Canine adenovirus type 1 (CAdV-1) and canine adenovirus type 2 (CAdV-2) cause infectious canine hepatitis (ICH) and infectious tracheobronchitis (ITB) in dogs, respectively. Cases of ICH have been documented in recent years and recent surveys have demonstrated a wide percentage of asymptomatic CAdV-1 infection in the canine population. Since both CAdV types are detectable in the same biological matrices, and viral coinfection with CAdV-1 and CAdV-2 are reported with high frequency, it is urgent to have available a rapid, highly sensitive and specific assay for the diagnosis of CAdV infection and distinction between CAdV-1 and CAdV-2. In order to detect canine adenovirus in biological samples and to rapidly distinguish the two viral types, a SYBR Green real-time PCR assay was optimized to discriminate CAdV-1 and CAdV-2 via a melting curve analysis. The developed assay showed high sensitivity and reproducibility and was highly efficient and specific in discriminating the two CAdV types. This reliable and rapid technique may represent a simple, useful and economic option for simultaneous CAdV types detection, which would be feasible and attractive for all diagnostic laboratories, both for clinical purposes and for epidemiological investigations.

Abstract
Canine adenovirus type 1 (CAdV-1) and canine adenovirus type 2 (CAdV-2) cause infectious canine hepatitis (ICH) and infectious tracheobronchitis (ITB) in dogs, respectively. Cases of ICH have been documented in recent years and recent surveys have demonstrated a wide percentage of asymptomatic CAdV-1 infection in the canine population. Since both CAdV types are detectable in the same biological matrices, and viral coinfection with CAdV-1 and CAdV-2 are reported with high frequency, it is urgent to have available a rapid, highly sensitive and specific assay for the diagnosis of CAdV infection and distinction between CAdV-1 and CAdV-2. In order to detect canine adenovirus in biological samples and to rapidly distinguish the two viral types, a SYBR Green real-time PCR assay was optimized to discriminate CAdV-1 and CAdV-2 via a melting curve analysis. The developed assay showed high sensitivity and reproducibility and was highly efficient and specific in discriminating the two CAdV types. This reliable and rapid technique may represent a simple, useful and economic option for simultaneous CAdV types detection, which would be feasible and attractive for all diagnostic laboratories, both for clinical purposes and for epidemiological investigations.File | Dimensione | Formato | |
