We report on a coinfection of Mycobacterium avium subsp. avium and Salmonella enterica serotype Typhimurium var. Copenhagen phage type DT2 in pigeons from one flock, from which squabs were occasionally consumed by humans. Triplex quantitative real-time PCR and culture methods were used for M. a. avium detection in livers and culture method was used for the detection of Salmonella sp. in samples of liver and caecum of 33 examined birds. M. a. avium was detected in a total of 31 (93.9%) and Salmonella Typhimurium in a total of 11 (33.3%) pigeons. Coinfection with both pathogens was found in 10 (30.3%), infection with Salmonella Typhimurium alone in 1 (3.0%), and infection with M. a. avium alone in 21 (63.7%) pigeons. Neither pathogen was detected in one pigeon. There was no difference in clinical symptoms exhibited by pigeons infected by M. a. avium and/or Salmonella Typhimurium. All Salmonella Typhimurium isolates were sensitive to all 15 antimicrobials tested. According to these results we emphasize good heat treatment of consumed squabs.
我们报告了一例鸽群中发生的鸟分枝杆菌亚种和肠炎沙门氏菌血清型都柏林噬菌体型 DT2 共感染，这些鸽子偶尔会被人类食用。采用三重实时定量 PCR 和培养方法检测肝脏中的鸟分枝杆菌，采用培养方法检测肝脏和盲肠样本中的沙门氏菌。在 33 只受检鸟中，共检测到 31 只（93.9%）鸽有鸟分枝杆菌，11 只（33.3%）鸽有肠炎沙门氏菌。10 只（30.3%）鸽同时感染了这两种病原体，1 只（3.0%）鸽单独感染了肠炎沙门氏菌，21 只（63.7%）鸽单独感染了鸟分枝杆菌。有一只鸽子未检测到病原体。感染鸟分枝杆菌和/或肠炎沙门氏菌的鸽子在临床症状上没有差异。所有肠炎沙门氏菌分离株对 15 种测试的抗菌药物均敏感。根据这些结果，我们强调了食用乳鸽时要进行充分的热处理。
