genetic variation and epidemiology of echinococcus granulosus in argentina.polymerase chain reaction-ribosomal its-1 dna (rdna) restriction fragment length polymorphism (pcr-rflp) analysis and sequencing of the mitochondrial cytochrome c oxidase subunit 1 (co1) and nadh dehydrogenase 1 (nd1) genes were used to characterize 33 echinococcus granulosus isolates collected from different regions and hosts in argentina, and to determine which genotypes occurred in humans with cystic hydatid disease. the results of the study demonstrated the presence of at least 4 distinct ge ...199910363285
[report on a leptospirosis outbreak in the city of santa fe, argentina, march-april 1998].in march-april 1998 in a neighborhood in the city of santa fe, argentina, there was an outbreak of an acute disease characterized by fever, headaches, and intense myalgias. this article presents the studies surrounding this outbreak and the attempts to identify the source and the mode of transmission. the epidemiological, serological, and clinical findings indicated that the causative agent was leptospira interrogans. as a screening test, macroscopic agglutination with heat-resistant antigen was ...200010715972
capillariidae eggs found in the urine of a free ranging maned wolf from argentina.the first finding of a capillariid in the urinary tract of a free ranging maned wolf (chrysocyon brachyurus) is described. the individual was an adult male attacked by dogs in the locality of cayastacito (santa fe, argentina, 31 degrees 05' s, 60 degrees 34' w). eggs found in urine measured 64.6-66.9 micrometer (mean 65.4 micrometer) x 26.9-31 micrometer (mean 29 micrometer). further studies are needed to determine whether this finding corresponds to a new capillariid species, related to c. brac ...200212118281
[analysis of children with a presumptive diagnosis of toxocariasis in santa fe, argentina].human toxocariasis is a parasitic disease found worldwide. the most important etiological agent is toxocara canis, a dog parasite. humans are infected by the ingestion of their eggs; the eggs hatch in the small intestine and the larvae migrate through the capillaries, taking up residence in different tissues. clinical manifestations are associated with mechanical and/or reaction damage caused by these parasites larvae. clinical diagnosis is difficult. the method applied in this work is the demon ...200818977703
urban contamination with zoonotic parasites in the central region of 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 ...200818977705
[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 ...200920053601
[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 ...201121296716
lutzomyia longipalpis in uruguay: the first report and the potential of visceral leishmaniasis transmission.phlebotomine captures were performed in february 2010 in salto (salto department) and bella unión-cuarein (artigas department), uruguay. bella unión is located across the paraná river from monte caseros, argentina, where a focus of canine visceral leishmaniasis (vl) was reported in 2009. no vl cases have ever been recorded in uruguay and the last reported capture of phlebotominae was in 1932 (lutzomyia cortelezzii and lutzomyia gaminarai). light traps were placed in peridomestic environments, an ...201121655832
