Canine Stool Parasite Screen

18S Amplicon Sequencing for Canine Parasite Detection

The PathOID.ai Canine Stool Parasite Screen uses 18S ribosomal RNA amplicon sequencing to identify eukaryotic parasites and fungi present in your dog's gastrointestinal tract. Sequencing reads are classified against a curated reference database of nearly 500,000 18S rRNA sequences spanning 33 eukaryotic phyla, developed specifically for eukaryotic pathogen detection.

Why this matters for dog owners: Dogs are a significant reservoir host for numerous zoonotic parasites — organisms capable of transmitting from animals to humans through environmental contamination, direct contact, or ingestion. Many of these infections are subclinical in dogs, meaning your pet may show no symptoms while actively shedding infectious material. Conventional fecal float testing is limited in sensitivity and detects only a fraction of the eukaryotic organisms that may be present.

18S amplicon sequencing detects organism DNA directly, identifying parasites and fungi at the genetic level regardless of lifecycle stage, egg burden, or organism morphology.

Organisms targeted include: Giardia species, Cryptosporidium species, Blastocystis subtypes, hookworm (Ancylostomatidae), Toxocara canis, Trichuris vulpis (whipworm), Neospora caninum, tapeworms (Platyhelminthes), pathogenic fungi including Aspergillus and Candida species, and hundreds of additional eukaryotic organisms across 33 phyla.

Accepted Sample Type: Dog stool (home collection kit included)
