Abstract

To investigate possible reasons for recent declines in Red Knot (Calidris canutus rufa) populations we surveyed for selected pathogens in Red Knots captured in San Antonio Bay, Argentina, on their northward migration during the period 2006-2011. Blood, cloacal swabs and faeces were analysed for bacteria [Salmonella sp., Shigella sp., enteropathogenic Escherichia coli (N = 42) and other coliforms (N = 35)], viral agents [responsible for avian influenza (N = 239), St. Louis encephalitis (N = 51) and Newcastle disease (N = 239)] and avian malaria parasites [Plasmodium sp. and Haemoproteus sp. (N = 284)]. All 698 samples taken from 303 individuals were negative, providing no evidence that Red Knots sampled at this stopover site were infected with these pathogens at the time of sampling. © 2014 Dt.
