contact w/infected birds

34
Q

C trachomatis

A

infects eye and degrades cornea, fatal.

35
Q

Mycoplasmas

A

smallest free living organisms. Do not have cell wall, do not produce there own sterols.
Mycoplasma pneumoniae- causes primary atypical pneumonia.
Penicillin is NOT effective.

36
Q

Streptococcus pyogenes

A

gram positive cocci.

Causes scarlet and rheumatic fever, endocarditis, pneumonia, pharyngitis, necrotizing fascitis

37
Q

Staphylococcus

A

gram positive cocci, catalase positive.
S. epidermis- nonpath
S.aureus- causes impetigo, osteomylitis, toxic shock, food poisoning.

38
Q

A

oxygenic photosynthetic bacteria…Red Sea

46
Q

Prochlorophyta

A

aka picoplankton Along with cyanobacteria a type of oxygenic photosynthetic bacteria.
Contain chlorophyll a and b, do not have phycobilins which is why they appear green and not blue green.
Have thylakoids with double membranes (cyano-single)

47
Q

Chemolithotrophic Aerobic Bacteria

A

Nitrifiers, colorless S bacteria, obligate hydrogen bacteria, Fe/Mn oxidizers, magnetic bacteria.

48
Q

Nitrifiers

A

These bacteria oxidize ammonia to nitrite and nitrite to nitrate.
Ammonia to nitrite, nitrosfying bacteria, Nitrosomonas, Nitrosospira, Nitrosococcus, Nitrosolobus.
Nitrifying bacteria, nitrite oxidized into nitrate, Nitrobacter, Nitrospina, Nitrococcus.

49
