Organisms associated with diarrhoea in 153 calves included Escherichia coli and Enterobacter (66%), Salmonella-Shigella-Citrobacter (12%), Proteus-Providencia (15%), and some others (7%). 90% of the predominant organisms were sensitive to a combination of trimethoprim plus sulfadiazine, followed by chloramphenicol (89%) and nifuraldezone (86%). Trimethoprim alone was effective against 60% of isolates and sulfadiazine alone was effective against 10.5%.
