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.
Louis Pasteur and the germ theory of disease. The work of people like Jenner and Semmelweiss led doctors and scientists to think that perhaps infectious diseases were caused by an infectious agent or 'germ'.This was the germ theory of disease.It took a very long time for this idea to be accepted.uch of the work that led to a wide acceptance of the germ theory is down to Louis Pasteur, helped by the development of microscope techniques by people such as Robert Koch which made microorganisms visible and identifiable. Pasteur made a number of important steps forward.
