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 was born in 1822 in Dole, France. His discovery that most infectious diseases are caused by germs, also known as the germ theory of disease, is one of the most important in medical history. His work became the foundation for the science of microbiology, and a cornerstone of modern medicine. As Pasteur was growing up, his teachers thought that Louis was not fit for advanced studies, and felt he should carry on the work of his father as a tanner of leather.
