Discovery and molecular characterization of a group A rotavirus strain detected in an Argentinean vicuña (Vicugna vicugna)

Molecular characterization of rotavirus isolated from alpaca ( Vicugna pacos ) crias with diarrhea in the Andean Region of Cusco, Peru

“…There is also evidence of antibodies to rotavirus (Rivera et al, 1987), or rotaviral antigen in crias with diarrhea in Peru (Morales et al, 2007, Lopez et al, 2011 in the Andes of Peru. Recent studies confirm rotaviral infection in guanaco crias by seroconversión and excretion of virus in feces (Marcoppido et al, 2011), and in vicuña by ELISA and molecular methods (Badaracco et al, 2013). These data indicate marked differences in frequency and distribution of enteric viruses in SACs in different geographical locations.…”

“…Thus, additional comparative genetic analysis of all segments would be indicated to establish linkages and evolutionary relationships with rotaviruses from other species dwelling in the same ecologic niche including humans as recently reported with group A giraffe and vicugna rotaviruses (O'shea et al, 2014;Badaracco et al, 2013). The full or partial genome sequence analysis reported in rotaviruses recovered from these species, suggests that interspecies circulation of viruses within a particular genotype constellation is a likely transmission event (O'shea et al, 2014;Badaracco et al, 2013). Further extensive sequencing and phylogenetic analysis would be required to verify whether rotaviruses recovered from other SACs or any other artiodactyls or humans within the same area of our study share such genotype constellations with the alpaca rotavirus isolates.…”

“…Thus, there is serologic and immunochemical evidence of exposure to bovine respiratory, enteric and systemic viruses (Rivera et al, 1987;Rosadio et al, 1993;Puntel, 1997;Puntel et al, 1999;Leoni et al, 2001;Victorio et al, 2004;Cabello et al, 2006;Marcoppido et al, 2010;Rosadio et al, 2011). Enteric disease, caused by protozoa, enteric bacteria and enteric viruses, remains a leading cause of morbidity and mortality of SAC crias (Parreño et al, 2004;Constantini et al, 2001;Cebra et al, 2003;Palacios et al, 2005;Whitehead and Anderson 2006;Morales et al, 2007;Starkey et al, 2007;Twomey et al, 2012;Lopez et al, 2011;Marcoppido et al, 2011;Badaracco et al, 2013). The negative effects of enteric disease in alpaca production are significant and indicate a need for further investigation to establish more precisely roles and impact of enteric pathogens in morbidity and mortality associated with diarrhea.…”

Isolation and characterization of a novel type of rotavirus species A in sugar gliders (Petaurus breviceps)

“…To date, RVA has been classified into 27 G, 37 P, 17 I, 9 R, 9 C, 8 M, 18 A, 10 N, 12 T, 16 E and 11 H genotypes (relating to VP7, VP4, VP6, VP1, VP2, VP3, NSP1, NSP2, NSP3, NSP4 and NSP5 genes, respectively) (Badaracco et al, 2013;Guo et al, 2012;Jere et al, 2014;Matthijnssens et al, 2011a;Trojnar et al, 2013).…”

Identification of two novel Rotavirus A genotypes, G35 and P[50], from Peruvian alpaca faeces

“…Few South American camelid (SAC) RVA strains have been characterized, but those that have showed great genotype diversity. The vicuña strain RVA/vicuña-wt/ARG/C75/2010/G8P[14] (Badaracco et al, 2013) and the guanaco strains RVA/Guanaco-wt/ARG/Chubut/ 1999/G8P [14] and RVA/Guanaco-wt/ARG/RíoNegro/1998/G8P[1] possess a bovine-like genome constellation, G8-P[1/14]-I2 . The guanaco strains also possess E12 and H3 NSP4 and NSP5 genotypes, respectively.…”
