PRESENCE OF AVIAN INFLUENZA-VIRUS (AIV) SUBTYPES H5N2 AND H7N1 IN EMUS (DROMAIUS-NOVAEHOLLANDIAE) AND RHEAS (RHEA-AMERICANA) - VIRUS ISOLATION AND SEROLOGIC FINDINGS
B. Panigrahy et al., PRESENCE OF AVIAN INFLUENZA-VIRUS (AIV) SUBTYPES H5N2 AND H7N1 IN EMUS (DROMAIUS-NOVAEHOLLANDIAE) AND RHEAS (RHEA-AMERICANA) - VIRUS ISOLATION AND SEROLOGIC FINDINGS, Avian diseases, 39(1), 1995, pp. 64-67
Avian influenza virus (AIV) subtypes H5N2 and H7N1 were isolated from
emus (Dvomaius novaehollandiae) and rheas (Rhea americana) in Texas an
d North Carolina. All the rheas and emus had a history of respiratory
disease except one emu, which was clinically normal. The isolates were
not pathogenic for chickens and turkeys under the conditions of the e
xperiment. Humoral antibodies to all known hemagglutinin (H) subtypes
except H10, H13, and H14 and to all nine neuraminidase (N) subtypes we
re found in emus and rheas in 11 states. Therefore, emus and rheas are
susceptible to infection with several AIV subtypes.
