Legionella pneumophila

Legionella pneumophila is a type of bacteria that inhabits natural environments as soil, rivers and water bodies, and infection typically occurs through inhalation of water vapor or aerosols.

It proliferates in poor sanitary conditions of water circulation systems such as humidifiers, hot tubs (sauna).

Bacillus subtilis

Bacillus subtilis is generalist in nature, including dead grass and soil.

It is recognized as a safe bacterium with no reported pathogenic effects on humans.

Salmonella enteritidis

Salmonella is a bacterium that is widely found in nature, including humans, in the intestines of livestock, and in rivers. It is well known as a cause of food poisoning, causing symptoms such as diarrhea and nausea.

Klebsiella pneumoniae

Klebsiella pneumoniae is a Gram-negative bacterium typically a part of the human enterobacteria. It is a major pathogen of respiratory and urinary tract infections, and can also cause bacteremia and sepsis.

opportunistic infection

An infection that occurs more frequently or severe in patients with weakened immune systems, such as patients receiving chemotherapy and patients with blood disorders than in people with healthy immune systems.

Staphylococcus aureus

Staphylococcus aureus is a bacterium that lives on the skin and mucous membranes in many people. It can also cause skin infections and food poisoning.In case of a compromised immune system.

Pseudomonas aeruginosa

Pseudomonas aeruginosa is a type of commensal bacterium that is widely found in natural and living environments, from plant surfaces to the intestinal tracts of healthy people.
This bacterium is notorious for its resistance and can lead to serious infections, particularly in immunocompromised individuals and critically ill patients.

Candida albicans

Candida albicans is a fungus commonly found in the gastrointestinal mucosa of healthy individuals as a commensal organism and female reproductive system. It causes systemic infection as a causative agent of opportunistic infections in individuals with reduced resistance, such as cancer, leukemia, AIDS, and transplant patients.

Skin Barrier Functions

The functions of the skin to prevent external stimuli and foreign substances, such as allergy-causing substances, bacteria, and viruses, from entering the skin and to prevent evaporation of water from the body are referred to as the skin barrier function.
The skin of atopic dermatitis is naturally prone to dryness, and because the skin barrier function is impaired, it is unable to prevent foreign substances from entering the skin, causing inflammation, itching, eczema, and other symptoms.


A compound composed of iron and porphyrin. It combines with the protein globin to form hemoglobin. Hemoglobin transports oxygen to the body when iron molecules in heme combine with oxygen molecules.
