Thirty-one Acinetobacter baumannii strains, comprising 14 strains from 14 outbreaks in different northwestern European cities and 17 sporadic strains, were compared by investigating various properties of the strains including biotype, antibiogram, cell envelope protein electrophoretic profile, ribotype pattern, and the band pattern generated by a novel genomic fingerprinting method, named AFLP,...

In the title compound, C(19)H(13)N(5)·C(4)H(8)O(2)·2H(2)O, the mol-ecular skeleton of the 2,6-bis-(benzimidazol-2-yl)pyridine (bbip) mol-ecule is essentially planar (r.m.s. deviation = 0.023 Å). An extensive three-dimensional network of inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds consolidates the crystal packing, which also exhibits π-π inter-actions between the five- and six-membered...

The functional helper T cell line Vir-2, derived from a PR8 (H1N1) influenza virus-immunized BALB/c mouse, proliferates in response to syngeneic antigen-presenting cells and naturally occurring strains of subtype H1 human influenza virus from 1934-1957 and 1977-1980 isolates. A conserved region of the hemagglutinin molecule around amino acid position 115 in the heavy chain (HA1) was implicated ...

The lactic acid bacterium Oenococcus oeni, mainly responsible for malolactic fermentation (MLF), is used in new winery process as starter culture for direct inoculation. The difficulty to master MLF according to the wine led us to search a new approach to select effective O. oeni strains. Biochemical and molecular tests were performed in order to characterize three strains of O. oeni selected f...

In dialogues in which both agents are autonomous, each agent deliberates whether to accept or reject the contributions of the current speaker. A speaker cannot simply assume that a proposal or an assertion will be accepted. However, an examination of a corpus of naturally-occurring problem-solving dialogues shows that agents often do not explicitly indicate acceptance or rejection. Rather the s...

The ability of Aspergillus niger strains to support citric acid production using solid-state fermentation agricultural processing coproducts was examined in this review. Citric has been shown have a number commercial applications the food and beverage industries. A. capable elevated are known contain genetic mutations that stimulate overproduction organic likely involving cycle reactions. previ...

Of 158 oral Streptococcus milleri strains, 46 exhibited cellular coaggregation with the reagent strains of the actinomyces coaggregation groups A, B, and/or E. All but 1 of the 33 serotype b, e, f/F, and k/G strains belonged to streptococcus coaggregation group 2, and only 14 strains of limited seroclasses (g, i, Lancefield group F, or untypeable) appeared to be members of group 5, 3, or 4 (10,...
