Food sources: Vitamin B12 is found naturally in animal products (such as fish, poultry, meat, eggs, or dairy); it is also found in fortified breakfast cereals and enriched soy or rice milk. Most people have plenty of vitamin B12 in their diets. The main concern is whether vitamin B12 is adequately absorbed.
From Conservapedia. The Germ theory of disease, developed in the 1860s and 1870s by Louis Pasteur, states that tiny living beings are the cause of infectious diseases. The theory was developed to explain puerperal fever, or Child bed fever.nly after the germ theory was championed by Pasteur (see pasteurization) and Lister (namesake of Listerine mouthwash) did antiseptic medicine become popular. Prior to germ theory, it was widely believed that disease was spread by noxious odors.
After 1879, Louis Pasteur and Robert Koch were able to associate specific bacteria with certain diseases. Pasteur first developed his ideas of the germ theory from his work on Pebrine and chicken cholera in the 1870s. Then, in the 1880s, Pasteur solved anthrax and rabies disease plagues by treating sheep and dogs using the germ theory concept. Pasteur applied his germ theory to vaccinating people against deadly diseases.
