There is no such thing as a nemesis for bacillary dysentery. Timely antimicrobial treatment usually has a good prognosis. Bacterial dysentery is a kind of intestinal infectious disease caused by Shigella bacillus infection, the patient will have abdominal pain, diarrhea, bloody stools, anxiousness (lower abdominal discomfort, want to defecate very much, and after the bowel movement has a feeling of incomplete) and other symptoms, need to comply with the doctor’s instructions for antibacterial treatment. Quinolone antibiotics such as levofloxacin and norfloxacin are preferred for bacterial dysentery. For those who are resistant to quinolones or with unsatisfactory results, sensitive antibiotics can be selected for antibacterial treatment through bacterial drug sensitivity test. Acute common and mild bacillary dysentery can be cured in about 1 week after antimicrobial treatment, and a few of them will be transformed into chronic or carriers, at this time, it is necessary to use two different types of antibiotics in combination for a sufficient amount of antibiotic treatment with a long course of antimicrobial treatment. Acute bacillary dysentery, if left untreated, has the risk of developing into acute toxicity or chronic bacillary dysentery, and because it is contagious, it is advisable to consult a doctor and isolate the patient in order to avoid adverse effects.
