First author, last author and publication year of included publications, sorted by last author is shown in the left column. Total number of sequences included in the database from each publication is shown in the right column. In some cases, publications may contain additional sequences that did not meet our inclusion criteria--for example, sequences from isolates or patients with no brain sequences--and were therefore omitted.
