| [distribution of lutzomyia longipalpis in the argentine mesopotamia, 2010]. | the first case of visceral leishmaniasis (vl) in argentina was reported in 2006 in posadas, misiones. during the summer 2008-2009 lutzomyia longipalpis, the vl vector, and canine vl cases were already spread along the province of corrientes. in order to know the distribution of vl risk, systematic captures of the vector were performed between february and march 2010, in 18 areas of the provinces of entre ríos and corrientes, and the city of puerto iguazú, misiones, with a total of 313 traps/nigh ... | 2011 | 21296716 |
| [distribution of vectors of visceral leishmaniasis in the province of corrientes, 2008]. | visceral leishmaniasis (vl) is a relevant parasitic disease in public health, produced by leishmania infantum chagasi. since the urbanization and emergence in southern brazil and paraguay, the vector lutzomyia longipalpis in formosa, 2004, and the first human visceral leishmaniasis case in misiones, 2006, have been reported in argentina. due to the reports of canine vl, a search of the vector in the province of corrientes, contiguous to misiones, was performed during december 2008. standarized t ... | 2009 | 20053601 |
| urban contamination with zoonotic parasites in the central region of argentina. | adult worms develop in dogs and their eggs are shed in the feces. non-embryonated eggs of toxocara canis become infectious after about 2-6 weeks in the soil and the likelihood of their transmission to humans is through ingestion. in 2004 studies were carried out in the areas of urban recreation in the central region of argentina. a total of 393 dog excrement samples were collected in eight different cities: 59.3 per cent were positive for parasites. these areas of urban recreation are contaminat ... | 2008 | 18977705 |
| species assignation of leishmania from human and canine american tegumentary leishmaniasis cases by multilocus enzyme electrophoresis in north argentina. | sixteen leishmania stocks, 15 isolated from patients with cutaneous (cl), mucocutaneous (mcl), or recurrent cutaneous leishmaniasis, plus one from a dog with cl in salta and corrientes provinces, argentina, were studied by multilocus enzyme electrophoresis. thirteen of the stocks from humans were grouped in two zymodemes; nine termed as kms 1, four as kms 2, and assigned to leishmania (viannia) braziliensis. two additional stocks from cl cases expressed a kms 4 enzyme profile, corresponding to l ... | 2005 | 15891136 |
| 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 |
| chagas disease in north-west argentina: association between trypanosoma cruzi parasitaemia in dogs and cats and infection rates in domestic triatoma infestans. | the association between trypanosoma cruzi parasitaemia in dogs and cats and tryp. cruzi infection rates in domestic triatoma infestans was studied in a cross-sectional survey of 31 houses (89%) in the rural villages of trinidad and mercedes, north-west argentina, where no spraying of insecticides had ever been done. similar prevalence rates of parasitaemia, determined by xenodiagnosis, were recorded among 68 dogs (41.2%) and 28 cats (39.3%). bug infection rates were significantly associated with ... | 1993 | 8465382 |
