Activity: Book Work pg. 467-473 The two Kingdoms of bacteria are known as and. One reason Archaebacteria is placed into a separate kingdom is because its cell walls do not have, which is a protein carbohydrate compound found in the cell walls of Eubacteria. Archaebacteria were first discovered in extreme environments, such as,, and. The three phylogenetic groups of archaebacteria are,, and. Methanogens found in anaerobic conditions such as at the bottom of and, where they convert H2 and CO2 into. Extreme halphiles are archaebacteria, and live in environments with very high salt concentrations such as the Dead Sea. Thermoacidophiles live in extremely environments that have high temperatures, such as volcanic or hydrothermal vents. Eubacteria account for most bacteria and have three basic shapes. Eubacteria that are rod shaped are called. Eubacteria that are sphere shaped are called. Eubacteria that are spiral shaped are called. When cocci occur in chains they are called, and when cocci occur in grape like clusters they are called. Eubacteria are divided into 12 different phyla. Some basic phyla of bacteria are (table 24-1),,, and. Phylum cyanobacteria were once known as blue-green algae, but do not have a membrane bound nucleus. To acquire energy cyanobacteria perform. Phylum spirochetes are shaped heterotrophic bacteria and are known to cause the STD syphilis. Phylum Gram positive bacteria are a main producer of, which inhibit growth or kill microscopic organisms. Phylum proteobacteria is the one of the largest and most diverse bacteria kingdoms and include bacteria and. Class Review Questions: 1.

Gram positive bacteria stain a. blue b. pink c. red d. purple Bacteria and Disease Type of Disease Areas Affected Mode of Transmission Botulism nerves Improper preserved foods Cholera intestines Contaminated water Tooth Decay teeth Bacteria in mouth Gonorrhea Urethra/ fal.tubes Sexual contact Lyme Disease Skin, joints, heart Tick bite Rocky Mountain Spotted Fever Blood, skin Tick bite Salmonella intestines Contaminated food
Strep throat Respiratory tract Sneezing/coughing Tetanus nerves Contaminated wounds Tuberculosis Lungs, bones, etc coughing Ways Bacteria Cause Disease Activity: Book Work: pg. 478-479 The scientific study of disease is called. Bacteria that causes disease is known as. Some bacteria cause disease by producing poisons called toxins. are toxins produced by Gram-positive bacteria and are secreted into the surrounding environment. Toxins that are associated with Gram-negative bacteria and are not released from the bacteria until it dies are known as. Class Review Questions 1. One bacterial disease that is transmitted by contaminated drinking water is a. Lyme disease b. Gonorrhea c. Tuberculosis d. Cholera 2. A poison that is released from the outer membrane of dead Gram negative bacteria is called a. a pathogen b. an exotoxin c. an endotoxin d. a broad-spectrum toxin 3. Which of the following is not a way that bacteria cause disease in humans? a. Destroying body tissues b. Conjugating human cells c. Damaging blood vessels d. Dissolving blood clots 4. Bacteria that cause disease are known as a. Pathology
b. Endotoxins c. Pathogens d. Exotoxins 5. A poison that is produced by gram positive bacteria while the bacteria are still alive is known as a. Pathology b. Endotoxin c. Pathogens d.
