Detection of ESBLs from Salmonella

Objective: To analyse the producing ESBLs bacterial type of salmonella, in the food stalls of the personal managers in Shijiazhuang,in order to establish an effective therapy measure to prevent the bursting and disseminating of the infection in hospital. Method: To examine the producing ESBLs by Etese method and observe the sensitivity of fifteen antibiotics from fifty-five sera types of salmonellas which be separated from the infected crowd in Shijiazhuang. Result: There was nine kinds of salmonellas, which could produce ESBLs, the main infecting bcteria types were distributed in nine sera groups and fiftyfive sera types. Conclusion: The salmonella 's resistant to drug in Shijiazhuang is serious. The salmonellas producing ESBLs of is more sensitive to neomycin and streptomycin. All the salmonellas were nearly sensitive to gentamicin and nalidixic acid.
