INTRODUCTION
Salmonella enterica serotype Kentucky was isolated from septic poultry in Nigeria. The objective of this study was to characterize this isolate by screening for SGI1 and hyper-virulence.
METHODOLOGY
The strain was characterized by identification of Salmonella genomic island 1 (SGI1) through a PCR assay and we used a tissue culture invasion assay to assess protozoa-mediated hyper-invasion.
RESULTS
Salmonella genomic island 1 (SGI1) was identified in the strain along with an SGI1 gene (SO13) implicated in hyper-virulence. Protozoa-mediated hyper-invasiveness was also documented in the strain.
CONCLUSION
The hyper-invasion is concordant with this emerging strain's ability to cause fowl paratyphoid.
引言
肠炎沙门氏菌肯塔基血清型是从尼日利亚的败血症家禽中分离出来的。本研究的目的是通过筛查SGI1和高毒力来鉴定该分离株。
方法
通过PCR检测鉴定沙门氏菌基因组岛1（SGI1）对该菌株进行特征分析，并使用组织培养侵袭试验评估原生动物介导的高侵袭性。
结果
在该菌株中鉴定出沙门氏菌基因组岛1（SGI1）以及与高毒力相关的SGI1基因（SO13）。该菌株中也记录到了原生动物介导的高侵袭性。
结论
高侵袭性与这种新出现的菌株引起禽副伤寒的能力一致。
