A pathogen that must live in or on a host to survive is known as an obligate parasite. These organisms rely entirely on their host for nutrients and reproduction, often causing harm in the process. Examples include certain bacteria, viruses, and protozoa that cannot complete their life cycle outside of a host organism. Obligate parasites can lead to various diseases in their hosts, showcasing their dependence on living hosts for survival.

Which pathogen MUST live in or on a host to survive?
A pathogen that must live in or on a host to survive is known as an obligate parasite. Examples include viruses, certain bacteria, and protozoa that rely entirely on host organisms for nutrients and replication. Unlike opportunistic pathogens, obligate parasites cannot complete their life cycle without a host, making them entirely dependent on their hosts for survival.
Effective antibiotics must be inhibitory to the intended target pathogen while not significantly harmful to the host This is referred to as?
Selective toxicity
What is the difference between a primary and an opportunistic pathogen?
Primary Pathogens are the microorganisms that cause diseases in healthy individual. Opportunistic Pathogens are the microorganisms that are ordinarily in contact with the host and cause disease when the host's resistance is low.
Are toxins virulence factors?
No. For something to be virulent it must be alive. Virulence usually refers to pathogens, like bacteria, viruses, and yeasts. But, pathogens, themselves, can create toxins by their metabolic activity. Still, however, the toxin itself wouldn't have the property of being virulent, only the "bug" would be.
What must a vaccination contain to make it effective in producing immunity?
A vaccination must contain either a weakened or inactivated form of the disease-causing pathogen, or specific pieces of the pathogen such as proteins or genetic material. This prompts the body's immune system to recognize and remember the pathogen, allowing it to quickly mount a response if the person is exposed to the actual pathogen in the future.

What does an aerobic pathogen need to survive?
An aerobic pathogen needs oxygen to survive, as it relies on aerobic respiration to produce energy for its cellular processes. It also requires a source of nutrients, a suitable temperature, and an appropriate pH level to grow and multiply within a host.
What type of host must be available and capable of being infected by a pathogen in order for infection to take place?
For an infection to occur, a susceptible host must be present, meaning that the host's immune system is either compromised or not fully equipped to combat the pathogen. This often includes individuals with weakened immune responses, such as those with chronic illnesses, the elderly, or young children. Additionally, the host must have specific receptors or cellular environments that allow the pathogen to attach, invade, and replicate. Without these conditions, the pathogen is unlikely to establish an infection.
How does the flu reproduce and survive in the human body?
To continue to replicate and exist, a flu virus must be in a host animal's cells. They can be grown in cultures (and eggs) for creating vaccines, but need a living host for long term activity and to "live".
) For a pathogen to be successful they must do all of the following EXCEPT?
For a pathogen to be successful, they must effectively invade a host, evade the host's immune response, and reproduce to spread to new hosts. However, they do not need to maintain a long-term relationship with the host; in fact, many successful pathogens can cause acute infections that lead to rapid transmission without long-term survival in the host. Therefore, the statement about maintaining a long-term relationship is the exception.

What is vector in plant pathology?
A vector is an organism that can carry pathogen(= disease causing organism) from infected plant to a health plant. Generally, a vector is an insect, a nematode, a fungi, or insect like organisms e.g. spider mites. To qualify as vector, the organism must have the ability to acquire the pathogen, must be able to retain the pathogen for some length of time and lastly it must be able to inject it into a suitable/susceptible plant. The relationships between the vector and pathogen can be described as simple if the pathogen does not circulate or replicate in the vector or complex if the pathogen replicates or circulate in the vector. In the latter case, the vector also acts as the host of the pathogen.
Can you live without sleep?
No, you must sleep to survive
How can seals live in the cold seas?
they must live in the cold sea to survive cause they cannot survive in the warm climate
What parasite must live on there host at all times?
That is the definition of a parasite. I believe. They have to have a host to live. Im pretty sure anyway
5 elements that makeup the chain of infection?
The chain of infection consists of five key elements: the infectious agent (pathogen), the reservoir (where the pathogen lives), the portal of exit (how the pathogen leaves the reservoir), the mode of transmission (how it spreads to a new host), and the portal of entry (how it enters a new host). Each element must be present for an infection to occur, and breaking any link in the chain can help prevent the spread of disease.
What is the difference between a primary and an opportunistic pathogen?
Primary Pathogens are the microorganisms that cause diseases in healthy individual. Opportunistic Pathogens are the microorganisms that are ordinarily in contact with the host and cause disease when the host's resistance is low.
