Inhibition of Zika virus by Wolbachia in Aedes aegypti
Eric Pearce Caragata, Heverton Leandro Carneiro Dutra and Luciano Andrade Moreira
This article comments on work published by Dutra et al. (Cell Host Microbe, 2016), which investigated the potential of Wolbachia infections in Aedes aegypti to restrict infection and transmission of Zika virus.
Syphilis: Re-emergence of an old foe
Lola V. Stamm
Syphilis is caused by infection with Treponema pallidum subsp. pallidum, a not-yet-cultivable spiral-shaped bacterium that is usually transmitted by sexual contact with an infected partner or by an infected pregnant woman to her fetus. This review provides insights into the etiology, epidemiology, clinical manifestation, diagnosis, treatment and prevention of syphilis.
Trichomoniasis – are we giving the deserved attention to the most common non-viral sexually transmitted disease worldwide?
Camila Braz Menezes, Amanda Piccoli Frasson, Tiana Tasca
Trichomonas vaginalis is the etiologic agent of trichomoniasis, the most common non-viral sexually transmitted disease (STD) in the world. This article contributes to claim the attention of public health policies to control this STD.
House of cellulose – a new hideout for drug tolerant Mycobacterium tuberculosis
Ashwani Kumar
This article comments on work published by Trivedi et al. (Nat Commun, 2016), which shows that Mycobacterium tuberculosis cells organise themselves into biofilms in response to intracellular thiol reductive stress.
Antibiotic use in childhood alters the gut microbiota and predisposes to overweight
Katri Korpela and Willem M de Vos
This article comments on work published by Korpela et al. (Nat Commun, 2016), which investigates the correlation between the use of antibiotics in early life and the excessive weight gain in later childhood.
Evidence for the hallmarks of human aging in replicatively aging yeast
Georges E. Janssens, Liesbeth M. Veenhoff
Recently, efforts have been made to characterize the hallmarks that accompany and contribute to the phenomenon of aging, as most relevant for humans. Remarkably, studying the finite lifespan of the single cell eukaryote budding yeast has been paramount for our understanding of aging. Here, we compile observations from literature over the past decades of research on replicatively aging yeast to highlight how the hallmarks of aging in humans are present in yeast.
Bacterial outer membrane vesicle biogenesis: a new mechanism and its implications
Sandro Roier, Franz G. Zingl, Fatih Cakar, and Stefan Schild
This article comments on work published by Roier et al. (Nat Commun, 2016), which proposes a novel and highly conserved bacterial outer membane vesicle biogenesis mechanism based on phospholipid accumulation in the outer leaflet of the outer membrane.
A plant Bcl-2-associated athanogene is proteolytically activated to confer fungal resistance
Mehdi Kabbage1, Ryan Kessens1 and Martin B. Dickman2
This article comments on work published by Li et al. (Plant Cell, 2016), which focuses on the role of Bcl-2-associated athanogene 6 (BAG6) in plant innate immunity, showing that BAG6 plays a key role in basal plant defense against fungal pathogens.
Adaptive bacterial response to low level chlorhexidine exposure and its implications for hand hygiene
March 7, 2019
This article shows that bacteria can adapt to low levels of Chlorhexidine digluconate (CHG), resulting in increased tolerance and cross-resistance to other antimicrobials, suggesting caution in the widespread use of CHG to minimize avoidable selection pressure for resistance.
Microevolution of the pathogenic yeasts Candida albicans and Candida glabrata during antifungal therapy and host infection
February 8, 2019
This review explores how Candida albicans and Candida glabrata, common fungal pathogens resistant to antifungal therapy, adapt and evolve within different environments, aiming to identify stable adaptive mechanisms as potential drug targets.
The extracellular matrix of mycobacterial biofilms: could we shorten the treatment of mycobacterial infections?
January 18, 2019
The article discusses the challenges presented by biofilms formed by non-tuberculous mycobacteria (NTM) species, which can lead to persistent infections that are difficult to treat due to phenotypic drug tolerance. The role of various cell wall components in mycobacterial biofilm formation is outlined, with a particular focus on Mycobacterium tuberculosis.
Guidelines for DNA recombination and repair studies: Cellular assays of DNA repair pathways
January 7, 2019
DNA recombination, repair and mutagenesis assays are powerful tools but each comes with its particular advantages and limitations. Here the most commonly used assays are reviewed, discussed, and presented as the guidelines for future studies.
Guidelines for DNA recombination and repair studies: Mechanistic assays of DNA repair processes
January 7, 2019
Mechanistic assays of DNA repair processes are a powerful tools but each comes with its particular advantages and limitations. Here the most commonly used assays are reviewed, discussed, and presented as the guidelines for future studies.
Pathways of host cell exit by intracellular pathogens
October 18, 2018
This review provides an overview of the diverse host cell exit strategies employed by intracellular-living bacterial, fungal, and protozoan pathogens, highlighting the commonalities and system-specific variations of these strategies, and discussing potential microbial molecules involved in host cell exit as targets for future intervention approaches.
Protective roles of ginseng against bacterial infection
September 19, 2018
This review highlights the antibacterial effects of ginseng against pathogenic bacterial infections, discussing its regulation of pathogenic factors and proposing the therapeutic potential of ginseng as a natural antibacterial drug to address antibiotic resistance and toxicity in the context of global public health challenges.
A Cinderella story: how the vacuolar proteases Pep4 and Prb1 do more than cleaning up the cell’s mass degradation processes
September 18, 2018
This review summarizes the expanded roles of the Saccharomyces cerevisiae vacuolar proteases Pep4 and Prb1 in non-vacuolar activities outside of autophagy, such as programmed cell death, protection from harmful protein forms, and gene expression regulation. The potential implications of these findings for fungal biology and drug target discovery, including insights for mammalian cell studies, are highlighted, emphasizing the need for a deeper understanding of these molecular processes.
The biosynthesis of pyoverdines
August 28, 2018
This review provides an overview of pyoverdine biosynthesis, emphasizing the distinctive fluorophore shared by various pyoverdines derived from ferribactins and the role of periplasmic processes in the maturation and modification of these siderophores, critical for the growth and colonization of hosts by fluorescent pseudomonads.
