Bezlotoxumab as Treatment for Recurrent/Chronic Clostridioides difficile Infection in Pediatric Stem Cell Transplant Recipients: A Multi‐Institutional Experience

Pediatric Blood &Cancer, Volume 72, Issue 10, October 2025.
ABSTRACT Clostridioides difficile infection (CDI) represents a significant health risk to pediatric stem cell transplant (SCT) patients. In these patients, recurrent CDI is common, requiring prolonged antibiotic usage and increased hospitalization. Bezlotoxumab, a monoclonal antibody that targets the toxin responsible for CDI, has demonstrated efficacy

Daily HIV pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate-emtricitabine reduced Streptococcus and increased Erysipelotrichaceae in rectal microbiota. [PDF]

, 2018
Daily PrEP is highly effective at preventing HIV-1 acquisition, but risks of long-term tenofovir disoproxil fumarate plus emtricitabine (TDF-FTC) include renal decline and bone mineral density decrease in addition to initial gastrointestinal side effects.

A MXene‐Based Nanothermal Knife Inhibits Aggresome‐Mediated Persister Formation for Preventing Dental Caries

Advanced Science, Volume 12, Issue 33, September 4, 2025.
Early childhood caries (ECC) involves cariogenic persisters that evade antimicrobial treatment. Persisters achieve this by downregulating heat shock proteins (HSPs) and formation of protein aggregates. Ti3C2 MXene‐based photothermal therapy (PTT) acts as a “nanothermal knife,” disrupting membranes, upregulating HSPs, inhibits aggregates, prevents ...

Supragingival Microbiota Alterations in Individuals With Sleep Bruxism: A Pilot Study

Journal of Oral Rehabilitation, Volume 52, Issue 9, Page 1319-1327, September 2025.
ABSTRACT Background Sleep bruxism (SB) is an oral behaviour associated to jaw clenching or grinding of the teeth. Its aetiology is most likely multifactorial; however, recent studies suggested that SB is associated with activation of the sympathetic nervous system. Dysbiosis of the oral microbiota is linked to oral and systemic diseases.

Regulation of Synthesis of  -Fructofuranosidase (Invertase) in Streptococcus mitis

Microbiology, 1980
beta-Fructofuranosidase activity was found to be cell-bound in Streptococcus mitis ATCC 903. The following evidence suggests that induction functions as a regulatory mechanism for beta-fructofuranosidase in S. mitis: (1) on transfer of glucose-grown exponential phase bacteria to sucrose medium, the specific activity of beta-fructofuranosidase increased
