Identification of an avian polyomavirus associated with Adélie penguins (Pygoscelis adeliae)

Creator:: Varsani, Arvind, Porzig, Elizabeth L., Jennings, Scott, Kraberger, Simona, Farkas, Kata, Julian, Laurel, Masaro, Melanie, Ballard, Grant, and Ainley, David G.
Abstract:: Little is known about viruses associated with Antarctic animals, although they are probably widespread. We recovered a novel polyomavirus from Adélie penguin (Pygoscelis adeliae) faecal matter sampled in a subcolony at Cape Royds, Ross Island, Antarctica. The 4988 nt Adélie penguin polyomavirus (AdPyV) has a typical polyomavirus genome organization with...

Negative regulation of germination-arrest factor production in Pseudomonas fluorescens WH6 by a putative extracytoplasmic function sigma factor

Creator:: Okrent, Rachel A., Halgren, Anne B., Azevedo, Mark D., Chang, Jeff H., Mills, Dallice I., Armstrong, Donald J., Maselko, Maciej, Bonowetz, Gary M., and Trippe, Kristin M.
Abstract:: Pseudomonas fluorescens WH6 secretes a germination-arrest factor (GAF) that we have identified previously as 4-formylaminooxyvinylglycine. GAF irreversibly inhibits germination of the seeds of numerous grassy weeds and selectively inhibits growth of the bacterial plant pathogen Erwinia amylovora. WH6-3, a mutant that has lost the ability to produce GAF, contains a...

Identification of Mycobacterium avium genes associated with resistance to host antimicrobial peptides

Creator:: Motamedi, Nima, Danelishvili, Lia, and Bermudez, Luiz E.
Abstract:: Antimicrobial peptides are an important component of the innate immune defense. Mycobacterium avium subsp hominissuis (M. avium) is an organism that establishes contact with the respiratory and gastrointestinal mucosa as a necessary step for infection. M. avium is resistant to high concentrations of polymyxin B, a surrogate for antimicrobial peptides....

Genetics of germination-arrest factor (GAF) production by Pseudomonas fluorescens WH6: identification of a gene cluster essential for GAF biosynthesis

Creator:: Halgren, Anne, Maselko, Maciej, Azevedo, Mark, Mills, Dallice, Armstrong, Donald, and Banowetz, Gary
Abstract:: The genetic basis of the biosynthesis of the germination-arrest factor (GAF) produced by Pseudomonas fluorescens WH6, and previously identified as 4-formylaminooxyvinylglycine, has been investigated here. In addition to inhibiting the germination of a wide range of grassy weeds, GAF exhibits a selective antimicrobial activity against the bacterial plant pathogen Erwinia...

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...

NhaP1 is a K+(Na+)/H+ antiporter required for growth and internal pH homeostasis of Vibrio cholerae at low extracellular pH

Creator:: Quinn, Matthew J., Resch, Craig T., Sun, Jonathan, Lind, Erin J., Dibrov, Pavel, and Hase, Claudia C.
Abstract:: Vibrio cholerae has adapted to a wide range of salinity, pH and osmotic conditions, enabling it to survive passage through the host and persist in the environment. Among the many proteins responsible for bacterial survival under these diverse conditions, we have identified Vc-NhaP1 as a K+(Na+)/H+ antiporter essential for V....

Host serum factor triggers germination of Clostridium perfringens spores lacking the cortex hydrolysis machinery

Creator:: Paredes-Sabja, Daniel and Sarker, Mahfuzur R.
Abstract:: Clostridium perfringens type A is the causative agent of a variety of histotoxic and enteric diseases. The ability of C. perfringens spores to germinate in vivo might be due to the presence of nutrient germinants in the host tissue and blood. In the current study, we investigated the ability of...

D-Lactate metabolism and the obligate requirement for CO2 during growth on nitrite by the facultative lithoautotroph Nitrobacter hamburgensis

Creator:: Starkenburg, Shawn R., Arp, Daniel J., and Bottomley, Peter J.
Abstract:: Nitrobacter hamburgensis X14 is a facultative lithoautotroph that conserves energy from the oxidation of nitrite (NO 2 ) and fixes carbon dioxide (CO2) as its sole source of carbon. The availability of the N. hamburgensis X14 genome sequence initiated a re-examination of its mixotrophic and organotrophic potential, as genes encoding...

Thauera butanivorans sp. nov., a C₂–C₉ alkane-oxidizing bacterium previously referred to as ‘Pseudomonas butanovora’

Creator:: Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: The placement of ‘Pseudomonas butanovora’ in the genus Thauera was proposed previously, based on 16S rRNA gene sequence analysis, upon further studies of taxonomical characteristics. In this study, physiological characteristics and DNA–DNA reassociation data are presented and the transfer of ‘P. butanovora’ to the genus Thauera is proposed. The original...

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...
