Abstract: A light source for emitting light, a light conduit in electromagnetic communication with the light source for communicating light from the light source to the area of interest in three dimensions, and a controller combined to the light source for controlling the intensity of the light emitted to the area of interest.

Abstract: Protection of ruminants against bacterial pneumonia caused by Pasteurella haemolytica has been achieved with a subunit vaccine. The vaccine contains two principle components; capsular polysaccharide of P. haemolytica and a synthetic adjuvant, muramyl dipeptide. This vaccine prevented bacterial infection of the lungs of vaccinated animals upon challenge with P. haemolygica. In contrast, animals that were not vaccinated or animals that were vaccinated with only capsular polysaccharide alone had severe lesions and high concentrations of P. haemolytica in the lung.
