Question and answer
waht is the causative organism of bird flu
Avian flu is very similar to the common cold (flu) that every human being catches at least once in his lifetime. The causative organism is obviously different. Human flu is caused by Human Influenza Virus. [ Avian flu is caused by a mutant form of a virus which was initially capable only of infecting birds. This virus is labelled H5N1 (because of its surface heamagglutinin-H and neuraminidase-N molecules). You see, the reason why this virus is a threat, is because of its ability to mutate. This is because of its lack of enzymes responsible for proof-reading of the new genetic material
synthesized. Hence, everytime the virus divides, there is a new error in the genes which provides its progeny with new capabilities. This is kinda how it obtained the ability to infect humans. There was also another theory I read about where two different subtypes of avian flu viruses amongst birds mixed their genetic material when they infect the same organism, giving rise to a new subtype. ]
