What is the single season highest batting average of any pitcher in MLB history?   Since 1973, the highest single season batting average by a pitcher was in 1993 when Orel Hershiser hit .356 (26 for 73) for the Dodgers.

Causes. Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis.
Another contention is that unlike viruses, bacteria that cause kennel cough are not species specific. So in case of dogs with kennel cough caused by bacteria like Bordetella bronchiseptica, there are chances of humans contracting respiratory problems from them. In fact, Bordetella bronchiseptica is closely related to the agent, which causes whooping cough in humans.
