| new genus and six new species of chiggers (acari: trombiculidae and leeuwenhoekiidae) collected from small mammals in argentina. | argentinacarus. n. gen., is proposed with argentinacarus expansus, n. sp., off irenomys tarsalis and akodon longipilis, as type species. quadraseta akodonica, off akodon longipilis and auliscomys micropus, colicus sinpretarsus, off histiotus montanus, parasecia argentinensis off phyllotis xanthopygus, parasecia neuquenensis, off akodon longipilis, and andalgalomacarus xanthopyga, off phyllois xanthopygus and eligmodontia morgani, are described as new. all specimens were collected in argentina. | 1995 | 7650704 |
| a new species of sucking louse (insecta, anoplura) parasitic on auliscomys (mammalia, rodentia) in argentina. | hoplopleura auliscomydis n. sp. is described based on specimens collected from auliscomys micropus (waterhouse 1837), from collń curá, neuquén province, argentina. descriptions are provided for the holotype male, female, first nymphal instar, external architecture of eggs (by scanning electron microscopy), and sites of oviposition, providing differences from its close relative hoplopleura neotomydis castro, gonzález, and cicchino, 1995. the geographical ranges of these 2 species are restricted t ... | 2001 | 11318554 |
| seasonal variation in prevalence of antibody to hantaviruses in rodents from southern argentina. | we conducted a small mammal trapping study to investigate temporal variation in prevalence of infection in hantavirus reservoir populations in the patagonian andes mountain range, rio negro province, argentina. rodent blood samples collected in natural and periurban habitats and at the home of an hantavirus pulmonary syndrome (hps) case patient were analysed by enzyme-linked immunosorbent assay. organ tissue samples were tested by polymerase chain reaction (pcr) and nucleotide sequence analysis. ... | 2001 | 11679129 |
| host range and geographical distribution of ixodes sigelos (acari: ixodidae). | larvae, nymphs and females of ixodes sigelos keirans, clifford and corwin (ixodidae) were collected in 13 localities of the patagonian region of argentina parasitizing eight species of sigmodontine rodents. we report for the first time adults of i. sigelos for argentina. besides, we extend the southern limit of its geographical distribution, and six species of sigmodontines are added as new host species of i. sigelos (phyllotis xanthopygus, euneomys chinchilloides, calomys musculinus, reithrodon ... | 2010 | 20340041 |
| description of a new species of ectinorus (e. spiculatus) (siphonaptera, rhopalopsyllidae) from argentina and a review of the subgenus ichyonus smit, 1987. | a new species, ectinorus spiculatus, is described from phyllotis xanthopygus (waterhouse) and akodon iniscatus thomas from neuquén province, argentina. habitat characteristics are presented for the type locality. a change in status of four additional subspecies of the ectinorus subgenus ichyonus smit is provided. ectinorus onychius onychius jordan and rothschild, ectinorus onychius deplexus smit and ectinorus onychius angularis smit & rosický were elevated to specific status. ectinorus (ichyonus ... | 2011 | 21998530 |
| distributional ecology of andes hantavirus: a macroecological approach. | hantavirus pulmonary syndrome (hps) is an infection endemic in chile and argentina, caused by andes hantavirus (andv). the rodent oligoryzomys longicaudatus is suggested as the main reservoir, although several other species of sigmodontinae are known hosts of andv. here, we explore potential andv transmission risk to humans in southern south america, based on eco-epidemiological associations among: six rodent host species, seropositive rodents, and human hps cases. | 2018 | 29929522 |
