Explanation / Answer

34) Infection of urinary bladdr is called as cystitis. Infection of kidney is called as pyelonephritis and infection of ureter is called as ureteritis. So, the correct answer here is option (a) cystitis.

35) Coagulase is an enzyme that is produced by various microorganisms. Staphylococcus aureus produces two types of coagulase: bound and free. Bound coagulase is present in the bacterial cell wall and acts on fibrinogen. Free coagulase is involved in the activation of plasma coagulase-reacting factor (CRP) to from a coagulase-CRP complex which in turn reacts with fibrinogen to produce the fibrin clot resulting in blood clotting. So, the correct answer for this question is option (c) coagulase is an enzyme used by Staphylococcus aureus to clot plasma.
