Clinical and epidemiological studies on respiratory manifestations in sheep [electronic reource].

Includes references.

2390 Living sheep of different ages (1-12 months), sexes and breeds (Braky- Rhmany- Baladi) were examined clinically in the field for investigation of the animals which suffered from signs of respiratory manifestation [nasal discharge (serous – mucoid - mucopurulent), rapid breathing, sever dyspenea, pyrexia (rectal temp 40-41 c). congested mucous membranes, lacrimation, coughing and abnormal lung sound by auscultation. The study was carried out on (150) pneumonic lambs. The morbidity rate was 6.2 % (150/2390), mortality rate was 7.4 % and fatality rate was 19.3 % (29/150). Bacteriological examination revealed that (75) samples were positive for bacterial growth with percentages (50%) from previously affected sites of samples. In total out of (127) bacterial isolates. Concerning Gram positive bacteria ; staphylococcus aureus was 10 (6.7 %) , streptococcus 8 (5.3 % ) , staphylococcus epidermidis 14(9.3 %).while the gram negative bacteria were identified as E,coli 30 (20%) Proteus sp 28 (13.3%) Enterobacter sp 9 (6%) klebseilla pneumoniae subsp pneumoniae 5 (3.4)% klebseilla ozaenae 7 (4.7 %), citrobacter diversus 6 (4%), pasteurella multocida 2 (1.3 %) , providencia 2 (1.3%) , pseudomonas aerugenosa 14 ( 9.3 % ) isolated from the different examined collected samples. Bacteriological examination for (14) lung samples revealed that staphylococcus aureus and Escherichia coli were isolated from two samples (14.2) % and other bacteria were mannheimia haemolytica , pseudomonas aerugenosa, Enterobacter agglumerans, Haemophillus somuns every one of them were isolated from one sample (7.1%). Only actinomyces pyogenes was isolated from three samples (21.3%). The bacterial examination of lung samples showed that ; all isolates were single such as actinomyces pyogens from two samples (14.2) , mannheimia haemolytica , haemophillus somnus Enterobacter agglomerans , Staph .aureus every one of them was isolated from one samples (7.1) % . Except two isolates were isolated from mixed cultures ; Escherichia coli + Actinomyces pyogenes and E.coli +Staph aureus .Every isolates was isolated from 1sample (7.1%). Sensitivity test revealed that most isolates were highly sensitive to Enrofloxacin, Cephaloexine, and Ampicillin and were resistant to streptomycin
