“The human colon is one of the most dense microbial ecosystems on Earth,” saysLaurie Comstockat the University of Chicago in Illinois. There are lots of different species of bacteria, and different strains within species, fighting for the same resources. Read more Secrets of a lo...

(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 ...
Production of biogenic amines "in vitro" in relation to the growth phase by Enterobacteriaceae species isolated from traditional sausages - ScienceDirect Histidine, lysine, ornithine and tyrosine decarboxylase activities were tested in 79 strains of Enterobacteriaceae (41 of Hafnia alvei, 17 of Serratia...
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 ...
Furthermore, many strains of Wolbachia induce cytoplasmic incompatibility (CI) to promote their spread among insect populations. Natural Wolbachia infection is common in over 50% of all insect species [19]. Wolbachia has been identified in Culex pipiens, Aedes albopictus, and Anopheles gambiae in ...
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...
Strain- and species-specific distribution of the streptomycin gene cluster and kan-related sequences in Streptomyces griseus. The streptomycin (SM) gene cluster was investigated for its distribution in streptomycetes by Southern hybridization using nick-translated DNA probes, whic... K Hotta,J Ishikawa...
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. ...
