Causes of streptococcal infection

In addition to the reduction of human defense ability, the occurrence of allergic reactions, and the number of infected bacteria, streptococcal disease is also closely related to the toxins and enzymes it produces.

Clinical manifestations of streptococcal infection

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

2. Systemic manifestations such as fatigue, anorexia, nausea, vomiting, low back pain and headache.

5. Transient mild to moderate hypertension.

6. In severe cases early manifestations of acute left heart failure, encephalopathy and acute renal failure may occur.

Diagnosis of streptococcal infection

It is mainly based on the prevalence of streptococcal infection and patient contact history and characteristic clinical manifestations. Some can be diagnosed only based on their clinical manifestations, such as erysipelas; others require bacterial culture of the secretions and blood from the infected site to confirm the diagnosis; detection of antigens such as bacterial toxins and enzymes that cause patients to produce relevant antibodies such as anti-chain Serological tests such as cocci hemolysin O and anti-streptase are very helpful for diagnosis.

Streptococcal infection treatment

Bed rest during the acute phase, easy to digest food, symptomatic treatment such as infusion if necessary. The most important thing is to immediately give a sufficient amount of antibacterial drugs. Penicillin can be selected. People who are allergic to penicillin can switch to erythromycin and lincomycin. For neonatal meningitis patients, the effect of high-dose penicillin or ampicillin is more effective. it is good. Regardless of the drug chosen, the course of treatment should not be less than 10 days.
