A two years survey (1990-1991) was carried out to determine bacterial respiratory pathogens of cattle. A total of 350 samples collected from the respiratory system of cattle, of which 200 from the slaghterhouse, 50 from apparently healthy cattle. 50 from streassed animals and 50 from animals with respiratory affactions. Examination of these samples resulted in isolation of 123%, 143%, 186% and 182%c respectively. The results showed that 325 animals were positive with a incidence of 92.9°7. Of those 194 cases (59.7% showed mixed infection and 131 cases (40.3%) had one bacterial isolate in a pure form in culture. The total numbers of were 497 (142%) of which, 137 Staphylococcus, 32 Streptococcus, 74 E. coil, 24 Proteus spp., 31 Corynbacterium spp., 57 anthracoides, 15 Pasteurella spp., 24 Kliebseilla spp. 14 Citobacter spp., 10 Serratia spp. and 16 Pseudomonas spp. Bameriosogicla examination of 150 nasal swabs from human beings that were in contact with there animals (abattoirs and farms) resulted in 25 bacterial isolates. These were 8 Staph., 4 strep., 11 anthracoides and 2 Klebseilla. The pathogenic strains were Staph. aureus (3), Srep. Pyogenes (1) and Kiebseilla (2) . The non-pathogenic isolates (12% ) were Staph. albus (3), Staph. citrus (2), strep. fecalis (3) and anthracoides (11).
