Great science writing, but fewer case histories would suffice

"Parasite Rex" is great science writing. For readers familiar with evolutionary and ecological theories, they will meet these theories in a new guise. For readers not familiar, Zimmer has a talent for explaining complex ideas in a very simple fashion. In only one case did I detect a minor oversimplification: there is more to generating novel antibodies than shuffling genes. My only complaint about style is that Zimmer sometimes tries to make the reader horrified at what parasite does to prey, and when the prey is a lower order animal like a caterpillar, I am doubtful that having its insides eaten is as horrible as it sounds. I say this as a person who only eats free range meat. As regards content, fewer case histories of individual parasites would suffice to illustrate the ideas, and for me at least, make for an even more interesting book.

I was very surprised to learn of the strong environmental component to such autoimmune diseases as Crohn's: while once thought to be characteristic of a few ethnic groups, e.g. Jewish, it has become much more common in other groups as sanitation has improved, and the immune system has fewer parasites to fight off. Zimmer suggests parasites play a critical role in ecological balance, and points to some compelling case histories. Parasites are often able to control behavior of their hosts, and thus are a potentially important source of new behavioral drugs.

A Jarring Read, but Absolutely Enthralling

I don't know why, but I find parasites interesting. However, I wasn't exactly looking for a book on this particular subject; rather I merely stumbled upon it. When I go to the book store I typically peruse my favorite sections, one of which is science. On the shelf I came across the title "Parasite Rex"... so I picked it up "King Parasite...huh." Then I made the mistake of reading the back of the book and found out what it was about. I had to buy this book immediately!

I'm always reading, so I had to finish up a couple other books before I could start reading this one, so I waited patiently in eager anticipation. I'll usually read two or three books at a time, and when I finally got freed up, I started this book. I didn't read another book until I finished this. It is one of the most engrossing scientific books I have in my collection. Carl Zimmer is actually a phenomenal writer. I'm not a scientist, but I enjoy reading about it and it's written in a manner just about anyone should be able to understand. It's like a science report that flows, but doesn't sound overly scientific, yet it's still science!

Parasite Rex doesn't just deal with one specific parasite, like the title might suggest, rather it's a veritable tour of the parasitic world. The reader finds themselves enthralled with each creature. It really changes your perspective on the world as a whole, realizing that the major importance of sex is so that we can vary up our genetic code to better defend against such parasites. It also makes you realize that for all intents and purposes the fetuses of mammals would also be parasites as well because they force the mother to change her chemical reactions to support the fetus. Also the mother treats the fetus initially as a threat to her system. I personally found all this very fascinating and made me realize that perhaps Agent Smith in the Matrix, when he assessed the human race as a virus, probably should have identified them as a parasite.

The book is also terrifying in some regards because there are parts where it explains where parasites go wrong. Parasites are essentially programmed to thrive in specific locations in your body (or some other creatures). So a parasite that gets lodged in your brain, but it's supposed to be in your stomach could end up killing the host. Or screw up which species it attaches itself to. From what I gathered, the parasites main focus isn't to kill the host, but to feed off of the host's life, so when a parasite is in the wrong spot it executes its program, but it ends up having terrifying affects on the host.

In the end this was a phenomenal read and I can't recommend this enough. In fact I will probably read this a second time because when I read it the first time through I read it pretty quickly. One other thing this book made me not want to do is visit any location that's in the central area of the earth, such as the Amazon. Considering there have been 2,500 different parasites identified in one small location. Carl Zimmer is seriously the kind of writer we need in science to help transfer complex knowledge to the lay population.

I love this book

I bought this book quite a long time ago and forgot to review it until now...I am a parasitologist and this is one of my favorites. Zimmer is funny and engaging and scientifically accurate--I HAVE GOT TO READ THIS AGAIN SOON.

4.5 Stars for Raising Questions I Felt Better Once Having Remained Ignorant About, But Am Glad That Changed

I read the 2001 paperback of the 2000 book. It is very well written, which can't be said about all books on the topic. It is clear, at times funny, macabre, eye-opening, repulsive due to topic, fascinating and thought provoking.

