Pathogenic

Infectious diseases are caused by prions, viruses, rickettsia, chlamydia, bacteria, pathogenic fungi and protozoa.

Towards the end of the 1990s, several Asian countries lived one of their worst health nightmares. A new, highly pathogenic, strain of Avian Influenza known as H5N1 killed hundreds of people. Over the next years, more than 9-million chickens were destroyed in an effort to stem the epidemic. Scientists believe the H5N1 virus was transmitted from wild birds to domestic poultry and pigs, which then passed it to humans. H5N1 is just the latest of various influenza strains that have killed up to 100 million people over the last century.

While the environment is teeming with bacteria and fungi, most are not pathogenic.
