A cross sectional study was designed to estimate the prevalence of summer eczema (a chronic, recurrent seasonal dermatitis) in exported Icelandic horses and the influence of environmental and genetic factors on the development of the disease. Among 330 horses, which had been exported to Germany, Denmark and Sweden, 114 (34.5%) were found to have clinical signs of summer eczema. The prevalence was highest 2 years after export and the exposure to the biting midges Culicoides spp., was found to be the main risk factor for developing the disease. Genetic influence on the sensitivity for the disease was not established. It was concluded that exported Icelandic horses are predisposed for summer dermatitis and the fact that they are not introduced to the antigens of the biting midges early in live, due to it's absence in Iceland, is likely to explain the high prevalence of the disease after export.
一项横断面研究旨在评估出口到国外的冰岛马夏季湿疹(一种慢性复发性季节性皮炎)的患病率,以及环境和遗传因素对该疾病发展的影响。在出口到德国、丹麦和瑞典的330匹马中,有114匹(34.5%)出现了夏季湿疹的临床症状。患病率在出口后2年最高,发现接触库蠓属叮咬蠓是患该病的主要风险因素。未确定该疾病敏感性的遗传影响。得出的结论是,出口的冰岛马易患夏季皮炎,由于冰岛没有库蠓,它们在生命早期没有接触到叮咬蠓的抗原,这可能解释了出口后该病的高患病率。
