(A) Gel image of PCR results with CAdV-1/2-specific primer sets. All 24 samples of the full assortment were negative for CAdV-1/2. M – 100 bp marker; (-) – negative control; (+) – CAdV-2 positive control showing a band at 1,031 bp. (B) Gel image of PCR results with CPV-specific primer sets. Fifteen out of sixteen faecal samples were positive for CPV. M – 100 bp marker; (-) – negative control; (+) – CPV positive control showing a band at 630 bp. (C) Gel image of PCR results with CDV-specific primer sets. Three out of six nasal swab samples were positive for CDV. M – marker; (-) – negative control. (D) Gel images of second-round nested PCR results with CHV-1-specific primer sets. Five out of twenty-three nasal swab samples were positive for CHV-1. M – marker; (-) – negative control; (+) – CHV-1 positive control showing a band at 170 bp

Phylogenetic tree based on the partial VP2 gene of canine parvovirustype 2 (CPV 2) constructed using the neighbour-joining method. Bootstrap analysis was performed with 1,000 repetitions. CHI – Chinese origin; NG – Nigerian origin; IND – Indian origin; EGY – Egyptian origin; KNY – origin in Konya province of Türkiye; KOR – South Korean origin; ECUA – Ecuadorian origin; ITA – Italian origin; AUS – Australian origin; GER – German origin; JAP – Japanese origin; SPA – Spanish origin; MUG – origin in Muğla province of Türkiye; DEN – origin in Denizli province of Türkiye; MAR – origin in Kahramanmaraş province of Türkiye; COL – Colombian origin; ARG – Argentinian origin; UY – Uruguayan origin; BG – Bangladeshi origin. Purple dots indicate isolates obtained in the present research. Numbers on tree branches are bootstrap support values
