Klebsiella pneumoniae was incriminated in respiratory outbreaks in barki lambs in Bedouin's herds in north western coastal zone of Egypt. Morbidity and mortality reached 40% and 19 % respectively in lambs, in which respiratory signs were observed and multifocal abscesses were recorded in necropsy. Klebsiella pneumoniae was recovered from diseased and dead lambs. Isolated Klebsiella pneumoniae found to be most sensitive to Imipenem, Gentamycine; Amikacin and Ciprofloxacin as antimicrobial agents but resistant to Tetracycline and Co-trimoxazole. Internal multifocal abscessiation in lambs which was recorded, is found to be a major health problem as it is difficult to be diagnosed clinically and need further
investigations and studies.
