Wesbrook succeeded Frost as the Assist. for the St. Board of Health. First to offer formal courses in bacteriology at UM. As state dept. of health director, he performed routine bacteriological work only if it could be utilized for research. In other words, all samples had to be properly labeled, and further samples had to be available. Work in 1890's primarily on animal diseases, such as Bacillus anthracis, and the aerobic sporeformers, rabies, and infectious anemia of horses. Wesbrook also studied the diphtheria group, suggesting a scheme of relation between the diverse morphological types of diphtheria bacilli, with an eye toward correlating the forms to pathogenicity. He claimed that the rapidly growing bacilli with clubbed ends and polar granules are supposed to be the virulent forms.
His work on chlorination led him to investigate variability, as some strains of typhoid bacilli were more resistant to chlorination, yet less virulent.
In 1900, McDaniel and Wesbrook published a valuable classification of the several morphological types of the diphtheria bacilli (Transactions of the Association of American Physicians 15:198-223)
