A novel <i>Erwiniaceae</i> gut symbiont modulates gene expression of the intracellular bacterium <i>Cardinium</i> in the stored product mite <i>Tyrophagus putrescentiae</i>.

ABSTRACT: We examined host and bacterial gene expression profiles in the stored product mite Tyrophagus putrescentiae co-infected with Wolbachia (wTPut) and Cardinium (cTPut) while varying the presence of the Erwiniaceae symbiont (SLS). SLS, a novel symbiont in the family Erwiniaceae, with a genome size of 1.7 Mb, is found in 16% of mite species in infected cultures. In addition, SLS was detected in mite feces but not in their eggs. Although Wolbachia expression remained unchanged, the presence or absence of SLS significantly affected Cardinium expression. It indicated that the effect of Wolbachia on SLS was neutral. In SLS-positive samples, Cardinium exhibited 29 upregulated and 48 downregulated genes compared to SLS-negative samples. F
