[Serological survey of antibodies against viral diseases of public health interest in llamas (Lama glama) from Jujuy province, Argentina].

Llama population from Argentina is mainly concentrated in the Andean Puna, Jujuy. Llamas represent an important economic resource for the Andean communities. The aim of this study was to investigate the prevalence of antibodies against viral antigens associated to viral diseases of economic impact (neonatal diarrhea, reproductive and respiratory syndromes). A total of 349 serum samples from adult llamas were analyzed. The obtained antibody prevalence was 100 % for Rotavirus A and 70 % for Bovine parainfluenza virus 3. In contrast, no reactors were detected to Bovine herpesvirus 1, Bovine viral diarrhea virus 1, Human influenza A virus (H1N1) and Equine influenza virus (H3N8). These results confirm the wide circulation of rotavirus and parainfluenza virus in Argentinean llamas and suggest that susceptibility to infection with bovine herpesvirus, pestivirus and influenza A viruses is low. This serologic survey provides novel information regarding the epidemiology of viral diseases affecting llamas from the Argentinean Andean Puna.
