Causes of Cellulitis Infection - Basic Description

Our first line of defense and largest organ of body is skin. Surface of skin is never sterile, even when it is clean. That means that human skin is populated with a mixture of microorganisms usually called normal skin flora¹ which creates a active barrier that protects from harmful pathogens at bay. Certain percentage of the general population will be carriers of a pathogen that displaces some of their normal flora (also colonizes locations on our body) at any time. Generally, normal skin flora and colonizing microorganisms do not cause infections and also do not stimulate immune system of organic structure. In case there is a break in the skin or if the immune system becomes compromised,any pathogen can cause cellulitis infection or other type of skin infection.Causes of cellulitis generally may been caused by normal skin flora or by exogenous bacteria, in most cases occurred on area where skin was previously broken (cuts, blisters, burns, cracks in the skin, surgical wounds ,sites of intravenous catheter insertion or other cellulitis causes this type).
Group A streptococcus bacteria is the most generally causes of cellulitis infection in adults with no other medical terms. This bacteria is commonly found on the human skin and in the throat of individuals. Breaks in the skin and problems with the lymphatic system of body which are particular risk factors , can growth individual's chance of developing infection. Cellulitis is skin inflammation caused by bacteria. Although medical advisers are careful of cellulitis causes, they can rarely explain why one individual will become infected and another will stay healthy-difficulties of detecting real causes of cellulitis.

Usual Cellulitis Causes

Probably the most usual cellulitis causes in adults with no particular medical complications is group A streptococcus. This bacteria is common on the skin and in the throat of every person and generally most ordinarily causes of cellulitis.
Second usual cause by grownups is Staphylococcus aureus (S. aureus). This bacteria is commonly found on person's skin and lining of mouth and nose (medically mucosa).

Other Causes of Cellulitis

In special cases, cellulitis causes may been of other bacteria type. When this cellulitis causes happen , usually it's the result of medical condition like HIV,diabetes or AIDS, or because infection affected a very specific body area - other causes of cellulitis.
Other types of bacteria may be cause of cellulits to.Cellulitis causes by youngsters until age of 6, Hemophilus influenza e (H. flu) bacteria is cause of cellulitis infection, most usually on arms, face and upper body. Bite from a dog or cat may be caused by bacteria pasteurella multocida (has very short incubation period 4-24 hours only - danger).Bacterias Aeronomas hydrohilia and Vibrio vulnificus bacteria causes cellulitis infection after exposure to seawater or freshwater. Bacteria pseudomonas aeruginosa may causes of cellulitis after a puncture wound. Other bacteria which can causes of cellulitis are: P. aeruginosa, Vibrio vulnificus, Methicillin-resistant S. aureus (MRSA), Clostridium septicum, Group B streptococcus , E. coli, Erysipelothrix.

¹Microorganisms that live harmlessly on or in the body and do not cause disease unless the normal protective barriers (skin, mucosa) are compromised.
