Epidemiological and clinical studies on respiratory affections of sheep

minufiya veterinary journal 01/2008; 5(2):341-352.


Respiratory affections of sheep considered as 0ne of the most serious problems affecting sheep production and causing sever economic losses. In ths study we study the pattern of repiratory affections occurrence in sheep flocks of different breed . we concluded that repiratory mainfestation occure in two manner the first one is sever with fever, cough , mucopurulent nasal discharge and depression with high chest abnormal sound. The other from was less sever with prolonged cough and thick muciod discharge and poor weight gain. The relation between the incidence of respiratory affections occurrence and pattern of sheep rearing , season, age ,sex and breed had been studied. The end result showed that significant correlation between the incidence of the respiratory affections occurrence and first three factors but non signficant correlation with the last two factors.
The pathological changes in lung tissue had been studied in relation to etiology to determine the severity of affection of the aetiological agent.

    ABSTRACT: ExtractFor many years chronic and subacute pneumonia has been recognized as a common finding in the lungs of lambs at slaughter throughout New Zealand. While the effect of the disease on weight gain is not clear, there can be no doubt that residual pleuritis is an important cause of economic loss through high condemnation rates of carcasses.

    ABSTRACT: Nasal secretions were collected from healthy lambs from flocks in Iowa and the surrounding states for 2 consecutive years. The 1st year, 322 lambs from 61 flocks yielded 202 Pasteurella haemolytica isolates, representing 9 established serotypes and 30 untypeable isolates. The 2nd year, 249 lambs from 49 flocks yielded 73 isolates, representing 9 established serotypes and 7 untypeable isolates. More isolates belonged to serotype 2 than to any other serotype. Serotypes 3, 4, and 10 (members of biotype T), were not isolated. Serotype 12 was also isolated and identified.

    ABSTRACT: 330 sheep from two different flocks were examined for respiratory manifestations including serous to mucopurulent nasal discharge dyspnoea, cough and light depression. 55 animals were sick (16.6%) and 13 died (3.9%). Samples were taken from healthy, diseases and dead cases as well. Pasteurella haemolytica A2 was identified from 18 isolates, and serotyped by rapid plate agglutination (RPA). Drug susceptibility was tested and treatment applied in line with the results.
