Interaction with refuse piles is associated with co-occurrence of core gut microbiota in workers of the ant Aphaenogaster picea

Comparing the diversity of gut microbiota between and within social insect colonies can illustrate interactions bacterial community composition host behaviour. In many eusocial species, different workers exhibit task behaviours. Evidence compositional differences core in worker types could suggest a microbial association with division labour among workers. Here, we present Aphaenogaster picea ant The genus is abundant worldwide, yet associated this group unstudied. Bacterial communities from samples study consist 19 phyla, dominated by Proteobacteria, Cyanobacteria Firmicutes. Analysis 16S rRNA gene sequences reveals distinct similarity clustering that have more refuse piles. Though nurse foraging ants are similar overall structure, groups differ relative abundances dominant taxa. Gut piles amplicon sequence variants Entomoplasmataceae. Interaction faecal matter via seems to greatest impact on taxa distribution, effect appears be independent type. This first report surveying microbiome ants.

Bumble bee gut microbial community structure differs between species and commercial suppliers, but metabolic potential remains largely consistent

Applied and Environmental Microbiology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 6, 2025

ABSTRACT Bumble bees are key pollinators for natural and agricultural plant communities. Their health performance supported by a core gut microbiota composed of few bacterial taxa. However, the taxonomic composition community structure bumble bee microbiotas can vary with species, environment, origin (i.e., whether colonies come from wild or commercial rearing facility), it is unclear metabolic capabilities therefore as well. Here we used metagenomic sequencing to examine composition, structure, potential across two different Bombus impatiens suppliers, B. , three other species sampled sites within native range all four species. We found that varied between populations origins suppliers. Notably, Apibacter consistently present in some species—suggesting may be previously unrecognized phylotype bees—and lack phylotypes populations. despite variation high-level was largely consistent hosts, including related host performance, though activity remains investigated. IMPORTANCE Our study first compare genome-level whole suppliers In addition, profiled full time. Overall, our results provide new insight into function will help researchers evaluate how well studies conducted one population translate Research on increasing relevance continue discover ways social influence health, decline abundance.

Captive-rearing changes the gut microbiota of the bumblebee Bombus lantschouensis native to China

PeerJ, Journal Year: 2025, Volume and Issue: 13, P. e18964 - e18964

Published: Feb. 13, 2025

Bumblebees play crucial roles as pollinators in both natural agricultural and ecological systems. Their health overall fitness are significantly affected by the gut microbiota, which can maintain intestinal homeostasis hosts regulating their nutritional metabolism. However, information about diversity of microbiota related functional changes during artificial rearing native species is currently limited. This study investigated dynamic remodeling Chinese bumblebee Bombus lantschouensis under captive rearing, supported 16S rRNA amplicon sequencing bacterial DNA. The typical microbial community composition was detected wild B. , with genus Gilliamella Snodgrassella identified dominant strains. Conversely, captive-reared group showed increased decreased abundance certain microorganisms. populations Bifidobacterium Saccharibacter Lactobacillus including Firm-4 Firm-5, were dramatically after captive-rearing became bacteria, while strikingly reduced. Notably, this found that pathogenic bacteria appeared intestines wild-caught disappeared when host reared conditions. shows bumblebees facilitates physiological metabolism commercial insects.

Host specificity of gut microbiota associated with social bees: patterns and processes

Microbiology and Molecular Biology Reviews, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

SUMMARYGut microbes provide benefits to some animals, but their distribution and effects across diverse hosts are still poorly described. There is accumulating evidence for host specificity (i.e., a pattern where different tend associate with distinct lineages), the causes consequences of this unclear. Combining experimental tests in laboratory broad surveys wild promising approach gaining comprehensive mechanistic understanding prevalence, origin, importance. Social bees represent an ideal testbed endeavor because they phylogenetically functionally diverse, host-specific, stable, tractable gut microbiota. Furthermore, western honeybee (Apis mellifera) emerging model system studying microbiota-host interactions. In review, we summarize data on prevalence strength social bee microbiota (bumblebees, stingless bees, honeybees), as well potential proven ecological molecular mechanisms that maintain specificity. Overall, found relatively strong likely results from several processes, including filtering mediated by immune priority effects. However, more research needed multiple species confirm these findings. To help future research, hypotheses field propose comparative tests. Finally, conclude review highlighting need understand how can influence health.
