Beat policing is based on traditional policing (late 19th century) and utilises the close relationship with the community members within the assigned beat to strengthen police effectiveness and encourage cooperative efforts to make a safer community.
Yersinia pestis bacteria can cause three different types of plague: bubonic, septicemic, or pneumonic. In bubonic plague, the most common form, bacteria infect the lymph system and causes it to become inflamed.(The lymph or lymphatic system is a major component of your body's immune system. The organs within the lymphatic system are the tonsils, adenoids, spleen, and thymus.).n bubonic plague, the most common form, bacteria infect the lymph system and causes it to become inflamed.

The Yersinia pestis bacterium causes both bubonic plague, a form of the disease you get from a flea or rat bite, and pneumonic plague, a respiratory infection you get by inhaling the bacteria. Bubonic plague kills via a deadly blood infection, while pneumonic plague causes a fatal pneumonia. Now, scientists have uncovered the steps that led the ancestor of Y. pestis to evolve into the deadly pathogen that causes pneumonic and bubonic plague.
