Gram positive Bacilli (28,92%) Staphylococci (27,27%), Micrococci (28.92%) and Gram-negative Bacilli (10,74%) respectively were the most abundant in the air from the studied farms. Other types of microorganisms were isolated in varying percentages. The isolated microorganisms included both pathogenic like Escherichia coli and non-pathogenic ones like some types of gram positive Bacilli. The results also showed that the type of system adopted in poultry farms in the study area has no significant role in the level of air contamination
