| factors limiting the domestic density of triatoma infestans in north-west argentina: a longitudinal study. | reported are the environmental and demographic risk factors associated with the domestic infestation and density of triatoma infestans in three heavily infested rural villages in santiago del estero province, argentina. in a one-factor unadjusted analysis, the number of t. infestans captured per person-hour was associated significantly and negatively with the use of domestic insecticides by householders, type of thatch used in the roofs and the age of the house; and positively with the following ... | 1998 | 9803588 |
| evaluation of dogs as sentinels of the transmission of trypanosoma cruzi in a rural area of north-western argentina. | dogs, the main domestic reservoirs of trypanosoma cruzi in the argentine chaco, may be useful as sentinels of vector-mediated transmission of trypanosoma cruzi in control programmes if canine infections acquired by all other routes could be excluded. in the present study, in the province of santiago del estero, argentina, the dog populations in the neighbouring villages of amamá, trinidad, mercedes, villa matilde and pampa pozo were studied immediately before spraying of residual insecticides (i ... | 1998 | 9924546 |
| immunodiagnosis of trypanosoma cruzi (chagas' disease) infection in naturally infected dogs. | this study reports on the standardization of an enzyme-linked immunosorbent assay (elisa) for detecting specific antibodies anti-trypanosoma cruzi in naturally infected dogs. sera from 182 mongrel dogs of all ages residing in four rural villages in santiago del estero, argentina, were collected in november 1994 and preserved in buffered neutral glycerin. all sera were tested by indirect hemagglutination test (ihat), indirect immunofluorescence test (ifat), and elisa using the flagellar fraction ... | 1998 | 9711341 |
| leptospiral antibodies in stray dogs of moreno, province of buenos aires, argentina. | a serologic survey for leptospirosis in stray dogs from moreno, province of buenos aires, was carried out. sera from 143 randomly collected animals were examined by the microscopic agglutination test. a total of 73 (51.0%) of the dogs have had contact with leptospirae. the predominant leptospiral agglutinnins were to serovar canicola (37.0%) and to a lesser degree against the serovar antigens pyrogenes (4.8%) and autumnalis (2.0%). although a high percentage of seropositive reactions occurred ag ... | 1980 | 7348314 |
| serological and bacteriological detection of brucella canis infection of stray dogs in moreno, argentina. | a focus of b. canis infection was identified in moreno, argentina, among the stray dog population by serologic methods and confirmed in a second survey which included cultural isolations. a counterimmunoelectrophoresis technique using a specific rough brucella surface antigen was applied to the serodiagnosis of canine brucellosis. this method was found to be as effective as the mercaptoethanol tube agglutination test and the gel diffusion test in detecting b. canis antibodies in natural and expe ... | 1980 | 6775870 |
| lutzomyia migonei as putative vector of visceral leishmaniasis in la banda, argentina. | four autochthonous cases of human visceral leishmaniasis (vl) were reported in la banda, santiago del estero from june 2007 to may 2008. in the vicinity of these cases there were 3/47 rk39 sero-positive dogs, and another 4 dogs with vl were reported by passive surveillance. the sero-positive dogs and infected humans lived within a 3.1 km radius. phebotomine sand fly captures were performed twice during november/december 2007 and april 2008. in 20 of the 59 sampled sites in the areas of the human ... | 2010 | 19716797 |
| determinants of the domiciliary density of triatoma infestans, vector of chagas disease. | in two heavily infested rural villages of santiago del estero, argentina, where no indoor-spraying with residual insecticides had ever been carried out by official control services, we studied the influence of roof and wall structure, domestic use of insecticide, family size and the number of domestic dogs, on the domiciliary density of triatoma infestans (klug). bug density was significantly associated with (1) the interaction between insecticide use and type of roof, (2) the structure of indoo ... | 1992 | 1600232 |
