Bacteria
Human pathogens are classified based on their ability to cause disease in humans. They can be classified as bacteria, viruses, fungi, parasites, or prions, depending on their biological characteristics and the type of infection they cause. Additionally, they may be further categorized into subtypes based on their specific properties and modes of transmission.
That will vary from disease to disease and organ to organ.
Algae produce there own food as they have chlorophyll. So they usually do not produce disease. But it is interesting to note that the malaria parasite, which affect hundreds of million people each year, worldwide, has evolved from algae most probably.
Moraxella bovis is not airborne - it is spread through flies or by direct contact between animals.Moraxella catarrhalis might be a commensal of the human respiratory tract (meaning it is naturally found there). It is believed that it should not cause disease unless there are other underlying factors (such as immunocompromise).Airborne transmission, if it occured, would therefore not be expected to cause disease.
human to human transmission of disease is through air, water,or body contact of the diseased person. when a person is diseased and sneeze or cough in pen air the germs of disease gets into the air and transmit to other people.similarly water and body contact of diseased person will cause transmission
Pathogens can cause disease in the human body by invading tissues, releasing toxins, and triggering an immune response that can damage healthy cells and tissues.
Protists and helminths can cause an disease in an human body. One of the best known diseases caused by protists in the genus Plasmodium is malaria.
Bacteria
Horizontal transmission is the only form of transmission that can be transmitted from and infected human to ansusceptible.i hope that answer you question
They are the leading producers of parasites.
Streptococcus

Yes, people do have microbes living in their mouths (particularly those which cause tooth decay) and those can cause a disease if they get into the blood by way of a bite.
Pathogenic bacteria are bacteria that cause human illness. Of all species of bacteria in the world, only a small percentage actually cause human disease.
