tungiasis in a free-ranging jaguar (panthera onca) population in brazil.tungiasis is an ectoparasitic disease caused by fleas of the genus tunga. the disease is reported to occur mostly in human populations. in wildlife, however, the occurrence and impact of this disease remains uncertain. we captured and examined 12 free-ranging jaguars for the presence of tunga penetrans in the pantanal region of mato grosso do sul state, brazil. tungiasis prevalence was 100% in the population; lesions were confined to the jaguar's paws. t. penetrans was identified based on the ch ...201121863398
[insects know no border.].one of the major consequences of the joined action of demographic pressure and evolution of human activities lies in enormous increase of transportation, both in frequence and speed; taking advantage of these facilities, some arthropods could increase their geographical distribution and create new health threats. several demonstrative examples are exposed in order to illustrate this anthropic dissemination of the vectors : the introduction of anopheles gambiae s.l. in mauritius island between 18 ...199617292311
additional description of a new species of tunga (siphonaptera) from ecuador.a new species of chigoe flea belonging to the genus tunga jarocki, 1838 (siphonaptera, pulicidae, tunginae), tunga trimamillata, was recently described by pampiglione et al. (2002). a better description and more details of the epidemiology of the flea are now presented. it is a species found in goats, pigs and cattle in santa isabel in andean ecuador. this new species differs from its most similar congener, tunga penetrans (l., 1758), by several features, the most important of which are a) the p ...200312669344
the animal reservoir of tunga penetrans in severely affected communities of north-east brazil.tungiasis is a zoonotic ectoparasitosis caused by the sand flea tunga penetrans l. (siphonaptera: tungidae). this disease is hyperendemic in poor communities of north-east brazil, causing considerable morbidity in affected human populations, but the animal reservoirs have not been investigated previously in brazil. to assess the prevalence and intensity of t. penetrans infection in domestic and peri-domestic animals, as well as in the human population, we surveyed two typical communities of nort ...200415641998
