摘要:

AbstractThis review is directed toward the study of the physiology and biochemistry of parasitic fungi on insects and stresses the usefulness and utility of these organisms from the standpoint of applied research and biotechnology. The review covers the principal contributions made by investigators toward elucidation of the infective mechanisms of the entomogenous fungi, and the various biochemical attributes of these organisms. The interplay of the various enzymes and associated biochemical substances which are involved in the infective process is discussed as well as the important studies of the peculiar physiology frequently associated with these microorganisms.

摘要:

AbstractEnterococci are widely distributed in nature. They gain entry into milk and milk products through the water supply, equipment, and insanitary and unhygienic conditions of production and handling. They have been incriminated as direct or indirect agents of disease. The evidence concerning their involvement is only circumstantial. These reports are also disputed as the disease symptoms have not been experimentally induced in animal models. However, there is sufficient evidence to indicate that prolific growth of enterococci in foods may lead to formation of clinically significant levels of pressor amines. These amines are very thermostable and therefore remain active even after heat processing, which eliminates all viable streptococci. These pressor amines may be involved in the onset of migraine attacks and produce hypersensitive crises in psychiatric patients who are being treated with monoamine oxidase inhibitors for depression.

摘要:

AbstractA new prophylactic and therapeutic antimicrobial strategy based on a specific physiological target that is effectively used by killer yeasts in their natural ecological competition is theorized. The natural system exploited is the yeast killer phenomenon previously adopted as an epidemiological marker for intraspecific differentiation of opportunistic yeasts, hyphomycetes, and bacteria. Pathogenic microorganisms(Candida albicans)may be susceptible to the activity of yeast killer toxins due to the presence of specific cell wall receptors. On the basis of the idiotypic network, we report that antiidiotypic antibodies, produced against a monoclonal antibody bearing the receptor-like idiotype, arein vivoprotecting animals immunized through idiotypic vaccination andin vitromimicking the antimicrobial activity of yeast killer toxins, thus acting as antibiotics.
