| World's first movies on bird flu - This is the first part of bird flu the virus - This animated, 45 minute, movie arms you with detailed information on virus, it answers those questions that had been bothering you but did not know whom to ask?, like how can a "bird virus" infect human beings, How can the virus jump from chicken to humans? If this H5N1 virus has been present since 1997, why is there no medicine or vaccine available even today to fight it?

and Becky through electron microscope
|
Dr. Jenny elucidates the difference
between a bird flu virus and a human flu virus
|
Influenza viruses are of three types
A, B,C
|

|

between influenza and other viruses
|
|
|
 |
 |
|
Becky learns why vaccines don't
work

Virus has
previous jumped to human beings from animals before
also

There are combinations for which
antibodies are present
|
|
There
are two parts of this movie both are sold separately, this
is the part 1, the part 2 deals with viral transmission
to humans.
Virus
is a strange entity it is "un-dead" and when it
comes in contact with a living cell it becomes alive and
causes diseases and deaths. This movie takes you onto a
journey of discovering the virus. The movie explains it
in an easy to understand, interactive format. It answers
many questions, some of them are given below. There are
two more movies on bird flu, go to their pages on our site
to get more details about this virus

there no medicine or vaccine available even today to fight
it?
18.What is virus, what does it look like, how does it function?

| Q1: |
can u give me some information about flash animation on bird flue |
kisna |

|
| |
|
| Q2: |
can you give me web site so that i can see full video of virus |
sonia |

| Ans: |
|
| |
|
| Q3: |
what is the structure of the gene arrangement of H5N1 virus |
Okudo Chioma Catherine |
11/3/2008 |
| Ans: |
The H5N1 genome has eight segments (1–8), each segment codes for a protein: polymerase (PB2), polymerase (PB1), polymerase (PA), hemagglutanin (HA), nucleocapsid (NC), neuraminidase (NA), matrix protein 2(M1, M2) and nonstructural protein (NS) respectively. These eight genes make up the flu’s genome, or complete collection of genes |

|
| Q4: |
what are the clinical signs and symptoms in birds and is there any diagram to show us that? |
Dr.omar |
20/2/2007 |
| Ans: |
In LPAI, in poultry, mostly clinical signs are absent, indications are mild respiratory disease, depression, and decrease in egg production; Clinical signs for HPAI are: depression, excessive thirst, open mouth breathing, loss of appetite, decreased egg production, nervousness, swelling or blue discoloration of combs and wattles, edema around eyes, coughing, star gazing, sneezing, rales and excessive lacrimation. Sudden death can occur. We are putting up a flash based diagram in article section. |
| |
|
| Q5: |
how virul living or non living organism? |
sumit |
19/2/2007 |
| Ans: |
Viruses are codes that are floating in a medium whether air, water and blood or involuntarily sticking to surfaces something like dust particles. However once they come in contact with a receptive living cell they become active, you can imagine them to be like an autorun CD that is inert or non-active when outside a computer (analogous to a cell) but automatically runs its program (or becomes “alive”) when inserted in a CD drive (a cell receptor in case of a virus) and takes over the computer. |

|
| Q6: |
Please show me about H5N1 antigenic shift and antigenic drift animation. |
Numhom |
26/1/2007 |
| Ans: |
Antigenic drift: It is a continuous but permanent mutation in the genetic material of the virus; it modifies the shape of the receptors of the virus so that antibodies effective against it before fail to attach to it, making the previous vaccine useless. Here (virus remains the same. In case of antigenic shift, an entirely new virus is formed due to combination of virus of two different species. Here large fragments of genes are replaced by different ones. Influenza virus readily undergoes this. |

| Q7: |
i am very thankful to you and like your efferts to spread the knowldge.again i appriciate you. |
ammara |
21/11/2006 |
| Ans: |
Thanks ammara, it is the generous appreciation of visitors like you that spurs us on to do more, please do keep on asking questions and giving us feedback. |
| |
|
| Q8: |
what did ment by influenza.from wich language is this word. |
ammara |
17/11/2006 |
| Ans: |
Influenza (flu), is an infection of birds and mammals caused by an RNA virus. It originated in 15th century Italy from “influential” meaning in ('in', of course) and fluere ('to flow'). It referred to the power the movements of the cosmos held over inhabitants of earth. Used in 1439 by Italian doctors for influenza di febbre scarlattina, or 'scarlet fever'. It first came into English in 1743 when it was borrowed from an outbreak in Europe to connote a disease resulting from miasma (bad air). |

|
| Q9: |
explain the life cycle of the virus H5N1. |
Noovera |
21/7/2006 |
| Ans: |
The life cycle consists of stages like attachment, penetration, uncoating, biosynthesis, assembly and release of virions, since this space is insufficient we are including a more detailed answer in our forums. |

|
| Q10: |
hemagglutinin detailed structure |
mohammed mahmood |
4/4/2006 |
| Ans: |
The detailed structure and description of hemagglutinin is not there in this animation, we are right now developing a separate product for hemagglutinin and neuraminidase containing detailed mechanism, meant for medical and microbiology reference but it will take some time. The present product is directed towards those with high curiosity but not having advanced knowledge to quench it. |
| |
|
| Q11: |
i want diagrammatic representation of life cycle of H5N1 |
suresh kumar.H |
6/2/2006 |
| Ans: |
This has been a regular request by a lot of people, the good news is that we are in the final stages of designing such a diagram, the only debate is should it be in printed poster format or in flash format, thanks for the request in next 15 days we will release such a diagram, please keep on checking this page |

|
| Q12: |
How do avian influenza virus mutate? |
suresh kumar |
3/2/2006 |
| Ans: |
by mainly three processes 1) antigenic shift - two different AI virus infect a cell, nucleic acid mix, new virus emerges 2) antigenic drift - virus affects a cell in the reformation of virion - error takes place, new virus slightly different from old 3) recombination - same virus say H5N1 , infects a cell, re-assortment of genes takes place, H5N1 that emerges is slightly different one, actually this is the method H5N1 has been using to evolve |
| |
|
| Q13: |
what is main overview of bird flu? |
suresh kumar |
3/2/2006 |
| Ans: |
We will focus only on "H5N1”, bird flu with reference to birds has been extremely virulent causing nearly 100% fatality in domestic birds, mainly spreads through water birds to domestic, has been infecting Asia and some parts of Europe, in context with humans the mortality has been 50-60% with no proven human - human transmission, largely limited to Asia, spreads due to close contact with infected birds. Is not airborne and there is no vaccine, with antiviral medicine “Tamiflu” still not efficac |
| |
|
| Q14: |
what kind of treatment is provided for protection of avian influenza virus? |
suresh kumar |
3/2/2006 |
| Ans: |
Please refer to the article section |
| |
|
| Q15: |
How are "bird flu" viruses different from "human flu viruses"? |
suresh kumar |
3/2/2006 |
| Ans: |
Gene structure, glyco proteins and the way the receptors bind to epithelial cells, human AI virus binds to non-ciliated ones while bird virus primarily binds to ciliated ones |
