|---|---|---|---|---|---|
| Cell Wall | Bacteria have two basic cell wall structures referred to as gram positive and gram negative.
🗑
|
||||
| Consists of a single cytoplasmic membrane surrounded by a highly cross-linked, thick layer of peptidoglycan. | gram=positive cell: other components besides the thick layer of peptidoglycan are various surface proteins
🗑
|
||||
| The thick layer of a gram-positive cell is made of | peptidoglycan
🗑
|
||||
| This cell's wall contains an inner cytoplasmic membrane, a thin layer of peptidoglycan, a periplasmic space and an outer membrane. | gram-negative
🗑
|
||||
| The outer membrane of this bacteria's cell wall is asymmetric and contains LPS (lipopolysaccharide, known as endotoxin. | gram-negative
🗑
|
||||
| Know and locate these structures within the bacteria cell | pili or fimbriae, flagella, capsules, and spores.
🗑
|
||||
| Has a singular cell wall | gram positive
🗑
|
||||
| Has an inner cellular and outer membrane, a thin layer of peptidoglycan, lightly crosslinked and pore proteins. | gram negative
🗑
|
||||
| has a thick layer of highly crosslinked peptidoglycan, teichoic acid, lipoteichoic acid and a single cellular membrane | gram-positive
🗑
|
||||
| Do not contain a nucleus | Bacteria
🗑
|
||||
| example from lab of an aerobic gram-positive Rods (spore former) | Bacillus anthracis (anthrax) and bacillus cereus
🗑
|
||||
| An example from Lab of an aerobic gram positive Rods (Non-spore former) | corynebacterium diphtheriae (diptheria) and Listeria monocytogenes(meningitis)
🗑
|
||||
| The gram-positive cocci encompass these three genera: | Staphylococcus, Streptococcus and Enterococcus
🗑
|
||||
| Food Poisoning Bacteria | Staphylococcus aureus (gram-positive cocci that form clusters)
🗑
|
||||
| Tenderness and pain around catheters and shunts, it's slime layer adheres to them | Staphylococcus epidermidis (normal skin flora usually transmitted through surgical placement of valves, catheters and shunts)
🗑
|
||||
| Gram-Negative Cocci | Neisseria gonorrhoeae
🗑
|
||||
| Silver Nitrate was put in newborns eyes because of this bacteria | Neisseria gonorrhoeae
🗑
|
||||
| The largest group of bacterial human pathogens | gram-negative rods
🗑
|
||||
| Pneumonia and meningitis | Haemophilus influenzae (example of gram-negative rod)
🗑
|
||||
| Bordetella pertussis | Whooping cough (example of gram negative rod)
🗑
|
||||
| ?Cannot grow in the presence of atmospheric oxygen | anaerobes
🗑
|
||||
| Anaerobes form ____ if they are gram positive | spores
🗑
|
||||
| Example of anaerobe, spore formation, gram pos rod, associated with deep puncture wounds, spores contaminating soil | Tetanus

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
