Following is true about C reactive protein -: (A) Detected by precipitation with cabohydrate, (B) Raised in acute pneumococcal infection, (C) It is antibody, (D) Detected by agglutination test
Answer is B. S. pneumoniae contain a nucleoprotein deep inside the cell and a somatic C antigen. An abnormal beta globulin that precipitates with the somatic C antigen of S. pneumoniae is called CRP. It appears in acute-phase of pneumonia but disappears during convalescence. ref:Textbook of microbiology, Ananthanarayan an, Paniker. Page no.: 222
