Candidiasis is one of avian fungal diseases that can affect poultry flocks. Candida albicans is considered as normal flora of birds which can be pathogen under certain circumstances. Hence the prevalence of subclinical disease causes delayed growth and loss of weight gain. In present study, 600 broilers were sampled randomly from 10 poultry farms. Each broiler was weighted and tracheal samples were caught by swab dropping technique. Samples were cultured on 37 degree of centigrade. Further tests were applied for positive samples. 47 out of 600 samples were positive. Prevalence of subclinical candidiasis in broiler flocks around Urmia was 7.83%. Based on chi square, the prevalence of subclinical candidiasis and mean flocks weight has significant correlation (α ≤ 0.05). Prevalence of subclinical candidiasis instead of economic significance, May reflects different problems such as irresponsible use of antimicrobial agents, presence of immunosuppressive factors and etc.