Parasites outnumber other forms of life 4:1, are much more ubiquitous than commonly thought, have been essential for evolution and have directly influenced human DNA. (Not even considering mitochondria getting integrated in most forms of life.) Parasites make it necessary to revise the tree of life into a bush of many merging branches. Human cells within the average human are outnumbered by a factor of ten by non-human cells. Getting knowledgable about parasites is much more important a topic than the obvious peculiar yuk effect. Though I promise you that this book will fulfill the latter to the fullest as well.

I thought I knew a bit about parasites. For example those wasps which lay eggs in other invertebrates. To begin with, I didn't know that there were some 200,000 parasitic wasp species out there. I had also no idea, how EXACTLY some of them work. Like the species, whose two eggs, one female, one male, subdivide in the host, to produce ever more eggs, with the females developing into different classes of maggots, such as the soldier maggots whose only job it is to kill other parasitic wasps' maggots in the host - and all but one of the male siblings. Or that the social parasite, the cuckoo baby is able to mimic the sound of a CHOIR of eight singing host bird babies and the sign stimulus of as many youngsters in the nest to the parents' eyes. (Though the book doesn't mention that some birds cannot be fooled anyway and depose of the cuckoo (egg) and also doesn't mention that the near-by cuckoo parents may retaliate by killing all the hosts' surviving kids...) Or that there is something like plant bacteria, not as in bacteria of plants, but as in green bacteria. Being an essential part (originally parasite) of the parasite named "bad-air" aka malaria.

The book answers even the nagging question, wether there are homosexual parasites. (I wondered that ever since I read Biological Exuberance: Animal Homosexuality and Natural Diversity (Stonewall Inn Editions) about mammals and birds.) The flukes mentioned here are the first parasites I encountered (as in READING about them), which act homosexual in a benign way. To each other that is. (Other parasites - not mentioned in this book - may act homosexual in very twisted ways to procreate to the detriment of same-sex competitors.) Thinking about it: Shouldn't homosexual parasites of the former kind be our favorite parasites, if there is such a thing, because presumably they do NOT procreate, as in: in us? The book sure doesn't answer the question wether there are homosexual solidarity activists like there are for maltreated homosexual zoo animals.

Talking about questions I never knew existed: The book is full of them. Sticking with the homosexual topic, there's a fungus, which TURNS flies into necrophiliac homosexuals. As much as another parasite doesn't only fool crabs into believing that their attached parasite babies are crab babies to care for, but fooling male crabs to believe they themselves are females all of the sudden in order to (be able to) do that to begin with. If you ever sought a flabbergasting book, this will be it. Some animals have a bodyguard class against parasites (ants), others employ blind snakes as maids to free the nest of parasites (owls). And how much DNA itself can get parasitic in various ways sure wasn't on my radar of existing topics.

The book talks about allergies caused by the modern lack of parasites, complete fusions of life, the parasitic origin of sexuality, and that humans may be considered as parasites in the gaia concept. As stupid parasites that is, which are those defined who kill their host. Some readers may be a little lost with this spirituality capping ending of the book. As a Rasta, personally, I am not. As such, I was surprised to find welcome information on the spread of parasites through colonialism. Not only via the conquerors' imported bugs and slavery's transmission, but via relocating cattle within Africa. And via forcing the indiginous populations to live and work in areas unsuited for humans and/or their cattle. All of that having caused most severe and lethal epidemics. The Western apologetic lore has it that their colonial doctors brought healing power to their conquered new lands. (The book doesn't mention that some vaccines were necessary, because the diseases had been imported in the first place and that some FORCED cattle vaccinations occasionally caused more deaths in livestock than the diseases themselves, sometimes intended, sometimes not.) In today's shifted colonial world, the book warns (indirectly) against huge dams, which dramatically expand standing water, which in turn dramatically expands the habitat of dangerous to human parasite carrying snails. In case you are wondering how dams are colonial, please read Confessions of an Economic Hit Man. I find it also interesting to read that Konrad Lorenz didn't change his views of parasitism in the Nazi sort of way at all - even not a few days before his death in 1989. As celebrated as he gets in Western school books, it is usually not known (and not elaborated in this book) that he fully embraced the Nazi party and became an eager member immediately after Hitler marched into Austria. On a more enlightening subject around parasites, I didn't consider before I read this book that human (pre-)history can be reconstructed via tapeworms.

