ABSTRACT In the present work is discussed the importance to identify the bacterial, potentially pathogenic flora present in the respiratory tract of the calves and its relation with the ambient in order to define prevention and control programs. It was achieved the isolation in 66.1% of the samples taken in the high plain and 56,4% from the down plain, with predominance of P. multocida (65.4%) in the high plains, whereas in the down Streptococcus sp. Hemolytic was dominant (90.9%). In addition, it was identified in the high plain Streptococcus sp. hemolitic (30.9%), Arcanobacterium pyogenes (1.70%), Manheimia haemolytica (0.80%), and Staphylococcus sp. pathogen (0.8%). In the low plains it was identified P. multocida (4.5%) and Manheimia haemolytica (4.5%). The results evidenced that the ambient influenced the bacterial flora present and it is necessary its determination to evaluate the risk of respiratory diseases
