Of 121 foals that died between one and 3 months of age, 68 had E. coli infection, 12 Klebsiella pneumoniae infection, 8 Salmonella infections, and 12 Streptococcus zooepidemicus and Corynebacterium equi. Acute E. coli infections were accompanied by lesions of the lungs and lymphoid organs, while subacute infections were associated with polyarthritis and polyserositis. Subacute E. coli infections were pathologically similar to K. pneumoniae infection. Of 8 foals with Salmonella infections, 5 were in the age range 6-12 weeks, with polyarthritis; Streptococcus zooepidemicus and C. equi infections also occurred mainly in older foals. Actinobacillus equuli, previously the most important agent, accounted for only 1.6% of infections.
