Fast inspection reagent kit for streptococcus suis 2-type triple PCR

Abstract

The triplex PCR-based rapid detection kit for Streptococcus suis Type 2 which is composed of four cryopreservation tubes containing different components, 100 PCR reaction tubes and the brochure of the detection steps for the cryopreservation tubes. The four cryopreservation tubes contain mixture of 10*buffer, dNTP, primer gdh-1, gdh-2, mrp-1, mrp-2,cps2J-1, cps2J-2 and Taq DNA polymerase; lysis buffer; positive control solution; diluent respectively. The triplex PCR process established in the present invention can amplify gene gdh, mrp and cps2J of SS-2 at the same time and has high specificity. The homology of sequencing is always between 98.84% and 100% exhibiting high accuracy and specificity.

Description

technical field

[0001] The invention belongs to the field of biotechnology and relates to the diagnosis of animal diseases, in particular to a rapid detection kit suitable for SS-2 in the pure culture of suspected Streptococcus suis type 2 (SS-2) and tissue samples, i.e. suis chain Coccus Type 2 Triple PCR Rapid Detection Kit. Background technique

[0002] Streptococcus suis (SS) can be divided into 35 serotypes according to the difference of capsular antigens, namely 1-34 and 1 / 2. Among them, Streptococcus suis type 2 (SS-2) not only has the characteristics of strong pathogenicity and wide prevalence, but also can cause human infection and death. As early as 1968, Denmark reported the first case of meningitis caused by human infection with Streptococcus suis. In my country, SS-2 infection occurred successively in Jiangsu Province in 1998-1999 and in Sichuan Province in 2005, leading to the death of pigs and humans. The rising trend of suis streptococcal infection and its...
