Phthirapteran ectoparasites

Phthirapteran ectoparasites

  • Ivan Pavlovic added an answer:
    Is the prevalence of ectoparasites proportional to the risk of pathogen infection?

    I am looking for experimental evidence (or convincing non-experimental evidence) that the number of fleas or ticks an individual animal harbors is related to that individual's risk of infection by a vector-borne pathogen.  Can anyone point me to some compelling literature?

    At first, must be obradititi attention to the type of parasite and host. This correlation is important in the outbreak pathogen. Quantity - number hematofagih species is certainly much more pathogenic than malofaga which are primarily stresogen pathogens.
    The fitness of the animals, age and housing conditions are also important when identification of parasites. The cage systems in laying hens infection malofagma receive a drastic decline in production as well as infections with poultry red mite. Normally, the pathological effect of mites is far more important. Cat flea (Ctenocephalides felis felis) in chickens and goats to two weeks, causing significant mortality and the like.
    Parasitocenosis ratio is the ratio of the complex ecological, biological and physiological correlations hosts and parasites at which abiotic factors play a major role and therefore often determine the movement of an infection from an extremely benign infection drastic mortality.
    Vector role of arthropods that are hematofage are a special problem because of diet and vector role in the spread of infection other etiology. 

    My experience in these 28 years of ectoparasites tests indicate that they have a lot of great breadth in the choice of the host but also a higher or lower pathogenicity in relation to primary and secondary hosts. For example, the reproduction of ticks, which was observed in dogs and then found in the lizard was not the same (it was much smaller). Cat fleas was less pathogens in squirrels than in dogs and etc.
    Number of ectoparasites is certainly very important, but it must be seen in correlation with the owner - whether it is on the primary or secondary to the cause. The quantity and quality of these infections are often not in the expected correlation.

  • S.K. Singh asked a question:
    Why does the population of lice (phthirapteran) of mammals increase in winter and birds in summer?
    Literature reveals that mammalian phthirapteran ectoparasites increase in winter but the actual reason is still not clear. I need help to find out the best answer.
