my finals are in 3.5 weeks' time.

brucella species causes abortion in several cattle species and commonly in poorer developing nations. not to be confused with:

bordetella pertussis, or parapertussis, both of which cause whooping cough, and are immunised for at birth as part of the DPT trivalent vaccine. as with most activated vaccines, it may cause fever and rash at site of injections, which may be mistaken for:

bartonella species
which causes catbite fever and bacillary peliosis in the immunocompromised. which sounds very much like

borrellia recurrentis (which causes epidemic relapsing fever and is spread by the body louse), duttoni (congenital relapsing fever) and burgdorferi (lyme disease, spread by hard ticks). common in the homeless or in times of social upheaval, when personal hygiene is generally poor.

burkholderia pseudomallei causes meliodosis, another common disease of the immunocompromised. closely related to burkholderia mallei, which doesn't infect humans at all. these are endemic in singapore and common in diabetes mellitus patients and construction workers. another common disease among construction workers is (i just like the names very very much...)

orientalis tsutsugamushi, which is spread by the chigger, a rat flea, and is responsible for scrub typhus.

of course all organisms are identified by different means. brucella, a gram neg rod, grows well on salty blood agar, bartonella is a variable-staining but often gram negative rod, borrellia is unculturable on normal agar, burkholderia grows as large wrinkled grey colonies on enriched blood agar, and o tsutsugamushi doesn't stain at all. hoho.

this is 6 bacteria, which is maybe about 5% of 128 bacteria, which is 1/4 of 1 module. 1 module is equivalent to 1/6 of our course, this year. there are effectively 4 years of teaching.

10-90-90-10 rule: doctors only use 10% of what they're taught, 90% of the time. but 90% of the justification for our salaries is because of that last 10%...

i think i prefer the UN generals to bacteria. there are no anti-UN drugs to remember.. (maybe just one, bolton. haha)
