*  The evolutionary and coevolutionary consequences of defensive microbes for host-parasite interactions. - Oxford Neuroscience
BACKGROUND: Animal and plant species can harbour microbes that provide them with protection against enemies. These beneficial microbes can be a significant component of host defence that complement or replaces a repertoire of immunity, but they can also be costly. Given their impact on host and parasite fitness, defensive microbes have the potential to influence host-parasite interactions on an evolutionary timescale. RESULTS: Using a phenotypic framework, we explore the evolutionary and coevolutionary dynamics of a host-parasite interaction in the presence of defensive microbes. We show that costs of host-defensive microbe systems are critical in determining whether a defensive microbe based system or an immune system provides better host protection investment. Partitioning the coevolutionary dynamics yields testable ...

*  On Genetic Specificity in Symbiont-Mediated Host-Parasite Coevolution
Author Summary Coevolution between hosts and parasites is believed to be central to a number of biological phenomena, most notably the observed patterns of biodiversity and the origins of sexual reproduction. However, classical mathematical models of host-parasite coevolution account neither for the hosts' use of bacterial symbionts for protection from parasites, nor for the potential and observed complexity of genetic interactions between the coevolving species. In this article we address both challenges by simulating a large number of models of host-symbiont-parasite coevolution based on randomly generated genotype interaction patterns. We demonstrate that the degree of

*  Andrena bucephala - Nomada host parasite specificity | BWARS
From Ed Phillips:. I was fortunate enough to find a new colony of Andrena bucephala last year, at my local churchyard in Warwickshire. This year I've been spending quite a bit of time watching and photographing there. Much activity involves sharing of communal nest entrances; I understand that this is a feature of A. bucephala nesting behaviour.. The colony is parasitised by Nomada hirtipes, with a reasonable amount of activity. I've also been surprised by the number of much larger flava-type Nomadas that are also invariably lurking at the nest holes. Today I saw two of these female Nomadas (at separate occasions) actually enter a communal A. bucephala nest hole. After several minutes they had not emerged.. I was wondering what could be deduced by this behaviour if, as I've assumed up to now, there there is a high degree of host/parasite specificity with Andrenas and Nomadas. Presumably, one of the following;. ...

*  Interactions between frequency-dependent and vertical transmission in host-parasite systems | Proceedings of the Royal Society...
We investigate host-pathogen dynamics and conditions for coexistence in two models incorporating frequency-dependent horizontal transmission in conjunction with vertical transmission. The first model combines frequency-dependent and uniparental vertical transmission, while the second addresses parasites transmitted vertically via both parents. For the first model, we ask how the addition of vertical transmission changes the coexistence criteria for parasites transmitted by a frequency-dependent horizontal route, and show that vertical transmission significantly broadens the conditions for parasite invasion. Host-parasite coexistence is further affected by the form of density-dependent host regulation. Numerical analyses demonstrate that within a host population, a parasite strain with horizontal frequency-dependent ...

The ability to serologically identify some 140 different O groups has greatly facilitated the study of host-parasite interaction with infections due to E. coli. We studied 277 patients with infections of the urinary tract, blood, or other extra-intestinal sites. Our experience reveals that O groups 1, 4, 6, 25, 50, and 75 account for 60 to 70 per cent of the groupable strains among extra-intestinal specimens from diseased patients. Feces was the reservoir among 80% of patients with urinary tract infection: 66% of fecal specimens from diseased patients contained at least one of the common serogroups in contrast wih only ...

*  Impact of protozoan cell death on parasite-host interactions and pathogenesis | Parasites & Vectors | Full Text
Trypanosoma brucei, i.e. the causative agent of sleeping sickness in humans and of nagana in cattle can undergo apoptosis in the mammalian bloodstream form (BSF) [20, 21] and the procyclic form within the midgut of the tsetse fly [22, 23]. In the mammalian bloodstream, parasitemia of T. brucei increases and decreases periodically and this is partially due to effective antibody-mediated immune responses of the host and antigenic variation of the major surface glycoprotein of the parasite. However, the cell density of T. brucei is also regulated in axenic cultures in the absence of any host-derived immune effectors. After reaching a cell density-dependent threshold, further expansion of the cell population is restricted by differentiation from the replicating long slender (LS) form to the non-dividing short stumpy (SS) form [24]. Subsequently, the parasite density even decreases and this is accompanied by the occurrence of ...

