Book Description
Excerpt from Bacteria, Yeasts, and Molds in the Home Bacteria, yeasts, and molds comprise a series of plants commonly known as microorganisms, or more popularly as microbes. It has for some time been recognized that together they form a group of the utmost importance not only to the physician but also to the agriculturist. To-day it is beginning to be appreciated that their rela tion to the ordinary household, and hence to the house wife, is even more intimate than to the physician. We are learning that many of the tasks of the housekeeper, some of which may be more or less unpleasant, have their foundation in bacteriology, and we are beginning to recog nize that these microorganisms constitute the foundation of the demand for cleanliness so forcibly emphasized in modern times. In the household microorganisms have an important bearing in three directions: I. They are the cause of the decay and spoiling of foods and many other products.

Not illustrated. 1917 edition. Excerpt: ... SECTION III--BACTERIA CHAPTER VIII THE GENERAL NATURE OF BACTERIA Our study of bacteria must be more extended than that which we have given to either molds or yeasts. While molds and yeasts are of significance in the household, the action of bacteria is much more fundamental and universal. Bacteria are far smaller than yeasts or molds (Fig. 46). They are commonly unknown to the housewife even by name, and rarely does she understand that they have any relation to household economy, or concern her very closely. Few have ever seen them or been aware of their existence. Nevertheless they are so constantly at work upon all kinds of food products in the pantry, that the affairs of the household are in a state of more or less constant warfare against these invisible, unrecognized, and unknown foes. They are more serious enemies than molds or yeasts. Chiefly to their presence and activity is due the fact that the preservation:6f-foods, even for a few days, is frequently Fig. 46. Showing the comparative size of molds (a), yeast (i and c), and bacteria (d). difficult, while special devices are required to preserve food indefinitely. To the housewife bacteria are of little value and are foes, like the molds, rather than allies, like the yeasts. This does not mean that they have no utility. On the contrary, they are of the most fundamental importance in nature, and it is no exaggeration to say that the very continuation of life is dependent upon their activity. To the agriculturist they are absolutely essential. They are the dairyman's close allies, and they are indispensable friends of many industries. By their action are produced some of the articles for our tables (vinegar) and also the flavor of butter and cheese. However, these phenomena do not...

Book Description
Almost all homes, apartments, and commercial buildings will experience leaks, flooding, or other forms of excessive indoor dampness at some point. Not only is excessive dampness a health problem by itself, it also contributes to several other potentially problematic types of situations. Molds and other microbial agents favor damp indoor environments, and excess moisture may initiate the release of chemical emissions from damaged building materials and furnishings. This new book from the Institute of Medicine examines the health impact of exposures resulting from damp indoor environments and offers recommendations for public health interventions. Damp Indoor Spaces and Health covers a broad range of topics. The book not only examines the relationship between damp or moldy indoor environments and adverse health outcomes but also discusses how and where buildings get wet, how dampness influences microbial growth and chemical emissions, ways to prevent and remediate dampness, and elements of a public health response to the issues. A comprehensive literature review finds sufficient evidence of an association between damp indoor environments and some upper respiratory tract symptoms, coughing, wheezing, and asthma symptoms in sensitized persons. This important book will be of interest to a wide-ranging audience of science, health, engineering, and building professionals, government officials, and members of the public.
