旋毛虫病是一种人畜共患疾病,这在一些南美国家代表了一个重大的公共卫生问题,比如阿根廷和智利。它的影响主要是由于缺乏对野味动物肉的适当控制措施,以及非法屠宰场的存在和肉类产品贸易,而没有进行这种寄生虫的测试。在阿根廷,旋毛虫病是一种地方病。目前,旋毛虫,巴交旋毛虫,假旋毛虫,在阿根廷的动物中检测到了特里科氏菌。直到现在,仅在阿根廷的美洲狮(Pumaconcolor)中发现了T.patagoniensis,但可用的信息有限。本研究旨在确定易感性,感染T.patagoniensis的野猪中肌肉幼虫的血清学反应和分布,螺旋T.和假螺旋T.对于每种旋毛虫,用20,000个肌肉幼虫接种了5只野猪。除了两个在实验中死亡的标本,在感染后19周(pi)对动物实施安乐死。在整个研究中收集血样以确定抗体动力学。此外,从每个样本中采集9个肌肉样本,并进行分析以确定幼虫的分布。此外,使用四个肌肉样本来获得肌肉汁。在分析的肌肉样本中,感染了巴塔哥尼氏菌的野猪几乎没有幼虫,而感染了T.spialis和假螺旋T.pseudospialis的动物在所有分析的样本中都具有很高的幼虫负荷。在整个实验中,光密度(OD)值保持在临界值之上。这是首次描述野猪中T.patagoniensis生物学方面的研究。
Trichinellosis is a zoonotic disease, which represents a significant public health concern in some South American countries, such as Argentina and Chile. Its impact is essentially due to absence of adequate control measures on meat from game animals, as well as the presence of illegal slaughterhouses and the trade of meat products without being tested for this parasite. In Argentina, trichinellosis is an endemic disease. At present,
Trichinella spiralis,
Trichinella patagoniensis,
Trichinella pseudospiralis, and
Trichinella britovi have been detected in animals from Argentina. Until now, T. patagoniensis had only been found in mountain cougars (Puma concolor) in Argentina but there is limited information available. The present
study intends to determine susceptibility, serological response and distribution of muscle larvae in wild boars infected with T. patagoniensis, T. spiralis and T. pseudospiralis. For each of the
Trichinella species five wild boars were inoculated with 20,000 muscle larvae. Except for two specimens which died during the experiment, the animals were euthanized 19 weeks post infection (pi). Blood samples were collected throughout the
study in order to determine the antibody kinetics. Also, nine muscle samples from each specimen were taken and analysed for determination of larval distribution. Additionally, four muscle samples were used to obtain muscle juices. Wild boars infected with T. patagoniensis showed little to no larvae in the muscle samples analysed while animals infected with T. spiralis and T. pseudospiralis had a significantly high larval load in all the samples analysed. Optical density (OD) values remained above the cut-off value throughout the experiment. This is the first
study to characterize the biological aspects of T. patagoniensis in wild boars.
