This 5-year retrospective study reports 54 patients with infection, caused by Streptococcus canis, a pyogenic Lancefield group G streptococcus initially isolated from various animal sources. During 1997-2002, Streptococcus canis accounted for 1% of all streptococci isolated. The clinical signs, outcome and bacteriological characteristics were reviewed. All except eight were symptomatic. Clinical manifestations were: soft tissue infection (n=35), bacteremia (n=5), urinary infection (n=3), bone infection (n=2) and pneumonia (n=1). The course was favorable in 52 cases while two died from sepsis. Cultures were often polymicrobial (n=42, 77.8%) apart from hemocultures. The isolates were sensitive to most antibiotics. Presence of the bacteria did not always signify infection owing to the possible occurrence of colonization. The frequency of S. canis infections is rare and likely underestimated owing to the fact that streptococci are sought only on the basis of the Lancefield classification. The search for S. canis is recommended whenever patients present with symptoms evocative of exposure to a potentially contaminated animal.
这项为期5年的回顾性研究报告了54例由犬链球菌引起感染的患者，犬链球菌是一种化脓性的兰斯菲尔德G组链球菌，最初从各种动物源中分离出来。在1997年至2002年期间，犬链球菌占所有分离出的链球菌的1%。对其临床症状、转归和细菌学特征进行了回顾。除8例无症状外，其余均有症状。临床表现为：软组织感染（n = 35）、菌血症（n = 5）、泌尿系统感染（n = 3）、骨感染（n = 2）和肺炎（n = 1）。52例病情转归良好，2例死于败血症。除血培养外，培养结果常为多种微生物混合感染（n = 42，77.8%）。分离菌株对大多数抗生素敏感。由于可能存在定植情况，细菌的存在并不总是意味着感染。犬链球菌感染的发生率很低，而且可能因仅根据兰斯菲尔德分类法来寻找链球菌而被低估。当患者出现提示接触过潜在污染动物的症状时，建议进行犬链球菌的检测。
