"Intestinal and Nasal Microbiota of Patients with Idiopathic Parkinson's disease"

"We will recruit 100 Parkinson’s disease patients and 100 control subjects. ... We will collect bacterial samples from the nose and stool of these subjects. ... we will read out the genetic code of all bacteria contained in these samples and will be able to identify which species of bacteria are present in the samples. Using complex cluster computing we will compare the pattern of bacterial species between Parkinson’s disease patients and controls and look for specific abnormalities in Parkinson’s disease patients."

IMHO this is well worth doing. The title mentions "Microbiota" which is broader than just bacteria, as mentioned in the description. I hope this wider definition is taken, with fungi being looked at as well.
