White spotted kidney in a bovine
This pictures are characteristic of a subacute interstitial nephritis, also known as white spotted kidney.
This lesion is characterized by irregular whitish areas, of up to 1 cm in diameter in the renal cortex which do not normally protrude towards the renal capsule, extrend into the parenchyma and are non suppurative. When the lesion is more chronic the kidney surface becomes rugous and even shows areas of parenchymal retraction. This is a fairly nonspecific lesion but has been associated with infections by Escherichia coli, Leptospira spp. or other bacteria.
A similar lesion was published a couple of years ago in sheep.
Kidney with whitish spots of miliary distribution.

¿Estas lesiones pueden afectar al ser humano? Entiendo que son causa de decomiso en matadero, ¿verdad? Muchas gracias.
Comment form LinkedIn user: Possible causes will differ according to where you are in the world. In South Africa we would also consider a number of protozoal and viral diseases, amoung others.
Comment from LinkedIn: Such a classic. We saw so many of these in the slaughterhouse material we received for teaching. Good to see stuff like this on a regular basis, now that I’m doing mostly mouse pathology.