We have examined genetic variability in parasites in the context of ecological interactions with the host. Recent research on Echinococcus, Giardia and Cryptosporidium has been used to illustrate: (i) the problems that parasite variability and species recognition pose for understanding the complex and often controversial relationship between parasite and host occurrence; (ii) the need for accurate parasite characterization and the application of appropriate molecular techniques to studies on parasite transmission if fundamental questions about zoonotic relationships and risk factors are to be answered; (iii) our lack of understanding about within-host interactions between genetically heterogeneous parasites at the inter- and intraspecific levels, and the significance of such ...

Author Summary Contrary to the traditional view that immunity in invertebrates is limited to innate mechanisms, recent studies have shown that these several species of protostome invertebrates express putative immune receptors that can be somatically diversified in a way resulting in an analogy with Immunoglobulins or T Cell Receptors of vertebrate species. Other studies have shown the existence of putative antigenic variant counterparts in their specific parasite, as would be expected in an

*  Publications | The Pirbright Institute
Toxoplasma gondii is recognized as a widely prevalent zoonotic parasite worldwide. Although several studies clearly identified meat products as an important source of T. gondii infections in humans, quantitative understanding of the risk posed to humans through the food chain is surprisingly scant. While probabilistic risk assessments for pathogens such as Campylobacter jejuni, Listeria monocytogenes or Escherichia coli have been well established, attempts to quantify the probability of human exposure to T. gondii through consumption of food products of animal origin are at early stages. The biological complexity of the life cycle of T. gondii and limited understanding of several fundamental aspects of the host/parasite interaction, require the adoption of numerous critical assumptions and significant simplifications. In this study, we present a hypothetical quantitative model for the assessment of human exposure to T. gondii through meat products. The model ...

*  Malaria parasite circadian clocks | Proceedings of the Royal Society of London B: Biological Sciences
Our data provide a rare demonstration of the impact that circadian rhythms have on fitness. Specifically, we reveal that parasites forced out of synchrony with the host's schedule paid substantial costs, as a single phase shift reduced both in-host replication and the production of transmission stages by around 50 per cent. These costs are likely to have broad implications for parasite survival and reproduction. Malaria parasites must optimize the trade-off between investment in replication for in-host survival and the production of gametocytes for between-host transmission. Parasites with low replication rates are vulnerable to clearance by the immune system, anti-malarial drugs and are poor competitors in genetically mixed infections [33-37]. For example, subtle differences in the replication rate of co-infecting strains ...

Synopsis: Parasitology: An Integrated Approach, provides a concise, student-friendly account of parasites and parasite relationships that is supported by case studies and suggestions for student projects. The book focuses strongly on parasite interactions with other pathogens and in particular parasite-HIV interactions, as well as looking at how host behaviour contributes to the spread of infections. There is a consideration of the positive aspects of parasite infections, how humans have used parasites for their own advantage and also how parasite infections affect the welfare of captive and domestic animals. The emphasis of Parasitology is on recent research throughout and each chapter ends with a brief discussion of future developments. This text is not simply an updated version of typical parastitology ...

*  Songbirds resist sympatric parasites | Open Science
We conducted reciprocal infection experiments to inoculate song sparrows with sympatric or allopatric lineages of Plasmodium. Host and parasite origin interacted to predict infection success, a pattern consistent with birds having a home-field advantage in defending against their sympatric parasites. However, the magnitude of this advantage appeared to vary geographically: eastern, but not western, song sparrows were less susceptible to infection by sympatric parasites. Evolutionary and ecological interactions with sympatric haematozoa may, in some cases, provide birds with a parasite-mediated home-field advantage, but the outcome of host-parasite interactions may not be constant over the landscape.. The vast majority of experimental infection studies have used plant or invertebrate hosts [8]. The minority ...

*  "The Roles of Ecological and Evolutionary Influences in Providing Struc" by John J. Janovy Jr., Richard E. Clopton et al.
Parasite species assemblages currently are thought to range from isolationist to interactive, their dynamic properties being related to the number of species and types of hosts involved. The literature contains few experimental tests of this concept, however, and many of the host/parasite systems studied to date are not amenable to experimental manipulation. In this review, the presence of a parasite species, in a sample of host individuals, is considered to be an evolutionary phenomenon, but the parasite's population structure is considered to be an ecological one. Studies that allow evaluation of these two influences are comparative in nature and include data from a series of homogeneous samples of host populations. A lottery model is presented, in which hosts acquire their assemblages of ...
