The faunas contain more than 30 species and are characterized by an abundance of small nassellarians with a constricted distal end. The faunas compare well with Tethyan faunas, and are...

متن کاملIncidence of Salmonella infection in healthy dogs in Gifu Prefecture, Japan.
A total of 1,013 feces samples and 8 mesenteric lymphonodus samples obtained from apparently healthy dogs were examined for the incidence of salmonella infection. One strain of S. typhimurium (ST) was isolated from feces of one dog, and S. enteritidis (SE) was isolated from the mesenteric lymphonodus of one dog. Sera obtained from 330 apparently healthy dogs were examined for Salmonella antibod...
