Screening of bacterial molecules with antagonistic or adjuvant activity [PDF]

, 2010
The Lipopolysaccharides (LPSs) are the major constituents of the outer membrane of Gram-negative bacteria and the interest in their chemical characterization is motivated by the close correlation existing between the structure and the biological activity

Prevalence and antimicrobial susceptibility of Acinetobacter spp. isolated from meat

, 2017
The prevalence and antibiotic resistance of Acinetobacter spp. from fifty samples of meat (chicken, turkey, beef and pork) were evaluated. Acinetobacter spp.

IgE‐Binding Bacterial Components Not Yet Documented in the Allergen Databases and Their Allergenic Mechanisms: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Among bacteria that are associated with the development and/or exacerbation of allergic/atopic diseases, several have been described to produce IgE‐binding components. However, only one bacterial protein, Bac s 1, is currently listed in the official database of the World Health Organization/International Union of Immunological Societies (WHO ...

Diverse responses to UV light exposure in Acinetobacter include the capacity for DNA damage-induced mutagenesis in the opportunistic pathogens Acinetobacter baumannii and Acinetobacter ursingii

, 2012
Error-prone and error-free DNA damage repair responses that are induced in most bacteria after exposure to various chemicals, antibiotics or radiation sources were surveyed across the genus Acinetobacter.

Antimicrobial Resistance in Children With Bloodstream Infections: A Population‐Based Study in Stockholm, Sweden

Acta Paediatrica, EarlyView.
ABSTRACT Aim We retrospectively evaluated trends in antimicrobial resistance (AMR) in paediatric bloodstream infections and assessed changes in antimicrobial prescription patterns over a 20‐year period. Methods We analysed positive blood cultures from children admitted with suspected serious infection between 1998 and 2018.

Accurate identification of clinically important Acinetobacter spp.: an update

, 2019
Acinetobacter species have emerged as one of the most clinically important pathogens. The phenotypic techniques which are currently available are insufficient in accurately identifying and differentiating the closely related and clinically important ...

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Catalysis and allostery in bacterial ATP phosphoribosyltransferases

The FEBS Journal, EarlyView.
ATP phosphoribosyltransferase (ATPPRT) catalyses the first reaction of L‐histidine biosynthesis. L‐Histidine allosterically inhibits ATPPRT to regulate this energy‐intensive pathway in histidine‐synthesising organisms, such as bacteria, archaea and plants.

A guide to host genetic determinants of female microbiome composition across distinct anatomical niches

The FEBS Journal, EarlyView.
Host genetic variation in immune regulation and cell signalling genes was associated with microbiome composition across vaginal, gut, oral and skin sites, while associations involving metabolic function, epithelial barrier integrity and hormonal processes were more site‐specific. Overall, our findings indicate that host genetic variation contributes to
