Blood cultures in dogs yield
positive results in about 45 % to 75 % of cases, and
urine cultures are
positive in about 25 % to 50 % of cases.1 Serologic testing for Brucella antibody and Aspergillus antigen may be performed.5 Cerebral spinal fluid
analysis is often normal, but increased protein concentration (albuminocytologic dissociation) or a neutrophilic pleocytosis is occasionally observed.1 When
urine, blood cultures, and serology have not identified a cause, CT or fluoroscopy - guided fine - needle aspiration of the infected disc space may be performed under general anesthesia, or a surgical biopsy specimen from the lesion can be obtained for culture.
