Detection of Herpesviruses and Parvovirus B19 in Gastric and Intestinal Mucosa of Chronic Fatigue Syndrome Patients

Detection of Herpesviruses and Parvovirus B19 in Gastric and Intestinal Mucosa of Chronic Fatigue Syndrome Patients

They tested 48 CFIDS patients and 35 healthy controls.
For EBV, HHV6, HHV7 there were no big differences between patients and controls .
These virusses are probably not relevant for CFS.

Parvovirus B19 DNA was detected in 40% of the patients, and in less than 15% of the controls.
Parvovirus B19 may be involved in the pathogenesis of CFS, at least for a subset of patients.

Anxiogenic effect of subclinical bacterial infection in mice in the absence of overt immune activation

Gut pathogens can communicate with the CNS and influence emotional behaviors such as anxiety and depression, even at extremely low levels and in the absence of an immune response.
Mice were orally infected with Campylobacter jejuni and Citrobacter rodentium. The measured IL-6 and leukocytes showed no clear immune response to this infection, but the mice had altered levels of anxiety-like behavior. If you are depressed or have anxiety it could possibly help to alter your gut microbes and add pro/prebiotics to your diet.
