Host defense triggers rapid adaptive radiation in experimentally evolving parasites.

Evol Lett 2019 Apr 5;3(2):120-128. Epub 2019 Mar 5.

School of Biological Sciences University of Utah Salt Lake City Utah 84112.

Adaptive radiation occurs when the members of a single lineage evolve different adaptive forms in response to selection imposed by competitors or predators. Iconic examples include Darwin's finches, Caribbean anoles, and Hawaiian silverswords, all of which live on islands. Although adaptive radiation is thought to be an important generator of biodiversity, most studies concern groups that have already diversified. Read More

Synergistic osmoregulatory dysfunction during salmon lice (Lepeophtheirus salmonis) and infectious hematopoietic necrosis virus co-infection in sockeye salmon (Oncorhynchus nerka) smolts.

J Fish Dis 2019 Apr 12. Epub 2019 Apr 12.

Fisheries and Ocean Canada, Pacific Biological Station, Nanaimo, British Columbia, Canada.

While co-infections are common in both wild and cultured fish, knowledge of the interactive effects of multiple pathogens on host physiology, gene expression and immune response is limited. To evaluate the impact of co-infection on host survival, physiology and gene expression, sockeye salmon Oncorhynchus nerka smolts were infected with the salmon louse Lepeophtheirus salmonis (V-/SL+), infectious hematopoietic necrosis virus (IHNV; V+/SL-), both (V+/SL+), or neither (V-/SL-).

Plumage brightness and uropygial gland secretions in barn swallows.

Curr Zool 2019 Apr 31;65(2):177-182. Epub 2018 May 31.

Department of Ecology and Genetics, Evolutionary Biology Centre, University of Uppsala, Norbyvägen 18d, SE, Uppsala, Sweden.

The uropygial gland has been hypothesized to play a role in sexual signaling through a "make-up" function derived from the effects of secretions from the gland on the appearance of the plumage and bare parts of the body. Here we show that plumage brightness of dorsal feathers of individual barn swallows was greater in mated than in unmated individuals. In addition, plumage brightness increased with colony size.

Ann Clin Transl Neurol 2019 Mar 25;6(3):475-485. Epub 2019 Feb 25.

IRCCS Istituto delle Scienze Neurologiche di Bologna Bologna Italy.

Objective: We investigated the contribution to sporadic focal epilepsies (FE) of ultrarare variants in genes coding for the components of complexes regulating mechanistic Target Of Rapamycin (mTOR)complex 1 (mTORC1).

Methods: We collected genetic data of 121 Italian isolated FE cases and 512 controls by Whole Exome Sequencing (WES) and single-molecule Molecular Inversion Probes (smMIPs) targeting 10 genes of the GATOR1, GATOR2, and TSC complexes. We collapsed "qualifying" variants (ultrarare and predicted to be deleterious or loss of function) across the examined genes and sought to identify their enrichment in cases compared to controls.

Louse-borne relapsing fever (Borrelia recurrentis infection).

Authors:
David A Warrell

Epidemiol Infect 2019 Jan;147:e106

Nuffield Department of Clinical Medicine,University of Oxford,Oxford,UK.

Louse-borne relapsing fever (LBRF) is an epidemic disease with a fascinating history from Hippocrates' times, through the 6th century 'Yellow Plague', to epidemics in Ireland, Scotland and England in the 19th century and two large Afro-Middle Eastern pandemics in the 20th century. An endemic focus persists in Ethiopia and adjacent territories in the Horn of Africa. Since 2015, awareness of LBRF in Europe, as a re-emerging disease, has been increased dramatically by the discovery of this infection in dozens of refugees arriving from Africa. Read More

Antarctophthirus microchir infestation in synanthropic South American sea lion (Otaria flavescens) males diagnosed by a novel non-invasive method.

Parasitol Res 2019 Mar 14. Epub 2019 Mar 14.

