Pathogenicity of Enterococcus hirae for chicken embryos and betamethasone-treated chicks.
An isolate Enterococcus hirae was used to determine its pathogenicity for chicken embryos and for chicks treated with betamethasone. E hirae was inoculated intravenously into four-day-old chicks which had been treated for three consecutive days with betamethasone, and chick embryos were inoculated into the allantoic cavity with 10(2) and 10(3) bacteria. E hirae was not pathogenic for the chicks or for the embryos.
