ECOLOGICAL PERSPECTIVES ON HOST-PARASITE COEVOLUTION
… universally acknowledged that polymorphism at host immunity loci and corresponding parasite antigenicity loci, maintained by coevolution in pathosystems, is common and can persist for millions of years. Such polymorphisms and how they persist or break down are both fundamentally interesting and …

Host-Parasite Interactions Within Food Webs
… employed in nature, yet the effects of parasites are often thought to be minimal, and the vast majority of studies fail to consider parasites and their effects on host organisms. This is likely a problem, as the magnitude of parasite-mediated effects on their hosts can be quite large. …

Interrogating Host-Parasite Dynamics During Plasmodium Liver Stage Infection
… health burden and is caused by the apicomplexan parasite Plasmodium. Plasmodium spp. are transmitted by an Anopheles mosquito and require both host and vector to complete their life cycle. Once in the host, parasites travel to the liver and undergo an obligatory and asymptomatic liver stage. This …

Larval trematode populations and host-parasite interactions in Cerithidea Californica
<p>Cerithidea california is examined to determine the fecundity of the parasitic trematode species in its gonad. Five species of trematodes are studied (Cloacitrema michiganensis, Euhaplorchis californiensis, Parorchis acanthus, Himasthia rhigedana, and Acanthoraryphium sp.). Their fecundity is …

Investigations on the host-parasite interface of a mycoparasite system /
… of Choanephora cucur - bitarum and the host-parasite interface, after infection with Piptocephalis virginiana , were examined in detail. The cell walls of C_. cucurbitarum were determined to be composed of chitin (17%), chitosan (28.4%), neutral sugars (7.2%),uronic acid (2.4%), proteins …

Predators alter host-parasite interactions via trait-mediated indirect effects
… in a genotype specific manner, they influenced parasite fitness, and affected prey life history. All of these effects have important implications in disease dynamics. This study highlights the importance of predator-induced trait-mediated indirect effects on host-parasite interactions and more …

Deciphering host-parasite molecular networks mediating resistance to toxoplasma gondii
… an obligate intracellular apicomplexan protozoan parasite that infects about one-third of the world population, with estimated medical costs and loss of productivity in the USA alone amounting to about US$3.1 billion annually. Additionally, in the USA, T. gondii is the second leading cause of …

Host parasite interaction in a mouse model of inflammatory bowel disease
… world, where infection with intestinal parasites is common.The hygiene hypothesis suggests lack of infection predisposes to the development of IBD ingenetically susceptible people. However, little is known immunologically about how gutparasites alter IBD progression. We have used mdrla …

Host-Parasite Interrelations: Bacterial Adherence to and Invasion of Epithelial Cells
<p>Enteroinvasive Escherichia coli (EIEC) preferentially invaded multinucleated HeLa cells which arose naturally in monolayer cultures at a low frequency. Data suggests that enhancement of the penetration step accounts partly for increased invasion of multinucleated cells. Treatment of HeLa cell …

Host-parasite cophylogeny and rates of evolution in two rodent-louse assemblages
… increase understanding of associations between hosts and their parasites. This study uses molecular data to test the hypothesis that members of two rodent families (Geomyidae and Heteromyidae) and their associated lice (Geomydoecus and Fahrenholzia, respectively) show a statistically significant …

Characterisation of Host- Parasite- Microbiota Interactions that Drive Hatching in Trichuris Species

CRABS & ‘CROBES: THE TRIPARTITE RELATIONSHIP OF A HOST, PARASITE, AND THEIR RESPECTIVE MICROBIOMES
… Yet, while studies have investigated host-parasites and microbiomes separately, how the two systems interact and influence each other has only begun to be explored. This relationship among hosts, parasites, and microbial communities changes the dynamic of host-parasite evolution from a …

An investigation into the host-parasite interrelationship between Common Swifts and Hippoboscid Louse-Flies
… relationship where resource transfer between a host and parasite occurs. This results in the sub-optimal expression of host life-history traits and a consequent reduction in host fitness. The Louse Fly, Crataerina pallida (Diptera: Hippoboscidae), is a monoxenous haematophagous nest ectoparasite …
