Invasive infection with organisms of the Mycobacterium avium complex (MAC) is common among patients with advanced human immunodeficiency virus infection. In previous studies, we analyzed multiple individual colonies of MAC isolated from specimens obtained at the same time and observed that 14 to 20% of patients are simultaneously infected with more than one strain. In this study, we examined sequential isolates from 12 patients with AIDS who had two or more MAC isolates available from clinical specimens collected more than 1 week apart; the intervals between the first and last specimens ranged from 8 to 192 (median, 46) days. For …


Antiparasitic And Antiproliferative Effects Of Indoleamine 2,3-Dioxygenase Enzyme Expression In Human Fibroblasts., Sohan L. Gupta, Joseph M. Carlin, Padma Pyati, Wei Dai, Elmer R. Pfefferkorn, Martin J. Murphy Jr Jan 1994

Antiparasitic And Antiproliferative Effects Of Indoleamine 2,3-Dioxygenase Enzyme Expression In Human Fibroblasts., Sohan L. Gupta, Joseph M. Carlin, Padma Pyati, Wei Dai, Elmer R. Pfefferkorn, Martin J. Murphy Jr

Dartmouth Scholarship

Studies were carried out to evaluate the proposed role of indoleamine 2,3-dioxygenase (INDO) induction in the antimicrobial and antiproliferative effects of gamma interferon (IFN-gamma) in human fibroblasts. The INDO cDNA coding region was cloned in the pMEP4 expression vector, containing the metallothionein (MTII) promoter in the sense (+ve) or the antisense (-ve) orientation. Human fibroblasts (GM637) stably transfected with the sense construct expressed INDO activity after treatment with CdCl2 or ZnSO4, but cells transfected with the antisense construct did not. The growth of Chlamydia psittaci was strongly inhibited in INDO +ve cells but not in INDO -ve cells after treatment …
