| bot fly parasitism (rogenhofera bonaerensis) (diptera, cuterebridae) in the pampean grassland mouse (akodon azarae), in argentina. | seasonality and impact of parasitism by the larvae of rogenhofera bonaerensis (diptera: cuterebridae) in pampean grassland mouse (akodon azarae, rodentia, cricetidae) populations were studied in grasslands and cropfield borders near diego gaynor (buenos aires province, argentina), from november 1985 to december 1986. trapped mice infections ranged from one larva (77%) to four (4%) per host; larvae occurred on tails (75.7%), backs (17.1%), thighs (5.7%), and abdomen (1.4%). prevalence of larvae o ... | 1990 | 2406466 |
| [new findings on junin virus infection in rodents inside and outside the endemic area of hemorrhagic fever in argentina]. | in conjunction with field trials for a vaccine against argentine hemorrhagic fever (ahf), small mammals were trapped during a 28-month period (1 november 1987 to 13 march 1990) in 3 epidemiologically defined areas of the central argentine pampas: northern and central buenos aires provinces were included in the ahf "historic" area, where the disease was common 15-20 years ago, but case rates are currently low; southern santa fe province is the current high-incidence area for ahf; the nonendemic a ... | 1991 | 7476104 |
| correlation between antibody levels in toxoplasma gondii infected pigs and pathogenicity of the isolated parasite. | sera and diaphragm muscle tissues were obtained from 109 commercial pigs between september 1991 and may 1992 from the slaughterhouse at la plata, provincia buenos aires, argentina. anti-toxoplasma gondii igg antibody reactivity to t. gondii antigens were assayed using sera by indirect immunofluorescence assay and immunoblotting technique. anti-t. gondii igg titers at serum dilutions of 1:1024 and higher were noted in 11.0% of the tested sera, and at dilutions of 1:16 and lower in 36.7% of the se ... | 1994 | 8171822 |
| two new species of nippostrongylinae (nematoda: trichostrongylina: heligmonellidae) from the grey leaf-eared mouse graomys griseoflavus (sigmodontinae) in argentina. | two new species of nippostrongylinae, hassalstrongylus puntanus n. sp., and stilestrongylus franciscanus n. sp. are described from the intestine of the grey leaf-eared mouse graomys griseoflavus (waterhouse, 1837) (sigmodontinae) from the province of san luis, argentina. hassalstrongylus puntanus n. sp. is distinguished from the most closely related species h. dollfusi (díaz-ungría, 1963), a parasite of mus musculus from venezuela by longer rays 2, shorter rays 4, proximal half of the dorsal ray ... | 2003 | 12669346 |
| characterization and biological effect of buenos aires urban air particles on mice lungs. | exposure to increased levels of ambient air particulate matter (pm) is associated with increased cardiopulmonary morbidity and mortality. its association with adverse health effects and the still unclear mechanisms of action are of concern worldwide. our objective was to analyze air pm from downtown buenos aires (uap-ba), and evaluate its biological impact on normal airways. we studied the inflammatory response to intranasal instillation of uap-ba in a short-term-exposure mouse model. we analyze ... | 2007 | 17628521 |
| general biochemical and immunological characterization of the venom from the scorpion tityus trivittatus of argentina. | tityus trivittatus is the argentinean scorpion reported to cause the majority of human fatalities in the country, however no systematic studies have been conducted with the venom of this species. this communication describes a general biochemical and immunological characterization of the venom obtained from t. trivittatus scorpions collected in the city of buenos aires and various provinces of argentina: catamarca, cordoba, entre rios, la rioja, santa fe and santiago del estero. these are places ... | 2010 | 19706301 |
| bromadiolone susceptibility in wild and laboratory mus musculus l.(house mice) in buenos aires, argentina. | rodents are major pests in many agricultural systems, where they can cause significant economic losses and involve a sanitary risk. the application of anticoagulant rodenticides for rodent control has showed a decrease in effectiveness through time because of the development of resistant populations and the development of aversion behaviour. the goal of the present study was to test the susceptibility to bromadiolone and the existence of anticoagulant resistance in mus musculus l. (house mouse) ... | 2010 | 19823991 |
| thioridazine cures extensively drug-resistant tuberculosis (xdr-tb) and the need for global trials is now! | thioridazine (tdz) has been shown to have in vitro activity against multidrug-resistant (mdr) and extensively drug-resistant (xdr) strains of mycobacterium tuberculosis, to promote the killing of intracellular mdr and xdr strains and to cure the mouse of antibiotic-susceptible and -resistant pulmonary tuberculosis (tb) infections. recently, tdz was used to cure 10 of 12 xdr-tb patients in buenos aires, argentina. at the time of writing, it is being used for the therapy of non-antibiotic-responsi ... | 2010 | 20188526 |
