Offsetting the Cost of Parasitism Fruit flies, like most animals, are vulnerable to infection by a range of organisms, which, in co-infections, can interact with sometimes surprising effects. Jaenike et al. (p. 212) discovered that a species of Spiroplasma bacterium that is sometimes found in flies, and that is transmitted from mother to offspring, protects its host from the effects of a nematode worm parasite, Howardula aoronymphium. The worm sterilizes the female flies and shortens their… Expand
Ecology of a novel defensive symbiont of Drosophila: Spiroplasma-mediated protection against parasitic nematodes
TLDR
This thesis found that D. neotestacea harbours a strain of the bacterial symbiont Spiroplasma that restores fertility to nematode-parasitized female flies, and Sequencing a number of Spiro Plasma genes, as well as fly mitochondrial DNA, strongly suggests that the defensive symbionts is spreading westward.

Host Defense via Symbiosis in Drosophila
TLDR
What is known of Drosophila as an intriguing and emerging model of defensive symbiosis is summarized to shift the perception of many facultative inherited symbionts from that of manipulative parasites toward helpful mutualists. Expand
Endosymbiont-based immunity in Drosophila melanogaster against parasitic nematode infection
TLDR
An interaction between Wolbachia endosymbionts with the immune response of D. melanogaster against infection with the entomopathogenic nematodes is suggested and indicates a complex interplay between insect hosts, endosYmbiotic microbes and pathogenic organisms. Expand
A ribosome-inactivating protein in a Drosophila defensive symbiont
TLDR
This study identifies a novel RIP in an insect defensive symbiont and suggests an underlying RIP-dependent mechanism in Spiroplasma-mediated defense. Expand
Male killing Spiroplasma protects Drosophila melanogaster against two parasitoid wasps
TLDR
The results indicate that Spiroplasma MSRO prevents successful development of both wasps, and confers a small, albeit significant, increase in larva-to-adult survival of flies subjected to wasp attacks, and the conditions under which defense can contribute to Spiro Plasma persistence are modeled. Expand
No evidence for behavioural adaptations to nematode parasitism by the fly Drosophila putrida
TLDR
There are no direct effects of eating α‐amanitin on this host–parasite interaction, and it is suggested that toxin tolerance is more likely maintained by selection due to competition for resources than as a mechanism to avoid parasite infection or to reduce the virulence of infection. Expand
Rapid spread of the defensive endosymbiont Spiroplasma in Drosophila hydei under high parasitoid wasp pressure.
TLDR
The defensive mechanism may contribute to the high prevalence of Spiroplasma in host populations despite imperfect vertical transmission, and any possible fitness costs to harboring Spiraplasma are addressed. Expand
Defensive endosymbionts: a cryptic trophic level in community ecology.
TLDR
It is shown that Spiroplasma spreads rapidly within experimental populations of D. neotestacea subject to Howardula parasitism, but is neither strongly favored nor selected against in the absence of Howardula, exhibiting effectively consumer-resource trophic dynamics. Expand
Toxin and Genome Evolution in a Drosophila Defensive Symbiosis
TLDR
The results suggest that distantly related Spiroplasma RIP toxins may perform specialized functions with regard to parasite specificity and suggest an important role for horizontal gene transfer in the emergence of novel defensive phenotypes. Expand
Functional analysis of RIP toxins from the Drosophila endosymbiont Spiroplasma poulsonii
TLDR
The results indicate that RIPs released by S. poulsonii contribute to the reduction of host lifespan and embryo mortality, which suggests that SpRIPs may impact the insect-symbiont homeostasis beyond their protective function against parasites. Expand

The Bacterial Symbiont Wolbachia Induces Resistance to RNA Viral Infections in Drosophila melanogaster
TLDR
It is reported that a bacterial infection renders D. melanogaster more resistant to Drosophila C virus, reducing the load of viruses in infected flies and identifying these resistance-inducing bacteria as Wolbachia. Expand
EVOLUTION OF MULTIPLE COMPONENTS OF VIRULENCE IN DROSOPHILA‐NEMATODE ASSOCIATIONS
TLDR
Virulence is evolutionarily labile in associations between Drosophila testacea group species and their Howardula parasites, and changes in the sterility component of virulence are due primarily to host evolution, whereasChanges in the host mortality component are due in large part to parasite evolution.

TLDR
Field and laboratory evidence shows that the nematode parasite Howardula aoronymphium is relatively avirulent to one of its principal host species, Drosophila falleni, whereas it is much more virulent to D. putrida and D. neotestacea, suggesting that there may be substantial vertical transmission in D. falleni.

Evolutionarily stable infection by a male-killing endosymbiont in Drosophila innubila: molecular evidence from the host and parasite genomes.
TLDR
Molecular data suggest that this male-killing strain of Wolbachia discovered in natural populations of D. innubila is evolutionarily old, a conclusion supported with a simple model of parasite and mtDNA transmission dynamics. Expand
Associations between mycophagous Drosophila and their Howardula nematode parasites: a worldwide phylogenetic shuffle
TLDR
Overall, these host associations are highly dynamic, and appear to be driven by a combination of repeated opportunities for host colonization due to shared breeding sites and large potential host ranges of the nematodes. Expand
Facultative bacterial symbionts in aphids confer resistance to parasitic wasps
TLDR
Investigation of aphids for vulnerability of the aphid host to a hymenopteran parasitoid, Aphidius ervi, shows that infection confers resistance to parasitoids attack by causing high mortality of developing Parasitoid larvae. Expand
Ecology and Evolution of Host‐Parasite Associations: Mycophagous Drosophila and Their Parasitic Nematodes
TLDR
A biogeographic analysis of the relative abundance of different Drosophila species has shown that H. aoronymphium may facilitate the coexistence of different species of Drosophile that compete for larval food resources. Expand
Multiple introductions of the Spiroplasma bacterial endosymbiont into Drosophila
TLDR
A multilocus sequence analysis is used to reconstruct a robust Spiroplasma endosymbiont phylogeny, assess genetic diversity, and look for evidence of recombination in Drosophila populations. Expand
Heritable Endosymbionts of Drosophila
TLDR
Findings indicate that in contrast to some other insect groups, other heritable symbionts are uncommon in Drosophila species, possibly reflecting a robust innate immune response that eliminates many bacteria. Expand

TLDR
The results show that these mobile genetic elements can endow a bacterial symbiont with benefits that extend to the animal host, and that phages vector ecologically important traits, such as defense against parasitoids, within and among Symbiont and animal host lineages. Expand
