Assessment of the diversity, abundance, and ecological distribution of members of candidate division SR1 reveals a high level of phylogenetic diversity but limited morphotypic diversity
(American Society for Microbiology, 2009-06)We used a combination of 16S rRNA gene clone library surveys, quantitative PCR (qPCR) analysis, and fluorescent in situ hybridization to investigate the diversity, abundance, and distribution of members of candidate division ... -
Bacterial community structure and diversity in a century-old manure-treated agroecosystem
(American Society for Microbiology, 2004-10)Changes in soil microbial community structure and diversity may reflect environmental impact. We examined 16S rRNA gene fingerprints of bacterial communities in six agroecosystems by PCR amplification and denaturing gradient ... -
Characterization of Anaplasma marginale isolated from North American bison
(American Society for Microbiology, 2003-08)Anaplasma marginale (Rickettsiales: Anaplasmataceae), a tick-borne pathogen of cattle, is endemic in tropical and subtropical regions of the world. Although serologic tests have identified American bison, Bison bison, as ... -
Community terminal restriction fragment length polymorphisms reveal insights into the diversity and dynamics of leaf endophytic bacteria
(BioMed Central, 2013-01-03)Background: Plant endophytic bacteria play an important role benefiting plant growth or being pathogenic to plants or organisms that consume those plants. Multiple species of bacteria have been found co-inhabiting plants, ... -
Constitutive expression of the cloned phenol hydroxylase gene(s) from Alcaligenes eutrophus JMP134 and concomitant trichloroethylene oxidation
(American Society for Microbiology, 1996-09)Given the demonstrated phenol-dependent trichloroethylene (TCE) degradation in Alcaligenes eutrophus JMP134 (A. R. Harker and Y. Kim, Appl. Environ. Microbiol. 56:1179-1181, 1990), this work represents a purposeful effort ... -
Crystal structure of Bacillus anthracis dihydrofolate reductase with the dihydrophthalazine-based trimethoprim derivative RAB1 provides a structural explanation of potency and selectivity
(American Society for Microbiology, 2009-07)Bacillus anthracis possesses an innate resistance to the antibiotic trimethoprim due to poor binding to dihydrofolate reductase (DHFR); currently, there are no commercial antibacterials that target this enzyme in B. ... -
Effects of environmental and nutritional factors on production of the polyketide phytotoxin coronatine by Pseudomonas syringae pv. glycinea
(American Society for Microbiology, 1993-05)Pseudomonas syringae pv. glycinea PG4180 produces the polyketide phytotoxin coronatine. The effects of environmental, nutritional, and host factors on growth and coronatine production by PG4180 were examined by varying the ... -
Environmental determinants of and impact on childhood asthma by the bacterial community in household dust
(American Society for Microbiology, 2010-04)Asthma increased dramatically in the last decades of the 20th century and is representative of chronic diseases that have been linked to altered microbial exposure and immune responses. Here we evaluate the effects of ... -
Genomic comparison of plant pathogenic and nonpathogenic Serratia marcescens strains by suppressive subtractive hybridization
(American Society for Microbiology, 2005-12)Cucurbit yellow vine disease (CYVD) is caused by disease-associated Serratia marcescens strains that have phenotypes significantly different from those of nonphytopathogenic strains. To identify the genetic differences ... -
High-temperature enzymatic breakdown of cellulose
(American Society for Microbiology, 2011-08)Cellulose is an abundant and renewable biopolymer that can be used for biofuel generation; however, structural entrapment with other cell wall components hinders enzyme-substrate interactions, a key bottleneck for ethanol ... -
Identification of the inducing agent of the 2,4-dichlorophenoxyacetic acid pathway encoded by plasmid pJP4
(American Society for Microbiology, 1997-01)The inducing agent of the 2,4-dichlorophenoxyacetic acid (2,4-D) pathway of Alcaligenes eutrophus JMP134 (pJP4) was determined through the analysis of promoterless lacZ transcriptional fusions with tfd structural genes. ... -
In vitro efficacy of antibiotics commonly used to treat human plague against intracellular Yersinia pestis
(American Society for Microbiology, 2011-08)Yersinia pestis initiates infection as a facultative intracellular parasite in host macrophages; however, little is known about the efficacy of antibiotics commonly used to treat human plague against intracellular Y. pestis. ... -
In vitro efficacy of new antifolates against trimethoprim-resistant Bacillus anthracis
(American Society for Microbiology, 2007-12)Bacillus anthracis is innately resistant to trimethoprim (TMP), a synthetic antifolate that selectively inhibits several bacterial dihydrofolate reductases (DHFRs) but not human DHFR. Previously, we were able to confirm ... -
Influence of light on bacterioplankton production and respiration in a subtropical coral reef
(Inter Research, 1998-02-13)The influence of sunlight on bacterioplankton production [14C-leucine (Leu) and 3H-thymidine (TdR) incorporation; changes in cell abundances] and O2 consumption was investigated in a shallow subtropical coral reef located ... -
Influence of the drilling mud formulation process on the bacterial communities in thermogenic natural gas wells of the Barnett Shale
(American Society for Microbiology, 2011-07)The Barnett Shale in north central Texas contains natural gas generated by high temperatures (120 to 150°C) during the Mississippian Period (300 to 350 million years ago). In spite of the thermogenic origin of this gas, ... -
inlA premature stop codons are common among Listeria monocytogenes isolates from foods and yield virulence-attenuated strains that confer protection against fully virulent strains
(American Society for Microbiology, 2008-11)Previous studies showed that a considerable proportion of Listeria monocytogenes isolates obtained from foods carry a premature stop codon (PMSC) mutation in inlA that leads to production of a truncated and secreted InlA. ... -
Microbial community structure in petroleum-contaminated sediments corresponds to geophysical signatures
(American Society for Microbiology, 2007-05)The interdependence between geoelectrical signatures at underground petroleum plumes and the structures of subsurface microbial communities was investigated. For sediments contaminated with light non-aqueous-phase liquids, ... -
