<abstract xmlns="http://www.w3.org/1999/xhtml"><p> The objective of this study was to show if porcine kobuvirus 1 (PKV-1) participates in the development of diarrhoea in piglets. The experiments were focused on comparing the occurrence of PKV-1 with the occurrence of rotavirus A (RVA) infection in suckling pigs on Slovak pig farms. A total of 91 rectal swabs of piglets (age &lt; 28 days) were collected from 8 pig farms. RT-PCR was employed to detect PKV-1 through amplification of the 495 bp fragment of the 3D gene using primers KoVF/ KoVR, and RVA was detected through amplification of the 309 bp fragment of the VP6 gene using primers rot3 and rot5. As expected, the detection of RVA in diarrhoeic piglets was 56.8 % (P &lt; 0.01), while only 14.8 % in healthy animals. These results confirm that RVA is one of the main causes of diarrhoea in young piglets. Comparatively, PKV-1 was detected in approximately equal numbers in the same group of both healthy and diarrhoeic pigs, with 74.1 % in healthy animals and 81.1 % in diarrhoeic animals, which was not statistically significant (P &lt; 0.05). The level of co-infection of both viruses was 11.1 % in healthy animals. A portion of 48.6 % (P &lt; 0.01) of diarrhoeic animals were found with RVA and PKV-1 coinfections. The results of this study indicate that while RVA is an enteric virus, PKV-1 cannot confidently be confirmed as an enteric pathogen. </p></abstract>
