Pathogen-microbiome interactions and the virulence of an entomopathogenic fungus.

Unlabelled: Bacteria shape interactions between hosts and fungal pathogens. In some cases, bacteria associated with fungi are essential for pathogen virulence. In other systems, host-associated microbiomes confer resistance against fungal pathogens.

Aphid facultative symbionts confer no protection against the fungal entomopathogen Batkoa apiculata.

Fungi in the family Entomophthoraceae are prevalent pathogens of aphids. Facultative symbiotic bacteria harbored by aphids, including Spiroplasma sp. and Regiella insecticola, have been shown to make their hosts more resistant to infection with the fungal pathogen Pandora neoaphidis.

Uncovering the hidden bacterial ghost communities of yeast and experimental evidences demonstrates yeast as thriving hub for bacteria.

Our major concern was to address "yeast endobacteria" which was based on a few reports in the recent past where bacteria may find yeast as a niche for survival. In this study, we report the microbiota of twenty-nine axenic yeast cultures recovered from different habitats based on their 16S rRNA gene-amplicon metagenomes. Yeasts were identified based on D1/D2 or ITS gene sequences.
