sp. nov., a Gram-Positive, Spore-Forming Rod Isolated from a Pharmaceutical Facility Production Environment and Added to the MALDI Biotyper Database.

A Gram-positive, aerobic, rod-shaped and spore-forming bacterium strain designation, B190/17, was isolated from an air monitoring sample of a Brazilian immunobiological production facility in 2017. The strain was not identifiable by biochemical methodology VITEK 2 or by MALDI-TOF MS with VITEK MS RUO and MALDI Biotyper. The 16S rRNA gene sequencing results showed 98.

Multifaceted modeling of small intestinal neuroendocrine tumors.

Small intestinal neuroendocrine tumors, siNETs, are a group of rare cancers that arise from neuroendocrine cells in the lining of the jejunum and ileum, which are either classified as tumors, siNETs, or small intestinal neuroendocrine carcinomas, siNECs. Current treatment strategies for low-grade tumors include surgical resection, peptide radionucleotide receptor therapy, and somatostatin analogues, while high-grade and recurrent tumors may receive cytotoxic chemotherapy. These limited treatment options are linked to the lack of representative models that can both reflect the biology of the tumor and are amenable to mid-to-high throughput experimentation.

Leveraging international stakeholders' experiences with oral PrEP costs to accelerate implementation of the monthly dapivirine vaginal ring: A qualitative study.

Background: Costing and financing systematic implementation are recognized barriers to human immunodeficiency virus (HIV) prevention. In the absence of empiric implementation and economic data, perspectives from international stakeholders involved in developing and supporting daily oral pre-exposure prophylaxis (PrEP) policy, and programs can provide critical insights for developing costed plans to support and accelerate the rollout of novel long-acting PrEP (LA-PrEP) methods, such as the monthly dapivirine vaginal ring (PrEP ring).

Methods: We interviewed stakeholders from purposively selected international organizations about anticipated PrEP-ring implementation costs, evidence gaps and key process steps for developing a costed rollout plan template (CRPT).

Multiplex Determination of K-Antigen and Colanic Acid Capsule Variants of .

is associated with the ingestion of contaminated reconstituted powdered infant formula (PIF), resulting in necrotizing enterocolitis, sepsis and meningitis in neonatal infants. Potential virulence determinants include the variable capsular polysaccharides; K-antigen and colanic acid (CA). Strains encoding for the capsule variant K2:CA2 have been strongly associated with neonatal meningitis cases.

Establishment of a Reference Material in Quality Control for Use in Infectivity and Identity Assays of Recombinant COVID-19 Vaccine, in Accordance with International Standards Organization Guidance.

The COVID-19 pandemic, caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), began in 2019. One of the strategies for pandemic control was mass vaccination. In Brazil, the recombinant COVID-19 vaccine (RCV) was produced on a large scale and offered at no charge to the population.
