non-cholera vibrio infection
Introduction
Introduction to non-cholesteric infection Infection caused by non-V. cholerae, which is different from Vibrio cholerae in biochemistry and serology, can cause wound infection, intestinal toxicity or diarrhea due to different pathogenic bacteria. Should be differentiated from cholera, bacterial dysentery, etc. Avoid eating contaminated or non-fresh foods. High-risk patients with skin wounds should avoid the operation of unburned seafood and contact with seawater, which can play an active preventive role. basic knowledge The proportion of illness: the incidence rate is about 0.006% - 0.007% Susceptible people: no special people Mode of infection: digestive tract spread Complications: shock
Cause
Causes of non-cholesteric Vibrio infection
Cause:
Food-borne diseases, mostly caused by the inclusion of non-cholesteric Vibrio such as Vibrio parahaemolyticus, Vibrio mimicus, Vibrio alginolyticus, Vibrio cholerae, Vibrio vulnificus and so-called non-aggregating Vibrio, parahemolytic Food such as Vibrio.
Prevention
Non-cholesteric infection prevention
Avoid eating contaminated or non-fresh foods. High-risk patients with skin wounds should avoid operating unburned seafood and contact with seawater. When diarrhea, pay close attention to blood volume and electrolyte loss. For patients with necrotizing fasciitis, in addition to antibiotics, surgical debridement should also be performed.
Complication
Non-cholesteric bacterium infection complications Complications
1. Water and electrolyte metabolism disorders.
2. Shock.
Symptom
Symptoms of non-cholesteric infections Common symptoms Diarrhea, urgency, fatigue, watery stool, low abdominal fever
After a period of 15 to 24 hours of incubation, the disease begins to acutely attack, with abdominal pain, watery diarrhea (large can be bloody and contains polymorphonuclear leukocytes), urgency, weight, fatigue, and sometimes low fever. Symptoms resolve spontaneously after 24 to 48 hours Non-aggregating Vibrio can cause cholera-like diseases and can be isolated from wounds and blood. Wounds infected by warm seawater can evolve into cellulitis, and some cases can rapidly deteriorate into necrotizing fasciitis with typical hemorrhagic and bullous lesions. Vibrio vulnificus is damaged host (often with liver disease or immunity) Defective) After ingestion, it can pass through the intestinal mucosa without causing enteritis, but can produce sepsis with high mortality.
Examine
Non-cholesteric infection detection
The feces were cultured with thiosulfate-citrate-bile-sucrose perfusate to isolate pathogenic Vibrio. Contaminated seafood for cultivation.
Diagnosis
Diagnosis and identification of non-cholesteric Vibrio infection
It can be diagnosed based on medical history, clinical symptoms and laboratory tests.
Should be differentiated from cholera, bacterial dysentery, etc.
