Dear authors, I was quite shocked that you did not reference our 2019 Nature paper, entitled “Intestinal infection triggers Parkinson’s disease-like symptoms in Pink -/- mice” where we developed the model of infecting mice with a PD-related mutation with Citrobacter rodentium four times at one month intervals to trigger motor symptoms.

Given the striking similarities between the approaches and results, I can only assume that not citing us was an oversight on your part.

For your information, our paper can be found here: https://www.nature.com/articles/s41586-019-1405-y

Sincerely, on behalf of the four corresponding authors of the 2019 paper.
