AB - To explore the pathogenic mechanism of Salmonella, serotype
was identified and enterotoxin gene stn was detected for 47 strains suspected
Salmonella in the Eastern part of Hebei Province. According to the bacterial
culture characteristic, physicochemical properties and analysis results of K-3401
semi automatic bacteria identification instrument and identification for another
time by Chengdu Institute of Biological Products, enterotoxin gene stn
was detected by PCR. The 17 strains of Salmonella gallinarum, 14 strains
of Salmonella typhimurium, 4 strains of Salmonella pullorum 2
strains of Salmonella paratyphi A, 2 strains of Salmonella group BO,
5 strains of Salmonella bovismorbificans, 3 strains of Salmonella
enteritidis were detected from 47 strains of chicken source of Salmonella.
The 45 strains of stn gene were amplified successfully in all 47 strains.
The carrying rate was 95.7%. Homology of stn gene of test strains of
Salmonella was between 94 and 100%. Evolutionary tree display that different
serotypes of Salmonella enterotoxin stn gene divided into 5 groups. There
was no homology with other bacterium. Chicken source of Salmonella contained
7 kinds of serotypes in the eastern part of Hebei Province. Among them, Salmonella
gallinarum was 36.2% (17/47), Salmonella typhimurium which was advantages
serotypes was 29.8% (14/47). The carrying rate of enterotoxin gene stn
which had relation with bacterial pathogenicity was 95.7% (45/47).
