READ: Microbiology: Control of Microbial Growth

(4 RC) - To prevent the spread of human disease, it is necessary to control the growth and abundance of microbes in or on various items frequently used by humans. Inanimate items, such as doorknobs, toys, or towels, which may harbor microbes and aid in disease transmission, are called fomites. Two factors heavily influence the level of cleanliness required for a particular fomite and, hence, the protocol chosen to achieve this level… (Microbiology Chapter 13, 2016)

(3 RC) - Biofilms were long considered random assemblages of cells and had little attention from researchers. Recently, progress in visualization and biochemical methods has revealed that biofilms are an organized ecosystem within which many cells, usually of different species of bacteria, fungi, and algae, interact through cell signaling and coordinated responses… (Microbiology Chapter 9, 2016)

(4 RC) - Eukaryotic microbes are an extraordinarily diverse group, including species with a wide range of life cycles, morphological specializations, and nutritional needs. Although more diseases are caused by viruses and bacteria than by microscopic eukaryotes, these eukaryotes are responsible for some diseases of great public health importance… (Microbiology Chapter 5, 2016)

READ: Interior Insulation Applications in HVAC Systems

(1 RC) - One of the critical aspects of HVAC systems is the insulation used inside metal ductwork, air handlers, mixing boxes, and other components of HVAC systems. Insulation materials need to be understood and handled properly to ensure optimum system performance and compliance with regulations. This paper covers the specific topic of internally insulated sheet metal ductwork and HVAC system components. Related topics, such as flex duct and duct-board, may be discussed in future papers… (NADCA, Nov 2016)

(1 RC) - Coccidioidomycosis (Valley fever) is an infection caused by the environmental fungus Coccidioides spp. Approximately 40% of infected persons develop symptoms including fatigue, cough, fever, shortness of breath, and headache, typically after a 1- to 3-week incubation period (1). The infection is often clinically indistinguishable from community-acquired pneumonia caused by other pathogens… (CDC, Sept 2019)

(1 RC) - People are constantly exposed to mold in both indoor and outdoor environments and pinpointing one source of exposure can be difficult to impossible. In fact, exposure may come from multiple sources. The general public and some health care providers who are less familiar with the subject have attributed a burden of disease to mold that is disproportionate with symptoms. This document will attempt to give the practicing clinician a synopsis of the state of the art thinking about indoor mold, damp spaces, and health effects… (CDPH, Dec 2009)
