    • Novel high-rank phylogenetic lineages within a sulfur spring (Zodletone Spring, Oklahoma), revealed using a combined pyrosequencing-Sanger approach 

      Youssef, Noha; Steidley, Brandi L.; Elshahed, Mostafa S. (American Society for Microbiology, 2012-04-15)
      The utilization of high-throughput sequencing technologies in 16S rRNA gene-based diversity surveys has indicated that within most ecosystems, a significant fraction of the community could not be assigned to known microbial ...

    • Novelty and uniqueness patterns of rare members of the soil biosphere 

      Elshahed, Mostafa S.; Youssef, Noha H.; Spain, Anne M.; Sheik, Cody; Najar, Fares Z.; Sukharnikov, Leonid O.; Roe, Bruce A.; Davis, James P.; Schloss, Patrick D.; Bailey, Vanessa L.; Krumholz, Lee R. (American Society for Microbiology, 2008-09)
      Soil bacterial communities typically exhibit a distribution pattern in which most bacterial species are present in low abundance. Due to the relatively small size of most culture-independent sequencing surveys, a detailed ...

    • Nutrients mediate intestinal bacteria-mucosal immune crosstalk 

      Ma, Ning; Guo, Pingting; Zhang, Jie; He, Ting; Kim, Sung Woo; Zhang, Guolong; Ma, Xi (Frontiers Media, 2018-01-24)
      The intestine is the shared site of nutrient digestion, microbiota colonization and immune cell location and this geographic proximity contributes to a large extent to their interaction. The onset and development of a great ...

    • Prevalence of Escherichia coli O157 in cattle feeds in Midwestern feedlots 

      Dodd, Charles C.; Sanderson, Michael W.; Sargeant, Jan M.; Nagaraja, T. G.; Oberst, Richard D.; Smith, Robert A.; Griffin, D. Dee (American Society for Microbiology, 2003-09)
      Comparisons of enrichment methods (with or without antibiotics and with or without a preenrichment step) using gram-negative (GN) broth or tryptic soy broth (TSB) were conducted with feeds inoculated with Escherichia coli ...

    • Resistance of Spiroplasma citri lines to the virus SVTS2 is associated with integration of viral DNA sequences into host chromosomal and extrachromosomal DNA 

      Sha, Yehsiung; Melcher, Ulrich; Davis, Robert E.; Fletcher, Jacqueline (American Society for Microbiology, 1995-11)
      Spiroplasmavirus SVTS2, isolated from Spiroplasma melliferum TS2, produces plaques when inoculated onto lawns of Spiroplasma citri M200H, a derivative of the type strain Maroc R8A2. S. citri strains MR2 and MR3, originally ...

    • Rickettsia parkeri and Candidatus Rickettsia andeanae in Amblyomma maculatum group ticks 

      Noden, Bruce H.; Roselli, Megan A.; Loss, Scott R. (Centers for Disease Control and Prevention (CDC), 2020-02)
      We determined prevalence of Rickettsia spp. in 172 ticks of the Amblyomma maculatum group collected from 16 urban sites in Oklahoma City, Oklahoma, USA, during 2017 and 2018. Most ticks (59.3%) were collected from 1 site; ...

    • Rumen microbial population dynamics during adaptation to a high-grain diet 

      Fernando, S. C.; Purvis, H. T., II; Najar, F. Z.; Sukharnikov, L. O.; Krehbiel, C. R.; Nagaraja, T. G.; Roe, B. A.; DeSilva, U. (American Society for Microbiology, 2010-11)
      High-grain adaptation programs are widely used with feedlot cattle to balance enhanced growth performance against the risk of acidosis. This adaptation to a high-grain diet from a high-forage diet is known to change the ...

    • Subolesin expression in response to pathogen infection in ticks 

      Zivkovic, Zorica; Torina, Alessandra; Mitra, Ruchira; Alongi, Angela; Scimeca, Salvatore; Kocan, Katherine M.; Almazan, Consuelo; Blouin, Edmour F.; Villar, Margarita; Nijhof, Ard M.; Mani, Rinosh; La Barbera, Giuseppa; Caracappa, Santo; Jongejan, Frans; de la Fuente, Jose (BioMed Central, 2010-02-19)
      Background: Ticks (Acari: Ixodidae) are vectors of pathogens worldwide that cause diseases in humans and animals. Ticks and pathogens have co-evolved molecular mechanisms that contribute to their mutual development and ...

    • Tick acquisition of Ehrlichia canis from dogs treated with doxycycline hyclate 

      Schaefer, John J.; Needham, Glen R.; Bremer, William G.; Rikihisa, Yasuko; Ewing, S. A.; Stich, R. W. (American Society for Microbiology, 2007-09)
      Doxycycline generally alleviates clinical monocytic ehrlichiosis, but its efficacy in the control of monocytotropic ehrlichial pathogens requires further investigation. In this study, Ehrlichia canis was detected in dogs ...

    • Trichloroethylene degradation by two independent aromatic-degrading pathways in Alcaligenes eutrophus JMP134 

      Harker, Alan R.; Kim, Young (American Society for Microbiology, 1990-04)
      The bacterium Alcaligenes eutrophus JMP134(pJP4) degrades trichloroethylene (TCE) by a chromosomal phenol-dependent pathway and by the plasmid-encoded 2,4-dichlorophenoxyacetic acid pathway. The two pathways were independent ...

    • Whole-cell kinetics of trichloroethylene degradation by phenol hydroxylase in a Ralstonia eutropha JMP134 derivative 

      Ayoubi, Patricia J.; Harker, Alan R. (American Society for Microbiology, 1998-11)
      The rate, progress, and limits of trichloroethylene (TCE) degradation by Ralstonia eutropha AEK301/pYK3021 whole cells were examined in the absence of aromatic induction. At TCE concentrations up to 800 uM, degradation ...
