Actinomycosis is a rare, infectious disease in which bacteria spread from one part of the body to another through body tissues. Over time, it can result in linked abscesses, pain, and inflammation. Many people have actinomycosis bacteria in their body, but the bacteria usually stay in one place and do not cause disease in healthy tissues. If damage occurs in the area around where the bacteria live, due to injury or trauma, the bacteria can move to other areas. As the condition progresses, the deep tissue can become inflamed and pus-filled.
What are the symptoms of MRSA?
Millions of Americans develop serious infections each year from drug-resistant staphylococcus bacteria. MRSA infections originally appeared mostly in hospitals and nursing homes. A virulent kind of resistant "staph" has developed outside of health care settings. It's known as community-acquired MRSA. MRSA infections generally begin as skin infections. For children, the most common source of infection is a simple cut or abrasion. If caught early, a MRSA infection is usually easy to treat. It's important to seek medical treatment for your child immediately if you notice any symptoms, because the infection can rapidly become serious if it's not treated right away.
When to seek medical care
When bacteria infect a hair follicle or oil gland, a red, painful, pus-filled bump can form under the skin. This is known as a boil. A boil is usually very painful because of the pressure that develops as it grows bigger.
A comedo is a clogged hair follicle pore in the skin. The chronic inflammatory condition that usually includes both comedones, inflamed papules and pustules pimples is called acne. Comedo-type ductal carcinoma in situ DCIS is not related to the skin conditions discussed here. DCIS is a non-invasive form of breast cancer, but comedo-type DCIS may be more aggressive and so may be more likely to become invasive. Oil production in the sebaceous glands increases during puberty, causing comedones and acne to be common in adolescents. Oxidation rather than poor hygiene or dirt causes blackheads to be black. Some, but not all, skin products might increase comedones by blocking pores,  and greasy hair products like pomades can worsen acne. A hair that does not emerge normally, an ingrown hair , can also block the pore and cause a bulge or lead to infection causing inflammation and pus.
