ABSTRACT
Eight dairy flocks, comprising a total of 323 indigenous Passirian goats from northern Italy, were examined to determine the seroprevalence and clinical incidence of small ruminant lentivirus (SRLV) infections and to identify the SRLV subtypes. The seroprevalence was 81.5% (55-95%). The clinical incidence was 2.5% (0-8.3%) and was apparently low due to the practice of culling clinically affected animals. Phylogenetic analysis of eight PCR fragments (one sample from each flock) revealed that all proviruses belonged to the SRLV subtype B1, which suggests a common source of infection. Subtype B1 being the only circulating SRLV, coupled with the fact that mixed herd systems are very rare in South Tyrol, gives hope that an eradication programme in goats can be successful even without including sheep as long as sheep are kept strictly and permanently isolated.
