Fungal infection

Introduction

Introduction

The disease caused by fungal infection is called mycosis. The highest incidence of candidiasis and dermatophytosis is caused by the fungus of the normal flora of the human body. The infection can be distinguished as: surface infection, skin infection, subcutaneous tissue infection, deep infection and conditions. Sexual infection. Some common conditions of skin fungal infections are body lice, ankles and cutaneous candidiasis due to skin diseases caused by fungal skin infections (fungal types). A skin fungus is a group of microorganisms that cause skin infections. Some fungi, yeast, naturally appear in the human body. Bacterium is an organism of opportunism. When they come into contact with a favorable environment, they grow and infect the upper layers of the skin as well as nails or hair.

Pathogen

Cause

The fungus (fungus) belongs to the plant kingdom and the fungus gate. It has no structure of roots, stems and leaves, so it cannot use inorganic substances for photosynthesis. It can only live in parasitic life or saprophytic life. Except for a few single cell groups, most of the fungi have branched or unbranched mycelia, which can be sexually or asexually propagated.

Fungi are suitable for breeding in a humid, warm environment. Under the conditions of aerobic, suitable temperature and certain humidity, the fungus floating in the air increases. Therefore, the occurrence of fungal allergies also has regional and seasonal characteristics. Generally, in summer, especially in the mildew rain season, the incidence of fungal allergies increases. But its regional and seasonal characteristics are not as clear as hay fever. For example, in the winter, overheated rooms or workshops, especially humidified, the amount of fungi in the air is also large, and can also form a peak of popularity. Fungal infections are mainly endogenous infections (such as Candida albicans), as well as exogenous infections (such as Aspergillus), such infections and body resistance, decreased immunity and colony disorders.

1. Inquire about the history of trauma and surgery, the time of injury, the location, the treatment after injury, the onset time, the development of the disease, the history of vaccination against tetanus, and the female patient should consult the history of childbirth or abortion, such as For newborns, the history of childbirth and umbilical cord management should be asked. There were a few cases with no history of injury and no obvious wounds.

2, check the injured part, the wound situation, the muscles around the wound are sputum and twitching, paying special attention to whether the rectus abdominis is strong. If there is exudate or exfoliated tissue block in the wound, bacteriological examination (including smear and anaerobic culture) and pathological examination should be performed.

3, to observe whether the patient has closed teeth, paroxysmal convulsions, sneer, angulation, generalized tonic and paroxysmal spasm, pay special attention to whether the airway is smooth, with or without throat. After the patient is quiet, check for pulmonary complications and necessary auxiliary examinations.

Diagnosis

Differential diagnosis

Bacterial infections

After the bacteria invade the host organism, the process of growth and reproduction, release of toxic substances and causing different degrees of pathological reactions of the body become bacterial infection or infection. Viral infections can cause parasitic growth in the human body and infectious diseases caused by pathogenic viruses. Mainly manifested as fever, headache, general malaise and other symptoms of systemic poisoning and local symptoms caused by inflammatory damage caused by viral hosts and invading tissues and organs.
