What are the important types of micro-organisms to consider?
A number of different organisms can infect cats – protozoa such as Toxoplasma gondii and Giardia, yeasts and fungi, bacteria, and viruses. Of these, viruses are generally considered to be the most important pathogens of cats. The viruses include the cat flu viruses feline herpesvirus (FHV) and feline calicivirus (FCV), feline parvovirus (FPV) the cause of enteritis and panleukopenia, feline leukaemia virus (FeLV), feline immunodeficiency virus (FIV) and feline coronavirus, the cause of feline infectious peritonitis (FIP). FPV and FCV are the two viruses which are most resistant to disinfectants, and are two of the most infectious, so a disinfectant that is effective against these two viruses is desirable.
