spatial and temporal changes in lutzomyia longipalpis abundance, a leishmania infantum vector in an urban area in northeastern argentina.this study aimed to analyse changes in the spatial distribution of lutzomyia longipalpis in posadas, an urban area located in northeastern argentina. data were obtained during the summer of 2007 and 2009 through two entomological surveys of peridomiciles distributed around the city. the abundance distribution pattern for 2009 was computed and compared with the previous pattern obtained in 2007, when the first human visceral leishmaniasis cases were reported in the city. vector abundance was also ...024271040
detection of leishmania dna in wild foxes and associated ticks in patagonia, argentina, 2000 km south of its known distribution area.zoonotic visceral leishmaniasis (zvl) is a vector-borne disease affecting humans and other mammals and caused by the protozoan parasite leishmania (leishmania) infantum (syn. l. chagasi), belonging to the l. donovani complex. the regions in northern argentina (above 32 °s) are its southern distribution limit in south america.201627125871

a novel molecular test to diagnose canine visceral leishmaniasis at the point of care.dogs are the principal reservoir hosts of zoonotic visceral leishmaniasis (vl) but current serological methods are not sensitive enough to detect all subclinically infected animals, which is crucial to vl control programs. polymerase chain reaction (pcr) methods have greater sensitivity but require expensive equipment and trained personnel, impairing its implementation in endemic areas. we developed a diagnostic test that uses isothermal recombinase polymerase amplification (rpa) to detect leish ...201526240156
multilocus sequence typing approach for a broader range of species of leishmania genus: describing parasite diversity in argentina.leishmaniasis is a vector-borne protozoan infection affecting over 350 million people around the world. in argentina cutaneous leishmaniasis is endemic in nine provinces and visceral leishmaniasis is spreading from autochthonous transmission foci in seven provinces. however, there is limited information about the diversity of the parasite in this country. implementation of molecular strategies for parasite typing, particularly multilocus sequence typing (mlst), represents an improved approach fo ...201525558029
genetic and clinical characterization of canine leishmaniasis caused by leishmania (leishmania) infantum in northeastern argentina.leishmaniases comprise zoonotic diseases caused by protozoan flagellates of the leishmania genus. they are endemic to south america, and the visceral form has been recently reported in argentina. dogs can play different roles in the leishmania transmission cycles, depending mainly on the species of parasite involved. here we focused on the clinical characterization of canine leishmaniasis (canl) in northeast argentina and on the molecular typing of its etiological agent. the nested polymerase ch ...201526277067
