Objective To understand the pathogenic spectrum compositionof bacterial diarrhea in Jiangxia District of Wuhan, to explore thevariation and epidemic changes of the main pathogenic bacteria inJiangxia District of Wuhan in recent years, and to provide scientificbasis for the diagnosis and prevention and control of bacterialdiarrhea. Methods 341 specimens of patients with bacterial diarrheasyndrome in Jiangxia District of Wuhan from 2021 to 2023 were collected,and a variety of intestinal pathogenic bacteria were detected, and thedrug resistance of the detected pathogenic bacteria was analyzed. Results The highest detection rate in 2021-2023 was Salmonella,accounting for 42.82%(146/341) of cases detected; next is Vibrio, with adetection rate of ${16.42}\%\left({{56}/{341}}\right)$ ; thethird place is Escherichia coli, with a detection rate of 6.74%(23/341).In the typing results, the most commonly detected strains of Salmonella,Vibrio, and Escherichia coli were Salmonella enterica, Vibrioparahaemolyticus, and pathogenic Escherichia coli, with detection ratesof 14.37%, 13.20%, and 3.52%, respectively. Among the 341 detectedbacteria, the age group of 20~40 had the highest number of detectedbacteria, with 223, accounting for 65.40% of the total; 118 strains weredetected in the age group of 40~60, accounting for 34.60% of the total.There is a statistically significant difference between the two agegroups $\left({{\chi }^{2}= {57.484}, P<{0.001}}\right)$ . Conclusion Salmonella is the main pathogenic bacteria of bacterial diarrhea in Jiangxia District of Wuhan from 2021 to2023.
