A pathogen is a disease causing organism. There are many types of pathogenic organisms. Bacterial pathogens include such organisms as staphlococcus, which causes a staph infection and  streptococcus, which causes strep throat.  Tuberculosis is caused by bacteria in the lungs. Syphillis and gonorrohea are two sexually transmitted diseases caused by bacteria. Bacteria are treated with antibiotics. Viruses can be pathogens, notably the H.I.V. virus which can lead to A.I.D.S., the herpes family of viruses, which can lead to cold sores, chicken pox and shingles, the influenza virus, which causes flu and the common cold virus(of which there are many types). Fungi can be pathogens notably athlete's foot fungus and ring worm, which can cause fungal infections of the feet and skin and yeast which can produce a yeast infection inside the vagina.  Organisms called Protists can be pathogens, as is the case with Malaria. After the Anopheles mosquito bites a victim, it injects the protist pathogen into the victim's bloodstream, where it attacks the red blood cells. Worms can be pathogens, for example, pinworms, tapeworms, roundworms. They cause illness inside the host, where they feed and multiply.
