A method of controlling, in a warm-blooded animal, an infectious microorganism expressing a chorionic gonadotropin-like growth-regulating protein comprises modulating the activity of the protein by administering to the warm-blooded animal an effective amount of an antibody capable of inhibiting the activity of the protein, the chorionic gonadotropin-like growth-regulating protein itself such that the animal develops a neutralizing immune response, or peptides that block the receptors of the chorionic gonadotropin-like growth-regulating protein in the infectious microorganism. Candida albicans is one such microorganism that can be controlled by delivering an antibody against the growth-regulating protein, CaCGLP. Mycobacteria can also be controlled by this method. A method of inhibiting transition of Candida albicans blastospores in vitro by contacting the blastospores with an antibody against CaCGLP is also disclosed. A method of inhibiting growth of mycobacteria in vitro comprises contacting the mycobacteria with an antibody against an endogenous chorionic gonadotropin-like growth-regulating protein. In vitro growth of microorganisms can also be stimulated by contacting the microorganism with a chorionic gonadotropin-like growth-regulating protein.

Control of infectious microorganisms by modulation of chorionic

A protein isolated from Pseudomonas maltophilia is found to possess an exposed, immunologically accessible protein which binds to the FC region of several species of immunoglobulins. The protein is found to bind both IgG and IgA immunoglobulins and is found to have an effective molecular weight of approximately 30,000 daltons. The protein is found to be useful in isolation of IgA immunoglobulins from biological mixtures. The protein makes IgA immunoglobulins available for further analytical techniques, including identifying bacteria which contain IgA binding proteins. Because of the increased availability of IgA immunoglobulins, it is possible to diagnosis and treat IgA-related diseases and their sources.
