    This study was conducted to detect the presence of rope-producing Bacillus spp. and the rope spore counts in one hundred samples of different types of bread obtained from several bakeries and supermarket stores in Bursa province and to identify the isolates at the species level. Rope spore counts determined using the Most Probable Number (MPN) technique varied between 30 and 90 MPN/g in eight samples while this count was 11 000 MPN/g in one sample. By VITEK 2 bacterial identification system, eight of Bacillus strains isolated were identified as B. cereus and one as B. subtilis. Additionally, it was observed the growth of yeast and mould in the counts varying between 1x102 and 6.3x104 cfu/g in the samples. The results indicated that breads analysed harboured Bacillus species which can be responsible for rope spoilage of bread or food poisoning in humans
