Abstract
Background
An increasing number of reports are calling our attention to the worldwide spread of leishmaniasis.The urbanization of zoonotic visceral leishmaniasis (VL) has been Book observed in different South American countries, due to changes in demographic and ecological factors.In May 2006, VL was detected for the first time in the city of Posadas (Misiones, Argentina).This event encouraged us to conduct a clinical and parasitological pilot survey on domestic dogs from Posadas to identify their potential role as reservoirs for the disease.
Methods
One hundred and ten dogs from the city of Posadas were included in the study.
They were selected based on convenience and availability.All dogs underwent clinical examination.Symptomatology related to canine leishmaniasis was recorded, and peripheral blood and lymph node aspirates were collected.Anti-
Molecular typing was addressed by DNA sequence analysis of the PCR products obtained by
Results
According to clinical examination, 69.1% (76/110) of the dogs presented symptoms compatible with canine leishmaniasis.Serological analyses were positive for 43.6% (48/110) of the dogs and parasite DNA was detected in 47.
3% (52/110).A total of 63 dogs Armored Vehicle (57.3%) were positive by serology and/or PCR.Molecular typing identified
Conclusions
This work confirms recent findings which revealed the presence of
