What bacterium is responsible for the Plague?

The bacterium responsible for the Plague is Yersinia pestis. This pathogen is notorious for causing significant outbreaks throughout history, notably the Black Death in the 14th century. Yersinia pestis is primarily transmitted through the bites of infected fleas, which often inhabit rodent populations, linking wildlife to the potential spread of the disease to humans. Understanding this bacterium is essential for recognizing how zoonotic diseases can impact wildlife management and public health. This knowledge is particularly relevant to individuals involved in trapping practices, as they may encounter wildlife that could be carriers of the plague.

In contrast, the other bacteria listed are associated with different diseases: Staphylococcus aureus is commonly linked to skin infections and food poisoning; Escherichia coli is primarily known for gastrointestinal problems, especially strains leading to severe foodborne illness; and Streptococcus pneumoniae is primarily responsible for pneumonia and other respiratory infections. Each of these pathogens has distinct epidemiological characteristics and does not relate to the Plague or its transmission. Understanding the specific characteristics of Yersinia pestis aids in recognizing the health risks associated with wildlife and the importance of appropriate precautions during trapping activities.
