Variation in Honey Bee Gut Microbial Diversity Affected by Ontogenetic Stage, Age and Geographic Location
TLDR
It is found that bacterial counts do not show only yearly cycles within a colony, but vary on the individual level, and redundancy analysis conducted using denaturing gradient gel electrophoresis identified bacterial species that were characteristic of each developmental stage.
Effects of chlorogenic acid, epicatechin gallate, and quercetin on mucin expression and secretion in the Caco‐2/HT29‐MTX cell model
TLDR
The polyphenols considered in this study may influence mucin secretion and act on diverse salivary substrates to change the barrier properties of mucins for mucus secretion in different ways.
Vagococcus entomophilus sp. nov., from the digestive tract of a wasp (Vespula vulgaris).
TLDR
Three unknown Gram-stain-positive, catalase-negative, facultatively anaerobic and coccus-shaped strains of bacteria were isolated from the digestive tracts of wasps and confirmed that the investigated strains were representatives of a novel bacterial species within the genus Vagoccocus.
Lactobacillus bombi sp. nov., from the digestive tract of laboratory-reared bumblebee queens (Bombus terrestris).
TLDR
Genotypes and phylogenetic analyses based on the phylogenetic markers hsp60, pheS, rpoA and tuf as well as phenotypic characteristics and the results of chemotaxonomic analyses confirmed that the new isolates belong to a novel species of the genus Lactobacillus, for which the name LactOBacillus bombi sp.
Evaluation of the infB and rpsB gene fragments as genetic markers intended for identification and phylogenetic analysis of particular representatives of the order Lactobacillales
TLDR
In conclusion, infB, rpsB regions and their concatenate were phylogenetically consistent with two widely applied alternative genetic markers in taxonomy of particular Lactobacillales genera encoding the 60 kDa chaperonin protein and phenylalanyl-tRNA synthetase, alpha subunit.
Plant alkaloid sanguinarine and novel potential probiotic strains Lactobacillus apis, Lactobacillus melliventris and Gilliamella apicola promote resistance of honey bees to nematobacterial infection
TLDR
Addition of low doses of both sanguinarine and non-pathogenic strains of selected bacteria had a positive impact on the resistance of honey bee to pathogen, and can serve as a valuable tool for immunological tests in honey bees.
In-hive variation of the gut microbial composition of honey bee larvae and pupae from the same oviposition time
TLDR
Although sample processing and extraction protocols may have had a significant influence, sampling is very important for studying the bee microbiome, and the importance of the number of individuals pooled in samples used for microbiome studies should not be underestimated.
Glutamine synthetase type I (glnAI) represents a rewarding molecular marker in the classification of bifidobacteria and related genera
The family Bifidobacteriaceae constitutes an important phylogenetic group that particularly includes bifidobacterial taxa demonstrating proven or debated positive effects on host health. The
Genetic marker-based multi-locus sequence analysis for classification, genotyping, and phylogenetics of the family Bifidobacteriaceae as an alternative approach to phylogenomics
TLDR
Several gene sequence and phylogenetic analyses revealed that concatenated gene regions allow for classification of Bifidobacteriaceae strains into particular phylogenetic clusters and groups.
Repellence and attraction of Apis mellifera foragers by nectar alkaloids
TLDR
It is confirmed that bees exhibit a preference for caffeine, and hypothesize that this is not due only to addictive behaviour but is at least partially mediated by taste preference, and observed no significant preference for nicotine or any other alkaloid.
