Two groups of calves were subjected to dietary stress by withholding of food beginning 1 or 14 days after inoculation with 10(10) CFU of Escherichia coli O157:H7. Following treatment, neither group had a significant increase in fecal shedding of E. coli O157:H7. A third group of calves had food withheld for 48 h prior to inoculation with 10(7) CFU of E. coli O157:H7. These calves were more susceptible to infection and shed significantly more E. coli O157:H7 organisms than calves maintained on a normal diet.

Effect of active composite coating based on nanochitosan-whey protein isolate on the microbial safety of chilled rainbow trout fillets packed with oxygen absorber.

Article Synopsis
- This study evaluated how a coating made from nanochitosan and whey protein isolate, combined with summer savory essential oil and oxygen absorber packaging, affects the growth of specific bacteria on rainbow trout fillets stored in the fridge.
- Results showed that while Listeria monocytogenes initially decreased in all treatment groups, it eventually increased, indicating limited effectiveness of the treatments against this bacterium.
- In contrast, the combined treatment with the coating, essential oil, and oxygen absorber was most effective in slowing the growth of E. coli and reducing Pseudomonas aeruginosa levels compared to other methods.

Article Synopsis
- * Out of 544 samples analyzed from 272 bovine carcasses, 11 tested positive for O157:H7 (4.0%), and 6 of those had specific pathogenicity genes detected.
- * Additionally, 22 carcasses (8.0%) tested positive for the unspecified pathogen, but none contained the specific genes associated with pathogenicity.

To evaluate the typing and clinical application effect based on clustered regularly interspaced short palindromic repeats (CRISPRs), serotype, and Multilocus Sequence Typing (MLST). The spacers, serotype and sequence type (ST) were obtained with CRISPRsFinder, SeroTypeFinder and MLST. PCR was used to amplify the CRISPRs, and the spacers were used to predict serotype and ST, then comparing with the serotype and ST.

Rapid measurement of waterborne bacterial viability is crucial for ensuring the safety of public health. Herein, we proposed a colorimetric assay for rapid measurement of waterborne bacterial viability based on a difunctional gold nanoprobe (dGNP). This versatile dGNP is composed of bacteria recognizing parts and signal indicating parts, and can generate color signals while recognizing bacterial suspensions of different viabilities.

Article Synopsis
- Antibiotic resistance is a major global health issue, prompting researchers to seek alternative treatment methods.
- Molasses shows promising antimicrobial properties that may help combat resistant bacteria by disrupting bacterial cell membranes and proteins.
- The study found that although molasses did not work synergistically with phages, it increased the size of phage plaques and enhanced their activity, suggesting potential benefits of using molasses alongside phage therapy.
