Plain-English summary
A sick 11-day-old Holstein bull calf was brought in with diarrhea and a low-grade fever that lasted four days. As the calf's condition worsened, it became very lethargic and unresponsive, showing weakness in all its limbs and neck. Tests on its spinal fluid suggested it had viral meningitis or encephalitis, and a virus called Aichivirus B was found. This virus is known to affect various species, but its link to neurological issues in calves is not well understood. Unfortunately, the outcome for this calf was not detailed in the study.

Abstract
An 11-d-old Holstein bull calf was presented to the Veterinary Medical Teaching Hospital at the University of Wisconsin-Madison because of a 4-d history of diarrhea and persistent low-grade fever. Initial diagnosis was enteritis caused by Cryptosporidium and rotavirus. During hospitalization, the calf became stuporous and was only responsive to noxious stimuli, with hypotonia of all 4 limbs, tail, head, and neck. A cerebrospinal fluid analysis revealed xanthochromia, with marked lymphocytic pleocytosis, which was suggestive of viral meningitis and/or encephalitis. Aichivirus B, which belongs to the Kobuvirus genus, was tentatively identified in spinal fluid by next-generation DNA sequencing. This virus can affect a multitude of species, including humans and cattle, and has been isolated from both healthy and diarrheic individuals. However, to date, a possible connection with neurologic disease has not been described, to our knowledge.
