Identifying the Causes of Gastroenteritis

Gastrointestinal (GI) Infections

From our most advanced syndromic approach to our traditional methods, bioMérieux has comprehensive diagnostic solutions to help clinicians identify GI pathogens causing gastroenteritis, making it easier to treat patients and improve outcomes.

What is a Gastrointestinal Infection?

Gastrointestinal infections are viral, bacterial, or parasitic infections that cause gastroenteritis, an inflammation of the gastrointestinal tract involving both the stomach and the small intestine.1,2 Symptoms include diarrhea, vomiting, and abdominal pain. Warning signs include fever, bloody diarrhea, dehydration, and hospitalization. Most gastrointestinal infections are self-limited and resolve within a few days. However, in a healthcare setting and in specific populations (newborns/infants1, immunocompromised patients3, elderly populations, and travelers), they can be potentially serious and difficult to treat. In addition, some GI infections can lead to outbreaks. Rapid diagnosis, appropriate treatment, and infection control measures are therefore particularly important in these contexts.

What is the healthcare burden of Gastrointestinal Infections?

Gastrointestinal infections are among the most encountered infections in primary care.4

  • > 200 million episodes/year of infectious gastroenteritis in US5
  • Worldwide 3-6 million children die each year from infectious gastroenteritis6
  • Outbreaks of gastrointestinal infections are a serious concern in the hospital environment7

Additionally, several gastrointestinal pathogens cause similar, overlapping symptoms, which makes it difficult for clinicians to determine the right tests to perform. In the case of patients with Inflammatory Bowel Disease (IBD), similar clinical presentations and laboratory findings in IBD relapse and enteric infections pose barriers to accurate diagnosis and treatment.8 In both cases, traditional methods of pathogen identification can be time consuming and lack sensitivity, prolonging time to accurate diagnosis. 

Among the gastrointestinal pathogens, Clostridioides difficile (C.difficile) is one of the leading causes of acute gastroenteritis and one of the most challenging healthcare associated infections. It is highly transmissible, specifically because its spores survive for long periods of time outside the body, which also makes it difficult to treat. C. difficile infection (CDI) generates costly treatment, patient isolation, and longer hospital stays.9  

Time-consuming and labor-intensive processes that lead to low diagnostic yield combined with the ongoing threat of C. difficile create a significant burden on our healthcare systems.

What is Our Solution for Gastrointestinal Infection Diagnosis?

It is imperative that clinicians are armed with the right tests to efficiently and accurately diagnose the infection. Fortunately, our BIOFIRE® FILMARRAY® Gastrointestinal (GI) Panel provides fast, accurate answers on a comprehensive menu, enabling hospitals and clinics to test for 22 possible pathogens in one fast and accurate test— giving patients concrete answers while providing clinicians the results they need to make timely, targeted treatment decisions ultimately reducing antibiotic delays, length of hospital stays, and unneeded downstream procedures.

Our traditional VIDAS® automated tests improve the efficiency and accuracy of serological diagnosis performed on stool samples. And, our culture media range is composed of various formulas to help detect the right pathogens contributing to gastrointestinal infections. The CHROMID® range for GI infection has been designed to more specifically highlight Salmonella spp., Campylobacter spp., Vibrio spp., and C. difficile.
