Improved HF183 Quantitative Real-Time PCR Assay for Characterization of Human Fecal Pollution in Ambient Surface Water Samples

Creator:: Green, Hyatt C., Haugland, Richard A., Varma, Manju, Millen, Hana T., Borchardt, Mark A., Field, Katharine G., Walters, William A., Knight, R., Sivaganesan, Mano, Kelty, Catherine A., and Shanks, Orin C.
Abstract:: Quantitative real-time PCR (qPCR) assays that target the human-associated HF183 bacterial cluster within members of the genus Bacteroides are among the most widely used methods for the characterization of human fecal pollution in ambient surface waters. In this study, we show that a current TaqMan HF183 qPCR assay (HF183/BFDrev) routinely...

Mycobacterium tuberculosis Alters the Metalloprotease Activity of the COP9 Signalosome

Creator:: Danelishvili, Lia, Babrak, Lmar, Rose, Sasha J., Everman, Jamie, and Bermudez, Luiz E.
Abstract:: Inhibition of apoptotic death of macrophages by Mycobacterium tuberculosis represents an important mechanism of virulence that results in pathogen survival both in vitro and in vivo. To identify M. tuberculosis virulence determinants involved in the modulation of apoptosis, we previously screened a transposon bank of mutants in human macrophages, and...

Distribution of membrane lipids of planktonic Crenarchaeota in the Arabian Sea

Creator:: Sinninghe Damsté, Jaap S., Rijpstra, W. Irene C., Hopmans, Ellen C., Prahl, Fredrick, Wakeham, Stuart G., and Schouten, Stefan
Abstract:: Intact core tetraether membrane lipids of marine planktonic Crenarchaeota were quantified in water column-suspended particulate matter obtained from four depth intervals (~70, 500, 1,000 and 1,500 m) at seven stations in the northwestern Arabian Sea to investigate the distribution of the organisms at various depths. Maximum concentrations generally occurred at...

Kinetic characterization of the soluble butane monooxygenase from Thauera butanivorans, formerly ‘Pseudomonas butanovora’

Creator:: Cooley, Richard B., Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: Soluble butane monooxygenase (sBMO), a three-component di-iron monooxygenase complex expressed by the C2–C9 alkane-utilizing bacterium Thauera butanivorans, was kinetically characterized by measuring substrate specificities for C1–C5 alkanes and product inhibition profiles. sBMO has high sequence homology with soluble methane monooxygenase (sMMO) and shares a similar substrate range, including gaseous and...

Inhibitory Effects of C₂ to C₁₀ 1-Alkynes on Ammonia Oxidation in Two Nitrososphaera Species

Creator:: Taylor, A. E., Taylor, K., Tennigkeit, B., Palatinszky, M., Stieglmeier, M., Myrold, D. D., Schleper, C., Wagner, M., and Bottomley, P. J.
Abstract:: A previous study showed that ammonia oxidation by the Thaumarchaeota Nitrosopumilus maritimus (group 1.1a) was resistant to concentrations of the C₈ 1-alkyne, octyne, which completely inhibits activity by ammonia-oxidizing bacteria. In this study, the inhibitory effects of octyne and other C₂ to C₁₀ 1-alkynes were evaluated on the nitrite production...

Adherence of Clostridium difficile spores to Caco-2 cells in culture

Creator:: Paredes-Sabja, Daniel and Sarker, Mahfuzur R.
Abstract:: Clostridium difficile is the causative agent of the majority of antibiotic associated diarrheas. C. difficile spores are recognized as the morphotype of transmission, infection and persistence. However, there is a lack of knowledge on how C. difficile spores interact with the host’s epithelial surfaces. In this context, we have characterized...

Host-Specific Involvement of the HC Protein in the Long-Distance Movement of Potyviruses

Creator:: Sáenz, Pilar, Salvador, Beatriz, Simón-Mateo, Carmen, Kasschau, Kristin D., Carrington, James C., and García, Juan Antonio
Abstract:: Plum pox virus (PPV) is a member of the Potyvirus genus that, in nature, infects trees of the Prunus genus. Although PPV infects systemically several species of the Nicotiana genus, such as N. clevelandii and N. benthamiana, and replicates in the inoculated leaves of N. tabacum, it is unable to...

Attached and unattached microbial communities in a simulated basalt aquifier under fracture- and porous-flow conditions

Creator:: Lehman, R. Michael, Colwell, Frederick S., and Bala, Greg A.
Abstract:: Bench scale column studies were used to examine the partitioning of microorganisms between groundwater and a geologic medium and to examine the effect of hydrogeology (i.e., porous- versus fracture-flow) on organism partitioning. Replicated columns were constructed with intact basalt core segments that contained natural fractures and with the same basalt...

Diversity of oxygenase genes from Methane- and Ammonia-oxidizing bacteria in the Eastern Snake River Plain aquifier

Creator:: Erwin, Daniel P., Erickson, Issac K., Delwiche, Mark E., Colwell, Fredrick, Strap, Janice L., and Crawford, Ronald L.
Abstract:: PCR amplification, restriction fragment length polymorphism, and phylogenetic analysis of oxygenase genes were used for the characterization of in situ methane- and ammonia-oxidizing bacteria from free-living and attached communities in the Eastern Snake River Plain aquifer. The following three methane monooxygenase (MMO) PCR primer sets were used: A189-A682, which amplifies...
