Reijmerink)  \nSporadic cases of trombiculiasis have been reported as causing neurologic signs in dogs. We report a cluster of trombiculiasis cases (outbreak) in the province of Noord-Holland, the Netherlands, associated with Neotrombicula autumnalis mite infestation. Veterinarians should consider N. autumnalis infestation in differential diagnoses for acute onset neurologic signs in dogs.  \nDOI: [http://doi.org/10.3201/eid3112.241758](http://doi.org/10.3201/eid3112.241758)  \nNeuatertowxiitcholopagicrasiiesso, rdoferswhinichdotigcsk  \ncan be associbite paralysis  \nis an example (1–3) . Ticks commonly associated with acute flaccid paralysis in animals are Dermacentor variabilis, D. andersoni, and Ixodes holocyclus (1–3) . In the Netherlands, parasite-associated neurotoxicologic syndromes are not commonly included in differential diagnoses lists. However, members of themite family Trombiculidae (chigger or harvest mites) are represented in the Netherlands, among them Neotrombicula autumnalis. N. autumnalis larvae are ≈0.2 mm in length, bright orange, with 6 legs, a rectangular scutum bearing 3 pairs of setae, and 5-segmented palps with a characteristic trifurcate seta on the third segment. Trombiculiasis (trombiculosis, trombidiosis) is the skin condition most associated with larvae infestation of this mite family. Researchers have reported sporadic cases of dogs with neurologic signs concurrent with trombiculiasis (4,5) . We document a cluster of dogs whose owners sought veterinary care for observed neurologic signs presumptively associated with N. autumnalis infestations.  \nIn August 2024, owners sought care for a 9.5-yearold male Finnish Lapphund at a veterinary clinic near Edam, the Netherlands (Noord-Holland province) . The dog demonstrated acute progressive signs, including vomiting, hyperpnea, licking and biting between toes (itch), salivation, hyperthermia (39.5°C; normal 38°C–39°C), and generalized ataxia and paresis. Clinicians observed red-orange mites, morphologically identified as N. autumnalis, on the skin of  \nthe paws and abdomen and concurrent erythema. An injection of dexamethasone administered 1 day prior to the dog’s arrival at the clinic relieved some signs (itch), but owners observed progressing neurologic signs. The dog was alert and responsive, but no longer ambulatory 12 hours after onset; attempts at rising were unsuccessful. Because of the severity of the neurologic signs, the owners elected euthanasia.  \nIn the same week, 3 more dogs arrived at a veterinary clinic in the Edam area. Those dogs showed acute progressive signs, including generalized proprioceptive ataxia and paresis; itch, predominantly of the interdigital regions of all 4 paws; interdigital erythema; hyperthermia; vomiting; and hyperpnea. Clinicians noted N. autumnalis aggregations on the skin of the paws and abdomen. In 2 cases, dog owners reported seeing red-orange stains between digits, which upon closer examination were identified as large accumulations of mites. During a brief period, all dogs were nonambulatory. Details provided by 1 of the dog owners included an acute onset of ataxia and paresis, most notably in the pelvic limbs (Video, [https://wwwnc.cdc.gov/EID/article/31/12/24-](https://wwwnc.cdc.gov/EID/article/31/12/24-)[ ](https://wwwnc.cdc.gov/EID/article/31/12/24-)[1758-V1.htm](1758-V1.htm)), which progressed over 48 hours to anonambulatory state. Thereafter, that dog showed progressive recovery of neurologic function.  \nAll 3 dogs received treatment, including injections with corticosteroids, application of detergents to the paws, and topical ectoparas","cbCaiiJgYZd1Duas","https://ap.wps.com/l/cbCaiiJgYZd1Duas","pdf",272904,"English","# Case cluster and clinical presentation\n# Diagnosis considerations and mite identification\n# Treatment and outcomes\n# Epidemiologic investigation and public health response\n# Literature context","[{\"question\":\"What condition links neurologic signs and dogs in this report?\",\"answer\":\"The report links acute neurologic signs to trombiculiasis associated with Neotrombicula autumnalis mite infestation.\"},{\"question\":\"Where in the Netherlands did the cluster occur and what drove investigation?\",\"answer\":\"Cases occurred in Noord-Holland, particularly around the Edam area, and veterinarians and local authorities were notified after owners sought care.\"},{\"question\":\"How were the dogs treated and what were the outcomes?\",\"answer\":\"Dogs received corticosteroids and supportive measures including paw detergents and topical ectoparasiticides; two nonambulatory dogs regained ambulation within 12 hours, while one dog was euthanized due to severe progressive neurologic signs.\"}]","Trombiculiasis in 4 Dogs with Neurologic Signs, the Netherlands, 2024 | PDF"]
