Prehistoric Pathoecology As Represented By Parasites Of A Mummy From The Peruaçu Valley, Brazil, Karl Reinhard, Adauto Araújo
Prehistoric Pathoecology As Represented By Parasites Of A Mummy From The Peruaçu Valley, Brazil, Karl Reinhard, Adauto Araújo
Karl Reinhard Publications
Paleopathologists have begun exploring the pathoecology of parasitic diseases in relation to diet and environment. We are summarizing the parasitological findings from a mummy in the site of Lapa do Boquete, a Brazilian cave in the state of Minas Gerais. These findings in context of the archaeology of the site provided insights into the pathoecology of disease transmission in cave and rockshelter environments. We are presenting a description of the site followed by the evidence of hookworm, intestinal fluke, and Trypanosoma infection with resulting Chagas disease in the mummy discovered in the cave. These findings are used to reconstruct the …

The immunomodulatory properties of lipophosphoglycans (LPG) from New World species of Leishmania have been assessed in Leishmania infantum and Leishmania braziliensis, the causative agents of visceral and cutaneous leishmaniasis, respectively. This glycoconjugate is highly polymorphic among species with variation in sugars that branch off the conserved Gal(β1,4)Man(α1)-PO4 backbone of repeat units. Here, the immunomodulatory activity of LPGs from Leishmania amazonensis, the causative agent of diffuse cutaneous leishmaniasis, was evaluated in two strains from Brazil. One strain (PH8) was originally isolated from the sand fly and the other (Josefa) was isolated from a human case. The ability of …
Taxonomic Review Of The Wingmite Genus Cameronieta (Acari: Spinturnicidae) On Neotropical Bats, With A New Species From Northeastern Brazil, Juliana C. Almeida, Donald D. Gettinger, Scott Lyell Gardner
Taxonomic Review Of The Wingmite Genus Cameronieta (Acari: Spinturnicidae) On Neotropical Bats, With A New Species From Northeastern Brazil, Juliana C. Almeida, Donald D. Gettinger, Scott Lyell Gardner
Scott L. Gardner Publications
The ectoparasitic mite genus Cameronieta (Acari: Mesostigmata: Spinturnicidae) is endemic to the New World and associated exclusively with bats of the family Mormoopidae. The genus consists of 7 species, 4 broadly distributed through the Caribbean and mainland of North and South America, and 3 species limited to the Greater Antilles archipelago. We present a brief review of the taxonomic history, redefine the genus, and consider some questions that remain concerning the biology and systematics of the group. A new species, Cameronieta almaensis n. sp., is described from the wings of Pteronotus parnellii collected from the Serra das Almas Reserve, in …
