Stawonogi - wektory chorob transmisyjnych

100%
Arthropods may be obligatory or facultative vectors of transmissible diseases. Various relations exist between arthropod reservoirs and vectors of which the most important are trophic, topic and phoric associations. Arthropods could be biological or mechanical vectors and transmit pathogens in an active or passive way. Among different taxonomic groups of arthropod vectors the mostimportant are hard ticks (Ixodidae). The following biological features of ticks support their role as reservoirs and vectors of disease agents: anatomical structure; feeding mechanisms, mostly an ability of the intake of large volumes of host blood and an ability of the injection of large amounts of saliva into host's body; change of hosts during life cycle; a possibility of the long persistence of pathogens in tick's population due to the transstadial, transovarial, transspermal and hyperparasitic transmission, and parallel feeding; longevity of ticks compared to rodents; a possibility of geographical distribution.

Fauna kleszczy [Acari: Ixodida] w Polsce

100%
20 valid species of Ixodida (3 Argasidae and 17 Ixodidae) are actually recognized as permanently existing in Poland. Cases of transferring 5 other Ixodidae were also recorded. Argasidae are nests- and burrows-dwelling species having multi-host development cycle, they are mainly synanthropic and semisynanthropic, nocturnal active, with the peak seasonal activity in the middle of summer. The most of Polish Ixodidae species are burrows- and nests-dwelling parasites, more common species are out of nest-dwelling, having three-host development cycle; they are basically polyxenic, active during the warm season of year, normally with two peaks of activity - in spring and at the end of summer, beginning of autumn; in most cases live in forests.
The paper presents current knowledge of ticks occurring in Poland, their medical importance, and a review of recent studies implemented in the Polish research centres on ticks and their significance in the epidemiology of transmissible diseases. In the Polish fauna there are 19 species of ticks (Ixodida) recognized as existing permanently in our country: Argas reflexus, Argas polonicus, Carios vespertilionis, Ixodes trianguliceps, Ixodes arboricola, Ixodes crenulatus, Ixodes hexagonus, Ixodes lividus, Ixodes rugicollis, Ixodes caledonicus, Ixodes frontalis, Ixodes simplex, Ixodes vespertilionis, Ixodes apronophorus, Ixodes persulcatus, Ixodes ricinus, Haemaphysalis punctata, Haemaphysalis concinna, Dermacentor reticulatus. Occasionally, alien species of ticks transferred to the territory of Poland are recorded: Amblyomma sphenodonti, Amblyomma exornatum, Amblyomma flavomaculatum, Amblyomma latum, Amblyomma nuttalli, Amblyomma quadricavum, Amblyomma transversale, Amblyomma varanensis, Amblyomma spp., Dermacentor marginatus, Hyalomma aegyptium, Hyalomma marginatum, Ixodes eldaricus, Ixodes festai, Rhipicephalus rossicus, Rhipicephalus sanguineus. The most common species of the highest medical and veterinary importance in Poland is invariably Ixodes ricinus. The review also sets out information on the risks of tickborne diseases in recreational areas of large cities in Poland, ticks as the cause of occupational diseases and dangerous species of ticks attacking people outside the Polish borders. Selected problems of the biology of ticks, the spread of alien species transferred on hosts and prevention of tick attacks have also been presented. The Polish studies on ticks are a valuable contribution to global research on the Ixodida.
A partly fed female of I. festai was collected from Turdus merula L. cought in Hel Peninsula (Southern Coast of Baltic Sea). This species (known only as females) is a parasite of birds, and inhabits western part of the Mediterrean area. I. festai is a second species after Hyalomma marginatum which probably every spring is transferred by migratory bird into territory of Poland. This finding is the first recorded case of transfer of I. festai to Poland, therefore the description of female is given.
