A Rare Case of Anemia Secondary to Lice Infestation

Cureus, 2022
Lice are parasitic infections that can infect humans and survive by consuming host blood. They are most commonly associated with a lack of hygiene and occur most commonly in school-age children, homeless populations, and densely populated areas. Lice infections can potentially lead to vector-containing illness and are rarely complicated by acute blood ...

Salmon louse Lepeophtheirus salmonis predominates over Caligus elongatus on Atlantic salmon post-smolts in central and western Norway

Aquaculture Environment Interactions
Atlantic salmon Salmo salar are exposed to parasitic sea lice as they enter the marine environment, particularly in areas with high densities of open net-pen salmon farming, where infestations can reach harmful levels.

Of lice and math: using models to understand and control populations of head lice. [PDF]

PLoS ONE, 2011
In this paper we use detailed data about the biology of the head louse (pediculus humanus capitis) to build a model of the evolution of head lice colonies.

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, EarlyView.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

History of sexually transmitted infections among mpox cases in the 2022 outbreak in Spain

HIV Medicine, EarlyView.
Abstract Objective The aim was to describe the history of sexually transmitted infections (STIs) among adult mpox men cases and to analyse sociodemographic and epidemiological characteristics according to the presence or absence of any STI diagnosed 1 or 6 months previous to mpox diagnosis during the 2022 outbreak in Spain.

Genetic composition of facultatively anadromous brown trout Salmo trutta L. in a freshwater‐lake system

Journal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta) has adapted to a wide range of habitats and displays a variety of life‐history strategies. Being facultatively anadromous, populations without migration barriers to the sea consist of both resident and anadromous individuals in different proportions.

Sea Lice (Lepeophtheirus salmonis) Harbour Putative Fish Pathogens: Insights From Illumina and Nanopore Sequencing

Journal of Fish Diseases, EarlyView.
ABSTRACT Ectoparasites that penetrate host skin can act as biological or mechanical vectors for pathogens and, in some cases, serve as reservoirs. Crustacean ectoparasites of fish are potential vectors of pathogens, which is especially relevant for obligate pathogens (e.g., Aeromonas salmonicida) with limited seawater survival. Sea lice (Lepeophtheirus

Ocular Manifestations of Infectious Salmon Anaemia Virus Infection in Atlantic Salmon (Salmo salar)

Journal of Fish Diseases, EarlyView.
ABSTRACT Eyes are essential sensory organs needed by teleost Atlantic salmon for high visual acuity and survival in both the wild and in aquaculture settings. In this work, we assessed the ocular manifestations of Infectious Salmon Anaemia Virus (ISAV) infection in Atlantic salmon by a cohabitation‐mediated infection assay and histological and ...

Sea lice (Lepeophtheirus salmonis) infestations and the productivity of pink salmon (Oncorhynchus gorbuscha) in the Broughton Archipelago, British Columbia, Canada [PDF]

, 2011
The spread of salmon lice ( Lepeophtheirus salmonis ) from salmon farms may threaten some wild salmon populations. Infestations of wild juvenile pink salmon ( Oncorhynchus gorbuscha ) have been associated with high mortality and population decline ...
