If you are interested in Acanthamoeba species, then this is the book to turn to. Kahn explores every aspect of this protozoan genus and, unlike many books on pathogens, he reminds us that Acanthamoeba is essentially an environmental organism that is also an opportunistic pathogen. The thoroughness of the book is complemented by its logical organization with discrete sections that provide information on the organism's biology, life cycle, infectious nature and mode of action, the host immune response that it provokes and the therapeutic strategies that are available to us. Furthermore, the 'Trojan Horse' idea is explored with respect to its 'endosymbionts', comprising viruses and numerous bacteria that not only evade digestion by this microbiological predator but carry on their life style with, in some cases, an enhancement of their pathogenicity. But before you rush out to get a copy, you need to consider the price (it is high), and consequently there would be an expectation of higher quality diagrams. Overall, a book well worth considering.
