INFLUENCE OF FEEDING PATTERNS ON THE ARTIFICIAL INFECTION OF LAYING HENS WITH SALMONELLA-ENTERITIDIS PHAGE TYPE-4

Salmonella enteritidis phage type 4 was recovered significantly more frequently from the crops of birds which had been denied food for 24 hours than from birds allowed food ad libitum. There was, however, no difference in its isolation rate from tissues. Within one hour of infection, S enteritidis could be recovered from a variety of tissues, including the oviduct, of a small proportion of the infected birds.
