Understanding connections and roles of gut microbiome in cardiovascular diseases
Canadian Journal of Microbiology, Ahead of Print. The gut microbiome encompasses trillions of residing microbes, mainly bacteria, which play a crucial role in maintaining the physiological and metabolic health of the host. The gut microbiome has been associated with several diseases, including cardiovascular disease (CVD). A growing body of evidence suggests that an altered gut environment and gut-microbiome-derived metabolites are associated with CVD events. The gut microbiome communicates with host physiology through different mechanisms, including trimethylamine N-oxide generation, primary and secondary bile acid metabo...

Evaluation of biochars as carriers for Rhizobium leguminosarum
Canadian Journal of Microbiology, Ahead of Print. Peat is the standard carrier material used for commercial microbial inoculants produced in Canada and the United States. Peat is a slowly renewable resource and its production is extremely vulnerable to variable weather conditions. Furthermore, it may not be widely available in all countries. We investigated the potential to develop biochar as a carrier material. Our goal was to evaluate if different biochars perform comparably in supporting rhizobial survival, and what characteristics contribute to their ability to support rhizobial survival. Evaluation included characteri...

Fungal endophyte diversity in table grapes
In this study, we determined the fungal microbial endophyte diversity in North American table grapes found at a Winnipeg, Manitoba, market. The amplicon internal transcribed spacer (ITS) metagenomics approach was used to profile the fungal communities of the fruit endophyte microbiome of three table grape types. The data supported endophyte diversity in different table grapes, including possible bioactive, saprophytic, and pathogenic fungi. Culturable endophytes were isolated and identified by morphology and ITS amplicon sequencing. The majority of the isolated culturable strains included Alternaria spp. and Cladosporium s...

Lactobacillus rhamnosus cell-free extract targets virulence and antifungal drug resistance in Candida albicans
Canadian Journal of Microbiology, Ahead of Print. Candidiasis caused by multidrug-resistant Candida species continues to be difficult to eradicate. The use of live probiotic bacteria has gained a lot of interest in the treatment of candidiasis; however, whole-cell probiotic use can often be associated with a high risk of sepsis. Strategies manipulating cell-free methods using probiotic strains could lead to the development of novel antifungal solutions. Therefore, we evaluated the effect of three probiotic cell-free extracts (CFEs) on the growth, virulence traits, and drug efflux pumps in C. albicans. On the basis of its m...

CcpN: a moonlighting protein regulating catabolite repression of gluconeogenic genes in Bacillus subtilis also affects cell length and interacts with DivIVA
We report the interaction of CcpN with DivIVA of B. subtilis as determined using bacterial two-hybrid and glutathione S-transferase pull-down assays. Insertional inactivation of CcpN leads to cell elongation and formation of straight chains of cells. These findings suggest that CcpN is a moonlighting protein involved in both gluconeogenesis and cell elongation. (Source: Canadian Journal of Microbiology)

Various dictyostelids from the environment can produce multilamellar bodies
Canadian Journal of Microbiology, Ahead of Print. Multilamellar bodies (MLBs), structures composed of concentric membrane layers, are known to be produced by different protozoa, including species of ciliates, free-living amoebae, and Dictyostelium discoideum social amoebae. Initially believed to be metabolic waste, potential roles like cell communication and food storage have been suggested for D. discoideum MLBs, which could be useful for the multicellular development of social amoebae and as a food source. However, among dictyostelids, this phenomenon has only been observed with D. discoideum, and mainly with laboratory ...

Canadian Journal of Microbiology, Ahead of Print. To develop a library-dependent method of tracking fecal sources of contamination of beaches on the Atlantic coast of southwestern France, a library of 6368 Escherichia coli isolates was constructed from samples of feces, from 40 known human or animal sources collected in the vicinity of Arcachon Bay in 2010, and in French Basque Country, Landes, and B éarn, between 2017 and 2018.

Aluminum induces oxidative damage in Saccharomyces cerevisiae
Canadian Journal of Microbiology, Ahead of Print. The mechanism of aluminum toxicity was studied in the model cells of Saccharomyces cerevisiae. Cell growth of yeast was inhibited by aluminum. The spot assay showed that the mechanism of aluminum detoxification in yeast cells was different from that of heavy metal cadmium. After treatment with aluminum, intracellular levels of reactive oxygen species, protein carbonyl, and thiobarbituric acid reactive substances were dramatically increased. Meanwhile, the percentage of aluminum-treated cells permeable to propidium iodide was augmented significantly. These data demonstrated ...

Exposure of Agrobacterium tumefaciens to agroinfiltration medium demonstrates cellular remodelling and may promote enhanced adaptability for molecular pharming
Canadian Journal of Microbiology, Ahead of Print. Agroinfiltration is used to treat plants with modified strains of Agrobacterium tumefaciens for the purpose of transient in planta expression of genes transferred from the bacterium. These genes encode valuable recombinant proteins for therapeutic or industrial applications. Treatment of large quantities of plants for industrial-scale protein production exposes bacteria (harboring genes of interest) to agroinfiltration medium that is devoid of nutrients and carbon sources for prolonged periods of time (possibly upwards of 24 h).

Functional potential differences between Firmicutes and Proteobacteria in response to manure amendment in a reclaimed soil
Canadian Journal of Microbiology, Ahead of Print. Manure amendment generally bolsters soil organisms but not all bacteria equally. To understand why different taxa respond differently, we used shotgun metagenomic approaches to profile functional potentials and correlate them with taxon abundances. A soil originally unproductive was reclaimed using commercial manure and finally became productive. The abundance of Firmicutes in the soil decreased, whereas that of Bacteroidetes and Proteobacteria increased after manure addition. Thirty-nine KEGG modules were significantly different across fertilizer treatments. These modules ...
