Biological Profiles in Drinking Water
Published in Edwin E. Geldreich, Microbial Quality of Water Supply in Distribution Systems, 2020
Candida albicans is an opportunistic pathogen that becomes dangerous to individuals stressed from diabetes, cancer, and immunological defects associated with AIDS, or through use of immunosuppressants in organ transplants and the application of broad-spectrum antibiotics.254 Less severe but still very debilitating are yeast infections associated with diaper rash among infants and vaginitis in women from contaminated water contact or from sexually transmitted infections.255

The human skin is inhabited by abundant and diverse microbial communities, including bacteria, fungi, and viruses. These microorganisms colonize different parts of the human skin according to their specific growth requirements. For example, lipophilic microorganisms such as Propionibacterium, Malassezia, and mites mainly colonize sebaceous areas [1–3]. Staphylococcus, Corynebacterium, and foot fungi prefer glabrous, humid skin such as the toe web [1,4]. Many common skin diseases are closely related to microbial populations. Previous studies have shown that Malassezia has a direct causal relationship with symptomatic skin diseases such as folliculitis, dandruff, and seborrheic dermatitis [5]. Candida albicans are usually asymptomatic in the skin and oral areas of the human body. However, alterations in the host microbiota or variations in the colonization environment can lead to the overgrowth of C. albicans, which causes thrush and diaper rash [6]. Staphylococcus epidermidis is a common symbiotic bacterium of the skin [7], and it has been reported to be the most common pathogen in indwelling medical devices, causing infections of prosthetic joints and vascular grafts [8]. Therefore, it is very important to find an effective method for controlling the excessive colonization of skin microbes and maintain the balance between skin microbes and the host.

Zinc oxide is a safer highly efficient antimicrobial agent that has found use in food and agricultural systems [48]. In addition to its antibacterial activity, low thermal expansion coefficient, and better lubricity properties, ZnO has been utilized as an additive material to improve coating characteristics with less bacterial contamination on implantable materials such as screw and plate. Its antibacterial properties with their deodorizing ability make them applicable for various products as cotton fabrics, diaper rash preventing agents, antiseptic ointments, and anti-dandruff shampoos [49].
