P. multocida is a commensalist in human upper respiratory tracts.   from 2010 to 2015 there was a large mortality event among antelope in West Kazakhstan and Kosnstay.   They dies of hemorrhagic speticimia of a bacteria later identified through 16s ribosomal RNA sequencing as P. multocida.   These bacteria are stable commensals and opportunistic pathogens.

This paper was published two months ago, and I thought it was quite timely, considering it gives examples of both commensals and opportunistic pathogens.

I wonder how widespread some of these microbes can be?   These antelope had been followed for 40 years, and there was very little genetic diversity.   How can a microbe infect so many different forms of life and be the same, down to the subspecies.

This is a very interesting article, I’m wonder if an infected antelope become a vector for human infection. And are immunocompromised humans a cause for concern for infection.
