    If this is real, then this is the game of life-and death being played at microscopic level.

    Predator(WBC) chases it's prey(Bacteria) and at last manages to devour it. Even a microscopic life like bacteria instinctively fights for it's survival.

    So, is this real? It's cool man.
    Also, 1 or 2 seconds into the animation, a second bacteria enters the picture and is seen in the proximity of the WBC, but the WBC keeps chasing the first bacteria, why is that ?
    Does it have intelligence of its own? Or does a particular WBC chase only a particular type of bacteria ?

    Wow, you caught that. I thought no one would have noticed it, as they would not have thought to look for it, since they would not have know the Mech behind it. Great eyes Bro :thumb:

    Its a very big process, which runs for twenty or so pages in pathology, but I will explain in a nutshell.

    The Bacteria have foreign antigens in their cell surface akin to foreign uniform. Now the WBCs, the police force does not recognise the Bacteria(foreign uniforms) unless it is initiated/ made to realise that the bacterial uniform/antigen is foreign. So when the WBCs are made to realise that they are foreign, they start the hunting process when they encounter such bacteria on which they are "initiated". So when the WBC makes a lock on, on the Bacteria, it follows it by the process of "Diapedesis or amaeboid movement"-. This process is mediated by chemicals and it is called as Chemo-taxis- that is Chemical mediated Movement. The chemicals are usually the Bacterial toxins release by the bacteria, though there are several chemotactic substances available. The Chemotaxis works only till a particular distance. So when a WBC follows the bacteria, there are several reasons why it will follow thee trail, one being it is initiated to do follow and capture the bacteria, other being the chemotaxis which provides the movement stimulus for the WBC. So it will continue down the trail it was following;). Hope my answer is clear enough

    Yeah, my Awesome quotient is very high. :truestory:

    Thanks for the explanation, dude.
    So, basically the WBC locks on to a foreign entity (bacteria), registers its toxin trail and keeps following it (chemotaxis).
    Man, Evolution is such a beauty.

    fake.
    its animation.

    non-flagellated bacteria cant swim..
    the bacteria seems diplo-cocci ( 2 bacteria in pair), they r non motile

    But you have to admit the animation is good :)

    And it also does a very good job of explaining what happens:)

    It is a Neutrophil chasing Staphylococcus aureus, filmed in around 1950 at Vanderbilt University.

    His argument is right that the staphylococcus is immobile. But what we see there is more of a passive drift than a active mobility I think if it is indeed the actual photography:notsure:

    You want to hear about Interleukin 1 ,2 and TNFs and IGs and opsonins and , the various enzymes inside the WBCs( i think here it is a macrophage:notsure:) et al here? And the actual method in which the Macrophage eats up the bacteria?:dude:

    If so, go learn it yourself in the Med colleges :taunt1::troll:

    Actually for a moment I thought there was an analogy here. Predator (UCAV)= WBC fighting the bacteria= paki tangos !!

    They can run, but they can't hide!!

    dont have time to read ... :bored:
    but medical stuff really interest me .. :hmm:
    i should have chosen Medical rather than Engineering, but cant do much about it after 2 years ... :cool2:

    Edit : you edited your post :dude: ..that's fukin cheating :fu:

    Thanks for posting Amit. Great eyes for those that noticed the second bacterium. Great explanation Maddy. Great identification of non-flagellation drkrn. Also, great simile Yusuf.

    However, how many of you noticed that the WBC has a tail?

    You didn't use the word "antibody" even once.

    I have some exposure to image analysis of Natural Killer T Cells, but I have never seen a tail like thing before.

    Anyway, do bacteria have a cell membrane and a wall, or only membrane?
