Identifying Gastrointestinal Viruses, Parasites and Bacteria

 
The Centers for Disease Control estimates that 350 million acute diarrheal illnesses occur annually, and notes that diarrheal syndromes are often similar in presentation. Practitioners frequently encounter complex cases in which co-infections result in the difficult task of identifying the specific cause(s) of the symptoms of acute, or more devastating, chronic illness. Historically, the lack of testing methods that could identify a full range of viruses, parasites, and bacteria has made some GI infections difficult to diagnose – Doctor’s Data now offers a more comprehensive, accurate and rapid solution.

Doctor’s Data has become the leader in world class microbial analysis and gastrointestinal health using state of the science technology and methodologies. The GI Pathogen Profile, employing multiplex PCR technology is the newest test available within our arsenal of clinical Microbiology profiles.

The GI Pathogen Profile, multiplex PCR from Doctor’s Data is capable of the simultaneous detection and identification of 22 specific gastrointestinal pathogenic microbes using FDA-cleared*, multiplex FilmArray PCR technology with up to 98.5% overall sensitivity and 99.3% overall specificity. The identification of the pathogenic viruses, parasites, and bacteria along with a rapid-turnaround time of 24-48 hours significantly expedites clinical decisions and treatment options.
  
The following bacteria (including several diarrheagenic E. coli/Shigella pathotypes), parasites, and viruses are identified using the GI Pathogen Profile: 
 
Bacteria
Viruses
Campylocbacter (C. jejuni/C. upsaliensis)
Clostridium difficile
(toxin A/B)
Pleasiomonas shigelloides
Salmonella
Vibrio (parahemolyticus, vulnificus, cholerae)
Vibrio cholerae
Yersinia enterocolitica

Adenovirus F 40/41
Astrovirus
Norovirus GI/GII
Rotavirus A
Sapovirus (I, II, IV, and V)
Diarrheagenic E. coli/Shigella
Parasites
E. coli O157
Enteroaggregative E. coli (EAEC)
Enteropathogenic E. coli (EPEC)
Enterotoxigenic E. coli (ETEC) lt/st
Shiga-like toxin-producing E. coli (STEC) stx1/stx2
Shigella/Enteroinvasive E. coli (EIEC)
Cryptosporidium
Cyclospora cayetanesis
Entamoeba histolytica
Giardia duodenalis
(aka lamblia & intestinalis)

*Currently, validated FDA-cleared probes exist only for pathogenic species. The use of probes in diagnostic assays that have not been validated or cleared by the FDA may decrease the accuracy of results.
 
Patient populations that may especially benefit from the comprehensive testing offered by the GI Pathogen Profile include:
  

  • Chronic or acute diarrhea
  • Bloody stool
  • Travelers diarrhea
  • Abdominal Pain
  • Fever & vomiting
  • Immuno-compromised patients
  • Geriatric Patients
  • Chronic disease patients (heart disease, aortic grafts, diabetes, chronic renal disease)
  • Observed cluster or suspected outbreak of diarrheal illness
Not all pathogenic microbes require antimicrobial treatment and such agents have no effect on viral infections. Certain pathogenic bacterial and parasitic infections call for rehydration and supportive therapies while others require antimicrobial treatment. Knowing the difference reduces the unnecessary use of antibiotics that may disrupt the microbiome, increase bacteria resistance, and the risk of complications and side effects associated with inappropriate use of antimicrobial agents. The test facilitates therapeutic efficacy.
 
Virus Detection
 
Viral infections are the predominant cause of acute diarrheal illness and are the least commonly tested. In fact, Norovirus is the primary GI infection occurring in the United States today. Practitioners have long awaited reliable molecular detection of GI viruses. The GI Pathogen Profile now makes this possible and may substantially improve patient outcomes and clinical success.
 
Consider a Comprehensive Stool Analysis
 
While the GI Pathogen Profile offers a targeted analysis for 22 known pathogenic microbes that are associated with gastrointestinal illness, co-infection of multiple organisms can occur. Additional stool testing may be valuable to further investigate organisms not included in the test that may play a role in the cause of symptoms and/or disease. Practitioners can look to the Comprehensive Stool Analysis w/ Parasitology profile from Doctor's Data for the identification and susceptibility of other bacteria, yeast, and parasites that may be contributing factors in such cases.
 
If your patient suffers from diarrheal illness, fast and accurate results are crucial. Consider the GI Pathogen Profile, multiplex PCR from Doctor's Data to aid in the rapid and precise identification of known pathogens that can cause serious patient morbidity.
