Despite the impor- tance of Drosophila melanogaster as a model of infection and immunity and a long awareness that trypanosomatid infection is common in the genus, no trypanosomatid parasites naturally infecting Drosophila have been characterized. Here, we establish a new model of trypanosomatid infection in Drosophila—Jaenimonas drosophilae, gen. et sp. nov. As far as we are aware, this is the first Drosophila-parasitic trypanosomatid to be cultured and characterized. Through experimental infections, we find that Drosophila falleni, the natural host, is highly susceptible to infection, leading to a substantial decrease in host fecundity. J. droso- mbio.asm.org philae has a broad host range, readily infecting a number of Drosophila species, including D.

ADAMS,ScottM.PEAT and Adler R. DILLMAN Microbiology & Molecular Biology Department, and Evolutionary Ecology Laboratory, Brigham Young University, Provo, UT 84602-5253, USA Introduction Nematodes originated during the Precambrian explosion over 500 million years ago (Wray et al., 1996; Ayala & Rzhetsky, 1998; Rod- riguez-Trelles et al., 2002). The phylogenetic position of the Nematoda relative to other metazoans has historically been one of contention. Originally circumscribed within the Vermes Linnaeus, 1758 and later the Aschelminthes Grobben, 1910 (Claus & Grobben, 1910), the Nematoda are now believed to belong to a clade of moulting animals, the Ecdysozoa (Aguinaldo et al., 1997), and share a most recent common ancestor with arthropods, kinorhynchs, nematomorphs, onychophorans, priapulids and tardigrades. ORIGINS OF ENTOMOPATHOGENIC NEMATODES (EPN) Entomopathogenic nematodes of the Steinernematidae and Het- erorhabditidae are not monophyletic, but likely began independently to explore biotic relationships with arthropods and Gram-negative enteric bacteria (Enterobacteriaceae) by the mid-Palaeozoic (approximately 350 million years ago) (Poinar, 1993). Their origins were probably not syn- chronous and the ages of their respective lineages appear to be signif- icantly different. Evidence for the disparate origins and relative age of these Families is illustrated in Figure 240. Assuming even a somewhat sloppy molecular clock, the long branch lengths of Steinernema, both within the genus and relative to its most recent common ancestor, imply that it has been evolving independently of other nematode lineages for a longer period of time than Heterorhabditis.

  • Nematoda: Tylenchida: Allantonematidae)1 Danielle Sprague and Joe Funderburk2
    EENY681 Entomopathogenic Nematodes of Thrips Thripinema spp. (Nematoda: Tylenchida: Allantonematidae)1 Danielle Sprague and Joe Funderburk2 Introduction Several species of entomopathogenic nematodes in the genus Thripinema are known to naturally parasitize thrips (Thysanoptera). Thripinema fuscum Tipping and Nguyen is the most common species in Florida (Figure 1). Thripinema fuscum is economically important because it is a natural enemy of the insect pest, the tobacco thrips, Frankliniella fusca (Hinds). Taxonomy The first observation of parasitic nematodes of thrips was made by Uzel (1895) in Europe when an unnamed nema- tode was reported in the body cavity of Thrips physapus L. A nematode inhabiting bean thrips, Heliothrips fasciatus L., was reported in California by Russell (1912), but not described. The first description of parasitic nematodes of thrips was not made until 1932 by Sharga, who described the Figure 1. Thripinema fuscum, female. A) Infective female. B) Anterior nematode Tylenchus aptini from Aptinothrips rufus Gmelin region of infective female. C, D, F) Progressive enlargement of parasitic in England. Following that, Lysaught (1936) proposed the female. E) Gonad of infective female. Photograph from Tipping C, name Anguillulina aptini for this species (Tipping 1998).

A major challenge in the study of Less studied are young obligate symbioses in host lineages that obligate symbioses is to understand how they arise. Because the did not already house obligate symbionts (i.e., “symbiont-naive” best studied obligate symbioses are ancient, it is especially chal- hosts) (10). Some of the best known examples originate through lenging to identify early or intermediate stages. Here we report host manipulation by the symbiont via addiction or reproductive the discovery of a nascent obligate symbiosis in Howardula aor- control. Addiction or dependence may be a common route for onymphium, a well-studied nematode parasite of Drosophila flies.

