that color the mycelium and the substrate; they also ...
megacephala,, and 13 unique to M. domestica,/i>. Half of these 18 species were pathogenic, two or three others were food spoilers and the rest were environmental or commensal bacteria from soil or plant matter. This study added three new pathogenic strains of bacteria and one new ...
2002). Within a bacterial species, a strain is defined as “the descendant of a single isolation in pure culture and usually made up of a succession of cultures ultimately derived from an initial single colony” (Staley and Krieg 1984). Although the strains of a given species share many ...
Phenotypic data confirmed the identities of isolates belonging to well-characterized species. Representatives of the phylum Actinobacteria were recovered in much lower numbers ( n = 11). Many of the bacilli exhibited antimicrobial activity against one or more strains of Clostridium difficile, Clostridium...
the surface of the host tissue becomes an ecosystem where the cells of different species andstrainsof bacteria interact and compete for resources. We knew that some of these bacterial strains have the capacity to attack and kill other strains, but we didn't know how this mechanism is regulated...
SUMMARY: Deoxyribonucleic acid reassociation was used to assess divergence in species of Citrobacter and Citrobacter-like strains. Typical strains of Citrobacter freundii were highly related. Antigenically atypical strains and most bioch... JH Crosa,AG Steigerwalt,GR Fanning,... - 《Journal of General...
Bacterial strains and growth protocol We have performed the experiments using two robust swarming bacteria, yielding essentially the same results. The first wasB. subtilisstrain 3610 (wild type), which is a Gram positive rod-shaped (0.8 × 5 μm) species, used as a model system in many ...
minutissimum, andDermabacter hominis. Altogether 14 species and related genera were found. We observed the best inter-assay agreement when identifyingC. seminale. Biofilm was observed in 7 out of 24 strains. The biofilm-producing strains belonged toArthrobacter cumminsii,Dermabacter hominis,C. ...
So where have these good germs been lurking all your life In your intestines, especially the lower section called the colon, which harbors at least 400 species of bacteria. Which ones you have depends largely on your environment and diet. An abundance of good bacteria in the colon generally ...
