Comparison of methods for isolation of mycobacteria from water

Article Abstract:

The efficacy of 12 isolation methods for mycobacteria are compared. Tryptic soy broth method or 0.05% cetylpyridinium chloride (CPC) can decontaminate surface water effectively. The 0.005% concentration of CPC is ideal for decontaminating the treated water. The ideal incubation temperature is 30 degrees centigrade. Lowenstein-Jensen medium is better culture media for water than Ogawa egg yolk, and ofloxacin and ethambutol.

Isolation of Mycobacteria from frozen fish destined for human consumption

Article Abstract:

Scientists have been able to detect non-tuberculous mycobacteria in frozen fish at a wholesale market that had been stored in sterile conditions at -18 to -22 deg C. Mycobacteria can survive under extremely adverse conditions, sometimes for years.

Predictive modeling of the shelf life of fish under nonisothermal conditions

Article Abstract:

Researchers describe a model that can predict the growth of pseudomonads in fresh fish under a variety of temperatures. This is important because most foods are subjected to widely varying temperatures during transportation and storage.
