Arrange the following in order of pathogenicity: Gram + cocci, Gram + rods, Gram - cocci, Gram - rods
1. Gram + cocci
2. Gram - rods
3. Gram - cocci
4. Gram + rods
This genus of bacteria grows in chains of spherical cells.
Streptococcus
The __-hemolytic streptococci lyse RBCs
Beta
The __-hemolytic streptococci cause blood-containing media around the colony to turn green.
Alpha
Streptococci acquire energy by what mechanism?
fermentation, but most are oxygen-tolerant anaerobes
B-hemolytic strains of Streptococci are further divided into groups (A through T) based on their cell wall polysaccharides. Which group is the most important in human disease?
group A
This group of streptococcus is responsible for causing "strep throat".
group A
What is the most important pathogenic A-hemolytic streptococcus?
S. pneumoniae (bacterial pneumonia)
This genus of Gram + cocci looks like buckshot or bunches of grapes under the microscope.
Staphylococcus
What are the two main pathogenic species of Staphylococcus?
S. aureus and S. saprophyticus
What mechanism do Staphylococci use to obtain energy?
aerobic respiration
This enzyme, produced by S. aureus, clots plasma.
coagulase. Catalyzes the transformation of fibrinogen to fibrin.
Two major pathogenic species of Neisseria, a Gram - cocci.
gonococcus and meningococcus
What is the agent of diphtheria?
Corynebacterium diphtheriae, a Gram + rod
The only important pathogenic species of aerobic Bacillus, a Gram + rod.
B. anthracis
List three important strict anaerobes belonging to the genus Clostridium, a Gram + spore-forming rod
C. botulinum, C. tetani, C. perfringens
This species of Clostridium is responsible for antibiotic mediated pseudomembranous colitis. The antibiotics typically responsible for this are Clindamycin since it targets anaerobic bacteria, and penicillin family drugs.
C. difficile
Which genus of enteric bacteria causes typhoid fever and food poisoning?
Salmonella
Which genus of enteric bacteria causes bacillary dysentery?
Shigella
This species of enteric Gram - rods ferments lactose.
E. coli
In what 4 organs are steroids produced by the sER?
1) Testes
2) Ovaries
3) Adrenal cortex
4) Placenta
This genus and species of Gram - rods is responsible for cholera.
Vibrio cholerae
This Gram - rod is commonly implicated in gastritis, gastric ulcers, and gastric cancer.
Helicobacter pylori
This genus of fastidious Gram - rods causes pneumonia and meningitis.
Haemophilus
This genus of fastidious Gram - rods causes whooping cough.
Bordetella
This genus of fastidious Gram - rods causes brucellosis.
Brucella
This genus of fastidious Gram - rods causes tularemia.
Francisella
This genus of fastidious Gram - rods causes cat scratch fever.
Bartonella
This organism, a fastidious Gram - rod, causes legionnaires disease
Legionella pneumophila
These acid-fast bacteria include the tubercle bacillus and leprosy bacillus.
Mycobacteria tuberculosis and Mycobacteria leprae
This genus of spirochetes causes icterohemorrhagic fever.
Leptospira
This spirochete causes relapsing fever
Borellia recurrentis
This spirochete causes Lyme disease.
B. burgdorferi
This organism is the most common cause of the STD clamydial urethritis.
Clamydia trachomatis
This genus of parasites is responsible for typhus and RMSF.
Rickettsiae
This genus of bacteria lacks murein and requires sterols.
Mycoplasma
