Characterization of toxigenic genes of Bacillus cereus strains isolated from different spices sold in Algeria.

Many cooked foods are prepared with spices and dried herbs; these can be contaminated by several types of microorganisms, including aerobic spore-forming bacteria. The Bacillus cereus group is very widespread in nature and is known among the common food contaminants. They are involved in food poisoning, causing two types of syndromes, diarrheal and emetic.

Does Food Safety Knowledge Affect Attitudes and Practices? A Preliminary Study of Turkish Veterinary Students.

This study aimed to evaluate effects of the food safety courses that veterinary medicine students take during their education at Kirikkale University, Turkey, on the students' food safety knowledge, attitudes, and practices. A questionnaire comprising demographic, knowledge, attitudes, and practices sections was developed, and eight experts performed the clarity test. The questionnaire was pilot-tested by 35 students.

Plasmid-Mediated Colistin Resistance in O157:H7 Cattle and Sheep Isolates and Whole-Genome Sequence of a Colistin-Resistant Sorbitol Fermentative O157:H7.

The aims of this study were to investigate the plasmid-mediated colistin resistance genes (, , , , and ), phenotypic colistin resistance in O157:H7/H7 strains isolated from cattle and sheep, and whole-genome sequence (WGS) analysis of colistin-resistant sorbitol fermentative O157:H7. According to the results, 5 of the 49 isolates were found to harbor and/or genes. Three isolates, including a sorbitol fermentative O157:H7, were found phenotypically resistant to colistin with a minimum inhibitory concentration value of 128 μg/mL.

Prevalence and Characterization of Listeria monocytogenes Isolated from Beef and Sheep Carcasses in Turkey with Characterization of Locally Isolated Listeriophages as a Control Measure.

Swab samples from cattle and sheep carcasses (120 of each) were tested for Listeria monocytogenes, and 120 slaughterhouse wastewater samples were tested for listeriophages over 12 months (10 samples per month) to note the seasonal distribution. L. monocytogenes and bacteriophage isolates were characterized, and the biocontrol of L.
