An epidemiological survey was carried out to investigate the distribution of the VP7 and VP4 specificities of lapine rotaviruses (LRVs) in rabbitries from different geographical regions of Italy. Almost all the strains were characterized as P[22],G3, confirming the presence of the newly-recognized rotavirus P[22] VP4 allele in Italian rabbits. Only one P[14],G3 LRV strain was identified and two samples contained a mixed (P[14] + [22],G3) rotavirus infection. All the LRV strains analyzed exhibited a genogroup I VP6 specificity and a long dsRNA electropherotype. However, one of the P[14],G3 strains possessed a super-short pattern. Altogether, these data highlight the epidemiological relevance of the P[22] LRVs in Italian rabbitries.

Abstract
An epidemiological survey was carried out to investigate the distribution of the VP7 and VP4 specificities of lapine rotaviruses (LRVs) in rabbitries from different geographical regions of Italy. Almost all the strains were characterized as P[22],G3, confirming the presence of the newly-recognized rotavirus P[22] VP4 allele in Italian rabbits. Only one P[14],G3 LRV strain was identified and two samples contained a mixed (P[14] + [22],G3) rotavirus infection. All the LRV strains analyzed exhibited a genogroup I VP6 specificity and a long dsRNA electropherotype. However, one of the P[14],G3 strains possessed a super-short pattern. Altogether, these data highlight the epidemiological relevance of the P[22] LRVs in Italian rabbitries.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
