Study Notes
Introduction to Public Health Microbiology
- Public health focuses on improving the health of populations through education, promotion, disease prevention research, and response to infectious diseases.
- Careers in public health microbiology include scientists, epidemiologists, policymakers, nurses, health educators, physicians, and restaurant inspectors.
Functions of Public Health Professionals
- Develop strategies for outbreak response.
- Test biological and environmental samples.
- Monitor air and water quality.
- Implement vaccination programs.
- Enhance healthcare for mothers and children.
- Investigate outbreaks of infectious diseases.
- Design and analyze public health policies.
Microbes Overview
- Microbes encompass prokaryotic and eukaryotic organisms, as well as acellular infectious agents.
- Prokaryotes: Single-celled organisms lacking a nucleus and membrane-bound organelles, including bacteria and archaea.
- Eukaryotes: Organisms with a nucleus, including algae, fungi, protozoa, and helminths (worms).
Types of Microbes
- Prokaryotic Microbes: Bacteria (both pathogenic and non-pathogenic) and archaea (environmental extremophiles).
-
Eukaryotic Microbes:
- Algae: Photosynthetic, mostly single-celled, few cause human disease.
- Fungi: Decomposers that can be pathogenic.
- Protozoa: Single-celled, motile, some are pathogenic.
- Helminths: Microscopic life stages, diagnosed microscopically.
- Arthropods: Insects that transmit diseases.
Acellular Infectious Agents
- Viruses: Composed of DNA or RNA with a protein coat, reliant on host cells for replication.
- Viroids: RNA without a protein coat, also depend on host machinery.
- Prions: Misfolded proteins that induce other proteins to misfold.
Historical Perspectives in Public Health Microbiology
- Early understandings of disease included isolation of affected individuals and beliefs about "bad air."
- Greek philosophers suggested environmental factors led to disease; Hippocrates refuted supernatural causes.
- John Snow's mapping of cholera outbreaks marked the birth of epidemiology.
Germ Theory and Microbiology Milestones
- Germ theory established that microorganisms can cause disease, challenging previous beliefs in spontaneous generation.
- Key contributors: Francesco Redi demonstrated maggots come from eggs, not spontaneously; Louis Pasteur proven that microorganisms cause fermentation and spoilage.
- Robert Koch's postulates provided a framework for linking specific microbes to diseases, notably anthrax and tuberculosis.
Vaccination and Disease Control
- The implementation of vaccines began with smallpox vaccination and expanded to various diseases in the early 1900s.
- Vector control initiated with the discovery of mosquitoes transmitting diseases, leading to swamp drainage and insecticide use.
Recent Global Health Concerns
- Ebola outbreak in 2014 resulted in 932 deaths.
- Zika virus raised alarm in 2016, prompting global health discussions.
- The SARS-CoV-2 pandemic in 2019 highlighted the need for understanding and controlling zoonotic diseases.
Coronavirus Transmission
- Coronaviruses are zoonotic, enabling transmission between animals and humans.
- Human-to-human transmission is primarily via respiratory droplets from close contact with infected individuals.
