Streptococcus infection

Introduction to streptococcal infection Streptococcus bacteria invade diseases caused by the human body. Divided into two categories: one is infectious diseases, such as acute tonsillitis, pyoderma, pneumonia, etc.; the other is allergic diseases, such as acute glomerulonephritis and other streptococcal infections are common diseases in humans, not only throughout All over the world, and all seasons can happen. basic knowledge The proportion of illness: 0.001% Susceptible people: no crowds Mode of infection: non-infectious Complications: acute renal failure, heart failure, hypertensive encephalopathy

Causes of streptococcal infection

Streptococcus disease is closely related to the reduction of the body's defense ability, the occurrence of allergic reactions, the number of infected bacteria, and the relationship between the toxins and enzymes produced by them.

Streptococcal infection prevention

Enhance physical fitness, improve body defense function, maintain environmental sanitation, reduce upper respiratory tract infection, angina, tonsillitis and other diseases, pay attention to clean, reduce the occurrence of pyoderma, should be actively treated when the above diseases occur.

Streptococcal infection complications Complications acute renal failure heart failure hypertensive encephalopathy

Often complicated by heart failure, hypertensive encephalopathy, acute renal failure.

Streptococcal infection symptoms common symptoms fatigue anorexia nausea vomiting low back pain oliguria

1. History of upper respiratory tract or skin infection 2 to 3 weeks before the disease. Such as pharyngitis, tonsillitis, impetigo.

2, systemic performance such as fatigue, anorexia, nausea, vomiting, low back pain and headache.

3, hematuria and protein urine color is as deep as washing water, light to moderate proteinuria.

4, oliguria and edema urine volume can be less than 400ml / d, morning eyelid edema, pale, "nephritis face", severely affected the whole body, early acupressure depression is not obvious.

5, transient mild to moderate hypertension.

6, acute cases of early left heart failure, encephalopathy and acute renal failure.

Streptococcal infection check

Determining the diagnosis depends on bacterial culture positive (from blood, cerebrospinal fluid, urine, local lesions), while positive skin and mucous membranes only indicate bacteria.

In recent years, the antigen diagnosis of bacteria has progressed rapidly. No matter whether antibiotics or antibiotics have been used, antigen detection methods can be used. Latex agglutination, synergistic agglutination, convective immunoelectrophoresis and enzyme-linked immunosorbent assay are commonly used to accurately convective immunoelectrophoresis. The sample is better, and the sample with less GBS content is superior to the antigen detection bacterial culture.

Elevated specific GBS antibodies may suggest a recent GBS infection, anti-streptolysin O (ASO) and anti-deoxyribonuclease B (DNAse B) only help the diagnosis of GAS, not applicable to GBS.

X-ray examination should be routinely performed to understand the heart, lung condition, electroencephalogram, electrocardiogram examination, brain CT examination if necessary, B-ultrasound and other examinations.

Diagnosis and identification of streptococcal infection

Mainly based on the prevalence of streptococcal infection and patient contact history and characteristic clinical manifestations. Some can only be diagnosed according to their clinical manifestations, such as erysipelas; some need to be cultured in the secretions and blood of the infected part to confirm the diagnosis; detection of bacterial toxins and enzymes and other antigenic substances to cause related antibodies, such as anti-chain Serological tests such as colistin O and anti-chain enzymes are helpful for diagnosis.
