On a farm in Aichi Prefecture, a disease with diarrhea broke out among 300 pigs one to two months of age, and 30 pigs died in October, 1978. Autopsy of three pigs revealed accumulation of yellowish watery contents in the intestines and inflamed intestinal lymph nodes. Histological examination revealed activation of the reticuloendothelial cells of the liver, spleen and intestinal lymph nodes. Bacteriologically, large amounts of Salmonella sp.(1) serovar infantis (6, 7: r: 1, 5) were isolated from all the organs and feces of pigs showing diarrhea.
Susceptibility to drugs, such as CER, CL, GM, NA, OA and FZ, was demonstrated, as was resistance to PC-G, AB-PC, DSM, FM, CP, CTC, OTC, and SDM.
