Cells, Microbes & Viruses / Re: phagocytosis

Oke,

But what if there is not enough (IgA) to prevent virusses/ bacteria anymore. I was thinking about a product which has got specific IgA/IgG against bacteria which causes serious problems in the GI tract. This product you have to drink/eat so it has to pass the gastric juice. It's known that IgA could pass that part and IgG will mostly denature.
That's why I asked myself if IgA also could opsonize bacteria to enhance the phagocytosis.
I now know that it is possible against Bordetella pertussis infection. But this is reached by vaccination and that's not an option in this case.

Is opsonization which will help the phagocytosis, possible with IgA?

Cause in biologybooks there are only discriptions that IgG captures a bacterial cel (with their fab fragments). I know that IgG is more common in our body, so there's a bigger chance that there are antibodies specific to a bacteria that are IgG's.
