Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Microbial biomarkers as indicators of sperm viability in an insect

open access: yesRoyal Society Open Science
Our understanding of microbial variation in male reproductive tissues is poorly understood, both regarding how it varies spatially across different tissues and its ability to affect male sperm and semen quality. To redress this gap, we explored the relationship between male sperm viability and male gut and reproductive tract ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

The Healthy Human Blood Microbiome: Fact or Fiction?

open access: yesFrontiers in Cellular and Infection Microbiology, 2019
The blood that flows perpetually through our veins and arteries performs numerous functions essential to our survival. Besides distributing oxygen, this vast circulatory system facilitates nutrient transport, deters infection and dispenses heat ...

Dynamics of Microbial Indicators in Waste Water

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Agriculture, 2017
Water ecosystems are constantly under the pressure of a high number of biotic and abiotic factors, and their action leads to the occurrence of fluctuations in species and populations. The specific response of organisms to external pressures leads to the reorganization of ecosystems, with qualitative and quantitative changes.

Salmonella enterica serovar typhi limits the potency of typhoid toxin and ADP‐ribosylating toxin AB to establish a persistent infection

open access: yesFEBS Open Bio, EarlyView.
The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

Seeing the forest for the genes: using metagenomics to infer the aggregated traits of microbial communities [PDF]

open access: yes, 2014
Most environments harbor large numbers of microbial taxa with ecologies that remain poorly described and characterizing the functional capabilities of whole communities remains a key challenge in microbial ecology.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Supplementation of black pepper (Piper nigrum) in goats’ diet: influence on nutrient utilization and ruminal microbial characteristics

open access: yesActa Scientiarum: Animal Sciences
The use of phytogenic feed additives in livestock nutrition has gained increasing attention for their potential to improve rumen function and animal performance. Therefore, a 56-day study was conducted to assess the effects of black pepper (Piper nigrum)
