"A cleaner break": Genetic divergence between geographic groups and sympatric phenotypes revealed in ballan wrasse ().

Ecol Evol 2020 Jun 5;10(12):6120-6135. Epub 2020 Jun 5.

Institute of Marine Research Bergen Norway.

Capture and long-distance translocation of cleaner fish to control lice infestations on marine salmonid farms has the potential to influence wild populations via overexploitation in source regions, and introgression in recipient regions. Knowledge of population genetic structure is therefore required. We studied the genetic structure of ballan wrasse, a phenotypically diverse and extensively used cleaner fish, from 18 locations in Norway and Sweden, and from Galicia, Spain, using 82 SNP markers.

Salmon lice survive the straight shooter: A commercial scale sea cage trial of laser delousing.

Prev Vet Med 2020 Jun 18;181:105063. Epub 2020 Jun 18.

Sustainable Aquaculture Laboratory - Temperate and Tropical (SALTT), School of BioSciences, University of Melbourne, Victoria 3010, Australia.

Ectoparasitic salmon louse (Lepeophtheirus salmonis) infestations are costly for Atlantic salmon (Salmo salar) farmers in Norway. As a result, there is a strong desire for solutions to prevent and control infestations, and new technologies are typically developed and commercialised rapidly, without rigorous validation. Here, we tested the efficacy of a new commercially available control measure-delousing by underwater lasers-using a replicated design at full commercial scale. Read More

Vaccuuming method as a successful strategy in the diagnosis of active infestation by Pediculus humanus capitis.

Rev Inst Med Trop Sao Paulo 2020 7;62:e7. Epub 2020 Feb 7.

Universidade Federal do Paraná, Departamento de Patologia Básica, Curitiba, Paraná, Brazil.

Most human epidemiological and clinical studies use visual inspection of the hair and scalp to diagnose Pediculus humanus capitis , however this method has low sensitivity to diagnose active infestations (presence of nymphs and adult lice). Vacuuming the hair and scalp has been used as a diagnostic method, but there are no previous data comparing its effectiveness with visual inspection. The aim of this study was to determine the prevalence of overall infestation (nits and trophic stages), of active infestation by Pediculus humanus capitis , and to evaluate the effectiveness of vacuuming in comparison with the visual inspection.

Extensive host-switching of avian feather lice following the Cretaceous-Paleogene mass extinction event.

Commun Biol 2019 29;2:445. Epub 2019 Nov 29.

Illinois Natural History Survey, Prairie Research Institute, University of Illinois, Champaign, IL USA.

Nearly all lineages of birds host parasitic feather lice. Based on recent phylogenomic studies, the three major lineages of modern birds diverged from each other before the Cretaceous-Paleogene (K-Pg) mass extinction event. In contrast, studies of the phylogeny of feather lice on birds, indicate that these parasites diversified largely after this event. Read More

Combined treatment modality for phthiriasis palpebrarum.

Indian J Med Microbiol 2019 Apr-Jun;37(2):296-297

Department of Post Graduate Ophthalmology, Aravind Eye Hospital, Madurai, Tamil Nadu, India.

Phthiriasis palpebrarum (PP) is the infestation of eyelids caused by the ectoparasite Phthirus pubis, frequently misdiagnosed as allergic conjunctivitis, blepharitis or dermatitis. There is no standard treatment of choice although various treatment modalities have been described. A 6-year-old male child with PP was successfully treated with local application of 20% fluorescein solution over the eyelashes and eyebrows of both the eyes, followed by the mechanical removal of all parasites and trimming of the eyelashes from the base and application of ophthalmic ointment.

Effects of laboratory salmon louse infection on Arctic char osmoregulation, growth and survival.

Conserv Physiol 2019 7;7(1):coz072. Epub 2019 Nov 7.

Department of Primary Industries, Narrandera Fisheries Centre, PO Box 182, Narrandera, New South Wales, Australia.

High salmon lice () infestation levels resulting from intensive salmonid sea-cage aquaculture can threaten populations of wild salmonid hosts. This includes anadromous Arctic char (), which rely on short migrations into more productive seawater environments to build energy stores for maturation, spawning and over-wintering in freshwater. Elevated salmon lice burdens may limit the benefits of migration by constraining osmoregulation, growth, survival and reproduction. Read More

Systematic Entomology, Graduate School of Agriculture, Hokkaido University, Sapporo, 060-8589, Japan..

Three species of chewing lice-Eucolpocephalum femorale (Piaget, 1880) (Amblycera: Menoponidae), Ibidoecus plataleae (Denny, 1842) (Ischnocera: Philopteridae) and Ardeicola plataleae (Linnaeus, 1758) (Ischnocera: Philopteridae)-are reported from the black-faced spoonbill (Platalea minor Temminck Schlegel, 1849) in Japan. These three louse species are new records for this host. The black-faced spoonbill is classified as a "Critically Endangered" species in the IUCN Red List; although its species of lice are known to infest other species of spoonbills, these lice are endangered at the population level.
