Temporal variability of human vaginal bacteria and relationship with bacterial vaginosis.

PLoS ONE, 2010
BackgroundLittle is known about short-term bacterial fluctuations in the human vagina. This study used PCR to assess the variability in concentrations of key vaginal bacteria in healthy women and the immediate response to antibiotic treatment in women ...

Need for Susceptibility Testing Guidelines for Fastidious or Less-Frequently Isolated Bacteria [PDF]

Journal of Clinical Microbiology, 2004
In the United States, clinical microbiology laboratories rely upon the National Committee for Clinical Laboratory Standards (NCCLS) for written standards that guide the important elements of antimicrobial susceptibility testing. Whether a laboratory performs a direct version of an NCCLS standard method (e.g., disk diffusion) or uses a commercial device

Improved culture of fastidious Gemmata spp. bacteria using marine sponge skeletons [PDF]

Scientific Reports, 2019
AbstractGemmata are Planctomycetes bacteria recalcitrant to traditional cultivation in the clinical microbiology laboratory and they have been seldom documented in patients. Based on previously known relationships of Planctomycetes with marine sponges, we designed a new culture medium A incorporating marine sponge skeleton of Spongia sp.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

FEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Screening of diverse Psylloidea species in Taiwan reveals the presence of both known and potentially novel “Candidatus Liberibacter” species in multiple psyllid lineages

Microbiology Spectrum
Psyllids (Psylloidea) are host-specific, phloem-feeding insects that are associated with the transmission of destructive plant diseases caused by the bacterial genus “Candidatus Liberibacter”.

Isolation, cultivation, and in vitro susceptibility testing of Borrelia burgdorferi sensu lato: A review [PDF]

Archives of Biological Sciences, 2013
Lyme borreliosis is the most common vector-borne disease in the northern hemisphere. The agents of Lyme borreliosis are borrelia, bacteria of the family Spirochaetaceae, which are grouped in Borrelia burgdorferi sensu lato species complex.

Assessment of the adaptability of non-fastidious pathogenic bacteria to the Martian environment. [PDF]

, 2021
Understanding the extent to which non-fastidious pathogenic bacteria can survive in extraterrestrial conditions will help to guarantee the safety of astronauts. Despite stringent decontamination protocols, terrestrial microorganisms were previously found to travel on the bodies of astronauts, on spaceships and equipment.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
