At a dairy farm with 89 heads within a week after a pregnant cow suffered from diarrhea and had abortion, dairy cows became feverish, anorectic, and emaciated, suffering from diarrhea with remarkable decrease in milk yield. <I>Salmonella</I> Heidelberg (SH) was isolated from 4 diseased cases and 9 non-diseased adults, and S. Infantis (SI) was from 1 diseased and 5 non-diseased cases. The isolates were sensitive to many antibacterial agents, and the SH isolates from animals and environmental samples showed the same plasmid patterm, while the SI isolates had no plasmids. The organisms were isolated from many environmental samples but not from nursing cows and feed. Both organisms were not isolated from captured crows.
