Infections of the Skin
Often, infections of the skin are painful and unpleasant. If the skin infections persist for a long period, they have adverse psychological effect on the person. People with weak immune system are more prone to the infections. Fungi, microscopic organisms and macro parasites cause infections. Bacterial and fungal infections are the most common skin infections. In this article, you will learn more about yeast, bacterial and fungal infections of the skin.
Bacterial Skin Infections:
These are the most common skin infections. Streptococcus and staphylococcus are the two main bacteria which cause infections. Following are the list of bacterial infections of the skin. Most of the skin infections are caused staphylococcus aureus bacteria.
Folliculitis: This is an inflammation of hair follicle. As this condition is confined to the inflammation of hair follicles, it is called folliculitis. There are several types of this condition. Hot tub folliculitis is among them. It is caused by pseudomonas aeroginosa bacteria.
Erisipelas: It is also called St.Anthony’s Fire. This is a staph infection. The infected area appears to be red and swollen with shiny patches. These patches can be differentiated easily from the normal skin. People with this infection experience excruciating pain at the affected areas.
Furuncle: Furuncle afflicts major area known as pilosebaceous units. These units include pili muscle, the sebaceous gland, hair shaft and hair follicle. The armpits, buttocks, neck and face are the most commonly affected areas. Carbuncle is another severe form of furuncle infection. This is a serious form because it is a group of closely formed furuncles.
Cellulitis: Cellulitis is a bacterial infection which affects deeper skin layers including the dermis and subcutaneous tissue. The person experiences chills, fever and fatigue as the infection begins at the deeper skin layers before appearing on the skin. Cellulitis appears to be red and swollen and also very painful. Neck and head are the most affected areas in children with this infection, while in adults it appears on legs and arms.
Impetigo: Impetigo is another staph skin infection. This afflicts the upper layer of the skin or epidermis. One can observe minor breaks like an insect bite or a small cut on the affected area. Non-bullous and bullous are the categories of impetigo. The most common form is non-bullous impetigo, which appears on limbs and face. The infected region appears red with yellow colored crusts under it.
Erythrasma: Erythrasma is a bacterial infection. Often, it is confused with fungal infection due to its appearance. Initially, infected area appears in pink color with well-defined borders which helps in distinguishing with the normal skin. Later, the affected skin blends to normal skin color. Mostly, this infection develops in the areas like groin, armpits and last two toe fingers.
Fungal Skin Infections:
Fungi cause fungal infections which stay in the body. They are not problematic, but in some cases they cause infections in some body areas because of several infections. Fungus grows more in warm and moist areas. Following is the list of various fungal infections of skin.
Jock itch: Tinea cruris or jock itch is caused by a fungus known as tinea. This skin rash appears in the shape of a ring and in red color. This infection develops in warm and moist areas of the body like inner thighs, buttocks and genitals. Burning and itching in groin and thigh and redness of skin are the signs of jock itch.
Athlete’s foot: Athlete’s foot is the most common fungal infection. This infection occurs on feet. This infects men more compared to women. Athlete’s foot is observed in people wearing tight-fitting shoes. Vesicular, interdigital and moccasin are the three types of this infection. Among these three, interdigital infection is the common infection.
Ringworm: This is a contagious fungal infection. It must not be confused with the worm. The skin appears red and circular sore with scaly patches. These scaly patches can be observed on various body parts.
Tinea Versicolor: Tinea Versicolor is a superficial infection which afflicts epidermis or uppermost layer of the skin. This infection is caused by pityros porum orbiculare and pityrosporum yeasts. These can be identified with hyperpigmentation or hypopigmentation around the afflicted areas.
Yeast Infections of the Skin:
Yeast can cause infections in various body parts. Following are different types of yeast infections which occur in various areas.
Vaginal Yeast Infection: This is the most common skin infection and is often observed in women. This can cause pain, itching and discharge in vagina. Vaginal candidiasis or monilial vaginitis causes this infection. Weak immune system, hormonal changes, menstruation, unprotected sex, diabetes, pregnancy and birth control pills cause vaginal yeast infection.
Oral thrush: In this type of infection, white patches appear in the mouth. Monilia Albicans cause this infection. The throat and mouth tissues are invaded by the yeast. These infections are seen in the cheek, on the tongue, roof of mouth, lips and gums. If these patches are wiped off from the mouth, it can cause bleeding and ulcer. Esophageal thrush which spreads to esophagus is called esophagitis. This causes intense pain and difficult to swallow water and food.
