Cardiac Lesions in 30 Dogs Naturally Infected With Leishmania infantum chagasi [PDF]

Veterinary Pathology, 2013
The hearts of 30 dogs naturally infected with Leishmania infantum chagasi were evaluated histologically and immunohistochemically. Myocardial lesions were detected in all dogs, including lymphoplasmacytic myocarditis (27/30), myonecrosis (24/30), increased interstitial collagen (22/30), lepromatous-type granulomatous myocarditis (7/30), fibrinoid ...

Comparative proteomic analysis of antimony-resistant and -susceptible Leishmania braziliensis and Leishmania infantum chagasi lines

Molecular and Biochemical Parasitology, 2013
The emergence of drug-resistant Leishmania species is a significant problem in several countries. A comparative proteomic analysis of antimony-susceptible and antimony-resistant Leishmania braziliensis (LbSbR) and Leishmania infantum chagasi (LcSbR) lines was carried out using two-dimensional gel electrophoresis (2-DE) followed by mass spectrometry (LC/
