Cellular distribution of a feminizing microsporidian parasite: a strategy for transovarial transmission [PDF]

open access: yes, 1997
The cellular distribution of a vertically transmitted, feminizing microsporidian was followed in its host Gammarus duebeni. In adult females the parasite was restricted to gonadal tissue, in particular primary and secondary follicle cells.

Conservation of the “Outside-in” Germination Pathway in Paraclostridium bifermentans

open access: yesFrontiers in Microbiology, 2018
Clostridium difficile spore germination is initiated in response to certain bile acids and amino acids (e.g., glycine). Though the amino acid-recognizing germinant receptor is unknown, the bile acid germinant receptor is the germination-specific ...

Woodpeckers can act as dispersal vectors for fungi, plants, and microorganisms

open access: yesEcology and Evolution, 2021
Bird‐mediated dispersal is presumed to be important in the dissemination of many different types of organisms, but concrete evidence remains scarce. This is especially true for biota producing microscopic propagules.

Development of an Effective Nontoxigenic Clostridioides difficile–Based Oral Vaccine against C. difficile Infection

open access: yesMicrobiology Spectrum, 2022
The symptoms of Clostridioides difficile infection (CDI) are largely attributed to two C. difficile toxins, TcdA and TcdB. Significant efforts have been devoted to developing vaccines targeting both toxins through parenteral immunization routes. Recently,

Penicillin-binding proteins of protoplast and sporoplast membranes of Streptomyces griseus strains [PDF]

open access: yes, 1988
Membrane-bound penicillin-binding proteins (PBPs) of two Streptomyces griseus strains that sporulate well in liquid and solid medium have been investigated during the course of their life-cycle.

Characterization of the pathogenicity of a Bacillus cereus isolate from the Mariana Trench

open access: yesVirulence, 2022
Bacillus cereus is an important opportunistic pathogen widely distributed in the environment. In this study, we reported the isolation and characterization of a B. cereus isolate, MB1, from the Challenger Deep of the Mariana Trench.

Bacillus subtilis Spore Inner Membrane Proteome.

open access: yesJournal of Proteome Research, 2016
The endospore is the dormant form of Bacillus subtilis and many other Firmicutes. By sporulation, these spore formers can survive very harsh physical and chemical conditions. Yet, they need to go through germination to return to their growing form.

Lack of ecological context can create the illusion of social success in Dictyostelium discoideum [PDF]

open access: yesPLoS Comput Biol 12(12): e1005246. 2016, 2016
Studies of cooperation in microbes often focus on one fitness component, with little information about or attention to the ecological context, and this can lead to paradoxical results. The life cycle of the social amoeba Dictyostelium discoideum includes a multicellular stage in which not necessarily clonal amoebae aggregate upon starvation to form a ...

Establishment of surface functionalization methods for spore-based biosensors and implementation into sensor technologies for aseptic food processing [PDF]

open access: yes, 2020
Aseptic processing has become a popular technology to increase the shelf-life of packaged products and to provide non-contaminated goods to the consumers. In 2017, the global aseptic market was evaluated to be about 39.5 billion USD.
