Quantitative Image Analysis Of Simian Immunodeficiency Virus Replication In Macrophages Coinfected With Mycobacterium Avium Complex, Qingsheng Li, Keith G. Mansfield, Andrew Lackner, Ashley T. Haase

Qingsheng Li Publications

Mycobacterium avium is the most frequent cause of disseminated bacterial infection in patients with human immunodeficiency virus type 1 infection and in rhesus macaques with simian immunodeficiency virus (SIV) infection. This animal model of AIDS was used to test the hypothesis that this frequent association is the result of reciprocal enhancement of replication of both microorganisms. The replication of M. avium and SIV was analyzed in lymphatic tissues obtained from rhesus macaques experimentally inoculated with SIVmac who developed or remained free of overt M. avium infection. In situ hybridization, quantitative image analysis, and staining of M. avium and of macrophages …

Biosystematics And Evolution Of The Triatominae = Biossistemática E Evolução De Triatomíneos, Christopher J. Schofield

Harold W. Manter Laboratory: Library Materials

Abstract

In this paper we summarize the systematics of the 130 currently recognized species of Triatominae and the key features of their evolutionary background. There is increasing evidence that the subfamily has polyphyletic origins, with the various tribes and species groups probably arising from different reduviid lineages in relatively recent times.

Resumo

Neste trabalho resume-se a sistemática das 130 espécies de triatomíneos atualmente reconhecidas, com os elementos principais de sua evolução. Existem evidências crescentes para a origem polifilética da subfamília. As diferentes tribos e grupos de espécies que a compõem teriam surgido recentemente, a partir de diferentes linhagens de reduviídeos.
