Morphometric Analysis Of Enteric Lesions In C3h/Hen Mice Inoculated With Serpulina Hyodysenteriae Serotypes 2 And 4 With Or Without Oral Streptomycin Pretreatment, Jagannatha V. Mysore, Gerald Duhamel Jan 1994

Morphometric Analysis Of Enteric Lesions In C3h/Hen Mice Inoculated With Serpulina Hyodysenteriae Serotypes 2 And 4 With Or Without Oral Streptomycin Pretreatment, Jagannatha V. Mysore, Gerald Duhamel

School of Veterinary and Biomedical Sciences: Faculty Publications

The segmental distribution and sequential progression and the role of the indigenous bacterial flora in the development of enteric lesions associated with Serpulina hyodysenteriae infection in laboratory mice have not been defined. We examined the distribution and sequential morphometric changes in the large intestine of mice orally inoculated with S. hyodysenteriae serotypes 2 and 4. To determine the role of colonization resistance conferred by the indigenous bacterial flora, 40 female C3H/HeN mice were administered water alone or water containing 5 mg/mL streptomycin sulfate ad libitum for seven days prior to orogastric inoculation either with S. hyodysenteriae or sterile trypticase soy …


Cooperative Binding Of Ets-1 And Core Binding Factor To Dna., David Wotton, Jacques Ghysdael, Shuwen Wang, Nancy A. Speck, Michael J. Owen Jan 1994

Cooperative Binding Of Ets-1 And Core Binding Factor To Dna., David Wotton, Jacques Ghysdael, Shuwen Wang, Nancy A. Speck, Michael J. Owen

Dartmouth Scholarship

Two phorbol ester-inducible elements (beta E2 and beta E3) within the human T-cell receptor beta gene enhancer each contain consensus binding sites for the Ets and core binding factor (CBF) transcription factor families. Recombinant Ets-1 and purified CBF bound individually to beta E2 and beta E3, in which the Ets and core sites are directly adjacent. In this report, we show that CBF and Ets-1 bind together to beta E2 and beta E3 and that Ets-1-CBF-DNA complexes are favored over the binding of either protein alone to beta E2. Formation of Ets-1-CBF-DNA complexes increased the affinity of Ets-1-DNA interactions and …

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 …
