I had proteus mirabilis in my vagina not my bladder. therefore no uti, just bacteria in my vagina. how would my husband be tested for it and is it necessary? also what type of doctor would do testing?

Not typical: Proteus mirabilis is not a typical pathogen of vaginal infections. It is more typical of uti's, but you probably already know this. In terms of your husband, it is not considered an std and it is not associated with miscarriage. He could simply have a urine culture performed by a primary doctor if you are still concerned. Talk with your ob/gyn.
