Plain-English summary
Two foals, a 24-hour-old Hackney filly and a 48-hour-old Arabian colt, showed signs of serious illness. The filly was weak, very tired, and had trouble sucking, while the colt developed loose stools and stopped eating, becoming weak and depressed. Blood tests revealed that both foals had low white blood cell counts and tested positive for a bacteria called Actinobacillus suis. The bacteria from each foal responded differently to antibiotics, and the Arabian colt's bacteria were resistant to many common treatments. Unfortunately, the outcome of the treatment is not specified in the abstract.
Abstract
A 24-hour-old Hackney ony filly developed signs of weakness, depression and a poor suck reflex, with harsh lung sounds over both fields, and a 48-hour-old Arabian colt from a normal birth which had sucked vigorously developed loose stools and became depressed, weak and anorectic. Both foals had serum IgG concentrations greater than 800 mg/dl, but each had a severe neutropenia with a left shift, and blood cultures from both of them yielded Actinobacillus suis. The A suis isolates had different antimicrobial susceptibility patterns and, in the case of the Arabian, the isolate was resistant to commonly used broad spectrum antimicrobial agents.
