» “Paralytic” Mastitis (Holstein)

A Holstein cow approximately 3 months pregnant, following severe peracute mastitis in the left hind quarter, presents with hindquarter paresis, accompanied by a general toxic state, anorexia, lack of rumination, and hyperthermia.
Paralytic mastitis is generally caused by the pathogenic action of certain bacteria: E. coli, Clostridia, Staphylococcus aureus, and Pseudomonas aeruginosa. In addition to mammary tissue damage, these infections are consistently accompanied by significant metabolic imbalances, generally due to the release of toxins. Despite the breeder's therapy with ketoprofen, 3 liters of 7.5% hypertonic NaCl IV, and the administration of 15 L of water PO, the animal shows no significant signs of improvement. The quarter is very hard and hot, and the animal remains recumbent, does not eat, and does not ruminate.
