What does the Pathogenic Bacterial Isolates test measure?

Q: What is the reference range for Pathogenic Bacterial Isolates?

The standard reference range for Pathogenic Bacterial Isolates is No growth of Salmonella, Shigella, Campylobacter, Yersinia, pathogenic E. coli, Vibrio, or Aeromonas species; see laboratory-specific reporting criteria.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Pathogenic Bacterial Isolates (Culture) is a clinical biomarker used in infectious-disease assessment. The gastrointestinal tract harbours a complex microbial ecosystem in which commensal organisms outnumber pathogens many-fold. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Pathogenic Bacterial Isolates?

The gastrointestinal tract harbours a complex microbial ecosystem in which commensal organisms outnumber pathogens many-fold. Traditional stool culture employs selective and differential media to isolate known enteric bacterial pathogens — Salmonella, Shigella, Campylobacter, pathogenic Escherichia coli (including enterohaemorrhagic, enterotoxigenic, and enteroinvasive pathotypes), Yersinia enterocolitica, Vibrio, and Aeromonas species — that are not part of the normal flora. Recovery depends on organism load, transport time, and prior antimicrobial exposure.

Why is Pathogenic Bacterial Isolates measured?

Detection of a pathogenic isolate confirms bacterial gastroenteritis, informs antimicrobial choice, and enables public health reporting. Negative culture does not exclude bacterial infection if the organism is fastidious, the specimen was delayed, or antimicrobials were started before collection. Culture sensitivities guide therapy when resistance is suspected and help tailor treatment in severe or persistent disease.
