Abstract

The first strain of endemic typhus fever virus was isolated from a pool of 135 chicken fleas combed from 2 Norway rats trapped on a farm. The other strain was obtained from a pool of 30 chicken fleas taken from one Norway rat caught in a city. The virus was also recovered from the brains of the rats.
