F10 is manufactured in South Africa for Biocare Company in the UK. It is basically a surface active quaternary ammonia solution with both polyaminopropyl and polyhexamethylene biguanide additives. The quaternary ammonia is for artificial surface disinfection and the biguanides are for tissue and wound disinfection. It was originally developed as a hard surface, skin, and wound disinfectant, but has recently been pushed for use in an aerosol fogger application for elimination of airborn bacteria and viruses. My understanding is that it is not being used to directly treat respiratory infections in the animal itself, but is being used to disinfect the air in the holding rooms to avoid airborn transmission of the causative bacteria or virus. With respiratory infections, therapy with systemic antibiotics is still used concurrently with the F10 air treatment. It makes sense to not directly treat with F10 inhalation because the main ingredient, quaternary ammonia, is most definitely irritating to lung tissue in significant concentrations. However, its main use is still for the disinfection of table tops, cages, skin, and wounds.
