Classification of Biological Kingdoms

Carolus Linnaeus Developed system for both naming species and organizing them into groups Genus- group of species that have similar characteristics

Kingdoms There are six kingdoms that have been classified in the realm of science Archeabacteria Eubacteria Fungi Protists Plants Animals

What ways are they grouped Scientist group these various species by 4 things cell structure their habitats the way they eat and process food how they reproduce (mate)

How Archeabacteria & Eubacteria are Similar Have similar traits They both lack a nucleus (brain of the cell) Microscopic ( small to see with your eyes) Single-celled organisms-Prokaryotic Produce (reproduce) by dividing in half

Differences Archeabacteria Found in extreme conditions (hot or cold) Example: Thermophils Reproduce by dividing in half Daughter cell =mother cell Eubacteria Found in soil or bodies of animals Example: E.coli located in human intestines and aids in digestion and production of vitamin K12 Bad affect, it can cause food poisoning Also reproduces by dividing in half

Bacteriology Archeabacteria & Eubacteria

Bacteria One-celled microorganism that have both plant and animal characteristics There are two types Nonpathogenic Pathogenic

Why we need bacteria What are some examples of why we needs them? Some break down dead waste and return nutrients (nitrogen & phosphorus) back into the soil Need nitrogen form protein to aid in genetic synthesis Allow organisms (us) to gain nutrients from food

Pathogenic Nonpathogenic They are harmless organisms May perform useful functions Do not cause diseases or harm Ex. Used in making medicine, cheese, yogurt, help breakdown food and protect against infection in the human body Harmful microorganisms Cause disease of infections in humans Invade the body

Types of pathogenic bacteria 1. Cocci- round-shaped bacteria that appear single in a group 2. Staphylococci- pus-forming bacteria that grows in clusters (causes- abscesses, pustules, and boils) 3. Streptococci- spherical bacteria that grows in pairs (can produce strep throat and blood poisoning) 4. Diplococci- spherical bacteria that grows in pairs (can cause pneumonia) 5. Bacilli- short rod-shaped bacteria and are the most common (cause tetanus, tuberculosis, and typhoid fever 6. Spirilla- spiral or corkscrew- shaped (some can cause syphilis and Lyme disease)

Diplococci Staphylococci Spirilla Streptococci

Communicable Diseases When a disease spread from one person to the other, it is known as a communicable disease Most common are: Common Cold Ringworm Conjunctivitis (pink eye) Viral infections Nail, toe and foot infections

How does it spread Dirty Hands (under the finger nail and webs between fingers) Contaminated implements Cuts Open sores Pus Mouth (saliva) and nose discharge (mucus) Drinking cups Telephone receivers Towels

Viruses Parasitic submicroscopic particle that infects and resides in the cell of the host Capable of replicating (multiplying) Cause respiratory (breathing), and gastrointestinal (digestive) problems Examples…Measles, mumps, chicken pox, smallpox, rabies, hepatitis, polio, influenza (cold), HIV…causes AIDS

Blood borne Pathogens Disease-causing that is carried in the body by blood or body fluids Transmitted possibly through haircutting, chemical burns, shaving, nipping, facial treatments, waxing, tweezing, any kind of broken skin

Blood Pathogens Hepatitis- blood born virus causes diseases that can damages liver Easier to contract Present in all body fluids Can survive on the surface outside the body HIV- Human immunodeficiency syndrome AIDS- acquired immune deficiency-syndrome Can be unidentified for up to six months Body fluids, secretions
