When antibodies bind to the epitopes of an antigen(bacteria) via antigen receptors, the antibodies present the bacteria to a macrophages in a form that they recognize the foreign substance and engulf them. This antibody-antigen "team work" is also known as opsonization
Unicellular infectious agents are prokaryotes, eukaryotes, bacteria, and protoza.
fungi and protozoa and bacteria
No. You also have bacteria, fungi, etc.
Prions, Viruses, Bacteria, Fungi, and Animal Parasites.
The term you are looking for is "fomite." Fomites are objects or materials that can carry and transmit infectious agents, such as viruses or bacteria, from one person to another.
It protects against infectious agents such as fungi,bacteria and viruses.
Prions are the smallest known infectious agents.
Various infectious agents can cause upper respiratory infections, such as viruses (e.g., rhinovirus, influenza virus) and bacteria (e.g., Streptococcus pneumoniae, Haemophilus influenzae). The most common cause of URIs are viruses.
Mucus is found in the respiratory system of humans. The function of mucus is to protect the body from infectious agents such as viruses and bacteria.
As the list of pathologies and infectious agents are extensive, a related link is shown below.Once the web page is open, click on Figure 10.3. A table is displayed showing the main infectious agents and the pathologies they cause.
No, a macrophage is not a virus; it is a type of immune cell found in the body that plays a crucial role in the immune response by engulfing and digesting pathogens, such as bacteria and viruses. Macrophages are part of the body's defense system, while viruses are microscopic infectious agents that require a host cell to replicate and can cause disease. In essence, macrophages help protect against viruses and other pathogens rather than being one themselves.
Viruses are the only non-biological infectious agents; all otheres are forms of pathogen, which are bacteria.
