Description

This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host.� It examines the triggering events which can factor into these changes, such as reduction in the host�s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality.� The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. �The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host�s protective natural microflora.� The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts. � �Typham this is the title: The Rasputin Effect: When Commensals and Symbionts Become Parasitic
