Data Acceptance Criteria for Standardized Human-Associated Fecal Source Identification Quantitative Real-Time PCR Methods

Creator:: Shanks, Orin C., Kelty, Catherine A., Oshiro, Robin, Haugland, Richard A., Madi, Tania, Brooks, Lauren, Field, Katharine G., and Sivaganesan, Mano
Abstract:: There is growing interest in the application of human-associated fecal source identification quantitative real-time PCR (qPCR) technologies for water quality management. The transition from a research tool to a standardized protocol requires a high degree of confidence in data quality across laboratories. Data quality is typically determined through a series...

Steady-State Growth under Inorganic Carbon Limitation Conditions Increases Energy Consumption for Maintenance and Enhances Nitrous Oxide Production in Nitrosomonas europaea

Creator:: Mellbye, Brett L., Giguere, Andrew, Chaplen, Frank, Bottomley, Peter J., and Sayavedra-Soto, Luis A.
Abstract:: Nitrosomonas europaea is a chemolithoautotrophic bacterium that oxidizes ammonia (NH₃) to obtain energy for growth on carbon dioxide (CO₂) and can also produce nitrous oxide (N₂O), a greenhouse gas. We interrogated the growth, physiological, and transcriptome responses of N. europaea to conditions of replete (>5.2 mM) and limited inorganic carbon...

Identifying Potential Mechanisms Enabling Acidophily in the Ammonia-Oxidizing Archaeon "Candidatus Nitrosotalea devanaterra"

Creator:: Lehtovirta-Morley, Laura E., Sayavedra-Soto, Luis A., Gallois, Nicolas, Schouten, Stefan, Stein, Lisa Y., Prosser, James I., and Nicol, Graeme W.
Abstract:: Ammonia oxidation is the first and rate-limiting step in nitrification and is dominated by two distinct groups of microorganisms in soil: ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB). AOA are often more abundant than AOB and dominate activity in acid soils. The mechanism of ammonia oxidation under acidic conditions has...

Transcriptional Profile during Deoxycholate-Induced Sporulation in a Clostridium perfringens Isolate Causing Foodborne Illness

Creator:: Yasugi, Mayo, Okuzaki, Daisuke, Kuwana, Ritsuko, Takamatsu, Hiromu, Fujita, Masaya, Sarker, Mahfuzur R., and Miyake, Masami
Abstract:: Clostridium perfringens type A is a common source of foodborne illness (FBI) in humans. Vegetative cells sporulate in the small intestinal tract and produce the major pathogenic factor C. perfringens enterotoxin. Although sporulation plays a critical role in the pathogenesis of FBI, the mechanisms inducing sporulation remain unclear. Bile salts...

Mutation of the murC and murB Genes Impairs Heterocyst Differentiation in Anabaena sp. Strain PCC 7120

Creator:: Videau, Patrick, Rivers, Orion S., Ushijima, Blake, Oshiro, Reid T., Kim, Min Joo, Philmus, Benjamin, and Cozy, Loralyn M.
Abstract:: To stabilize cellular integrity in the face of environmental perturbations, most bacteria, including cyanobacteria, synthesize and maintain a strong, flexible, three-dimensional peptidoglycan lattice. Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium capable of differentiating morphologically distinct nitrogen-fixing heterocyst cells in a periodic pattern. While heterocyst development has been shown...

An Interspecies Signaling System Mediated by Fusaric Acid Has Parallel Effects on Antifungal Metabolite Production by Pseudomonas protegens Strain Pf-5 and Antibiosis of Fusarium spp.

Creator:: Quecine, Maria Carolina, Kidarsa, Teresa A., Goebel, Neal C., Shaffer, Brenda T., Henkels, Marcella D., Zabriskie, T. Mark, and Loper, Joyce E.
Abstract:: Pseudomonas protegens strain Pf-5 is a rhizosphere bacterium that suppresses soilborne plant diseases and produces at least seven different secondary metabolites with antifungal properties. We derived mutants of Pf-5 with single and multiple mutations in biosynthesis genes for seven antifungal metabolites: 2,4-diacetylphoroglucinol (DAPG), pyrrolnitrin, pyoluteorin, hydrogen cyanide, rhizoxin, orfamide A,...

Chloroflexi CL500-11 Populations That Predominate Deep-Lake Hypolimnion Bacterioplankton Rely on Nitrogen-Rich Dissolved Organic Matter Metabolism and C₁ Compound Oxidation

Creator:: Denef, Vincent J., Mueller, Ryan S., Chiang, Edna, Liebig, James R., and Vanderploeg, Henry A.
Abstract:: The Chloroflexi CL500-11 clade contributes a large proportion of the bacterial biomass in the oxygenated hypolimnia of deep lakes worldwide, including the world's largest freshwater system, the Laurentian Great Lakes. Traits that allow CL500-11 to thrive and its biogeochemical role in these environments are currently unknown. Here, we found that...

Enhanced Direct Major Histocompatibility Complex Class I Self-Antigen Presentation Induced by Chlamydia Infection

Creator:: Cram, Erik D., Simmons, Ryan S., Palmer, Amy L., Hildebrand, William H., Rockey, Daniel D., and Dolan, Brian P.
Abstract:: The direct major histocompatibility complex (MHC) class I antigen presentation pathway ensures intracellular peptides are displayed at the cellular surface for recognition of infected or transformed cells by CD8⁺ cytotoxic T lymphocytes. Chlamydia spp. are obligate intracellular bacteria and, as such, should be targeted by CD8⁺ T cells. It is...

Simultaneous Host-Pathogen Transcriptome Analysis during Granulibacter bethesdensis Infection of Neutrophils from Healthy Subjects and Patients with Chronic Granulomatous Disease

Creator:: Greenberg, David E., Sturdevant, Daniel E., Marshall-Batty, Kimberly R., Chu, Jessica, Pettinato, Anthony M., Virtaneva, Kimmo, Lane, John, Geller, Bruce L., Porcella, Stephen F., Gallin, John I., Holland, Steven M., and Zarember, Kol A.
Abstract:: Polymorphonuclear leukocytes (PMN) from patients with chronic granulomatous disease (CGD) fail to produce microbicidal concentrations of reactive oxygen species (ROS) due to mutations in NOX2. Patients with CGD suffer from severe, life-threatening infections and inflammatory complications. Granulibacter bethesdensis is an emerging Gram-negative pathogen in CGD that resists killing by PMN...

Examining the Use of Ceftaroline in the Treatment of Streptococcus pneumoniae Meningitis with Reference to Human Cathelicidin LL-37

Creator:: Sakoulas, George, Nonejuie, Poochit, Kullar, Ravina, Pogliano, Joseph, Rybak, Michael J., and Nizet, Victor
Abstract:: Five cases of bacterial meningitis treated with ceftaroline (4 Streptococcus pneumoniae and 1 Staphylococcus aureus) are summarized here. The pharmacodynamics of human cathelicidin LL-37 and ceftaroline were evaluated against S. pneumoniae. Patients who received ceftaroline 600 mg every 8 h (q8h) (1 S. aureus and 3 S. pneumoniae) were successfully...
