I go with BB...............I think this is a strong TH2 response in lepromatous leprosy..........high no. of bacteria produces nerve damage which may be the thick tender cord............i'm not sure though.............

I will go with B, TH2 response. Useless antibodies of Lepromatous Leprosy. But what's the tender neck cord business?

Correct Answer b

the ans is bacteria itself >>>>>>strong th2 response indicates lepromatous leprosy as it shuts down th1 response so no intracellular killing by th1 response..
@subbi>>>thanks for explanation
@dockhi>>>tender cord in neck indicates NEURITIS
