Candida albicans is a dimorphic fungus, i.e. it can take two forms.
I found it by google search.

 

[docsmiley]

hi..
yes..candida is right, butthe answer bank says epitrychomatis
anyone for the rest of the questions..these r latest questions...

 

[docsmiley]

sorry...
epidermatophytes...

answer to 1st ques is s saprophyticus
2nd is mitral valve(not sure)
3rd is candida

correct me if i am wrong

------------------------------------------------------
articular surface of adult mandibular condyle is covered by:

-------------------------------------------------------
epidemic of HIV-related disease bears major responsibility for the resurgence of which respiratory pathogen?
-strep pneumonia

to be integrated into the host genome, RNA oncogenic virus my possess:

-RNA ............... DNA ............
----------------------------------------------------------

one identifying morphologic characteristic of Candida albicans is :
-chlamydospores
-blastospores

(What are these things?!!!😕)
------------------------------------------------------------

aspiration can cause all of these EXCEPT:

-pneumonia
-pneumothorax
-lung abscess
-atelectasis

is that correct? ( I dont know the answer.)

--------------------------------------------------------------
Action potential initiated at midpoint along the axon will:

ans is collagen connective tisue...since tmj does not hav hyaline cartilage..
it has dense fibrocartilage.

wat is the method of gene transfer in bacteria that is least prone to dnase activity and does not need cell to cell contact..
1.transformation
2.conjugation
3.transduction..
pls explain ..also..

 

[dent_mangalore]

3.transduction..

definitely not conjugation as it requires cell to cell contact.....it's the "bacterial sex"
transformation is uptake of naked DNA so it is dnase susceptible
transduction however involves viral phage and is therefore dnase resistant and also does not require cell to cell contact

hey thanx..dent mangalore..
one more..
which type of shock is assoc with severe trauma and causes peripheral reactive vasodilation .
1.hypovolemic.
2.septic.
3.neurogenic.
4.cardiogenic.
5.anaphylactic.
pls explain also...

1.hypovolemic.
2.septic.
3.neurogenic.🙂
4.cardiogenic.
5.anaphylactic.
pls explain also...

3. Neurogenic shock-It is caused by trauma to the spinal cord resulting in the sudden loss of autonomic and motor reflexes below the injury level. Without stimulation by sympathetic nervous system the vessel walls relax uncontrolled, resulting in a sudden decrease in peripheral vascular resistance, leading to vasodilation and hypotension.

Thanks a lot for your answers.

which of the following nerves is the most likely to become injured in fractures of the mid humeral shaft?

-ulnar
-radial
-median
-axillary
are you sure about this? I thought it should be median b/c of its position in mid humeral?
------------------------------------------------------
articular surface of adult mandibular condyle is covered by:

-synovial memberane
-hyaline cartilage
-perichondrium
-collageneous connective tissue

I was thinking about the last choice. is condyle kind of synovial joint?

you are right. Thanks. Pili connects the bacterium to another of its species, or to another bacterium of a different species,for bacterial conjugation.
