Disclosed are safe, simple and effective broad-spectrum treatments for halitosis and other microbial infections of the nondental upper respiratory tract useful to treat bacterial and other microorganism species, including anaerobic bacteria. Electromagnetic radiative energy including visible, and optionally, thermal, RF and/or microwave wavelengths, is topically applied to internal surfaces of the upper respiratory tract to destroy or incapacitate superficial microorganisms without the use of antibiotics. One useful apparatus is a handheld energy applicator having a light output head suitable for treating the back of the tongue and the tonsils and which may be interchangeably provided with extensions to reach the sinuses. The energy applicator can be supported and guided by a mounting device held between the subject's teeth, if desired. Useful embodiments of the invention include preparative treatment of the target surfaces with a photosensitizing agent such as an oxidizing agent or a complementary stain. Optionally a pre-treament procedure may be employed to remove detritus and microfloral overgrowths that may mask more deeply resident target microorganisms. Novel treatments include treatment of halitosis by destruction of bacterial species associated with halitosis, such as Atopobium parvulum, by application of non-ionizing radiative energy to the tonsils and the back of the tongue. Another embodiment comprises a candy bar incorporating a halitosis treatment lamp disposed within the candy.

Anaerobic bacteria are incorporated in a feed such that they provide a benefit to the consuming animal. Anaerobic bacteria can be viable and colonize the gut to provide this benefit by displacing harmful bacteria, secreting a particular agent (e.g., enzyme, antibiotic or bioactive compound), binding or sequestering harmful organisms or compounds, or providing a beneficial physical effect. Anaerobic bacteria can also be added n a non-viable form wherein the added bacteria provide a benefit to the consuming organism by delivering preformed compounds such as enzymes, bioactive agents, or polymers. Recombinant anaerobes can be utilized for any of the above purposes. Feeds can contain naked bacteria, spores, treated bacteria such as encapsulated, coated or freeze dried bacteria, in order to maintain either viability or stability of the active function.
