Hyalomycosis

Introduction to Fusarium oxysporum Hyalohyphomycosis is a group of infectious diseases characterized by histologically transparent hyphae caused by non-dark-colored fungi. It is generally invisible to HE staining. Red or black can only be seen in PAS or silver staining. Hyphae. In 1982, Ajello and McGinnis proposed the name of the disease corresponding to the genus Mortierella. The significance of these two disease names is that they can constantly accommodate new pathogenic fungi without the need to establish a disease name for each new strain, but have been named with pathogens and the original name is still used by a wide range of users such as aspergillosis. basic knowledge The proportion of illness: 0.04%-0.05% Susceptible people: no specific population Mode of infection: contagious Complications: sepsis sepsis and bacteremia

Cause of Sclerotinia sclerotiorum

Fungal infections (30%):

Caused by infections caused by non-dark color fungi, from 1982 to 1998, pathogens have reached 27 genera, 69 strains, including the more common penicillium, Fusarium, Geotrichum, Pseudomonas, and creases. Bacteria, gray cobweb, Acremonium, Trichoderma, Beauveria bassiana, Fusarium, Paecilomyces, Trichoderma, Acremonium, Trichoderma, Rhododendron, Chrysosporium, Orange Mildew, common Penicillium, Penicillium sinensis, etc., the mycological classification belongs to Ascomycota.

Pathogenesis

Skin infections may be invasive plaques, abscesses, ulcers and granulomatous lesions. When developed into subcutaneous tissue, they may manifest as cysts, abscesses, granuloma lesions. The course of the disease is chronic and generally not easy to develop into invasive diseases.

Sclerotinia sclerotiorum prevention

1. Strengthen physical exercise, strengthen nutrition, and enhance the body's ability to resist disease can prevent the occurrence of this disease.

2. Avoiding entry into the epidemic area is one of the effective measures to prevent this disease.

Helicobacter pylori complications Complications sepsis sepsis and bacteremia

The disease is usually accompanied by itching. Because the integrity of the skin is damaged, it can cause skin bacterial infection or fungal infection due to scratching. It is usually secondary to low constitution, or long-term use of immunosuppressants and fungal infections such as onychomycosis. Such as concurrent bacterial infections may have fever, skin swelling, ulceration and purulent secretion and other performance. Severe cases can lead to sepsis, which should be brought to the attention of clinicians.

Symptoms of Fusarium oxysporum Common symptoms Skin and soft tissue infections Granuloma abscess cyst

The manifestations of the disease can be further divided into skin, subcutaneous and systemic infections. Skin infections can be invasive plaques, abscesses, ulcers and granulomatous lesions. When developed into subcutaneous tissue, they can manifest as cysts, abscesses, granulomatous lesions, The course of the disease is chronic, and it is generally difficult to develop into an invasive disease, but when the patient's resistance is low, the whole body can be spread, causing systemic infection.

Examination of hyaltridin

Mycological examination: a large number of transparent hyphae and spores can be seen in the pus or tissue fluid at the lesion. The fungal culture varies with the pathogen species, and colonies of various forms and colors appear.

Histopathology: HE staining showed tuberculous granulomatous lesions, and caseous necrosis was observed. A number of magenta or black hyphae and spores were observed in PAS or GMS staining.

Diagnosis and identification of Sclerotinia sclerotiorum

According to clinical manifestations, mycological examination and histopathological examination can be diagnosed, and the latter can be diagnosed by PAS or silver staining.

The disease is mainly differentiated from other fungal infections and patients with similar clinical manifestations, such as chronic infectious skin ulcers and skin tuberculosis.

1. Skin ulcers: usually found after skin damage combined with bacterial infection, treatment is not timely or the medication is not correct caused by infection delay.

2. Skin tuberculosis: Patients with tuberculosis, usually secondary to tuberculosis or bone tuberculosis, are usually secondary to biopsy.
