Experimental intramammary infection of cows with Yersinia enterocolitica O9: cellular and immunologic responses. Academic Article uri icon

abstract

  • Three clinically normal cows were inoculated with viable Yersinia enterocolitica O9 by the intramammary route. This provoked an increase in the somatic cell count in milk from the inoculated quarter, but no obvious clinical response. Yersinia enterocolitica was isolated only sporadically from these cattle after inoculation. All cows showed a marked serologic response to Y enterocolitica and Brucella abortus. The anti-Brucella response provoked by inoculation of Yersinia was sufficient to render milk and serum Brucella-seropositive, as measured by the standard milk ring test, the quantitative milk ring test, and the serum agglutination test.
