Statistics of detected parasites
Here is the compilation of the results of parasitology profiles and qPCR parasites/digestive profiles produced at Biovet in cats and dogs since 2017.
The parasitology analyses performed by the zinc sulphate double centrifugal flotation technique.
The qPCR parasites profiles include qPCR analysis of Giardia intestinalis, Cryptosporidium spp, Toxoplasma gondii and Tritrichomonas fetus for cats and Giardia intestinalis and Cryptosporidium spp for dogs.
The qPCR digestive profile allows the detection of major viruses, parasites or bacteria involved in the digestive system of pets. For the feline digestive profile 11 agents are analyzed: feline panleucopennia virus, feline coronavirus, rotavirus A, Campylobacter jejuni, Campylobacter coli, Salmonella spp, Clostridium perfringens, Cryptosporidium spp, Giardia intestinalis, Tritrichomonas fetus and Toxoplasma gondii. For the canine digestive profile, 10 agents are analyzed including canine parvovirus, canine coronavirus, canine circovirus, distemper, Campylobacter jejuni, Campylobacter coli, Salmonella spp, Clostridium perfringens, Cryptosporidium spp and Giardia intestinalis.
The table reports the percentage of positive samples revealed by parasitology, the qPCR of digestive profiles and parasite qPCR and the combined results of these two analyses (parasitology and qPCR).
What to remember:
- Parasitology analyses can detect a wider range of intestinal parasites than PCR (see list of the various parasites identified in the Other Parasites section of the Table).
- Although parasitology analyses can detect several intestinal parasites with good sensitivity, the parasite detection rate is increased when parasitology is combined with a PCR analysis.
- PCR analyses allow better sensitivity for the detection of certain parasites compared to microscopy, including for Giardia, Tritrichomonas fetus and Toxoplasma; the last two parasites also have little perceptibility in microscopy. The detection of Cryptosporidium by PCR is at least as sensitive as parasitology for cats but more sensitive for dogs.
- The parasitology and qPCR profile detected at least one parasite in nearly one-third of the samples submitted for dogs and nearly a quarter of the samples submitted for cats.
