| Popis: | Bacillus spp. are foodborne pathogens important in food contamination, especially in dried milk products. They are associated with foodborne outbreaks, spoilage of dairy products (sweet curdling and bitterness), and bovine mastitis. This study investigated the contamination rate of Bacillus spp. in a total of 105 samples of the dried milk products kishk, Cerelac and whole milk powder, marketed in Assiut city, Upper Egypt. The identification of the Bacillus spp. strains was completed using conven-tional biochemical methods and PCR protocols for the confirmation of isolates. Bacillus spp. were isolated from 57 out of 105 (54%) [95% CI: 44.664.0%] of the examined samples at levels of up to 7.7 log10 cfu/g. The prevalence of Bacillus spp. was significantly (P |
