Abstract

The Feline Enteric Virus Detection Assay is intended as an in vitro veterinary reagent set, based on Reverse Transcription quantitative PCR (RT-qPCR), for the detection of feline coronavirus (FCoV)/feline infectious peritonitis (FIP), feline panleukopenia virus (FPV; feline parvovirus), feline rotavirus A (FRV) and SARS-CoV-2 in rectal swabs and fecal samples.

Steps

Reaction Set Up

Thaw all reagents on ice.

Centrifuge all reagents on a benchtop centrifuge to ensure no liquid is in cap and keep on ice

Note

The Feline Enteric Virus Detection Assay does not include an internal control, but positive controls are provided. A positive and a negative control should be run simultaneously with each sample setup.

Setup the Master Mix according to the following table 1:

PROGRAMMING THE THERMOCYCLER

Select the following fluorescence channels: ABY^TM, FAM^TM, JUN^TM and VIC^TM.

Note

ROX^TM should be used as a passive reference dye.

The standard mode should be selected, following the table below:

Table 2. Thermo profile

RESULTS INTERPRETATION

Before analysis of results, the threshold value of each fluorescent dye must be manually set in the region of exponential amplification, typically 0.1 × ΔRn value at the plateau phase.

Each assay is considered valid if the following criteria are met:

Table 3. Positive control validation criteria

The results are qualitative (Positive or Negative). A specimen is considered positive if the Ct value obtained is below the following Ct cut-off values:
