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.
