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.
一匹24小时大的哈克尼小马驹出现虚弱、精神沉郁和吸吮反射差的症状，双肺听诊有粗糙的呼吸音；一匹48小时大、正常出生且吸吮有力的阿拉伯马驹出现腹泻，随后变得精神沉郁、虚弱和厌食。两匹幼驹血清IgG浓度均大于800mg/dl，但均有严重的中性粒细胞减少伴核左移，且二者血培养均分离出猪放线杆菌。分离出的猪放线杆菌具有不同的抗菌药敏模式，对于阿拉伯马驹，分离株对常用的广谱抗菌药物耐药。
