The Clermont Escherichia coli phylo‐typing method revisited: improvement of specificity and detection of new phylo‐groups Tập 5 Số 1 - Trang 58-65 - 2013
Olivier Clermont, Julia K. Christenson, Érick Denamur, David M. Gordon
SummaryThere is extensive genetic substructure within the species Escherichia
coli. In 2000 a simple triplex PCR method was described by Clermont and
colleagues that enables an E. coli isolate to be assigned to one of the
phylo‐groups A, B1, B2 or D. The growing body of multi‐locus sequence data and
genome data for E. coli has refined our understanding of E. coli's phylo‐group
structure and eight ... hiện toàn bộ
Climate change: a catalyst for global expansion of harmful cyanobacterial blooms Tập 1 Số 1 - Trang 27-37 - 2009
Hans W. Paerl, Jef Huisman
SummaryCyanobacteria are the Earth's oldest known oxygen‐evolving photosynthetic
microorganisms, and they have had major impacts on shaping our current
atmosphere and biosphere. Their long evolutionary history has enabled
cyanobacteria to develop survival strategies and persist as important primary
producers during numerous geochemical and climatic changes that have taken place
on Earth during the... hiện toàn bộ
Bacterial seed endophytes: genera, vertical transmission and interaction with plants Tập 7 Số 1 - Trang 40-50 - 2015
Sascha Truyens, Nele Weyens, Ann Cuypers, Jaco Vangronsveld
SummaryAlthough the importance of plant‐associated microorganisms for plant
growth and health was getting more recognition recently, the role of
seed‐associated microorganisms, and especially seed endophytic bacteria, still
is underestimated. Nevertheless, these associations could be beneficial for
germination and seedling establishment as seed endophytic bacteria are already
present in these very... hiện toàn bộ
Local and regional factors influencing bacterial community assembly Tập 4 Số 1 - Trang 1-9 - 2012
Eva S. Lindström, Silke Langenheder
SummaryThe classical view states that microbial biogeography is not affected by
dispersal barriers or historical events, but only influenced by the local
contemporary habitat conditions (species sorting). This has been challenged
during recent years by studies suggesting that also regional factors such as
mass effect, dispersal limitation and neutral assembly are important for the
composition of l... hiện toàn bộ
Diversity and pathogenecity of Vibrio species in cultured bivalve molluscs Tập 2 Số 1 - Trang 34-43 - 2010
Roxana Beaz‐Hidalgo, Sabela Balboa, Jesús L. Romalde, María José Figueras
SummaryShellfish production is seriously affected by bacterial pathogens that
cause high losses in hatcheries and in the aquaculture sector. A number of
Vibrio species are considered important pathogens and have provoked severe
mortality outbreaks. The pathologies caused by vibrios in bivalves have been
described since the 1960s; however, over recent years, successive episodes of
high mortality ha... hiện toàn bộ
Restructuring of the amphibian gut microbiota through metamorphosis Tập 5 Số 6 - Trang 899-903 - 2013
Kevin D. Kohl, Tawnya L. Cary, William H. Karasov, M. Denise Dearing
SummaryVertebrates maintain complex symbioses with a diverse community of
microbes residing within their guts. The microbial players in these symbioses
differ between major taxa of vertebrates, such that fish and amniotes maintain
notably different communities. To date, there has not been a culture‐independent
inventory of an amphibian gut microbial community. Here, we compared gut
microbial commu... hiện toàn bộ
Siderophore‐promoted dissolution of smectite by fluorescent Pseudomonas Tập 6 Số 5 - Trang 459-467 - 2014
Claire Ferret, Thibault Sterckeman, Jean-Yves Cornu, Sophie Gangloff, Isabelle Schalk, Valérie Geoffroy
SummarySiderophores are organic chelators produced by microorganisms to fulfil
their iron requirements. Siderophore‐promoted dissolution of iron‐bearing
minerals has been clearly documented for some siderophores, but few studies have
addressed metabolizing siderophore‐producing bacteria. We investigated iron
acquisition from clays by fluorescent Pseudomonads, bacteria that are ubiquitous
in the en... hiện toàn bộ
Grazing affects methanotroph activity and diversity in an alpine meadow soil Tập 1 Số 5 - Trang 457-465 - 2009
Guy C. J. Abell, Nancy Stralis‐Pavese, Angela Sessitsch, Levente Bodrossy
SummaryThe role of methane‐oxidizing bacteria (MOB) in alpine environments is
poorly understood, but is of importance given the abundance of alpine
environments and the role of MOB in the global carbon cycle. Using a combination
of approaches we examined both seasonal and land usage effects on the ecology of
microbial methane oxidation in an alpine meadow soil. Analysis of the abundance
and divers... hiện toàn bộ
