Isolation of Salmonella victoria from a cow

At the end of January 1972, specimens were submitted to this laboratory from a cow in the Geraldine district, which was one of three that died suddenly after transfer to a new, clover-dominant pasture. All apparently died from the same cause and post-mortem examination revealed reddened external mucosae, froth at nostrils, and gas distension of the carcasses. In addition, there was mild reddening of abomasal mucosa, severe reddening of intestinal mucosa, and congestion of the liver and lungs. Enterotoxaemia, salmonellosis, blood poisoning or irritant poisoning was suspected.
