Abstract:
We investigated serotype and resistance of Salmonella during pig slaughtering in Shandong Province,China,providing basic data for the risk assessment of Salmonella and for guiding the clinical medication.We used rapid classification kit to identify Salmonella serotype,adopted broth microdilution method to detect the resistance of 13 kinds drugs belong to 8 categories.Result showed that the identified 9 kinds of serotype were mainly S.derby and S.typhimurium.The resistance to 13 kinds drugs of 298 Salmonella were different.The higher percentage of tetracycline drugs as Doxycycline(DOX) and Tetracycline(TE) were 97.99％ and 80.20％,respectively,which was most sensitive to Colistine E.The resistant rate was only 2.01 ％,following by Amoxicillin/Clavulanic acid and Ofloxacin which were 2.35 ％ and 4.03％,and the multiple resistant rate was 81.88％.TE-DOX was the regnant drug-resistant spectrum.In conclusion,the predominant serotype of Salmonella in links of pig slaughtering in Shandong Province is S.derby,and resistance is different to the different drugs.The drug resistance of different slaughter links exist significant differences,multiple drug resistance is serious,and drug-resistant spectrum are varied.
