Epidemiology of Rotavirus C in Czech pig farms

Popis výsledku v původním jazyce

Poster at „Symposium dsRNA Virus“ held in Porto, Portugal, 03.11. – 07. 11. 2025. Rotavirus C (RVC) was first described as a causative agent of diarrhoea in piglets and also detected in humans, cows, ferrets and dogs. Several studies have shown an association between porcine RVCs and gastroenteritis in pigs of different age categories. The genetic diversity of RVCs described so far is much broader in pigs than in other hosts. Currently, with the development of modern molecular biological diagnostic methods, RVC is being detected more frequently, and it was earlier reported as the main single cause of neonatal diarrhea in piglets. During the ongoing study which began in June 2023, a total of 160 samples of domestic pig (Sus scrofa f. domestica) faeces of various age categories were examined. Out of this number, 115 were positive for RVA (71.9%), RVB was detected in 86 samples (53.8%) and 70 samples were positive for RVC (43.8%). Only 18.8% of examined samples were negative for all three rotavirus groups. More than half of the samples (56.9%) contained two or three rotavirus groups in different combinations. As for the RVs presence in relation to the age of pigs, most of the single RV-group infection occurred in suckling piglets, while mixed infections were more common after weaning. Continuing genotyping classified the obtained RVC-positive samples into following VP7-genotypes – G1, G6, G9, G10. These were in combination with P[1], P[5], P[6], and P[9] VP4-genotypes. The only I-genotype detected so far is I13.