Institute of Parasitology, Biomedical Research Center Seltersberg (BFS), Justus Liebig University Giessen, Schubertstr. 81, 35392, Giessen, Germany.

Antarctophthirus microchir is a sucking louse species belonging to the family Echinophthiriidae and has been reported to parasitize all species of the subfamily Otariinae, the sea lions. Former studies on this ectoparasite mainly required fixation, immobilization, or death of host species and especially examinations of adult male sea lions are still very rare. Between March and May 2018, adult individuals of a unique "urban" bachelor group of South American sea lions (Otaria flavescens) living directly in the city of Valdivia, Chile, were studied regarding their ectoparasite infestation status.

A scavenger receptor B (CD36)-like protein is a potential mediator of intestinal heme absorption in the hematophagous ectoparasite Lepeophtheirus salmonis.

Sci Rep 2019 Mar 12;9(1):4218. Epub 2019 Mar 12.

Department of Informatics & Sea Lice Research Centre (SLRC), University of Bergen, Bergen, Norway.

Intestinal absorption of heme has remained enigmatic for years, even though heme provides the most bioavailable form of iron. The salmon louse, Lepeophtheirus salmonis, is a heme auxotrophic ectoparasite feeding on large quantities of blood from its host, the salmon. Here we show that a scavenging CD36-like receptor is a potential mediator of heme absorption in the intestine of the salmon louse. Read More

Discovery and Functional Annotation of Quantitative Trait Loci Affecting Resistance to Sea Lice in Atlantic Salmon.

Front Genet 2019 8;10:56. Epub 2019 Feb 8.

Facultad de Ciencias Veterinarias y Pecuarias, Universidad de Chile, Santiago, Chile.

Sea lice () are ectoparasitic copepods which have a large negative economic and welfare impact in Atlantic salmon () aquaculture, particularly in Chile. A multi-faceted prevention and control strategy is required to tackle lice, and selective breeding contributes via cumulative improvement of host resistance to the parasite. While host resistance has been shown to be heritable, little is yet known about the individual loci that contribute to this resistance, the potential underlying genes, and their mechanisms of action.

Institute of Marine Research, Austevoll Research Station, Saugeneset 16, 5392 Storebø, Norway. Electronic address:

Chemoreception is critical for marine ectoparasites - such as salmon lice (Lepeophtheirus salmonis) - to identify and locate salmonid hosts. The molecular receptors that parasites employ to detect host-specific chemical stimuli from hosts (kairomones) have not been well characterised. In the present study, transcription of the sea louse Ionotropic receptor 25a (IR25a) was blocked to evaluate whether it functions as a chemical-perception related gene for a specific chemical cue from the Atlantic salmon host.

Identifying 'firebreaks' to fragment dispersal networks of a marine parasite.

Int J Parasitol 2019 Mar 17;49(3-4):277-286. Epub 2019 Jan 17.

School of BioSciences, University of Melbourne, 3010 Victoria, Australia.

Marine ecosystems are beset by disease outbreaks, and efficient strategies to control dispersal of pathogens are scarce. We tested whether introducing no-farming areas or 'firebreaks' could disconnect dispersal networks of a parasitic disease affecting the world's largest marine fish farming industry (∼1000 farms). Larval salmon lice (Lepeophtheirus salmonis) are released from and transported among salmon farms by ocean currents, creating inter-farm networks of louse dispersal. Read More

NASN Special Interest Groups: Their Growth and Development Through the Years.

NASN Sch Nurse 2019 Mar 18;34(2):118-123. Epub 2019 Jan 18.

Co-Chair, School Nurse Administrator Special Interest Group, Cedar Rapids, IA.

Over the past 25 years, the roles of school nurses have been both expanding and specializing in public and non-public school settings. To help meet the ever-changing and demanding challenges that specialized school nurses encounter in their unique settings, NASN embraced the idea that school nurses need a way to connect with colleagues working in similar practices. Thus, special interest groups (SIGs) were established, and the SIGs have become an integral part of NASN. Read More

Sea lice, Lepeophtheirus salmonis (Krøyer 1837), infected Atlantic salmon (Salmo salar L.) are more susceptible to infectious salmon anemia virus.

