Abstract

Abstract: In order to know the bacterial causes of piglet diarrhea in the Qujing area,the study collected 148 samples from 5 farms appearing diarrhea symptoms for bacterial isolation,culture and drug resistance analysis.The results showed that the detection of pathogenic E.coli was 114 strains,the positive rate was 77.03%;Salmonella was 26 strains,the positive rate was 17.57%,mixed infection rate was 17.57%.Pathogenic E.coli and Salmonella were resistant to a variety of clinic medicines.The 97 strains were multidrug resistance in 114 pathogenic E.coli,showing 85.09% of the total number of bacteria;20 of 26 Salmonella were multidrug resistant,showing 76.92% of the total number of bacteria.The results suggested that pathogenic E.coli was major bacterial pathogen which causing piglets diarrhea in Qujing local area,some piglets were secondary infected with Salmonella,two kinds of bacteria had both appeared high resistance,multidrug resistance were more serious.

Key words: piglets diarrhea; E.coli; Salmonella; drug resistance
