[Salmonella gallinarum biovar gallinarum as the cause of a highly acute septicemic disease in adult laying hens kept in battery cages].
Early in the summer of 1988 two flocks each of them consisted of about 7500 brown laying hens of a heavy hybrid line were affected by fowl typhoid. The birds have been bought at the age of 20 weeks and housed in two buildings placed close together in one farm. The disease started in flock I at the age of 26 weeks and in flock II at the age of 36 weeks. In repeated trials amoxicillin was effective in the treatment of fowl typhoid when given in the drinking water for ad libitum consumption over a 4-7 days period; however relapse occurred 3-4 days after withdrawal of the drug. All the hens were slaughtered 5 days after termination of the last therapy. In spite of the treatment 18.3% of the hens in flock I and 14.3% of those in flock II died within the observation period of 47 days and 22 days respectively. Egg production was not affected. The source of the fowl typhoid producing organisms could be not elucidated.
