Vehicles are inanimate materials that can have pathogens. Examples food, water, fluids, air

gram negative, lipids,
they are released when a cell lyses, as well as during multiplication
-
-
a pathogen when introduced to a host, can survive, reproduce and overpower the host immune system and can cause an...
once infected, the pathogen can use the host machinery to spread and be transmitted to other hosts
-
a person could come into physical contact with a reservoir, which is an environmental location in which the pathogen resides, and acquire the pathogen.
Direct transmission deals with physical contact with the pathogen. Examples include kissing, touching, talking (via droplet) , sexual contact.
Indirect transmission usually involves an inanimate objects, like door handles, bedding, utensils. Examples also include aerosols, tiny particles of which can linger for some time, as well as air.

-
this type of transmission is through living organisms, usually insects, household pets, or wild animals

gram positive and gram negative, these are proteins that are released from the pathogens into their surroundings in the host. Cytolytic exotoxins degrade the cytoplasmic membrane causing cell lysis and death. Super-antigens cause T-cells to over-express eventually resulting in host organ failures. AB toxins are membrane-disrupting, and bind to specific host sites.
the human body contains millions of microorganisms, creating the human microbiome
this is the functional the collection of microbes in a dead body, after a human dies
once a human dies, the human microbiome becomes a..
includes the gut microbiome, which impacts many parts of the human body including, digestion, mood, as well as immune response and protection against pathogens
gut microbiomes typically contain probiotics which are live organisms that benefit the health of a host organism
humans and probiotics share a mutualistic relationship, where both organisms benefit. Different probiotics help human health, while humans provide probiotics with protection as well as nutrients

the relationship between humans and viruses is oftentimes a parasitic relationship, where the virus cause damage to the human host, and the human host provides protection and machinery for the virus
-
bacteriophages infect a bacteria by injecting their genetic material into a bacteria, using its machinery to make more copies.

-
lysogenic cycle is where the virus integrates into the host genome and replicates using the host machinery without destroying the cell
