ABSTRACT

Morán J, Martínez R, Gómez  L, Alonso JM, Duque J, Ginés JA, Pérez EJ., Neosporosis in calf unusual neurological presentation, Onl J Vet Res., 28 (10): 752-757, 2024. We describe clinical and pathological findings from a 15 day old Limousine calf with incoordination and limb paralysis. Tissues were cultured for aerobic and microaerophilic organism. For microscopy, nervous tissues and hematology were determined and for serology, antibodies to Neospora caninum by ELISA. In brain cortex, we found non-suppurative meningoencephalitis, necrosis and apoptosis in neurons. In heart, we observed interstitial myocarditis, degeneration and necrosis with leukocyte infiltration. Liver presented periportal mononuclear cells with necrotic foci. We found moderate leucopenia of 3.2 x 103μl, elevated creatine phosphokinase 176 UI/L suggesting muscle damage. Multifocal encephalitis with myocarditis is strongly suggestive of Neospora spp.

 

Key words: Calf, Neospora caninum, brain, encephalitis.
