Yersinia pestis bacterium
False-colour transmission electron micrograph of Yersinia pestis (blue & yellow), the bacterium which causes bubonic plague (the Black Death). The bacterium is primarily a flea-carried pathogen of rats. Transfer to man occurs when a flea is obliged to leave its dead rodent host and feed on human blood. Infection is rapid, causing swellings in the lymph nodes (buboes) and leading to septicaemia & pulmonary infection. Extensive control measures, directed against the rats as well as their fleas, have essentially banished the plague from Europe, but there are still many regions of the world where the disease occurs.

EDITORS COMMENTS
This print showcases the Yersinia pestis bacterium, responsible for one of history's most devastating pandemics - the bubonic plague, also known as the Black Death. In this false-colour transmission electron micrograph, we observe the bacterium in striking shades of blue and yellow. Yersinia pestis primarily thrives within fleas that infest rats, serving as a flea-carried pathogen. However, when these fleas are forced to abandon their deceased rodent hosts and seek nourishment from human blood, transfer to humans occurs rapidly. The consequences are dire: infected individuals experience swollen lymph nodes called buboes and suffer from severe bloodstream infections (septicaemia) and pulmonary infections. While extensive control measures have successfully eradicated the plague from Europe by targeting both rats and their fleas, it remains prevalent in various regions worldwide. This image serves as a reminder of humanity's triumph over this deadly disease while emphasizing its continued existence elsewhere. With a magnification level of x16,500 at 6x4.5cm size, this transmission electron micrograph offers an intricate glimpse into the world of bacteria causing immense devastation throughout history. It highlights the significance of microbiology research in understanding infectious diseases like pneumonic plague and septicemic plague caused by Yersinia pestis.
