Methods for imaging mammalian mitochondrial morphology: A prospective on MitoGraph.

Mitochondria are found in a variety of shapes, from small round punctate structures to a highly interconnected web. This morphological diversity is important for function, but complicates quantification. Consequently, early quantification efforts relied on various qualitative descriptors that understandably reduce the complexity of the network leading to challenges in consistency across the field.

Microbial Risk Analysis of Food in Canada.

The consideration in Canada of risk analysis for microorganisms in food by the Health Protection Branch (HPB) is in its formative stage. These analyses have become necessary because of the need for better control of imported and domestically produced food. A working group has been established between Health Canada and Agriculture and Agrifood Canada to consider a joint approach to risk analysis for foodborne microbiological hazards.

Health risk assessment of Listeria monocytogenes in Canada.

In this review, the major steps used in the formulation of a health risk assessment for Listeria monocytogenes in foods are discussed. Data is given on the numbers of human listeriosis cases reported in Canada along with the current Canadian regulatory policy on L. monocytogenes.

Prevention of foodborne listeriosis.

Listeria monocytogenes is a Gram-positive, rod-shaped bacterium which, although recognized in the medical literature as an opportunistic pathogen for the past 60 years, has only recently gained prominence as an important foodborne pathogen. Factors which make this organism unique among foodborne pathogens include its ability both to survive in foods under a variety of adverse conditions and to grow at low refrigeration temperatures. The organism is very widespread in the environment and can be found in a wide variety of foods.
