TLDR
A growing body of theoretical and experimental population studies indicates that the interactions within and between bacterial species can have a profound impact on the outcome of competition in nature.Abstract:
Most natural environments harbour a stunningly diverse collection of microbial species. In these communities, bacteria compete with their neighbours for space and resources. Laboratory experiments with pure and mixed cultures have revealed many active mechanisms by which bacteria can impair or kill other microorganisms. In addition, a growing body of theoretical and experimental population studies indicates that the interactions within and between bacterial species can have a profound impact on the outcome of competition in nature. The next challenge is to integrate the findings of these laboratory and theoretical studies and to evaluate the predictions that they generate in more natural settings.read more

Prevalence of Borrelia burgdorferi sensu stricto, Borrelia afzelii, Borrelia garinii, and Borrelia valaisiana in Ixodes ricinus ticks from the northwest of Norway.
TL;DR: The overall infection rate of Borrelia species in Ixodes ricinus ticks is somewhat lower than that reported in the most recent study of the infection rate in southern Norway in 2010, and this study indicates that the infection rates varies from one year to another.

Commensal inter-bacterial interactions shaping the microbiota
TL;DR: In this article, the roles and mechanisms of selected inter-bacterial interactions in the microbiota, and their potential impacts on the host and pathogenic infection are highlighted, and the authors discuss challenges in mechanistically decoding these complex interactions, and prospects of harnessing them as future targets for rational microbiota modification in a variety of diseases.

Auto-regulation of DNA degrading bacteriocins: molecular and ecological aspects.
TL;DR: This work identified a novel means of induction unique to strains that kill by DNA degradation: these colicinogenic strains mildly poison themselves inflicting DNA damage that induces their DNA repair system (the SOS system), and their own expression.

The effect of phylogenetically different bacteria on the fitness of Pseudomonas fluorescens in sand microcosms
TL;DR: Investigation of how Pseudomonas fluorescens Pf0-1 responds to the presence of monocultures or mixtures of two phylogenetically different bacteria provides evidence that the performance of bacteria in soil depends strongly on the identity of neighbouring bacteria and that inter-specific interactions are an important factor in determining microbial community structure.

Smear-Ripened Cheeses
TL;DR: The current knowledge on the smear cheese microbiota is reviewed including the factors affecting ripening of smear cheeses, their microbial diversity, the sources of these microorganisms, their genomic features and functions and the pathogens associated with smear cheese and their control.

The Growth of Bacterial Cultures
TL;DR: Bacterial growth is considered as a method for the study of bacterial physiology and biochemistry, with the interpretation of quantitative data referring to bacterial growth limited to populations considered genetically homogeneous.

TL;DR: It is shown that bacterial communities of deep water masses of the North Atlantic and diffuse flow hydrothermal vents are one to two orders of magnitude more complex than previously reported for any microbial environment.
