Insect Gut Microbiota: Accessories to the Bite

Gut Microbiota and Neuropsychiatric Disorders

Impact of the Gut Microbiota on Vaccine Responses

Non-responsiveness or poor responsiveness to vaccines are challenging issues in vaccine development, and efforts have been made to find out the potential reasons for these conditions. Intestinal microbiome plays a key role in regulating and development of immune system and the composition and diversity of microbiota in different individuals on the one hand, and the imbalance of intestinal micro...

Psychobiotics and Brain-Gut Microbiota Axis

Fermented foods containing probiotic bacteria have been used for many years to improve the health or treatment of some diseases. Nowadays, the Therapeutic properties of probiotics are becoming more and more obvious to everyone, insofar as in recent years, more attention has been paid to the potential relation between gut microbiota and mental health. Several studies have shown that intestinal m...

Insect pathogenic fungus interacts with the gut microbiota to accelerate mosquito mortality.

The insect gut microbiota plays crucial roles in modulating the interactions between the host and intestinal pathogens. Unlike viruses, bacteria, and parasites, which need to be ingested to cause disease, entomopathogenic fungi infect insects through the cuticle and proliferate in the hemolymph. However, interactions between the gut microbiota and entomopathogenic fungi are unknown. Here we sho...

Genetically Modifying the Insect Gut Microbiota to Control Chagas Disease Vectors through Systemic RNAi

Technologies based on RNA interference may be used for insect control. Sustainable strategies are needed to control vectors of Chagas disease such as Rhodnius prolixus. The insect microbiota can be modified to deliver molecules to the gut. Here, Escherichia coli HT115(DE3) expressing dsRNA for the Rhodnius heme-binding protein (RHBP) and for catalase (CAT) were fed to nymphs and adult triatomin...
