Question

"Day We Discovered Cause of 'White Death'"
by Dr. Howard Markel

Like many young physicians of this era, Koch was struck by an intense fascination with all things microscopic, a fixation some medical critics derided as “bacteriomania.” Unlike his senior colleagues who ascribed epidemics to the contamination of the air with foul or unpleasant emanations, a notion referred to as the miasmatic theory, Dr. Koch sided with those who would become the scientific revolutionaries of their day by asserting and ultimately proving that specific microbes were the cause of specific infectious diseases.
