Question

What factors might account for the diversity of microbes in a specific environment? (four environmental surveillance techniques developed by microbiologists)

Answer 1

They focus on particular physical and chemical variables such as calculating temperature, pH, and salinity within a given geography to formulate a distinction between microbial communities and the ecosystem that can be tolerated by different organisms.

Four environmental surveillance techniques developed by microbiologists are-

1. Microbiologic Sampling of the Environment

2. Air Sampling- Biological contaminants occur as aerosols in the air and may contain bacteria , fungi, viruses and pollen. Aerosols are characterized as particles suspended in air, both solid or liquid. Talking for 5 minutes and coughing will create 3,000 droplet nuclei each; sneezing will generate around 40,000 droplets and then evaporate to particles in the size range of 0.5–12 μm.Particles in a biological aerosol typically varies in size from < 1 μm to about 50 μm.

3. Water Sampling- Water sampling in health-care settings is used to detect clinically important waterborne pathogens or to determine the quality of finished water in the distribution system of a facility. Routine water monitoring in a health care facility is not typically required, although sampling in support of disease investigations may help establish effective methods for preventing infections.

4. Environmental Surface Sampling- Routine environmental-surface sampling (e.g. surveillance crops) in healthcare settings is neither cost-effective nor justified. If indicated, surface sampling should be carried out with multidisciplinary approval in compliance with carefully considered action plans and policies.
