folliculitis: inflammation of the hair follicles. A particular type of skin irritation often caused by cutting oils (“oil boils”). Usually occurs on the forearms and thighs where oil-soaked clothing comes in contact with the skin. The cutting oil and grime from the work combine to plug the pores, resulting in inflammation, open sores, and often an acne condition

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.
A comprehensive summary of disease variants implicated in metal allergy
Published in Journal of Toxicology and Environmental Health, Part B, 2022
In addition to the many variants of ASIA that were correlated with metal hypersensitivity, allergic reactivity to sensitizing metals was also suggested to play a role in the promotion of a certain type of cancer – cutaneous T-cell lymphoma (CTCL). Many subtypes of CTCL were identified, but all variants of the disease are classified as extranodal non-Hodgkin’s lymphomas, wherein malignant monoclonal T-lymphocytes selectively infiltrate the skin (Bagherani and Smoller 2016). In the early stages of disease development, CTCL is often misdiagnosed as one of many common inflammatory skin conditions including ACD, psoriasis, lichen planus, folliculitis, or vitiligo (Hristov, Tejasvi, and R 2021). Interestingly, many subjects that develop CTCL have a history of these and other similar skin disorders. It is believed that these conditions often represent a precursor to cancerous transformation due to recurrent antigenic stimulation associated with chronic disease states. Accordingly, several cases of CTCL were correlated with chronic ACD induced by Cr, Ni, and Co (Khamaysi et al. 2011; Tilakaratne and Sidhu 2015).

Staphylococcus aureus (S. aureus) is one of the major causes for nosocomial and community-acquired infections that are associated with a number of diseases including endocarditis, osteomyelitis, pneumonia, toxic-shock syndrome, food poisoning, and various skin infections such as folliculitis, furuncles, carbuncles, abscess, and mastitis.[1–5] The treatment of these infections becomes increasingly challenging as there is a significant increase in the emergence of multi-drug resistance among S. aureus. Therefore, it is important to develop a novel anti-staphylococcal agent in order to eradicate antibiotic-resistant S. aureus infections.[6,7] One of the most promising methods to treat staphylococcal infections is the use of lysostaphin thanks to its specificity to staphylococci.[7–10]
