American visceral Leishmaniasis: a case report J. Venom. Anim. Toxins incl. Trop. Dis.
Langoni,H.; Lucheis,S. B.; Da Silva,R. C.; Castro,A. P. B.; Paes,A. C..
Visceral leishmaniasis is a zoonotic disease caused by parasites of the Leishmania genus. Dog is the major source of infection to man, especially in urban areas. The authors report a case of visceral leishmaniasis in a pit bull female dog from Bocaina, São Paulo, Brazil. The animal presented clinical signs compatible with leishmaniasis, including skin lesions in the body and partial damage of the external ears. The indirect fluorescent antibody test (IFAT) demonstrated a titer of 1280, and promastigote forms of Leishmania sp were isolated by the culture of bone marrow puncture. Cytological analysis of the lymph node and smear of the bone marrow puncture revealed macrophages containing amastigote forms of Leishmania sp in their inner region. The test of...

Immune response to Mycobacterium bovis-AN5 infection in genetically selected mice (selection IV-A) J. Venom. Anim. Toxins incl. Trop. Dis.
Cavaleiro,J. S.; Trindade,B. C.; Balderramas,H. A.; Haanwinckel,M. C.; Pinto,J. G. G.; Oliveira,S. L.; Paes,A. C..
Mice genetically selected for high (H) and low (L) antibody production (Selection IV-A) were used as murine experimental model. The aim of the present work was to evaluate the macrophagic activity and to characterize the immune response in Mycobacterium bovis-AN5 infected mice (3X10(7) bacteria). The response profile previously observed in such strains was not similar to that obtained during M. bovis infection; however, it corroborated works carried out using Selection I, which is very similar to Selection IV-A regarding infection by M. tuberculosis and Bacillus Calmette-Guérin (BCG). Considering bacterial recovery, L IV-A mice showed higher control of the infectious process in the lungs than in the spleen, whereas H IV-A mice presented more resistance in...
