Abstract

Las poblaciones de llamas de Argentina se concentran principalmente en la provincia de Jujuy; su explotación representa un importante recurso económico de las comunidades altoandinas. El objetivo de este trabajo fue evaluar la seroprevalencia de anticuerpos contra algunos agentes virales asociados a enfermedades de impacto productivo en rodeos de llamas de Jujuy. Se analizaron 349 sueros de llamas adultas de 6 departamentos de la puna jujeña ubicados por encima de los 3300 msnm. Se obtuvo una prevalencia del 100 % para rotavirus grupo A y del 70 % para el virus parainfluenza-3 bovino, mientras que no se detectaron reactores para herpesvirus bovino 1, virus de la diarrea viral bovina, influenza A humana (H1N1) e influenza equina (H3N8). Los resultados obtenidos confirman la amplia distribución de rotavirus y virus parainfluenza y la baja susceptibilidad a herpesvirus y pestivirus en las tropas de llamas de la puna jujeña.

Translated abstract

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.

Are human P[14] rotavirus strains the result of interspecies transmissions from sheep or other ungulates that belong to the mammalian order Artiodactyla?

Jelle Matthijnssens, Christiaan A Potgieter, Max Ciarlet … (2009)

A limited number of human G6P[14] rotavirus strains that cause gastroenteritis in humans have been isolated in Europe and Australia. The complete genome sequences were determined for five of these human strains--B10925-97 (isolated in Belgium in 1997), 111/05-27 (Italy, 2005), PA169 (Italy, 1987), MG6 (Australia, 1993), and Hun5 (Hungary, 1997)--and their genetic relatedness to animal rotavirus strains was evaluated by sequencing the complete genome of the sheep rotavirus OVR762 (G8P[14]; Spain, 2002), the guanaco (Lama guanicoe) rotavirus strains Arg/Chubut/99 and Arg/Río Negro/98 (G8P[14] and G8P[1], respectively; Argentina, 1999 and 1998), the sable antelope strain RC-18/08 (G6P[14]; South Africa, 2008), and the bovine rotavirus strain Arg/B383/98 (G15P[11]; Argentina, 1998). These analyses revealed an overall consensus genomic constellation (G6/G8)-P[14]-I2-(R2/R5)-C2-M2-(A3/A11)-N2-T6-(E2/E12)-H3, together with a few gene reassortments, and the phylogenetic analyses confirmed that the P[14] human strains evaluated in this study were closely related to rotavirus strains isolated from sheep, cattle, goats, guanacos, and antelopes and to rabbits (albeit to a lesser extent), suggesting that one (or more) of these animal species might be the source of the human G6P[14] strains. The main feature of the genotype and phylogenetic analyses was the close overall genomic relatedness between the five human G6P[14] rotavirus strains and the ovine and antelope rotavirus strains. Taken together, these data strongly suggest a common origin for the human P[14] strains and those of the even-toed ungulates belonging to the mammalian order Artiodactyla, with sheep probably playing a key role in the interspecies transmission responsible for the introduction of P[14] rotavirus strains into the human population.

Serologic survey of viral antibodies in the Peruvian alpaca (Lama pacos).

H Rivera, B R Madewell, E Ameghino (1987)

Sera from more than 100 alpacas (Lama pacos) from the Peruvian southern sierra were examined for antibodies to 8 viruses known to infect other domestic animals. On the basis of these serologic findings and previously published serologic or clinical data, it is now known that the alpaca can be infected with the following viruses: parainfluenza-3, bovine respiratory syncytial virus, bovine herpesvirus-1, bluetongue virus, border disease virus, influenza A virus, rotavirus, rabies virus, vesicular stomatitis virus, foot-and-mouth disease virus, and contagious ecthyma virus.

Antibodies to pathogenic livestock viruses in a wild vicuña (Vicugna vicugna) population in the Argentinean Andean altiplano.

Gisela Marcoppido, Bibiana Vilá, Viviana Parreño (2010)

Serum samples from 128 wild vicuñas (Vicugna vicugna) were tested for antibodies (Ab) to rotavirus (RV), bovine parainfluenza virus 3 (BPIV-3), bovine herpesvirus-1 (BHV-1), bovine viral diarrhea virus (BVDV-1), foot-and-mouth disease virus (FMDV), bluetongue virus (BTV), equine herpesvirus-1 (EHV-1), and influenza A virus equine (EIV). Samples were collected in Cieneguillas Province of Jujuy, in northern Argentina. Feces from 44 vicuñas were also collected to investigate RV shedding. Llamas (Lama glama) and domestic cattle (Bos taurus) from the area studied also were tested for antibodies to these viruses. Antibodies against RV (100%) and BPIV-3 (37%) were detected in the vicuñas sampled. No RV antigen was detected in any of the fecal samples tested. One vicuña was positive for Ab to BHV-1 (0.8%) and another for BVDV-1 (0.8%). The Ab prevalences detected in llamas were: 100% (16/16) for RV, 47% (8/17) for BPIV-3, 17.6% (3/17) for BHV-1, and 5.9% (1/17) for BVDV-1. However, domestic cattle had high antibody prevalences for RV and BPIV-3, 100% (13/13) and 73% (11/15), respectively, but were negative for Ab to BHV-1 and BVDV. No antibodies against FMDV, BTV, EHV-1, or EIV were detected in wild vicuñas or domestic species. Because no data of viral circulation on wild vicuñas are available, this report represents the first evidence of viral infection in wild vicuñas from the Argentinean Andean Puna.
