| isolation of avian influenza viruses from two different transhemispheric migratory shorebird species in australia. | shorebirds on their southerly migration from siberia to australia, may pass through asian regions currently experiencing outbreaks of highly pathogenic h5n1 influenza. to test for the presence of avian influenza viruses in migratory shorebirds arriving in australia during spring 2004, 173 cloacal swabs were collected from six species. ten swabs were positive for influenza a, with h4n8 viruses detected in five red-necked stints and h11n9 viruses detected in five sharp-tailed sandpipers. no h5n1 v ... | 2006 | 16732420 |
| surveillance of charadriiformes in northern australia shows species variations in exposure to avian influenza virus and suggests negligible virus prevalence. | the virologic surveillance of 4248 charadriiformes since 1992 primarily from coastal northwest australia did not detect any evidence of avian influenza virus (aiv) excretion (test prevalence = 0%; 95% confidence interval [ci]: 0%-0.09%). past exposure to aiv was evident from serologic testing using nucleoprotein (np) competitive-elisa (c-elisa) with an overall seroprevalence of 8.8% (95% ci: 8%-9.7%). the c-elisa seroprevalence of family scolopacidae and genus numenius was significantly higher w ... | 2014 | 25055621 |
| orientation and autumn migration routes of juvenile sharp-tailed sandpipers at a staging site in alaska. | arctic waders are well known for their impressive long-distance migrations between their high northerly breeding grounds and wintering areas in the southern hemisphere. performing such long migrations requires precise orientation mechanisms. we conducted orientation cage experiments with juvenile sharp-tailed sandpipers (calidris acuminata) to investigate what cues they rely on when departing from alaska on their long autumn migration flights across the pacific ocean to australasia, and which po ... | 2010 | 20472769 |
