According to current thinking, a parasite’s transmission mode will be a major determinant of virulence, defined as the harm induced by parasites to their hosts. With horizontal transmission, virulence will increase as a byproduct of a trade-off between fitness gained through increased among-host transmission (infectivity) and fitness lost through increased virulence. With vertical transmission, virulence will decrease because a parasite’s reproductive potential will be maximized only by… 
Vertical Transmission Selects for Reduced Virulence in a Plant Virus and for Increased Resistance in the Host
TLDR
Evidence is provided of the key role that the interplay between mode of transmission and host-parasite co-evolution has in determining the evolution of virulence in plant virus Cucumber mosaic virus in its natural host Arabidopsis thaliana.
Virulence and transmission modes in metapopulations: when group selection increases virulence.

TLDR
Using the adaptive dynamics framework, it is shown that spatial structure can increase ES virulence when pathogens are mostly vertically transmitted, and that symbionts that are horizontally transmitted should respond more to a change in spatial structure than symbiont that are vertically transmitted.
The evolution of parasitic and mutualistic plant-virus symbioses through transmission-virulence trade-offs.
TLDR
It is shown that ecological bi-stability is possible in a very simple discrete-time epidemic model and that mutualism can out-compete parasitism in the long-run, and that evolutionary branching can occur with subsequent coexistence of mutualistic and parasitic virus strains.
Phenotypic shift in Wolbachia virulence towards its native host across serial horizontal passages
TLDR
Wolbachia can rapidly change its virulence when facing new environmental constraints, and the potential mechanism(s) underlying this phenotypic change is discussed, which are likely to be crucial for the ongoing radiation of Wolbachia in arthropods.
Erratum to: Role of trade-off between sexual and vertical routes for evolution of pathogen transmission
TLDR
It is shown that the shape of the trade-off between the two transmission modes significantly affects pathogen evolution, and while vertical transmission dominates for concave and sigmoid trade-offs, sexual transmission is most commonly observed under convextrade-offs.
Evolution of early male-killing in horizontally transmitted parasites
TLDR
It is shown that horizontal transmission is a mechanism enabling vertically transmitted bacteria to evolve fully efficient MK under a wide range of host and parasite characteristics, especially when the efficacy of vertical transmission is high.
Virulence determinants in a natural butterfly-parasite system
TLDR
Although parasite loads and genotypes had strong effects on virulence, inoculation dose, host sex and age at infection were also important, and the need for a detailed understanding of specific host-parasite systems for addressing theory is emphasized.
The evolution of transmission mode
TLDR
Research on the evolutionary mechanisms leading to different transmission modes, including changes in transmission associated with host shifts and with evolution of the unusually complex life cycles of many parasites, is reviewed.
Interactions between the Parasite’s Previous and Current Environment Mediate the Outcome of Parasite Infection
  • M. Tseng
  • Biology, Medicine

  • 2006
TLDR
The results demonstrate that parasite virulence was mediated by a cross‐generational effect of the environment and that the overall outcome of infection was modified by variation in both the parasite's and host’s environments.
Genotype-specific interactions and the trade-off between host and parasite fitness
TLDR
It is proposed that different levels of compatibility dependent on genotype by genotype interactions might lead to different amounts of resources available for host and parasite reproduction, as the total resource pool would not be constant.

TRADEOFF BETWEEN HORIZONTAL AND VERTICAL MODES OF TRANSMISSION IN BACTERIAL PLASMIDS
TLDR
The tradeoff hypothesis, which predicts that the density of uninfected hosts in the environment should determine the optimum balance between modes of parasite transmission, and evolutionary predictions using conjugative plasmids and the bacteria that they infect are tested.
Virulence, parasite mode of transmission, and host fluctuating asymmetry

TLDR
Results where infection of larval yellow fever mosquitoes Aedes aegypti with the microsporidian Edhazardia aedis was experimentally manipulated allowed comparisons between estimates of horizontal and vertical transmission on host fitness, and the measure of virulence was the fluctuating asymmetry of adult female wings.
Ectoparasite virulence is linked to mode of transmission

TLDR
Compared the virulence of lice and mites infesting a single group of captive rock doves, results support the hypothesis that ectoparasite virulence is linked to the mode of transmission.
Vertical transmission and evolution of mutualism from parasitism
Abstract Using an evolutionarily stable strategy (ESS) model, it is shown that vertical transmission, defined as the direct transfer of infection from a parent host to its progeny, is an important
Trade‐off between Virulence and Vertical Transmission and the Maintenance of a Virulent Plant Pathogen
TLDR
A trade‐off between virulence and vertical transmission is demonstrated, explaining the maintenance of more virulent, completely castrating fungal genotypes in natural populations, and suggest that vertical transmission in plants is more complex than what is considered in current models.
SELECTION OF BENEVOLENCE IN A HOST–PARASITE SYSTEM
TLDR
When cells harboring different variants of these phage were cultured so that no infectious spread was allowed, ensuring that all parasite transmission was vertical, selection favored the variants that were most benevolent to the host—those that least harmed host growth rate.
The population dynamics of vertically and horizontally transmitted parasites
We analyse a model of the transmission dynamics of a parasite transmitted both vertically and horizontally. The basic reproductive ratio (R0) of the parasite is shown to be a sum of horizontal and
Populations and infectious diseases: Dynamics and evolution
TLDR
The host-parasite or host-pathogen system was analyzed from dynamical and evolutionary viewpoints using simple mathematical models incorporating vertical transmission, immunity and its loss and it was found that only reduction in additional mortality due to infection was the evolutionary trend common to both host and pathogen.
Host-Parasite Relations, Vectors, and the Evolution of Disease Severity
A widespread contention in the parasitological and medical literature is that severe disease represents a lack of coadaption between host and parasite2 because parasite species that do not harm their
Sex versus non-sex versus parasite
TLDR
It is shown that with frequency dependence sufficiently intense such models generate cycles, and that in certain states of cycling sexual species easily obtain higher long-term geometric mean fitness than any competing monotypic asexual species or mixture of such.
