Characteristics
Morphology Gram negative microaerophilic curved rod.
Disease

H. pylori are not invasive, but colonize in the human stomach's antral region and gastric mucosal surfaces where they release pathogenic proteins that induce cell injury and inflammation. This can result in clinical symptoms of infection, such as duodenal ulcer and gastric adenocarcinoma. Other common illnesses as a result of infection include gastroenteritis, diffuse antral gastritis, and gastric carcinoma. H. pylori is a Class I human carcinogen according to the World Health Organization. Infection can last a lifetime in the host if not properly treated, causing chronic gastritis which can lead to peptic gastroduodenal ulcer disease.

Zoonosis Yes, animals and humans and vice versa.

Risk Group & Containment Requirements
Risk Group 2

Agents that are associated with human disease which is rarely serious and for which preventive or therapeutic interventions are often available.

BSL2
For all procedures involving suspected or known infectious specimen or cultures.
ABSL2
For all procedures utilizing infected animals.
Spill Procedures
Small
Notify others working in the lab. Remove PPE and don new PPE. Cover area of the spill with absorbent material and add fresh 1:10 bleach:water. Allow 20 munutes (or as directed) of contact time. After 20 minutes, cleanup and dispose of materials.
Large
  • Immediately notify all personnel in the lab and clear all personnel from the area. Remove any contaminated PPE/clothing and leave the lab. 
  • Secure the area by locking doors, posting signage and guarding the area to keep people out of the space.
