Abstract：
The diagnosis of enteric disorders in pigs is extremely challenging, at any age. Outbreaks of enteric disease in pigs are frequently multifactorial and multiple microorganisms can co-exist and interact. Furthermore, several pathogens, such as Clostridium perfrigens type A, Rotavirus and Lawsonia intracellularis, may be present in the gut in the absence of clinical signs. Thus, diagnosis must be based on a differential approach in order to develop a tailored control strategy, considering that treatment and control programs for enteric diseases are pathogen-specific. Correct sampling for laboratory analyses is fundamental for the diagnostic work-up of enteric disease in pigs. For example, histology is the diagnostic gold standard for several enteric disorders, and sampling must ensure the collection of representative and optimal intestinal samples. The aim of this paper is to focus on the diagnostic approach, from sampling to the aetiological diagnosis, of enteric disorders in pigs due to different pathogens during the different phases of production.
摘要：
猪肠道疾病的诊断极具挑战性,在任何年龄。猪肠道疾病的爆发通常是多因素的，并且多种微生物可以共存并相互作用。此外，几种病原体，如A型产气梭菌，细胞内轮状病毒和劳森菌，在没有临床症状的情况下可能存在于肠道中。因此，诊断必须基于差分方法，以便制定量身定制的控制策略，考虑到肠道疾病的治疗和控制方案是病原体特异性的。用于实验室分析的正确采样是诊断猪肠道疾病的基础。例如,组织学是几种肠道疾病的诊断金标准，采样必须确保收集有代表性和最佳的肠道样本。本文的目的是关注诊断方法，从取样到病因诊断，在生产的不同阶段，由于不同的病原体而导致的猪肠道疾病。
