Convergence Retraction Nystagmus Secondary to Central Nervous System Disseminated Coccidioides Immitis Infection in a Dog.

This report describes a Belgian Malinois dog residing in metropolitan Phoenix, Arizona that was presented to a veterinary neurology center with abnormal eye movements as his only clinical sign. On examination, clinical signs were isolated to convergence-retraction nystagmus. A brain MRI was performed which identified two well-demarcated, T2-hypointense and T1-isointense, avidly contrast enhancing mass lesions with moderate to severe perilesional T2 and FLAIR hyperintensity within the left frontal lobe and left dorsal midbrain.

Development of a rapid lateral flow assay for detection of anti-coccidioidal antibodies.

spp. are dimorphic fungi that are capable of infecting human and non-human mammals and can cause diverse manifestations of coccidioidomycosis or Valley fever (VF). In combination with clinical symptoms and radiographic findings, antibody-based diagnostic tests are often used to diagnose and monitor patients with VF.