  • A Ribosome-Inactivating Protein in a Drosophila Defensive Symbiont
    A ribosome-inactivating protein in a Drosophila defensive symbiont Phineas T. Hamiltona,1, Fangni Pengb, Martin J. Boulangerb, and Steve J.

Moran, University of Texas at Austin, Austin, TX, and approved November 24, 2015 (received for review September 18, 2015) Vertically transmitted symbionts that protect their hosts against the proximate causes of defense are largely unknown, although parasites and pathogens are well known from insects, yet the recent studies have provided some intriguing early insights: A underlying mechanisms of symbiont-mediated defense are largely Pseudomonas symbiont of rove beetles produces a polyketide unclear. A striking example of an ecologically important defensive toxin thought to deter predation by spiders (14), Streptomyces symbiosis involves the woodland fly Drosophila neotestacea, symbionts of beewolves produce antibiotics to protect the host which is protected by the bacterial endosymbiont Spiroplasma from fungal infection (17), and bacteriophages encoding putative when parasitized by the nematode Howardula aoronymphium. toxins are required for Hamiltonella defensa to protect its aphid The benefit of this defense strategy has led to the rapid spread host from parasitic wasps (18),

  • Nematodes of the Order Tylenchida in Germany – the Non-Phytoparasitic Species
    88 (1) · April 2016 pp. 19–41 Nematodes of the order Tylenchida in Germany – the non-phytoparasitic species Dieter Sturhan1* and Karin Hohberg² 1 Arnethstr. 13D, 48159 Münster, Germany and c/o Julius Kühn-Institut, Toppheideweg 88, 48161 Münster, Germany ² Senckenberg Museum of Natural History Görlitz, Am Museum 1, 02826 Görlitz, Germany * Corresponding author, e-mail: [email protected] Received 15 February 2016 | Accepted 30 March 2016 Published online at www.soil-organisms.de 1 April 2016 | Printed version 15 April 2016 Abstract In the recently published checklist of plant-parasitic nematodes known from Germany (Sturhan 2014) genera and species of the order Tylenchida, which are generally considered as being parasites of higher plants, represent the largest taxonomic group with 212 species. The present paper gives an overview of the remaining trophic groups in Tylenchida: Root tip feeders, myceliophagous species and entomoparasites, the latter often having a free-living soil generation. A total of 165 species are included, most of them representatives of the suborder Hexatylina (96 species), followed by members of Tylenchina (67 species). Where available, first records for Germany are given together with data on habitat, distribution and the hosts of zooparasitic species. A high number of valid species (95) were originally described from Germany; 20 additional species have been synonymised with previously described species or are considered as species inquirendae. Published data are critically reviewed and some new records are added. Many published records are considered as questionable and need verification. Part of the species is deficiently characterised and requires further study. The number of unidentified and still undescribed species appears to be high.

  • Transcriptomic Insights Into the Insect Immune Response to Nematode Infection
    G C A T T A C G G C A T genes Review Transcriptomic Insights into the Insect Immune Response to Nematode Infection Ioannis Eleftherianos * and Christa Heryanto Infection and Innate Immunity Lab, Department of Biological Sciences, Institute for Biomedical Sciences, The George Washington University, Washington, DC 20052, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-202-994-2367 Abstract: Insects in nature interact with a wide variety of microbial enemies including nematodes. These include entomopathogenic nematodes that contain mutualistic bacteria and together are able to infect a broad range of insects in order to complete their life cycle and multiply, filarial nematodes which are vectored by mosquitoes, and other parasitic nematodes. Entomopathogenic nematodes are commonly used in biological control practices and they form excellent research tools for understanding the genetic and functional bases of nematode pathogenicity and insect anti-nematode immunity. In addition, clarifying the mechanism of transmission of filarial nematodes by mosquitoes is critical for devising strategies to reduce disease transmission in humans. In all cases and in order to achieve these goals, it is vital to determine the number and type of insect host genes which are differentially regulated during infection and encode factors with anti-nematode properties. In this respect, the use of transcriptomic approaches has proven a key step for the identification of insect molecules with anti-nematode activity. Here, we review the progress in the field of transcriptomics that deals with the insect response to nematode infection. This information is important because it will expose conserved pathways of anti-nematode immunity in humans.
