Emerging Mycobacterium bovis in Lebanon: a snapshot based on whole-genome sequencing.

The paper uses whole-genome sequencing to analyze Mycobacterium tuberculosis complex isolates from Lebanon, identifying M. tuberculosis lineages and M. bovis clades.

Pre-Columbian treponemes clarify worldwide spread of treponematosis

The paper identifies ancient Treponema pallidum strains in pre-Columbian remains, showing pre-Columbian Americas as the source of worldwide treponematosis spread.

Resuscitating Sleeping Beauties: reviving a six-hundred-year-old amoeba and endosymbiont.

This study revives a 600-year-old Acanthamoeba castellanii strain and its endosymbiont from coprolites, revealing their genomic features and survival mechanisms.

Dental pulp metagenomics reveals ancient human Herpesviridae.

The paper uses metagenomic sequencing of ancient DNA from dental pulp to detect herpesviridae genomes in historical human remains.

Matrix-assisted laser desorption ionization time-of-flight mass spectrometry identification of methanogens of clinical interest.

This study improves MALDI-TOF-MS for identifying methanogens from clinical samples, achieving high accuracy with reference spectra from cultured isolates.

Dairy products as sources of methanogens for humans

This study identifies methanogens in dairy products, showing that fermented products contain them more frequently than unfermented ones, suggesting dairy as a potential source for human gut methanogens.

Investigation of skin microbiota reveals Mycobacterium ulcerans-Aspergillus sp. trans-kingdom communication

The paper investigates skin microbiota in individuals exposed to Mycobacterium ulcerans and finds associations between M. ulcerans carriage and specific fungal species, suggesting potential trans-kingdom interactions.

Speciation of the Mycobacterium tuberculosis complex using mass spectrometry: a proof-of-concept.

This study demonstrates the use of MALDI-TOF-MS for species-level identification of Mycobacterium tuberculosis complex pathogens, achieving 95% accuracy compared to whole genome sequencing.

Geographic microevolution of Mycobacterium ulcerans sustains Buruli ulcer extension, Australia

This study identifies geographic microevolution of Mycobacterium ulcerans clones associated with severe Buruli ulcer cases in South Australia.

Experimental pieces of evidence for Mycobacterium ulcerans dormancy.

This study investigates whether Mycobacterium ulcerans exhibits dormancy using a Wayne model, finding that some strains show dormancy-like characteristics through microscopy, microcalorimetry, and subculture.

Stool methanogens in intestine mammal species.

This study identifies methanogen species in fecal samples from nine mammalian species, finding some human-associated methanogens in animals and suggesting potential zoonotic transmission.

Human dental pulp stem cells: a sanctuary for relapsing Bartonella quintana.

The paper identifies human dental pulp stem cells as potential long-term reservoirs for Bartonella quintana, based on their ability to internalize the bacteria without affecting cell proliferation.

Screening anti-infectious molecules against Mycobacterium ulcerans: a step towards decontaminating environmental specimens.

The paper tests anti-infectious molecules against M. ulcerans to identify ineffective ones for decontaminating environmental specimens.

Five millennia of Bartonella quintana bacteremia.

This study detects Bartonella quintana DNA in ancient human teeth to assess its prevalence across historical periods and populations.

A 2,000-year-old specimen with intraerythrocytic Bartonella quintana

The paper identifies Bartonella quintana in ancient blood cells preserved in dental pulp from a 2,000-year-old Roman individual using microscopy and molecular techniques.

Translocating Mycobacterium ulcerans: an experimental model.

This study shows that M. ulcerans can be detected in the feces and lymphatic system of rats after oral challenge, suggesting a potential role for herbivorous mammals in transmitting the pathogen without systemic infection.

Mycolactone-independent pathogenicity of Mycobacterium ulcerans: an experimental study in plants.

This study shows M. ulcerans can cause plant disease without mycolactones, using an experimental model with tomato plants.

Culture of salivary methanogens assisted by chemically produced hydrogen

The paper develops a chemical method to produce hydrogen for methanogen culture, showing faster growth compared to a biological method, though with lower colony counts in saliva samples.

Mycobacteria fecal shedding in wild boars (Sus scrofa), South-eastern France

The study investigates mycobacterial fecal shedding in wild boars in southeastern France, finding no tuberculosis agents but identifying non-tuberculous mycobacteria in 5.05% of samples.
