Abstract:
ObjectiveTo determine the pathogens and drug resistance in patients with bacterial diarrhea in Lishui City of Zhejiang Province from 2015 to 2019， and provide scientific evidence for prevention and treatment of bacterial diarrhea. MethodFecal specimens were collected from patients with diarrhea in the People’s Hospital of Lishui City from 2015 to 2019. Bacteria were identified by time-of-flight mass spectrometer and serum agglutination reaction. Drug sensitivity in the suspected bacteria was identified by VITEK 2 Compact system. ResultsA total of 2 937 fecal samples were tested from 2015 to 2019， of which 191 were positive for bacteria. The prevalence was 6.65% in male and 6.32% in female. It was highest in the age group 21‒30 years old， followed by the group 51‒60 years old. Summer was the season with the highest prevalence of bacteria. Furthermore，the bacterial species included salmonella （3.98%）， Vibrio parahaemolyticus （1.43%）， aeromonas （0.48%）， shigella （0.37%） and other bacteria （3.66%）. Salmonella had high resistance to cefuroxime and amikacin. Vibrio parahaemolyticus and shigella had high resistance to ampicillin. Aeromonas had high resistance to ampicillin and ampicillin/sulbactam. ConclusionPrevalence of bacteria differs by gender， age and seasons in patients with bacterial diarrhea in Lishui from 2015 to 2019. Salmonella is the principal pathogen in bacterial diarrhea. Additionally， multiple drug resistance is commonly identified. Therefore， it warrants strengthening the pathogenic surveillance on bacteria and drug resistance in bacterial diarrhea.
