Serological Monitoring of Avian Influenza in Migratory Birds of Iran
Although migratory waterfowl is well known to be a major reservoir for avian influenza virus (AIV), there are only few recently published reports about the seroprevalence of AIV in this group of birds. To investigate the AIV antibody status in migratory waterfowl of Iran, we collected 217 serum samples from 25 different species of waterfowl during 2003 and 2004. These serum samples were teste...
متن کاملBehavioral barriers to non-migratory movements of birds
Although effects of physical barriers to animal movement are well established, the behavioral inhibition of individuals moving across habitat gaps, ecotones, and interpatch (matrix) habitat has received little attention.

متن کاملMigratory Birds Make
sions about site settlement on both breeding and nonbreeding grounds. Each year a fraction of surviving individuals return to sites occupied in previous years. The accumulation of capture histories, and the widespread distribution of capture–recapture software to analyze such data (Lebreton et al. 1992) have lead to a proliferation of estimates of apparent annual survival rates for migratory bi...
متن کاملWorldwide spread of NDM-1: are migratory birds culprits?
Key words: NDM-1; migratory birds; drug resistance. Multi-drug resistance has become a major threat to community acquired and nosocomial infections, worldwide [1]. Carbapenems are used as last resort drugs because of the increasing resistance against beta-lactam group antibiotics. The resistance against the carbapenem antibiotic class has also emerged worldwide for at least a decade and became ...
