Gastrointestinal infections

Gastrointestinal infections

Gastrointestinal infections (GI) are caused by microorganisms such as bacteria, viruses, or parasites in the human digestive tract. These disease causing microbes can enter your body through contaminated food or water, and can quickly pass from one person to another. Initially, these microbes may be initially confined to the human gut, but can quickly spread to others through the fecal-oral route, causing nausea, abdominal pain, vomiting, and severe diarrhea.
Gastrointestinal infections are one of the major causes of morbidity globally and is the second leading cause of death in children under the age of 51. Some of the most common GI tract symptoms are caused by pathogens such as:

Some of the most common GI tract symptoms are caused by pathogens such as:

  • Salmonella
  • Shigella
  • Campylobacter
  • Escherichia coli (E. coli)
  • Clostridium difficile (C. difficile)
  • Norovirus
  • Rotavirus
  • Hepatitis A
  • Cryptosporidium
  • Cyclospora
  • Giardia lamblia

Innovative Gx Laboratories introduces multiplex molecular diagnostic gastrointestinal testing that both detects and identifies numerous GI pathogens in one comprehensive test. Our advanced PCR-based technologies combine same-day delivery of patient results (from receipt at our laboratories) with high levels of sensitivity, specificity, and accuracy of molecular detection. The IGx Gastrointestinal Pathogen Test detects:


  • Campylobacter jejuni, Campylobacter coli, Campylobacter upsaliensis
  • Clostridioides (Clostridium) difficile, toxin A/B
  • E. coli O157
  • Plesiomonas shigelloides
  • Salmonella enterica
  • Shiga Toxin-Producing E. coli
  • Shigella sonnei, Enteroinvasive E. coli (EIEC)
  • Vibrio cholerae
  • Vibrio vulnificus, Vibrio parahaemolyticus
  • Yersinia enterocolitic


  • Cryptosporidium parvum
  • Cyclospora cayetanensis
  • Cystosiospora belli
  • Entamoeba histolytica
  • Giardia lamblia


  • Carbapenemase and Metallo-Betalactamase Resistance Class A and C Beta-lactams resistance
  • Class A and Plasmid ESBL Resistance
  • Class C Beta-lactams resistance
  • Class D Betalactamase Resistance
  • Dihydrofolate and Sulfonamide Resistance
  • Quinolone Resistance
  • Tetracycline Resistance


  • Hepatitis A
  • 1 WHO
  • Norovirus GI/GII
  • Rotavirus
  • Sapovirus, Astrovirus

A successful treatment approach of gastrointestinal infections and containment of pathogens begins by rapidly and accurately identifying all pathogens present in the infection, including any antibiotic resistance. Eliminate the guesswork and determine which antibiotic will be effective in the treatment of gastrointestinal infections and prevent the spread to others.
