项目摘要
Project Summary/Abstract:
This comparison study is intended to compare Sensititre™ Vet AST COMPGP1F/COMPGN1F
plates to bioMérieux Vitek® AST-GP81/AST-GN96 cards for performance of antimicrobial
susceptibility testing (AST) results. This method comparison will be performed on common
bacterial companion animal pathogens such as Escherichia coli, Enterococcus species,
Staphylococcus pseundintermedius, Pseudomonas aeruginosa, and other Enterobacterales
isolates. These bacterial pathogens may be shared between companion animals and humans;
therefore, antimicrobial resistance (AMR) of these isolates is a critical concern. AST results on
companion animals are significant for prediction of treatment outcome and are valuable
comparisons to AMR trends occurring in humans. Although widely used in veterinary
microbiology, AST plates manufactured by the currently dominating vendor, Sensititre™, are
lacking the necessary range of antimicrobials to adequately detect common resistance
mechanisms which would allow for appropriate comparison to AMR trends occurring in humans.
The bioMérieux Vitek is commonly used in human microbiology laboratories; AST cards
designed for this system incorporate ranges of antimicrobial concentrations of clinical and
epidemiological interest for key indicators of antimicrobial resistance. Although the
manufacturer has products designed for veterinary use, few laboratories in the United States use
the bioMérieux Vitek instrument for AST. To date, there are no published studies comparing
Sensititre™ AST to bioMérieux Vitek. Findings of this methods comparison will be published,
which will provide objective data that veterinary diagnostic laboratories can use to determine
which method is most appropriate for their laboratories. This comparison study will enhance
AMR surveillance capabilities of the NDSU VDL and will directly support Vet-LIRN initiatives
of protecting public health. This study may identify a reliable and affordable second vendor for
AST in veterinary microbiology, which also ensures that all vendors continue offering useful
veterinary products and encourages routine improvements of products offered to veterinary
diagnostic laboratories.
项目概要/摘要:
本比较研究旨在比较Sensititre ™ Vet AST COMPGP 1F/COMPGN 1F
将平板与bioMérieux Vitek® AST-GP 81/AST-GN 96药敏卡进行比较,以确定抗菌性能
药敏试验(AST)结果。该方法比较将在常见的
细菌性伴侣动物病原体如大肠杆菌,肠球菌属,
假中间葡萄球菌、铜绿假单胞菌和其他肠球菌目
分离株这些细菌病原体可能在伴侣动物和人类之间共享;
因此,这些分离株的抗菌素耐药性(AMR)是一个关键问题。AST结果
伴侣动物对于预测治疗结果具有重要意义,
与人类发生的AMR趋势进行比较。虽然广泛用于兽医
微生物学方面,目前主要供应商Sensititre ™生产的AST平板,
缺乏必要的抗菌剂范围以充分检测常见耐药性
这些机制允许与人类中发生的AMR趋势进行适当比较。
bioMérieux Vitek常用于人体微生物实验室; AST卡
为该系统设计的抗菌剂浓度范围包括临床和
流行病学兴趣的抗菌素耐药性的关键指标。虽然
制造商有专为兽医使用的产品,在美国很少有实验室使用
bioMérieux Vitek AST仪器。到目前为止,还没有发表的研究比较
Sensititre ™ AST至bioMérieux Vitek。将公布这一方法比较的结果,
这将为兽医诊断实验室提供客观数据,
哪种方法最适合他们的实验室。这项比较研究将提高
NDSU VDL的AMR监测能力,并将直接支持Vet-LIRN计划
保护公众健康。这项研究可以确定一个可靠和负担得起的第二供应商,
AST在兽医微生物学,这也确保了所有供应商继续提供有用的
兽医产品,并鼓励对提供给兽医的产品进行常规改进
