Trombiculids parasitize a wide variety of terrestrial vertebrates, including domestic animals, throughout the world. They are parasites only during their larval stages, causing several dermatological lesions on their hosts, such as acute dermatitis, erythema, excoriation, erosion, papules, crusts and alopecia on the ear margins, face, interdigital spaces and abdomen. Neotrombicula is one of the several genera in Trombiculidae family, which cause trombiculosis. The most common species implicated in clinical cases is Neotrombicula autumnalis. However, several reports have shown that Neotrombicula inopinata (Oudemans, 1909) can also play a role in trombiculosis. Here, we describe the first case of N. inopinata infestation in domestic cats from mainland Portugal. Since nucleic acids of Anaplasma phagocytophilum and Borrelia burgdorferi have been found in Neotrombicula autumnalis and Rickettsia spp. in Neotrombicula inopinata, a correct taxonomical identification is essential to understand the role of these mite species as possible vectors of pathogens.
恙螨寄生于世界各地的多种陆生脊椎动物，包括家畜。它们仅在幼虫阶段寄生，会在宿主身上引发多种皮肤病变，如急性皮炎、红斑、擦伤、糜烂、丘疹、结痂以及耳部边缘、面部、指间和腹部的脱毛。新恙螨属是恙螨科中能引起恙螨病的几个属之一。临床病例中最常见的物种是秋新恙螨。然而，有几份报告表明，意外新恙螨（奥氏，1909年）在恙螨病中也可发挥作用。在此，我们描述了葡萄牙大陆家猫中首例意外新恙螨感染病例。由于在秋新恙螨中发现了嗜吞噬细胞无形体和伯氏疏螺旋体的核酸，在意外新恙螨中发现了立克次氏体属，因此正确的分类鉴定对于了解这些螨类作为可能的病原体传播媒介的作用至关重要。
