Canine visceral leishmaniasis in São José de Ribamar, Maranhão State, Brazil

“…The first report of L. chagasi in Brazil was made by Penna (1934) during histological examination of liver specimens though post-mortem viscerotomy. Soon after, Chagas et al (1937Chagas et al ( , 1938 observed cases of AVL in domestic dogs. Later, wild reservoirs represented by the foxes Lycalopex vetulus (Deane and Deane, 1954a,b) and Cerdocyon thous (Lainson et al, 1969;Silveira et al, 1982) were also reported.…”

The dispersion of Lutzomyia longipalpis in urban areas

“…After Penna and Chagas's classic works 2,3 , several human cases of VL were diagnosed in different regions of America, with Brazil having the greatest endemic presence of the disease with active transmission distinct from the original Mediterranean cycle. By the 1950s, Brazil had a clear picture of the VL endemic zones, which were mainly restricted to the northeast region and some specifi c areas in the States of Pará and Minas Gerais.…”

Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae): a review

“…The first report of L. chagasi in Brazil was made by Penna (1934) during histological examination of liver specimens through post-mortem viscerotomy. Soon after, Chagas et al (1937Chagas et al ( , 1938 observed cases of AVL in domes-tic dogs and L. longipalpis was suspected to be the primary vector. Later, wild reservoirs represented by the foxes Lycalopex vetulus (Deane and Deane 1954a,b) and Cerdocyon thous (Lainson et al 1969, Silveira et al 1982 were also reported although the role of opossums as peridomestic hosts was also considered (Sherlock et al 1984).…”
