Abstract

We analyzed ostriches from an equipped farm located in the Brazilian southeast region for the presence of Salmonella spp. This bacterium was investigated in 80 samples of ostrich droppings, 90 eggs, 30 samples of feed and 30 samples of droppings from rodents. Additionally, at slaughter-house this bacterium was investigated in droppings, caecal content, spleen, liver and carcasses from 90 slaughtered ostriches from the studied farm. Also, blood serum of those animals were harvested and submitted to serum plate agglutination using commercial Salmonella Pullorum antigen. No Salmonella spp. was detected in any eggs, caecal content, liver, spleen, carcass and droppings from ostriches and rodents. However, Salmonella Javiana and Salmonella enterica subsp. enterica 4, 12: i:- were isolated from some samples of feed. The serologic test was negative for all samples. Good sanitary farming management and the application of HACCP principles and GMP during the slaughtering process could explain the absence of Salmonella spp. in the tested samples.

摘要

我们对来自巴西东南部一个设施完备农场的鸵鸟进行了沙门氏菌属检测。对80份鸵鸟粪便样本、90枚鸵鸟蛋、30份饲料样本以及30份啮齿动物粪便样本进行了该细菌的调查。此外，在屠宰场，对来自该研究农场的90只屠宰鸵鸟的粪便、盲肠内容物、脾脏、肝脏和胴体进行了该细菌的调查。同时，采集了这些动物的血清，使用商用鸡白痢沙门氏菌抗原进行血清平板凝集试验。在鸵鸟和啮齿动物的任何蛋、盲肠内容物、肝脏、脾脏、胴体和粪便中均未检测到沙门氏菌属。然而，从一些饲料样本中分离出了爪哇那沙门氏菌和肠炎沙门氏菌亚种肠炎血清型4,12:i: - 。所有样本的血清学检测均为阴性。良好的卫生养殖管理以及在屠宰过程中应用危害分析与关键控制点（HACCP）原则和良好生产规范（GMP）可以解释检测样本中未出现沙门氏菌属的原因。
