Pediculus humanus capitis (Head Lice)
Long-term infections can lead to chronic diseases or complications
Chronic Conditions
can invade tissues and organs, causing inflammation and tissue damage
Infection
is a microorganism that causes disease
Pathogen
They generally consist of an outser cell wall that contains a liquid called
Protoplasm
These are microbes that can cause disease. Examples include certain bacteria, viruses, fungi, and parasites.
Pathogenic Organisms
what is a single bacterial cell that divides into two identical cells, referred to?
daughter cells
contact with nonintact (broken) skin, blood, body fluid or other potentially infectious materials that is the result of the performance of an employee’s duties.
Exposure incident
There are what? Fungi, Bacteria, Parasite, Viruses
Pathogens (types of pathogens)
The study of _______ is known as mycology.
Fungi
Pathogenic bacteria can multiply rapidly, sometimes doubling in number every _______ under ideal conditions
20 minutes
They consist of genetic material (either DNA or RNA) encased in a protein coat (capsid) and sometimes a lipid envelope. They lack cellular structures
Virus(es)
that can disrupt cellular functions or trigger severe immune responses
Toxin Production
Pus-forming bacteria arranged in curved lines resembling a string of beads.
Streptococci
- Affects the liver and can lead to chronic illness
HBV (Hepatitis B Virus)
Form clusters resembling grapes.
Staphylococci
Spiral or corkscrew-shaped bacteria.
Spirilla
These microbes typically do not cause disease and may even be beneficial, such as those involved in digestion or maintaining skin health.
Non-Pathogenic Organism
reproduce asexually through binary fission, where a single cell divides into two identical cells - daughter cells
Bacteria
causes gonorrhea and causes meningitis
Diplococci
A process that completely destroys all microbial life, including bacterial spores.
Sterilization
Can lead to AIDS and compromise the immune system
HIV (Human Immunodeficiency Virus)
During this stage, bacteria grow and reproduce. Bacteria multiply best in warm, dark, damp or dirty places.
Active Stage
coat themselves in a wax-like outer shells.
Inactive or Spore-forming stage
IT INVOLVES UNDERSTANDING THE STRUCTURE, FUNCTION, CLASSIFICATION, AND BEHAVIOR OF BACTERIA, AS WELL AS THEIR ROLES IN VARIOUS ENVIRONMENTS, INCLUDING HUMAN HEALTH, AGRICULTURE, AND ECOLOGY.
