Yersinia pestis

Scanning Electron Micrograph of a Flea. See PHIL 11436 for a colorized version of this image.Created:

This image depicts a Petri dish containing a sheep’s blood agar (SBA) medium, which had been inoculated with Gram-negative Yersinia pestis bacteria. Y. pestis is the pathogen responsible for causing human plague. This was the appearance of the colonial growth after 96 hours of incubation at 25º C.People usually get plague from being bitten by a rodent flea that is carrying the plague bacterium or by handling an infected animal. Millions of people in Europe died from plague in the Middle Ages, when human homes and places of work were inhabited by flea-infested rats. Today, modern antibiotics are effective against plague, but if an infected person is not treated promptly, the disease is likely to cause illness or death.Created: 2009

The enzyme is a dimer (two identical subunits around a vertical axis), and each of the two subunits forms a central barrel made of eight strands surrounded by short helices. The active site is believed to lie inside the barrel.
