| vector potential and population dynamics for amblyomma inornatum. | we studied the natural life cycle of amblyomma inornatum and its vector potential in south texas. this tick is distributed throughout south texas and most of central america. a. inornatum represented 1.91% of the ticks collected by carbon dioxide traps during a study of free-living ticks in the tamaulipan biotic province in south texas. the life cycle of a. inornatum in south texas showed a clear seasonal pattern consistent with one generation per year. nymphs emerged in the spring with a peak i ... | 2015 | 25881916 |
| liolaemus lizards (squamata: liolaemidae) as hosts for the nymph of amblyomma parvitarsum (acari: ixodidae), with notes on rickettsia infection. | adults of amblyomma parvitarsum are common ectoparasites of south american camelids of the genera lama and vicugna, occuring in highlands of argentina, bolivia, chile, peru and also in argentinean patagonia. whereas larval stages of this tick are known to feed on small lizards, host records for the nymphal instar have remained unreported. supported by morphological and molecular analyses, herein we report a. parvitarsum nymphs parasitizing two liolaemus species (reptilia: squamata) in the andean ... | 2016 | 27406395 |
| a novel spotted fever group rickettsia infecting amblyomma parvitarsum (acari: ixodidae) in highlands of argentina and chile. | the tick amblyomma parvitarsum (acari: ixodidae) has established populations in andean and patagonic environments of south america. for the present study, adults of a. parvitarsum were collected in highland areas (elevation >3500 m) of argentina and chile during 2009-2013, and tested by pcr for rickettsial infection in the laboratory, and isolation of rickettsiae in vero cell culture by the shell vial technique. overall, 51 (62.2%) out of 82 a. parvitarsum adult ticks were infected by spotted fe ... | 2016 | 26826974 |
| taxonomic key to nymphs of the genus amblyomma (acari: ixodidae) in argentina, with description and redescription of the nymphal stage of four amblyomma species. | in the present study, we provide morphological descriptions of the nymph of amblyomma parvitarsum, a. tonelliae, and redescriptions of a. argentinae and a. sculptum. a taxonomic key, with relevant morphological characters illustrated by scanning electron micrographs, is provided for nymphs of the 24 species of the genus amblyomma occurring in argentina. species included are a. argentinae, a. aureolatum, a. auricularium, a. boeroi, a. brasiliense, a. calcaratum, a. coelebs, a. dissimile, a. dubit ... | 2014 | 25113984 |
| amblyomma parvitarsum (acari: ixodidae): localities, hosts and host-parasite ecology. | only a few aspects of the biology of amblyomma parvitarsum neumann are known. adults of this hard tick species are parasites of south american camelids in the andean plateau of argentina, bolivia, peru and chile and also in the argentine patagonia, but they have been also rarely found on other artyodactils and two species of birds. the larva has been collected from reptiles in northern chile, whereas the hosts for the nymph remain unknown. on nine localities included within altitude tropical and ... | 2014 | 23979654 |
| ticks (acari: argasidae, ixodidae) from middle and pre-hispanic late holocene associated with human activities in northwestern argentina. | one male of amblyomma parvitarsum and one male and a female of ornithodoros sp. were recovered from archaeological layers of the middle holocene in a rock shelter in the province of catamarca, used by hunter-gatherer groups. another two ticks identified as a female and a nymph of argas cf. neghmei were recovered from a layer of the late holocene in other rock shelter in the province of tucumán used by humans of agro-pastoral complex societies previous to the hispanic invasion. the presence of am ... | 2013 | 23219362 |
| a new collection of amblyomma parvitarsum (acari: ixodidae) in peru, with description of a gynandromorph and report of rickettsia detection. | adult stages of amblyomma parvitarsum neumann parasitize wild and domestic camelids of the genera lama and vicugna in highlands of andean plateau and patagonia. within the peruvian andes, few reports have documented this tick-host association, and although reported in chile and argentina, rickettsia-infected a. parvitarsum remains undocumented for this country. here we report a new collection of a. parvitarsum from peru, the finding of the first gynandromorph for the species and high prevalence ... | 2017 | 29045695 |
