Evidence that Blood-borne Infection is Involved in the Pathogenesis of Bovine Pneumonic Pasteurellosis

Pneumonic pasteurellosis in a goat

A3-year-old goat weighing 40 kg was presented to the LargeAnimal Unit, University Veterinary Hospital, Universiti PutraMalaysia with complains of in appetence, lateral recumbency,and weakness. Physical examination findings were pyrexia,tachycardia, tachypnea, and pale mucous membrane. Harsh andcrackles lung sound was noticed upon auscultation. The case wastentatively diagnosed as pneumonic past...

The clinical efficacy of enrofloxacin in the treatment of experimental bovine pneumonic pasteurellosis.

The clinical efficacy of enrofloxacin was tested in calves with experimentally induced pneumonic pasteurellosis. A strain of Pasteurella haemolytica, biotype A, serotype 1 (P. haemolytica A1), which had been isolated from an outbreak of pneumonic pasteurellosis in feedlot calves, was used to induce the disease in 24 eight-month-old calves. Each animal received, by intratracheal injection, 6 x 1...

A Review on Pneumonic Pasteurellosis (respiratory Mannheimiosis) with Emphasis on Pathogenesis, Virulence Mechanisms and Predisposing Factors

Pneumonic pasteurellosis is one of the most economically important infectious diseases of ruminants with a wide prevalence throughout the continents. The disease is characterized by an acute febrile course with severe fibrinous or fibrinopurulent bronchopneumonia, fibrinous pleurisy and septicaemia. Infected animals may die within a few days of the onset of clinical signs, but those which survi...

Experimental reproduction of acute pneumonic pasteurellosis in rabbits.

A histomorphometric and physiopathological study was made of the lung parenchyma of Belgian White SPF rabbits infected experimentally with Pasteurella multocida type A. Symptoms observed were characteristic of the acute respiratory syndrome. Mean serum cortisol concentration and rectal temperature increased in all experimental groups. Histopathological changes included alveolitis and leukocytic...
