What categories are included in bacterial skin diseases

Bacterial skin diseases cover a lot of content. They refer to skin diseases caused by bacterial infection. There are many bacteria that cause this skin disease, and the symptoms caused are also diverse. For example, they can cause sepsis, scarlet fever, meningitis, abscesses and other skin diseases. When you first encounter bacterial skin diseases, it is important to promptly diagnose the cause and then receive regular treatment.

(1) Classification by bacterial species

Can be divided into coccal and bacillary skin diseases. Coccal infectious skin diseases are caused by pyogenic cocci and are referred to as pyoderma. Common ones include impetigo, furuncle, folliculitis, meningococcal rash, scarlet fever, sepsis, toxic shock syndrome, etc. The skin diseases caused by bacilli mainly include cutaneous tuberculosis and leprosy, and others include typhoid fever, paratyphoid fever, anthrax, erysipelas, plague, etc.

(2) Classification by disease course

It can be divided into acute and chronic types. Most bacterial, especially coccal, skin diseases are acute and have a short course. Only a few, such as skin tuberculosis and leprosy, are chronic processes.

(3) Classification by pathogenesis

It can be divided into direct pathogenicity, indirect pathogenicity or both. Direct pathogens such as folliculitis, furuncle, impetigo and some tuberculous rashes are lesions directly caused by bacteria at the site of invasion; indirect pathogens such as scarlet fever, toxic shock syndrome and most tuberculous rashes are mainly caused by allergic reactions (allergic to bacterial products) or poisoning reactions (damage caused by bacterial toxins). However, clinical situations are complex and the disease is changeable. Direct or indirect causes of disease are not absolute and should be analyzed based on specific circumstances.
