Bacteria and Archaea Flashcards
Diplococci (pairs)
bacteria: Neisseria gonorrhoeae
disease: Gonorrhea
Streptococci (chains)
bacteria: Streptococcus pyogenes
disease: Strep throat
Staphylococci (grape-like cluster)
bacteria: Staphylococcus aureus
disease: boils
rod-shaped bacteria
Listeria monocytogenes and Haemophilus influenza
cholera
vibrio cholera (single polar flagellum)
Borreliaburgdoferi
Lyme disease
Borrelia hermsii
relapsing fever
Campylobacter (pairs)
diarrhea
Treponema pallidum
syphilis
Pleomorphic bacteria
CDW cell wall-deficient bacteria
mycopLAsma
pleomorphic bacteria (no cell wall)
resistant to antibiotics that inhibit cell wall synthesis
what is the best method for bacterial fixation
methanol fixation
acid-fast chain is used in the diagnosis of
Tuberculosis
acid-fast stain is used to diffrentiate between
Mycobacteria
acid-fast stain is used to diffrentiate between
Mycobacteria
acid-fast stain is used to differentiate between
Mycobacterium and any other bacterium
how can we test for bacteria motility
1- semisolid agar or stabbing method
motile organisms will grow away from the stab line
2- hanging-drop method
the size of colonies is determined by
the organism’s rate of growth (generation time)
Obligate aetobes
Mycobacteria
Microaerophilic aerobes
Neisseria gonorrhoeae and Campylobacter
facultative Anaerobes
staphylococci and streptococci
main elements (nutritional requirements) for all bacteria
C, H, O, S, P, N
Rickettsias
unique bacteria
gram-negative
All the diseases it causes involve production of rash
Chlamydias
unique bacteria
Gram-negative
obligate intracellular pathogens
Chlamydia trachomatis
Trachoma → causes blindness
Conjunctivitis (also eye disease)
Nongonococcal urethritis (NGU, STD)
Mycoplasma (M. pneumoniae)
atypical pneumonia
M. genitalium (mycoplasma)
NGU
human monocytic ehrlichiosis (HME) is caused by
Ehrlichia chaffeensis:
human granulocytic ehrlichiosis (HGE) is caused by
Anaplasma
example on oxygenic photosynthetic bacteria
cyanobacteria
