Occurrence and ecological determinants of the contamination of floodplain wetlands with Klebsiella pneumoniae and pathogenic or antibiotic-resistant Escherichia coli

The survival and multiplication of human pathogenic and antibiotic-resistant bacteria in ecosystems is of increasing concern but has been little explored. Wetlands can be contaminated by water fluxes from rivers and may present environmental conditions lea ...

Synergy and remarkable specificity of antimicrobial peptides in vivo using a systematic knockout approach

Bruno Lemaitre, Camilla Carla Alma Ceroni, Mark Austin Hanson, Anna Dostalova

Antimicrobial peptides (AMPs) are host-encoded antibiotics that combat invading microorganisms. These short, cationic peptides have been implicated in many biological processes, primarily involving innate immunity. In vitro studies have shown AMPs kill bac ...

Using NanoSIMS coupled with microfluidics to visualize the early stages of coral infection by Vibrio coralliilyticus

Anders Meibom, Isabelle Domart-Coulon, Emma Mary Gibbin

Background: Global warming has triggered an increase in the prevalence and severity of coral disease, yet little is known about coral/pathogen interactions in the early stages of infection. The point of entry of the pathogen and the route that they take on ...

Characterization of antibiotic multi-resistant bacteria and resistance genes in the effluent of an intensive shrimp farm (Long An, Viet Nam)

Pierre Rossi, Luiz Felippe De Alencastro

Emergence of antibiotic resistant (AR) bacteria and antibiotic resistance genes (ARGs) in the aquaculture industry is a growing issue for human health. Shrimp farmers in Viet Nam have free access to and make use of a wide variety of antibiotics to treat di ...

The dual oxidase gene BdDuox regulates the intestinal bacterial community homeostasis of Bactrocera dorsalis

Bruno Lemaitre

The guts of metazoans are in permanent contact with the microbial realm that includes beneficial symbionts, nonsymbionts, food-borne microbes and life-threatening pathogens. However, little is known concerning how host immunity affects gut bacterial commun ...

XacFhaB adhesin, an important Xanthomonas citri ssp citri virulence factor, is recognized as a pathogen-associated molecular pattern

Luciano Andres Abriata

Adhesion to host tissue is one of the key steps of the bacterial pathogenic process. Xanthomonas citri ssp. citri possesses a non-fimbrial adhesin protein, XacFhaB, required for bacterial attachment, which we have previously demonstrated to be an important ...

An intracellular replication niche for Vibrio cholerae in the amoeba Acanthamoeba castellanii

Melanie Blokesch, Catherine Maclachlan, Tiziana Scrignari, Charles Ulric V Van der Henst

Vibrio cholerae is a human pathogen and the causative agent of cholera. The persistence of this bacterium in aquatic environments is a key epidemiological concern, as cholera is transmitted through contaminated water. Predatory protists, such as amoebae, a ...

Inactivation kinetics and mechanisms of viral and bacterial pathogen surrogates during urine nitrification

Tamar Kohn, Ariane Schertenleib, Kai Udert

This paper assesses the inactivation performance and mechanisms in urine nitrification reactors using bacteria and bacteriophages as surrogates for human pathogens. Two parallel continuous-flow moving bed biofilm reactors (MBBRs) were operated over a two-m ...

Overexpression of the tcp Gene Cluster Using the T7 RNA Polymerase/Promoter System and Natural Transformation-Mediated Genetic Engineering of Vibrio cholerae

Melanie Blokesch

The human pathogen and aquatic bacterium Vibrio cholerae belongs to the group of naturally competent bacteria. This developmental program allows the bacterium to take up free DNA from its surrounding followed by a homologous recombination event, which allo ...

Genome-wide comparison of medieval and modern Mycobacterium leprae

Stewart Cole, Andrej Benjak, Philippe Busso, Pushpendra Singh

Leprosy was endemic in Europe until the Middle Ages. Using DNA array capture, we have obtained genome sequences of Mycobacterium leprae from skeletons of five medieval leprosy cases from the United Kingdom, Sweden, and Denmark. In one case, the DNA was so ...
