22 f plasmid is a conjugative plasmid also called as f factor that can integrate itself into the bacterial chromosome by genetic recombination during conjugation.

43.
which is correct ...
B lymphocytes recognizeantigen on APC in context of HLA D molecule.
HLA DR belongs to HLA class 2 antigen of MHC.It is expressed on B lymphocytes , monocytes,macrophages, activated T lymphocyts.


56
coagulase production in staphylococcus aureus converts fibrinogin to fibrin.coagulase is tightly bound to s.aureus and coates its surface with fibrin when in contact with blood and protect the bacteria from phagocytosis and increases its virulence.
hence i feel the answer is coagulase helps establish cellulitis and abscess

6.each is reguired for the viral antigen recog by CD4 t helper ells except..
1.viral replication in the host (only sometimes invitro)


8. primary site for ghons complex is sub plural parenchyma and hilar l nodes.
ghoncomplex is the combination of ghon focus(initial infec by bacillus) and lymphatic leison.Bacilli in macrophages drain out from the area towards the affected lung lymph nodes and form caseous granuloma.


9. bacterial lippoplysaccharides contail all except--- techioc acid
lipopolysaccharide complex in outer cell membrane of gram-ve bac is also known as endotoxin.Its toxicity is associated with lipid A,its immunogenicity is associated with core polysaccharides and inflammatory responses by cell wall o antigen


30. unique aspect of cariogenic stains of strepto mutans from other acidogenis organisms is....extracellular polysaccharide
s.mutans have receptors to adhere to the tooth surface.it utilises sucrose to produce sticky extracellular dextran based polysaccharide that help in formation of plaque

47
necrosis characteristic of pyogenic infections is liquefactive .
pyogenic infection is produced by accumulation of dead leukocytes and infectious agents called pus and liquefaction necrosis results from cellular destruction of hydrolytic enzymes like leukocytic enzymes and form suppuration.

56.prevotella intermedia detectable in oral cavity immediately after the PDl diseases appear
Butthe other species prevotella nigrescence is found both in healthy and diseased individuals.
correct me if iam wrong
