Microorganisms are bugs that live alongside humankind that can either kill millions of people mysteriously and silently or can be beneficial to nature and human beings. This work speaks of several researchers (or hunters) of these harmful bacteria. / Los microorganismos son bichos que conviven con la humanidad y que, por una parte, pueden matar en forma misteriosa y en silencio a millones de personas y, por otra, son benéficos para la naturaleza y el ser humano. Esta obra habla de varios investigadores o cazadores de microbios nocivos, causantes de terribles enfermedades como la rabia, la tuberculosis, la difteria, la sífilis y el paludismo, entre otras. Anton Van Leeuwenhoek, Lazzaro Spallanzani, Louis Pasteur, Robert Koch, Emile Roux, Emil Behring, Theobald Smith, Elías Metchnikoff, Ronald Ross, Giovanni Battista Grassi, Paul Ehrlich, Walter Reed y David Bruce son hombres a quienes les debemos estar agradecidos por sus descubrimientos científicos.
