About This Book
The work explains that human and bovine tuberculosis are caused by tubercle bacilli and that infection depends on a susceptible host, presence of the bacillus, and opportunity for entry. It surveys how virulence, inoculum size, age, nutrition, prior disease, and site of entry shape clinical outcomes, and reports experimental observations on phthisiogenesis. Practical guidance covers hygiene of cow stables, safe milk production for infant feeding, and the method and distribution of protective inoculations for cattle. An appendix responds to criticisms and clarifies methodological points.
