Abstract
Feline parvovirus causes infectious diseases, and Chaphamaparvovirus is a novel type of feline parvovirus. The present study aims to establish a method that can be used in clinical rapid detection of feline Chaphamaparvovirus (FeChPV), for facilitate the timely and effective diagnosis and treatment of sick animals and shorten the diagnosis time of clinical diseases. The experimental samples in this study are from 20 cats undergoing physical examination in Hefei Xin’an Animal Hospital. An SYBR Green I-based qPCR assay was performed to detect FeChPV. A pair of specific primers was designed based on the VP1 gene to perform the assay. The detection assay showed high sensitivity with a detection limit of 1.07 × 101 copies/μL and high specificity for detection of only the target virus. The coefficients of Ct value variation were calculated to assess the reproducibility of the qPCR assay, and the inter- and intra-assay ranged from 0.21 to 0.67% and 0.10 to 0.56%, respectively. The result of clinical sample detection showed that the infection rate of FeChPV in 124 samples detected using qPCR assay was higher than that with conventional PCR. The established qPCR assay could be a low-cost, convenient, and reliable method to detect FeChPV in clinical practice.