I have a little bit of criticism. Some things are sketchily mentioned only. There is a parasite which eats the flesh of the human face. Ok, horrid. But if I think about it after the initial impulse to turn the page immediately: How exactly do I have to imagine that? What consequences does this have? How is that livable? No answers in this book. The captions of the FEW black and white pictures on 16 pages in the middle of the book are sometimes not that precise. With that parasite, which replaces a fish's tongue, the caption is all we will ever read in this book about that parasite. How does it eat the tongue, i.e. getting into the mouth? How does the parasite help the fish grabbing food? How does the parasite mate? Does it cause infected fish to french kiss or what? If I want to research that, I would have appreciated the parasite's name. Or the name of the host. The caption only says a crustacean in a fish. Wow, that's precise! I don't even know, where on this planet I should look into a fish's mouth before eating it. Well, I was able to find some answers elsewhere nevertheless: The parasite is called Cymothoa exigua, lives in California and only in the mouths of Lutjanus guttatus aka spotted rose snapper. The parasite crawls under the tongue and severes its blood supply in a vampiric manner, causing the tongue to wither away to be replaced by the growing tongue with eyes. I still don't know how it procreates, so anybody who does know, please leave a comment with source. Five years after the book had been written, the first fish with second tongue was found in EU waters (in the UK). The book may not be that incredibly up to date, with some issues still pending when written. For example on the eradication of some parasites. As of 2008 some more countries could be added to the list of eradicated guinea worms, but with other countries still lacking behind.

The Hamilton-Zuk theory got its own book by Marlene Zuk herself: Riddled with Life: Friendly Worms, Ladybug Sex, and the Parasites That Make Us Who We Are, itself a great book about parasites, with little overlap. And if, it goes more in-depth, like with the fungus which attacks insects. If you like a coffee table book of the nasty treat, in which you can also read, which (utterly unexpected!) places in your household are the most yukky ones, "enjoy" the Canadian Human Wildlife: The Life That Lives on Us. If you are interested in more symbiotic body roomies, largely restricted to bacteria and in a systematic text book presentation, read the rather dry Microbial Inhabitants of Humans: Their Ecology and Role in Health and Disease. Much more grippingly written is Good Germs, Bad Germs: Health and Survival in a Bacterial World by a science journalist. Which is also about the history if antibiotic treatments and their failure due to mounting resistance. About former parasites, today our energy source and DNA family tree provider, mitochondria, read Power, Sex, Suicide: Mitochondria and the Meaning of Life. A more general biological approach of symbiosis is Liaisons of Life: From Hornworts to Hippos--How the Unassuming Microbe has Driven Evolution. A theoretic re-thinking, including reconstructing taxonomy and theories about gaia, read Symbiotic Planet: A New Look At Evolution.

Awesome book changes your outlook

Another excellently-written work from Carl Zimmer. This book will give you a bad case of the creepy-crawlies in parts. It will also completely change your outlook on the nature of life, because you will learn that parasites are not really the gross, "devolved" hangers-on that most think of them as, but rather a vibrant, important part of the web of life...

... that is sometimes really disgusting.

Still, an outstanding book, one that give parasitology a much-improved face. Written in Zimmer's usual clear, very readable style.

IMAGINE A WORLD WHERE parasites control the minds of their hosts, sending them to their destruction.

IMAGINE A WORLD WHERE parasites are masters of chemical warfare and camouflage, able to cloak themselves with their hosts' own molecules.

IMAGINE A WORLD WHERE parasites steer the course of evolution, where the majority of species are parasites.

WELCOME TO EARTH.

For centuries, parasites have lived in nightmares, horror stories, and in the darkest shadows of science. Yet these creatures are among the world's most successful and sophisticated organisms. In Parasite Rex, Carl Zimmer deftly balances the scientific and the disgusting as he takes readers on a fantastic voyage. Traveling from the steamy jungles of Costa Rica to the fetid parasite haven of southern Sudan, Zimmer graphically brings to life how parasites can change DNA, rewire the brain, make men more distrustful and women more outgoing, and turn hosts into the living dead.

This thorough, gracefully written book brings parasites out into the open and uncovers what they can teach us about the most fundamental survival tactics in the universe.
