A novel paper-based and pH-sensitive intelligent detector in meat and seafood packaging.

The annual amount of food waste or loss is about one-third of the total edible food globally produced for human consumption. Continuous and real-time monitoring by spoilage detectors can significantly reduce food waste. A novel paper-based pH-sensitive meat spoilage detector was developed.

Identification and expression profiles of multiple genes in Nile tilapia in response to bacterial infections.

To understand the molecular mechanisms involved in response of Nile tilapia (Oreochromis niloticus) to bacterial infection, suppression subtractive cDNA hybridization technique was used to identify upregulated genes in the posterior kidney of Nile tilapia at 6h post infection with Aeromonas hydrophila. A total of 31 unique expressed sequence tags (ESTs) were identified from 192 clones of the subtractive cDNA library. Quantitative PCR revealed that nine of the 31 ESTs were significantly (p<0.

Chemotactic factors of Flavobacterium columnare to skin mucus of healthy channel catfish (Ictalurus punctatus).

To gain an insight into the chemotactic factors involved in chemotaxis, we exposed a virulent strain of Flavobacterium columnare to various treatments, followed by analysis of its chemotactic activity. The chemotactic activity of F. columnare was significantly (P<0.
