| arthropod and filarioid parasites associated with wild rodents in the northeast marshes of buenos aires, argentina. | during 1995, 16 species of arthropods and 2 species of filarioids, totaling 1 287 specimens were collected from 64 wild rodents captured in the hudson natural reserve, buenos aires, argentina. infestation parameters and indexes were analyzed. host specific richness was s = 6, diversity h = 1.48, and relative density rdi = 40%. high values of parasite species richness and diversity were found on oligoryzomys delticola (s = 9; h = 1.40), oxymycterus rufus (s = 9; h = 1.37), and oligoryzomys flaves ... | 2003 | 12973536 |
| spatial and temporal analysis of the distribution of hantavirus pulmonary syndrome in buenos aires province, and its relation to rodent distribution, agricultural and demographic variables. | we studied the spatial and temporal distribution of hantavirus pulmonary syndrome (hps) cases from 1998 to 2001 in the buenos aires province, argentina. hps is a severe viral disease whose natural reservoir are rodents of the subfamily sigmodontinae (muridae) and which occurs in many countries of south and north america. we considered two spatial arrangements: cells of 18.5 x 18.5 km(2); and departments, the political subdivisions of the province, as spatial units. we tested the departure from a ... | 2004 | 15078270 |
| a new species of liniscus (nematoda: trichuridae) from oxymycterus rufus and akodon azarae (cricetidae: sigmodontinae) in buenos aires province, argentina. | liniscus diazae n. sp. (nematoda: trichuridae) is described from the urinary bladder of oxymycterus rufus and akodon azarae (cricetidae: sigmodontinae) from buenos aires province, argentina. liniscus diazae can be differentiated from its congeners by having a much longer spicule and without an elevated vulva. in addition, l. diazae can be distinguished from l. incrassatus and l. himizu by having a longer body length. males are similar in posterior width to l. papillosus and l. himizu, but thinne ... | 2008 | 18576745 |
| determinants of ectoparasite assemblage structure on rodent hosts from south american marshlands: the effect of host species, locality and season. | the relative effects of host species identity, locality and season on ectoparasite assemblages (relative abundances and species richness) harboured by four cricetid rodent hosts (akodon azarae, oligoryzomys flavescens, oxymycterus rufus and scapteromys aquaticus) were assessed across six closely located sites in buenos aires province, argentina. relative abundances of ectoparasites (14 species including gamasid mites, an ixodid tick, a trombiculid mite, lice and fleas), as well as total ectopara ... | 2010 | 20546127 |
| two new species of litomosoides (nematoda: filarioidea) in sigmodontines (rodentia: muridae) from rio de la plata marshland, argentina. | two new species of coelomic filarioid belonging to litomosoides are described from sigmodontine murids from the rio de la plata marshland, argentina. litomosoides bonaerensis n. sp., a parasite of oligoryzomys delticola, belongs to the carinii group and is close to l. silvai, which differs by the head and tail papillae, buccal capsule and cavity, area rugosa, and morphology of the microfilaria. litomosoides oxymycteri n. sp., from oxymycterus rufus, belongs to the sigmodontis group. differential ... | 2000 | 11191910 |
