Enterococcus cecorum was isolated from the lesions and identified by(More)
Transcription of the proto-oncogene c-fos is stimulated by 17 beta-estradiol in estrogen responsive human and rat cells. To understand the molecular mechanisms of estrogen regulation of c-fos gene transcription, the human c-fos gene promoter, with 2.25 Kb of 5'-flanking DNA, was cloned upstream of the bacterial CAT gene and tested for estrogen regulation by(More)

Increased mortality was reported in two flocks of Muscovy ducklings from two consecutive hatches originating from the same breeder flock. Coughing, dyspnea, and gasping were observed in some ducklings between 6 and 11 days of age. Opaque white plugs of exudate were seen in the tracheas with some ducklings having multiple tracheal plugs. Tracheal and(More)
