pls answer these questions,thanks

A patient who has minimal resistance to a gonococcal infection MOST probably has

1. Leukocytosis
2. agammaglobulinemia
3. an eosinophil deficiency
4. deficiency in cell mediated immunity
5. deficiency in complement factors C6 , C7 and C8 (ans)

Coagulase production by Staphylococcus aureus is important in pathogenicity because it

1. helps to establish the typical abscess lesion
2. helps to establish the typhical cellulitis lesion
3. allows the organisms to adhere tightly to tissue
4. Provides a polysaccharide capsule to inhibit phagocytosis
5. non specifically binds to the Fc portionof lgG molecules. (ans.)


Which of the following causes the rash associated with scarlet fever?

1. Pyrogenic exotoxin
2. Hyaluronidase
3. Streptolysin O (ans.)
4. Streptolysin S


The distolingual cusp of a maxillary second molar in protrusive movement has potential to oppose which morphologic entity of which mandibular molar ?


Morphologic entity Mandibular Molar

1. Mesial portion third
2. Central fossa second (ans)
3. mesial marginal ridge second
4. distal transverse ridge second



The H occlusal groove pattern is characteristic of which premolar?

1. Maxillary first
2. Mandibular first
3. Mandibular second with two cusps (ans)
4. Mandibular second with three cusps

I think that's the answer
Correct me if I'm wrong ~🙂

2. helps to establish the typhical cellulitis lesion
3. allows the organisms to adhere tightly to tissue
4. Provides a polysaccharide capsule to inhibit phagocytosis (this is the most likely ans, cuz coagulase walls off the infection site, thus preventing phagocytosis, i'm confused wid this Polysacc. capsule)
5. non specifically binds to the Fc portionof lgG molecules.


Which of the following causes the rash associated with scarlet fever?

1. Pyrogenic exotoxin (also called the erythrogenic toxin)
2. Hyaluronidase
3. Streptolysin O
4. Streptolysin S


The distolingual cusp of a maxillary second molar in protrusive movement has potential to oppose which morphologic entity of which mandibular molar ?


Morphologic entity Mandibular Molar

1. Mesial portion third
2. Central fossa second
3. mesial marginal ridge second
4. distal transverse ridge second (cuz as the mandible protrudes, the DL cusp will come out of the central fossa and potentially will contact the DTR of 2nd molar, although i have some doubts about option 1 too)



The H occlusal groove pattern is characteristic of which premolar?

1. Maxillary first
2. Mandibular first
3. Mandibular second with two cusps
4. Mandibular second with three cusps


let me know if i am wrong... thanx 🙂

I'm not too sure about the answers but giving them with my explanations, correct me if im wrong.

patient who has minimal resistance to a gonococcal infection MOST probably has

1. Leukocytosis
2. agammaglobulinemia (ans) since humoral immunity is active against encapsulated organisms
3. an eosinophil deficiency
4. deficiency in cell mediated immunity

Coagulase production by Staphylococcus aureus is important in pathogenicity because it

1. helps to establish the typical abscess lesion(ans) the reason given before is correct, coagulase walls of infection, and abscess is a localized infection.
2. helps to establish the typhical cellulitis lesion
3. allows the organisms to adhere tightly to tissue
4. Provides a polysaccharide capsule to inhibit phagocytosis
5. non specifically binds to the Fc portionof lgG molecules
5. deficiency in complement factors C6 , C7 and C8

next, pyrogenic toxin is correct
