Plain-English summary
A 4-day-old male Holstein calf was found to be dull, blind, and had rapid eye movements before being humanely euthanized. A necropsy revealed severe brain inflammation, eye problems, and joint infections. Tests showed the presence of a bacteria called Citrobacter koseri in several organs, indicating a serious infection. It was also determined that the calf had not received enough colostrum (the first milk rich in antibodies) from its mother, which likely contributed to its condition. Unfortunately, the calf did not survive due to the severity of the infection.

Abstract
A 4-day-old male Holstein calf with dull mentation, nystagmus and blindness was humanely destroyed and subject to necropsy examination. Gross lesions included severe suppurative meningitis characterized by diffuse cloudy thickening of the meninges, bilateral hypopyon and fibrinosuppurative polyarthritis affecting the hocks. Citrobacter koseri was isolated from the meninges, ocular fluid, synovial fluid, spleen and small intestine. Microscopically, there was neutrophilic and histiocytic meningitis with intralesional bacilli, endophthalmitis, neutrophilic splenitis and multiple renal microabscesses. Failure of passive transfer of colostrum was confirmed. This appears to be the first characterization of septicaemia in a calf caused by C. koseri, with lesions comparable with those described in human neonates.
