As an immune response to antigen: Salmonella typhimurium, heterogenous populations of memory B cells retain which antibody isotype linked with BCR (B cell receptor) on cell surface?

As an immune response to antigen: Salmonella typhimurium, heterogenous populations of memory B cells retain which antibody isotype linked with BCR (B cell receptor) on cell surface? Correct Answer IgM BCR

Immune responses to complex antigens like Salmonella typhimurium can develop independently of GC formation in follicles and extrafollicular sites and this response is also accompanied by CSR and SHM-mediated immune maturation. The heterogeneous populations of memory B cells are possibly generated in as well as outside GCs and may retain IgM BCR on their cell surface.