PLoS One 2019 16;14(1):e0209178. Epub 2019 Jan 16.

Aquaculture Research Institute, University of Maine, Hitchner Hall, Orono, Maine, United States of America.

The role of parasitic sea lice (Siphonostomatoida; Caligidae), especially Lepeophtheirus salmonis, in the epidemiology of Infectious Salmon Anemia Virus (ISAv) has long been suspected. The epidemiological studies conducted during the 1998 major Infectious Salmon Anaemia (ISA) outbreak in Scotland demonstrated a strong correlation between sea lice presence and ISAv positive sites or subsequent clinical outbreaks of ISA. The question posed from this observation was "do sea lice infestations on Atlantic salmon make them more susceptible to viral infections?" This study investigated the role that sea lice infestations have on the severity of ISAv infections and disease mortality in experimental populations of farmed Atlantic salmon (Salmo salar).

Dynamics of Caligus rogercresseyi (Boxshall & Bravo, 2000) in farmed Atlantic salmon (Salmo salar) in southern Chile: Are we controlling sea lice?

J Fish Dis 2019 Mar 15;42(3):357-369. Epub 2019 Jan 15.

Institute of Aquaculture, Universidad Austral de Chile, Puerto Montt, Chile.

Caligus rogercresseyi generates the greatest losses in the salmon industry in Chile. The relationship between salmon farming and sea lice is made up of various components: the parasite, host, environment and farming practices, which make it difficult to identify patterns in parasite population dynamics to define prevention and control strategies. The objectives of this study were to analyse and compare the effect of farming, sanitary practices and environmental variables on the abundance of gravid females (GF) and juveniles (JUV) of C.

Horizontal and vertical exploration in woodlice: A dual-process model.

Authors:
Patrick Anselme

Behav Processes 2019 Feb 31;159:55-56. Epub 2018 Dec 31.

Faculty of Psychology, Department of Biopsychology, University of Bochum, Universitätsstraße 150, D-44801, Bochum, Germany. Electronic address:

Woodlice placed in an unknown experimental enclosure typically run (horizontal exploration) and rear up on the enclosure's walls (vertical exploration). Previous findings with Porcellio scaber indicate that these two behaviors have an opposite temporal distribution and show differential sensitivity to rotation-induced physiological stress. It is argued that the dual-process theory of habituation and sensitization can serve as a basis to account for horizontal and vertical exploratory activities in woodlice. Read More

Loss of genetic diversity, recovery and allele surfing in a colonizing parasite, Geomydoecus aurei.

Mol Ecol 2019 Feb 21;28(4):703-720. Epub 2019 Feb 21.

Department of Biology, University of Northern Iowa, Cedar Falls, Iowa.

Understanding the genetic consequences of changes in species distributions has wide-ranging implications for predicting future outcomes of climate change, for protecting threatened or endangered populations and for understanding the history that has led to current genetic patterns within species. Herein, we examine the genetic consequences of range expansion over a 25-year period in a parasite (Geomydoecus aurei) that is in the process of expanding its geographic range via invasion of a novel host. By sampling the genetics of 1,935 G. Read More

Warm water hazard: Sea lice and seabather's eruption.

Nursing 2019 Jan;49(1):40-43

Myles Thomas Quail is an RN for surveillance at the Massachusetts Bureau of Environmental Health in Boston, Mass.

Nurses may see patients who have recently returned from tropical vacations complaining of a severe pruritic dermatitis known as seabather's eruption (SBE). Caused by exposure to jellyfish larvae, SBE is characterized by a pruritic rash, but some patients, particularly children, experience systemic signs and symptoms such as fever, chills, and nausea/vomiting. This article discusses SBE and reviews assessment tips, nursing care, and patient teaching. Read More
