Utilization of fluorescent microspheres and a green fluorescent protein-marked strain for assessment of microbiological contamination of permafrost and ground ice core samples from the Canadian High Arctic

Article Abstract:

Fluorescent microspheres were applied in a novel fashion during subsurface drilling of permafrost and ground ice in the Canadian High Arctic to monitor the exogenous microbiological contamination of core samples obtained during the drilling process. Macroscopic examination in the field demonstrated reliable transfer of the microspheres to core samples, while detailed microscopic examination revealed penetration levels of less than 1 cm from the core exterior.

Molecular epidemiology of group A rotaviruses in water sources and selected raw vegetables in Southern Africa

Article Abstract:

Raw and treated drinking water supplies at plants in two geographic areas along with selected irrigation water and corresponding raw vegetables in three regions of southern Africa were screened for the presence of rotaviruses (RVs) using molecular techniques. The results provide new information on RV types in water and related environments and identify the potential risk of waterborne transmission.

Structure of sediment-associated microbial communities along a heavy-metal contamination gradient in the marine environment

Article Abstract:

The sediment-associated microbial communities are examined along a gradient of heavy-metal pollution in the marine environment. This information may be useful in predicting long-term effects of heavy-metal contamination in the marine environment.
