Part II – Ectoparasites: Pediculosis and Tungiasis

Pediculosis is an infestation of lice on the body, head, and/or pubic region that occurs worldwide. Lice are ectoparasites of the order Phthiraptera that feed on the blood of infested hosts. Their morphotype dictates their clinical features. Body lice may transmit bacterial pathogens that cause trench fever, relapsing fever, and epidemic typhus, which are potentially life-threatening diseases that remain relevant in contemporary times. Recent data from some settings suggest head lice may harbor pathogens.

In this study, ectoparasitic insect fauna of rodents found across the Iran were studied, to generate an annotated checklist of fleas and lice species. Methods: Several field expeditions focused on different habitats of northeastern Iran were conducted between January 2017 and May 2018. Rodent trapping was carried out using custom-made mesh live traps and "Faragir" live traps baited mainly with scorched sunflower and gourd seeds. The trapped rodents were examined for ectoparasites on their body, and then released at their trapping point. The rodents and ectoparasite species were identified based on available k...

Drones transporting sterilized male mosquitos, cybernetic dragonflies, genetically modified insects with malaria-resisting traits, supersensitive radars or digital maps: the most innovative methods are deployed in the war on the tiniest but most murderous beasts out there: mosquitos, fleas, ticks carrying infectious diseases. Here’s the latest arsenal of digital technologies to eradicate insects and reduce deadly epidemics. Unusual suspects: mosquitos, fleas, and ticks Sharks, bears, tigers, the Killer Rabbit of Caerbannog in association with sharp teeth and claws represent the traditional image of deadly animals. Ho...

CONCLUSION: When management is optimized, the economic value increases with decreasing values of [Formula: see text] (until the threshold of [Formula: see text], where it drops to zero). When management is not optimized, the economic value depends on whether genetic improvement is used for reduced expenditures or production losses. For sea lice in salmon, the economic value is estimated to be 0.065 €/unit [Formula: see text]/kg production. PMID: 30285629 [PubMed - in process]

Publication date: Available online 18 August 2018Source: EpidemicsAuthor(s): Aldrin M., Jansen P.A., Stryhn H.AbstractThe parasitic salmon louse constrains growth in the Norwegian salmon farming industry through density dependent host-parasite interaction. Hence, there is a need for insight into how increases in salmon production, varying spatial organisation of the production and pest control strategies affect salmon louse population dynamics. Here we present a new salmon louse model for exploring effects of varying salmon farming conditions on spatio-temporal abundances of the parasite. The salmon louse model is partly s...

The head lice, Pediculus humanus capitis, are obligate blood-sucking parasites that live exclusively in the scalp region of humans [1,2]. They represent one of the most prevalent parasitic infestation with major economic and social concerns throughout the world [3]. Body lice are the main vectors of at least three human pathogens: Rickettsia prowazekii, the agent of epidemic typhus, Bartonella quintana the agent of trench fever, and Borrelia recurrentis that of relapsing fever. Currently, head lice are not considered to be vectors for human pathogens.

In this study, two sets of multivariate autoregressive state-space models were applied to Chilean sea lice data from six Atlantic salmon production cycles on five isolated farms (at least 20 km seaway distance away from other known active farms), to evaluate the utility of these models for predicting sea lice abundance over time on farms. The models were constructed with different parameter configurations, and the analysis demonstrated large heterogeneity between production cycles for the autoregressive parameter, the effects of chemotherapeutant bath treatments, and the process-error variance. A model allowing for diffe...
