Infection

11.5K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Models of Health Promotion and Illness Prevention II

2.0K
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Environmental Applications of Microorganisms

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Transmission-based Precautions II: Airborne and Protective Environment

1.8K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Biological Methods for Microbial Control01:28

Biological Methods for Microbial Control

728
Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

Area of Science:

  • Ecology
  • Epidemiology
  • Mathematical Biology

Background:

  • Pathogens can survive in abiotic environments, complicating disease transmission.
  • Current models for environmental transmission lack clear links to pathogen ecology and spatiotemporal scales.

Purpose of the Study:

  • To present a conceptual framework for organizing microparasites based on abiotic environmental roles.
  • To analyze and compare mean-field and individual-based models for environmental transmission.

Main Methods:

  • Developed a conceptual framework for microparasite classification.
  • Analyzed and compared mean-field and individual-based modeling approaches for environmental transmission.

Main Results:

  • Identified significant divergence between modeling approaches under non-ideal mixing conditions and for rapidly evolving pathogens.
  • Highlighted the importance of pathogen lifecycle and system scales in model selection.

Conclusions:

  • Recommends tailoring environmental transmission models to specific pathogen lifecycles and host-pathogen system scales.
  • Emphasizes the need for ecologically informed modeling frameworks to accurately predict disease spread.
