    Hi everybody,

    I'm Tom, it's my first post. I'm a pretender to scientific knowledge, abandoning chemistry after the completion of a degree but still periodically getting fascinated by one thing and another.
    Lately I'm fascinated by probacteria and pathogenic bacteria. I have a question on the subject. Is it not the case that what our bodies consider to be "bad" bacteria could be "good" for some other being? And vice versa? Or is it that "bad" bacteria are generally bad wherever they go?

    Many thanks in advance for anyone's help with this matter.

    i'm sure most bacteria are good at propagating themselves - we only perceive them as bad when their attempts to multiply affect us in a negative way

    yes, I appreciate that to call bacteria "good" or "bad" is something of a misnomer. I know that streptococcus and staphylococcus are part of our oral and nasal fauna yet elsewhere are less agreeable to the human form. I mean my understanding is that bacteria can be generally categorised into those we (humans) like, such as Lactobacillus acidophilus and Bifidobacterium infantis, which are helpful to our digestion, and those we don't like, such as chlamydia and rickettsia.

    So could, for example, chlamydia be beneficial to another species and could lactobacillus be harmful to another species?

    I heard that salmonella is reptiles' normal gut fauna.

    Ya this happens a lot, like Escherichia coli is a natural part of the gut fauna of humans, but EHEC (enterohemorrhagic E. coli) are pathogenic to humans. Yet they remain a commensal organism in cows because they lack the adhesins required for pathogenicity in cows.

    Yeah, they appear to have it instead of E. Coli

    Personally I classify bacteria into naughty and Christian.

    This may seem like a random nonsensical classification, but the message is of course that so is bad and good.

    Or you can just classify them as commensal or pathogenic with respect to humans.

    Also worth mentioning that, with bacteria, the concept of species is a dodgy one.

    The strains of bacteria that thrive in your gut, and help you thrive, would most likely die (rather than causing any good or ill effects) if transferred to the guts of any other animals, and vice versa.

    The best we can talk about is related strains of bacteria, but those lineages may have been separated by very long periods of time. There are, of course, examples of pathogens that jump from one animal species to others, HIV (in this case a virus not a bacterium) being perhaps the most famous recent one. Jared Diamond's Guns, germs and steel provides a fascinating accoutn of the 'motives' of pathogens, their evolution, and the ways in which we humans interact with them, both good and bad.

    Many thanks everyone for your illuminating responses. I think from now on I'll refer to them as naughty and christian. It makes so much more sense.

    No you're a sense.
    Oh no, exposed!!

    thetada, I can't see how the link you posted relates to this thread or the Bio forum at all. Granted there's been some joking around in here but I'd rather you not post links to other threads just to poke fun at other people's behavior.
