Flu is caused by a pathogen (by viruses) but is not the pathogen itself, flu is the disease the pathogen causes. Flu is short for influenza which is an infectious disease of the respiratory system caused by influenza viruses.
A pathogen causes infectious disease. For instance, influenza virus is the pathogen that causes flu.
The scientific name of the pathogen that causes the flu is Influenza virus. There are different types of influenza viruses, with the main ones being type A, B, and C.
Viral pathogens cause colds, flu, and chickenpox.
Flu is neither eukaryotic nor prokaryotic. It's a virus.
for a single pathogen ... you can't. In fact you can't ever detect the "detection" process. But you can feel when your immune system is responding to pathogens: you secreat inferon and that gives you the shivers (fever), and that rotten, worn-out feeling that we refer to as "flu".
A virulent virus is a pathogen that is highly infectious and causes severe disease in its host. Virulent viruses often have a high mortality rate and can spread rapidly within a population. Examples include Ebola virus and the Spanish flu virus.
Sometimes they will develop mild flu like symptoms and have a low grade fever. With the weakened your body will recognize the pathogen and develop antibodies against it, so your reaction would be milder then contracting the actual illness.
Swine flu is caused by a virus. Viruses are submicroscopic organisms that are so small they can only be "seen" with an electron microscope. A regular microscope does not allow us to see things as small as a virus particle. See the related questions below for additional information about the pathogen that causes the H1N1/09 swine flu.
The single cell pathogen with no nucleus is a prokaryotic organism. Prokaryotes, such as bacteria, lack a membrane-bound nucleus and their genetic material is found free-floating in the cytoplasm. This simple cell structure allows them to replicate quickly and adapt to various environments.
all diseases are caused by bacteria or viruses. some example are flu (influenza virus) and swine flu (influenza A H1N1) and Meningococcemia (Meningococcus).
A vaccine contains the pathogen ( a foreign body which causes diseases/illnesses) which the virus is designed to provide protection for ie: a flu vaccine will contain a flu virus, measles has the measles virus etc... - but they have been treated so they are in effect dead and so will cause no symptoms, your body can only recognise a pathogen, it does not know that it is dead and can not harm you,so your body produces antibodies ( cells that fight off and remove pathogens from the body) to fight this vaccine, the antibodies remain in the body forever (unless you have an autoimmune/immunodeficiency illness) so when you come into contact with say the flu your body already has the antibodies and you don't get sick because your body removes the pathogen before it gets chance to take hold.
the causes of swine fluenza are pigs only kidding imonly tweleve and researching this subject my self so suck on that hahahahaha the causes of swine fluenza are pigs only kidding imonly tweleve and researching this subject my self so suck on that hahahahaha
