Respiratory infections which commonly occur in sheep and goats often result from adverse physical and physiological stress combined with viral and bacterial infections. Inevitably, Pasteurella haemolytica pneumonia occurs as a result of these interactions. In this review, we present recent advances in research on the complex etiology of pneumonia involving P. haemolytica. Initially stress, indu...

Eighty-one barn owls (Tyto alba) and five Hawaiian owls or pueo (Asio flammeus sandwichensis) from Kauai, Oahu, Lanai, Molokai, Maui and Hawaii (USA) were evaluated for cause of death, November 1992 through August 1994. The most common cause of death in barn owls was trauma (50%) followed by infectious disease (28%) and emaciation (22%). Most traumas apparently resulted from vehicular collision...

Bovine pasteurellosis is known by a number of synonyms that are descriptive of the condition and are relevant in specific circumstances. The terms shipping fever, transit fever, bovine enzootic pneumonia, and bovine respiratory disease (BRD) complex are all very meaningful terms used to describe the disease. It is believed that in the United States, the losses to the beef and dairy industries f...

Bronchopneumonia is a population-limiting disease in bighorn sheep in much of western North America. Previous investigators have isolated diverse bacteria from the lungs of affected sheep, but no single bacterial species is consistently present, even within single epizootics. We obtained high-quality diagnostic specimens from nine pneumonic bighorn sheep in three populations and analyzed the ba...

Leukotoxin-producing Mannheimia haemolytica consistently causes fatal pneumonia in bighorn sheep (BHS) under experimental conditions. Surprisingly, by culture methods, it has been isolated from pneumonic BHS lungs less frequently than other bacteria. However, in one study PCR assays detected M. haemolytica from over 70% of the pneumonic lung samples that were negative for this organism by cultu...

The pneumonic adenocarcinoma (P-ADC) is defined as primary lung ADC with a radiological pneumonic presentation, usually referred to histologically as ADC with a mixedinvasive and BAC (bronchioloalveolar carcinoma) predominant subtype in the 2004 WHO classification. Invasive mucinous adenocarcinoma (IMA) formerly classified as mucinous BAC usually presents consolidative opacities mimicking pneum...

BACKGROUND Despite the paucity of data available, stall-side serum amyloid (SAA) assays are commonly used to make diagnostic and treatment decisions in foals with bronchopneumonia. HYPOTHESIS Measurement of SAA concentrations can accurately differentiate pneumonic from healthy foals. ANIMALS Fifty-four pneumonic foals between 3 weeks and 5 months of age were compared to 44 healthy controls....

Isolation of Pasteurella multocida was attempted from the heart blood, spleen, liver and lung collected from rabbits (4 No,s) suspected to have died of pasteurellosis. A total of four P. multocida isolates were isolated and identified on the basis of biochemical characteristics, pathogenicity studies in mice and PM-PCR. The In vitro antibiotic sensitivity test of the organisms was conducted whi...

Abstract BACKGROUND: SP-A and SP-D are hydrophilic proteins which regulate the inflammatory response of the lung. Pasteurella multocida is one of the most common bacteria isolated from calves suffering from shipping fever pneumonia, one of the most problems in dairy herds. OBJECTIVE: Evaluation of surfactant content may provide a valuable diagnostic tool for detection of calf pneumonia due to ...
