Could you medical students answer these questions?
I would appreciate it

The requirement for an insect vector in the transmission of human disease is a common characteristics if all the infectious agents included in the genus
a Bedsonia
b Brucella
c Treponema
d Rickettsia
e Mycoplasma

The most common clinical sign of the kidney disease is
a Hypertension
b Poly urea
c polydipsia
d No urine output

The most smallest mutation in DNA is
a Base change
b Translocation of the segment
c Loss of segment

The "most smallest mutation" in DNA is
a Base change
b Translocation of the segment
c Loss of segment

I'd go with a) base change.

Thanks JayZee for your reply

The most common clinical sign of the kidney disease is
a Hypertension
b Poly urea
c polydipsia
d No urine output

I think I'll go for A, because of increased renin production (seen in renal cell carcinoma, decreased renal perfusion, and renal obstruction in the case of calculi)

Rickettsia


The most common clinical sign of the kidney disease is
a Hypertension
b Poly urea
c polydipsia
d No urine output

in hospital is oliguria (acute tubular necrosis, renal papillary necrosis, kidney failure).

The most smallest mutation in DNA is
a Base change
b Translocation of the segment
c Loss of segment

base change

coxiella is included in rickettsia but is not transmitted by an insect vector ... the OP asked about ALL the infectious agents in the genus ...

thanks dara
Anyone have any suggestions about the second question (clinical sign of the kidney disease )?
thanks

The question about the insect vector is VERY badly written.
The answer is Rickettsia, tho, for the following reason:
They ask about the GENUS, which essentially means "all the bugs with rickettsia as their first name." Coxiella is not insect-borne, and yes, it is in the Rickettsia FAMILY (called "rickettsiaciaeaeae-something"), but it is not in the genus.
Now, the main reason why this q. is bad is they ask about INSECT vector. Rickettsia genus bugs are carried by ARTHROPODS, not just insects. So you have lice and fleas, which are insects (typhus, etc.), but then you also have ticks (as with rocky mountain spotted fever), which are not.
But by elimination, they are probably asking for rickettsia (btw, i looked up bedsonia...it is the older name for chlamydia).

i stand corrected!

i looked it up, and actually coxiella is in its own family now, coxiellaceae ... although i suppose that must be a rather new development, as it hasn't been included in first aid yet. 🙂
