Protocol for detecting Helicobacter suis infection in gastric biopsies and serum by PCR and ELISA

Summary: Infection with Helicobacter suis, which causes many cases of gastric disease, is not reliably diagnosed. Here, we present a protocol for detecting H. suis infection. We describe steps for collecting gastric biopsies and sera from patients, preparing DNA for PCR, and targeting the H. suis-sp...

Description
Summary:Summary: Infection with Helicobacter suis, which causes many cases of gastric disease, is not reliably diagnosed. Here, we present a protocol for detecting H. suis infection. We describe steps for collecting gastric biopsies and sera from patients, preparing DNA for PCR, and targeting the H. suis-specific gene. We then define procedures for inoculating biopsies onto primary agar plates and transferring colonies to secondary agar plates. Finally, we detail whole-genome sequencing of bacteria and assess H. suis infection in sera with ELISA.For complete details on the use and execution of these protocols, please refer to Matsui et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
