Despite the economic importance of sea lice, comparatively little is known about the nature of their host-parasite relationship. The development of pesticide resistance in sea lice populations has been demonstrated for hydrogen peroxide and dichlorvos. To date only a small amount of work on bioactive molecules produced by fish lice has been undertaken. Few authors have looked at the antibody response of fish that are naturally infected with fish lice. We have, on the other hand, conclusive proof that lice are concerned in the transmission of the disease. The abundance of lice was lower in 2001. You yourself should know what difficulties lice provide aboard a ship and what a giant work is needed to get rid of them. One form is made up of asexually reproducing female lice which live permanently underground. The feather lice or biting lice found on birds cannot be combed out from their hosts, which is the method suggested for the previously-mentioned insects. Monkeys inoculated with the contents of lice, crushed on the 15th day after the infective feed, developed relapsing fever. The authors infected monkeys and mice with the spirochaetes obtained from human cases of relapsing fever, but failed to transmit infection by means of lice. How frequently do avian lice miss the boat ? Firstly, farmed lice are periodically or continuously exposed to pesticides. Rats, including the ears, were examined for ectoparasites (fleas, lice, mites and ticks) and collected by fine-toothcombing. 1.48) times more males than females were present in the lice samples. On one species of bird quite a number of lice of different genera and species can often be found. Molecular phylogenies and host-parasite cospeciation : gophers and lice a model system. Extensive damage is caused by skin-parasitizing parasitic copepods such as sea lice and these do elicit a stress response. Vertical transmission of the parasite may be facilitated by the relative timing of smolt migration and adult lice-infected salmon returning to the coast. Infection with 6 lice per fish caused skin infiltration by lymphocytes, also in areas without parasites. All phases of the life cycle of chewing lice take place on a host individual. She placed the body up outside as though it was looking at a returning hunter and put a mitt full of lice in the bed. Hopefully the rats have been taken care of but unfortunately the lice are still there. Not surprisingly, fewer males were found in 1999 when lice samples were mainly collected from 1 fish. At that time, the numbers of lice collected were under 100. The relative importance of innate and acquired immune responses in the relationship between fish lice and their hosts is not understood. More data on the cortisol levels in fish infested with sea lice are needed. With the exception of this study, there is little evidence for a protective specific immune response by fish against fish lice. Secondly, in lice populations generally, adaptation to different temperature regimes should occur. One of the most persistent allegations levelled at the evacuees had concerned the high incidence of head lice and skin disease. In the rat-trypanosome there occurs a contaminative infection through the dejecta of the fleas or lice which attack a fresh host. Typically, smolt populations are infested with a range of parasitic stages whereas adult salmon returning from the ocean tend to be infested with adult lice. Such an approach, using stress, offers a promising new direction to reveal the more subtle modulatory effects of parasitic lice. Capture and transfer of the fish was performed as quickly as possible to limit the number of escaping lice. Thereafter, sampling was carried out less often but over 1000 fish were examined when necessary to obtain one lice sample. Such spirochaetes are observable in lice up to the 11th day, and possibly longer. All adaptations facilitating the location of a fish host are of crucial importance for newly-hatched lice juveniles. Inside the house, everything was full of lice. The level of connectivity between patches therefore dictates whether a habitat patch (in the case of sea lice this is a single fish) is open or closed to outside recruitment. An examination of the lice removed from the boys showed 24 % of them to contain spirochaetes, whereas only 3°/o of the lice collected from the girls contained these microorganisms. Molecular phylogenies and hostparasite coevolution: gophers and lice as a model system. However, the broad range of antiparasite activity of ivermectin, including against mites and lice suggests possible wider uses and this is discussed in the penultimate chapter. Current practices in the chemotherapeutic control of sea lice infestations in aquaculture : a review. Molecular phylogenies and host-parasite cospeciation : gophers and lice as a model system. Until recently virtually nothing was known about the relationship between the parasite and the host, or how the host may influence lice at local or population level. Since the early seventies, it has been recognized that the host fish can affect several aspects of lice biology, but the underlying mechanisms are poorly understood. In the second part of this review, these new studies are presented, together with results from other host-parasite model systems where data for caligid sea lice are missing. We know that all persons infested with lice are addicted to scratching themselves, whereby they excoriate their skin and frequently crush the lice upon their bodies. The physiological effects of salmon lice infection on sea trout post smolts. Differences were found between lice on farmed and wild salmon, between lice on farmed salmon in different bays and even putative individual ' farm markers ' within lice populations infesting sea trout. They used these boards as a means of capturing the eggs which could be removed from the lice population thus effecting a form of biological control.
