Ans:
D) S. pyogenes
A) Salmonella
Example: Invasins are the extracellular protein that facilitates invasion into the host cells. Streptokinase, hyaluronidase, streptolysins, colagenase etc. are the example of Invasins that are produced by the pathogenic bacteria. Streptolysin is the invasins that is produced by the Streptococcus pyogenes which disrupts phagocytes membrane and causes releases of lysosomal granules. Salmonella also produces Invasins. Neisseria and Trypanosoma doesn't produce Invasins.
This bacterium produces invasins A)Salmonella B) Neisseria C) Trypanosoma D) S. pyogenes

Bacillus e. Methanobacterium helt
Neisseria has acquired resistance to penicillin. How can it achieve this? A) Neisseria bacteria are dormant and penicillin works on active cells B) Neisseria bacteria are too small for penicillin to kill C) Neisseria bacteria are constantly changing for penicillin to work D) Neisseria bacteria produces proteins to make penicillin ineffective
