[Visceral leishmaniasis: a study on phlebotomine sand flies and canine infection in Montes Claros, State of Minas Gerais].
Visceral leishmaniasis in Brazil was initially associated with rural areas. However, due to several environmental modifications such as deforestation, urbanization and intense migratory processes,Expand

C‐Reactive Proteins, Limunectin, Lipopolysaccharide‐Binding Protein, and Coagulin
In 1964, Levin and Bang discovered that gram-negative bacterial endotoxin could rapidly induce gelation of Limulus amebocyte lysate. This observation has led to the development of the most sensitiveExpand

Structural analysis of the venom glands of the armed spider Phoneutria nigriventer (Keyserling, 1891): microanatomy, fine structure and confocal observations.
Spiders belonging to the genus Phoneutria (Perty, 1833), most commonly known as 'armed' spiders, are among the most dangerous species in Brazil due to high toxicity of their venom, associated withExpand

Phlebotominae distribution in Janaúba, an area of transmission for visceral leishmaniasis in Brazil.
In Brazil, visceral leishmaniasis (VL) is caused by Leishmania chagasi parasites that are transmitted to man through the bites of infected females of Lutzomyia longipalpis sand flies. In order toExpand

Evaluation of the vectorial capacity of Rhipicephalus sanguineus (Acari: Ixodidae) in the transmission of canine visceral leishmaniasis
The vectorial capacity of Rhipicephalus sanguineus in the transmission of canine visceral leishmaniasis has been evaluated through a laboratory-controlled experiment. One healthy Leishmania-free dogExpand

Epidemiological aspects of vector, parasite, and domestic reservoir in areas of recent transmission and no reported human cases of visceral leishmaniasis in Brazil.
About 97% of the human cases of the American visceral leishmaniasis (VL) occur in Brazil. In the last few years, the disease expanded to medium- and large-sized cities, in which surveillance andExpand
