Shedding of zoonotic pathogens and analysis of stomach contents in great cormorants [Phalacrocorax carbo sinensis) from Switzerland between 2007 and 2012

摘要

208 healthy great cormorants (Phalacrocorax carbo sinensis) shot during 5 consecutive hunting seasons from 2007/2008 until 2011/2012 were tested for Newcastle disease virus (APMV-1), avian influenza virus (AIV), Chlamydiae, and Salmonella spp. In addition, stomach contents were gross macroscopically examined. None of the birds was positive for APMV1, AIV or Chlamydiae. Twice Salmonella enterica subsp. enterica serovar Typhimurium and once a rough mutant of Salmonella Typhimurium were found. Stomach worms were found in 199 cormorants and 12 identifiable fish species in 45 stomaches.
