What are the bacteria that cause purulent infections?

Bacteria are the biggest cause of harm to the body. They are everywhere in our daily lives, and there are many bacteria that cause purulent wounds. Generally, purulent bacteria can easily lead to infection in body wounds, or rot in body wounds, etc., which are very harmful to the body and need to be treated in time. Pay more attention to body hygiene and cleanliness and keep it dry.

Pyogenic bacteria

Pyogenic bacteria are a type of bacteria that can infect the human body and cause purulent inflammation. It is pathogenic to the human body, often causing purulent infection of the skin, subcutaneous soft tissue, deep tissue and even abscesses of internal organs. Purulent bacteria can also cause sepsis.

Type Introduction

There are many types of purulent bacteria, including cocci and bacilli; Gram-positive bacteria and Gram-negative bacteria; aerobic bacteria, facultative anaerobes and anaerobic bacteria. Generally, pyogenic bacteria that are pathogenic to humans are divided into two categories: pyogenic cocci and pyogenic bacilli. Infections caused by purulent bacteria are clinically important and often cause purulent infections in trauma infections and nosocomial infections.

Etiology and pathogenesis

Purulent bacterial infections are mostly caused by nonspecific purulent bacterial infections invading wounds, followed by complications caused by trauma, such as bedsores, pneumonia, urinary tract infections, etc.

1. Wound contamination. Trauma forms wounds, and dirt is brought into the wound from the outside. If the wound is not cleaned thoroughly or treated in time, it will cause infection.

2. Weakness of vital energy and trauma often cause blood loss, pathological changes in qi and blood, and changes in organ function. The body's vital energy declines, allowing evil to take advantage of the opportunity to enter.

3. Blood stasis turns into heat and toxins accumulate to form pus. Trauma causes blood stasis in tissues or internal organs. A large amount of blood stasis accumulates and turns into heat over time. Severe heat causes flesh to rot, and rotten flesh turns into pus.

4. When evil poison invades the body and forms wounds, when the fire poison is strong and accumulates into pus, and the vital energy is weak, the evil poison can invade the internal organs.

Diagnostic Methods

Syndrome differentiation and diagnosis of purulent bacterial infection

1. Diagnosis points

(1) Medical history: Generally, there is a history of trauma, and the wound is contaminated by foreign objects.

(2) Clinical manifestations: ① Local manifestations: local redness, swelling, heat, pain, secretions or pus in the wound. ② Systemic manifestations: Most patients have obvious fever, thirst, irritability, loss of appetite, yellow urine, constipation, yellow and greasy tongue coating, and stringy or fine pulse. Severe infection may also cause high fever, chills, stupor, delirium, and even coma.

(3) Laboratory examination: ① White blood cell count: The total number is significantly increased, and the number of neutrophils increases. ② Blood culture: When the infection causes bacteremia, bacteria can be cultured.
