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

Int J Parasitol 2019 Jan 17. 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

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).

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.

Despite the common association of human lice with abandoned or neglected people, no procedure to assess pediculosis, aimed to detect signs of neglect, exists. Investigating the two most common forms of head louse infestation, regular and severe, we define lice-markers of neglect and develop a protocol and survey form to record and assess pediculosis. The study of head lice from a deceased victim of neglect helped unravel time-length since death, frequency of exposure to neglect and the cause and circumstances related to the death. Read More

Genetic and phenotypic differentiation of lumpfish () across the North Atlantic: implications for conservation and aquaculture.

PeerJ 2018 20;6:e5974. Epub 2018 Nov 20.

Department of Biosciences, Centre for Sustainable Aquatic Research, Swansea University, Swansea, Wales, United Kingdom.

Demand for lumpfish () has increased exponentially over the last decade, both for their roe, which is used as a caviar substitute, and increasingly also as cleaner fish to control sea lice in salmon farming. The species is classified as Near Threatened by the IUCN and there are growing concerns that over-exploitation of wild stocks and translocation of hatchery-reared lumpfish may compromise the genetic diversity of native populations. We carried out a comparative analysis of genetic and phenotypic variation across the species' range to estimate the level of genetic and phenotypic differentiation, and determined patterns of gene flow at spatial scales relevant to management.

Parasitic sea louse infestations on wild sea trout: separating the roles of fish farms and temperature.

Parasit Vectors 2018 Nov 29;11(1):609. Epub 2018 Nov 29.

Department of Health Management, University of PEI, Charlottetown, PEI C1A 4P3, Canada.

Background: The causal relation between parasitic sea lice on fish farms and sea lice on wild fish is a controversial subject. A specific scientific debate has been whether the statistical association between infestation pressure (IP) from fish farms and the number of parasites observed on wild sea trout emerges purely because of a confounding and direct effect of temperature (T).

Methods: We studied the associations between louse infestation on wild sea trout, fish farm activity and temperature in an area that practices coordinated fallowing in Nordhordland, Norway. Read More

Phylogenomics and the evolution of hemipteroid insects.

Proc Natl Acad Sci U S A 2018 12 26;115(50):12775-12780. Epub 2018 Nov 26.

Systematic Entomology, Hokkaido University, Sapporo, 060-8589 Japan.

Hemipteroid insects (Paraneoptera), with over 10% of all known insect diversity, are a major component of terrestrial and aquatic ecosystems. Previous phylogenetic analyses have not consistently resolved the relationships among major hemipteroid lineages. We provide maximum likelihood-based phylogenomic analyses of a taxonomically comprehensive dataset comprising sequences of 2,395 single-copy, protein-coding genes for 193 samples of hemipteroid insects and outgroups.

Genetics and Genomics of an Unusual Selfish Sex Ratio Distortion in an Insect.

Curr Biol 2018 Dec 15;28(23):3864-3870.e4. Epub 2018 Nov 15.

Department of Biology, University of Victoria, Victoria, British Columbia, Canada. Electronic address:

Diverse selfish genetic elements have evolved the ability to manipulate reproduction to increase their transmission, and this can result in highly distorted sex ratios [1]. Indeed, one of the major explanations for why sex determination systems are so dynamic is because they are shaped by ongoing coevolutionary arms races between sex-ratio-distorting elements and the rest of the genome [2]. Here, we use genetic crosses and genome analysis to describe an unusual sex ratio distortion with striking consequences on genome organization in a booklouse species, Liposcelis sp. Read More

Characterization of tick organic anion transporting polypeptides (OATPs) upon bacterial and viral infections.

Parasit Vectors 2018 Nov 14;11(1):593. Epub 2018 Nov 14.

Department of Biological Sciences, Old Dominion University, Norfolk, VA, USA.

Background: Ixodes scapularis organic anion transporting polypeptides (OATPs) play important roles in tick-rickettsial pathogen interactions. In this report, we characterized the role of these conserved molecules in ticks infected with either Lyme disease agent Borrelia burgdorferi or tick-borne Langat virus (LGTV), a pathogen closely related to tick-borne encephalitis virus (TBEV).

Results: Quantitative real-time polymerase chain reaction analysis revealed no significant changes in oatps gene expression upon infection with B. Read More

The role of parasite dispersal in shaping a host-parasite system at multiple evolutionary scales.

Mol Ecol 2018 Dec 18;27(24):5104-5119. Epub 2018 Dec 18.

Illinois Natural History Survey, Prairie Research Institute, University of Illinois at Urbana-Champaign, Champaign, Illinois.

Parasite dispersal can shape host-parasite interactions at both deep and shallow timescales. One approach to understanding the effects of dispersal is to study parasite lineages that differ in dispersal capability but are from the same group of hosts. In this study, we compared phylogenetic and population genetic patterns of wing and body lice from ground-doves. Read More

The Use of Kernel Density Estimation With a Bio-Physical Model Provides a Method to Quantify Connectivity Among Salmon Farms: Spatial Planning and Management With Epidemiological Relevance.

Front Vet Sci 2018 30;5:269. Epub 2018 Oct 30.

Department of Health Management, Atlantic Veterinary College, University of Prince Edward Island, Charlottetown, PE, Canada.

Connectivity in an aquatic setting is determined by a combination of hydrodynamic circulation and the biology of the organisms driving linkages. These complex processes can be simulated in coupled biological-physical models. The physical model refers to an underlying circulation model defined by spatially-explicit nodes, often incorporating a particle-tracking model. Read More

Host specificity driving genetic structure and diversity in ectoparasite populations: Coevolutionary patterns in mice and their lice.

Ecol Evol 2018 Oct 3;8(20):10008-10022. Epub 2018 Oct 3.

Biology Centre CAS Institute of Parasitology České Budějovice Czech Republic.

A degree of host specificity, manifested by the processes of host-parasite cospeciations and host switches, is assumed to be a major determinant of parasites' evolution. To understand these patterns and formulate appropriate ecological hypotheses, we need better insight into the coevolutionary processes at the intraspecific level, including the maintenance of genetic diversity and population structure of parasites and their hosts. Here, we address these questions by analyzing large-scale molecular data on the louse and its hosts, mice of the genus , across a broad range of European localities. Read More

New records of chewing lice (Phthiraptera: Amblycera, Ischnocera) from Egyptian pigeons and doves (Columbiformes), with description of one new species.

Acta Trop 2019 Feb 29;190:22-27. Epub 2018 Oct 29.

Department of Entomology, Faculty of Science, Ain Shams University, Cairo, Egypt.

Little information is available about the chewing lice of wild birds of Egypt, including common groups such as pigeons and doves (Columbiformes). Through this work, parasitic chewing lice of common columbiformes of Egypt were revised including new data. Three species of pigeons and doves (Streptopelia decaocto Frivaldszky 1838, Spilopelia senegalensis Linnaeus 1766 and Columba livia Gmelin 1789) were examined for chewing lice at three different localities.
