Open in App
Solution
The correct option is A Acute
The three stages of the infection are acute, sub-acute and chronic. In the acute stage, there are less number of antibodies produced. IgM is the membrane antibody which is released during the acute stage of infection. In the sub-acute stage, there is an increase in the release of IgA and then subsequently IgG in the chronic stage. So, from the titre of IgM, the acute stage of brucellosis can be diagnosed.Thus, the correct answer is option A.
