The expression of ammonia monooxygenase encoding mRNA (amoA mRNA) in a wastewater treatment process was analyzed in an attempt to propose an effective target for the monitoring of nitrifying bacteria in engineered systems or natural environments.
Monitoring of these bacteria, which may be associated with foodborne diseases in humans, is one of the great objectives of the poultry industry, since salmonellosis leads to severe economic losses.
Real application of NIR spectroscopy as accurate, fast, and noninvasive method for monitoring of growth of bacteria in meat and milk are presented.
We tested the ability of LF82Δhfq to invade epithelial cells and resist phagocytosis in cultured macrophages by performing gentamycin protection assay monitoring the number of bacteria entering cell monolayers.
Plasmid pGEN206, which expresses the fluorescent reporter protein GFPuv, encoded by gfpuv, was used to monitor efficient lysis of bacteria by fluorescence microscopy.
Alternatively, to determinate whether Salmonella can spread from leaf-to-leaf, we syringe-infiltrated single leaves and monitored the presence of bacteria in non-infiltrated neighbouring leaves two weeks later.
Attempts to monitor the movement of bacteria through the digestive system led researchers to introduce tracers, such as mineral oil or pigments, into the liquid media [14].
Further studies are needed to monitor the kinetics of bacteria DNA appearance and clearance from the blood during infection and antibiotic treatment.
This approach was previously successfully applied on the recognition and monitoring of other food/spoilage bacteria tested in similar experiments [31, 33].
Monitoring of multi-resistant bacteria is insufficiently.
