Glanders Diagnosis in an Asymptomatic Mare from Brazil: Insights from Serology, Microbiological Culture, Mass Spectrometry, and Genome Sequencing.

ABSTRACT - This manuscript elucidates the occurrence of glanders in an asymptomatic mare from Brazil presenting positive Burkholderia mallei antibody titers. The diagnosis was established through a multi-pronged approach encompassing microbiological culture, mass spectrometry, and genome sequencing. The outbreak occurred in 2019 in Tatuí, São Paulo, Brazil, and the infected mare, despite displaying no clinical symptoms, had multiple miliary lesions in the liver, as well as intense catarrhal discharge in the trachea. Samples were collected from various organs and subjected to bacterial isolation, molecular detection, and identification. The strain was identified as B. mallei using PCR and confirmed by MALDI-TOF mass spectrometry. Whole-genome sequencing revealed a genome size of 5.51 Mb with a GC content of 65.8%, 5871 genes (including 4 rRNA and 53 tRNA genes), and 5583 coding DNA sequences (CDSs). Additionally, 227 predicted pseudogenes were detected. In silico analysis of different genomic loci that allow for differentiation with Burkholderia pseudomallei confirmed the identity of the isolate as B. mallei, in addition to the characteristic genome size. The BAC 86/19 strain was identified as lineage 3, sublineage 2, which includes other strains from Brazil, India, and Iran. The genome sequencing of this strain provides valuable information that can be used to better understand the pathogen and its epidemiology, as well as to develop diagnostic tools for glanders

A arqueologia dos fermentados: a etílica história dos Tupi-Guarani

O consumo de bebidas fermentadas é geralmente negligenciado pela literatura arqueológica, que trata a questão como tema de interesse secundário (recreativo) na história das populações humanas. Entretanto, a literatura etnográfica das sociedades indígenas das terras baixas sul-americanas indica exatamente o oposto: é o alimento vegetal sólido e não alcoólico que tende a possuir um papel secundário na vida cotidiana e ritualística de diversos coletivos. Os dados arqueológicos aprofundam temporalmente essa relação entre o ser humano e os fermentados. Além disso, os vasos cerâmicos arqueológicos utilizados para o preparo e consumo desses fermentados são fundamentais para a compreensão de processos e eventos históricos que modelaram a dispersão de uma série de grupos pelo continente

Innovation in UK independent homecare services : a thematic narrative review

This paper reports the findings of a thematic narrative review of peer-reviewed articles exploring innovation in UK independent homecare services published between January 2009–August 2021. Our analysis of 15 papers reveals four broad innovation types: personalised funding, operational models, workforce development and assistive technology. We conclude that research focused on innovation in independent homecare offers important insights into the positive and negative outcomes of different types of innovation for providers, care workers and people receiving care. There are, however, also areas which are neglected and need further elaboration, including more robust evidence of outcomes and clearer articulation of innovation processes
