Co-infection with Wolbachia and Cardinium may promote the synthesis of fat and free amino acids in a small spider, Hylyphantes graminicola

Associations between endosymbiotic bacteria and their hosts are widespread in nature and have been demonstrated extensively; however, only a few studies have examined how facultative symbionts affect host nutrition and metabolism. To gain insight into the associations between facultative symbionts and host nutrition and metabolic activity, we detected endosymbiotic infection in a small spider species, Hylyphantes graminicola, and established two...
