A case of melioidosis with a mycotic aneurysm is reported. The blood and tissue isolates were identified as three different species of Burkholderia using the automated identification systems, VITEK 2 and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The isolate was confirmed as Burkholderia pseudomallei by 16S rRNA sequencing. The typical features of the Gram staining of colonies and 16S rRNA sequencing can be useful to identify B. pseudomallei.

Our understanding of the basic relationships of microbiota associated with flowers is still quite limited, especially regarding parasitic plant species. The transient nature of flower parts such as pistil stigmas provides a unique opportunity for temporal investigations. This is the first report of the analysis of bacterial and fungal communities associated with the pistil stigmas of the lucerne parasite, Orobanche lutea.

Propidium monoazide (PMA) is a dye that distinguishes between live and dead cells in molecular assays like the Polymerase Chain Reaction (PCR). It works by cross-linking to the DNA of cells that have compromised membranes or extracellular DNA upon photoactivation, making the DNA inaccessible for amplification. Currently, PMA is used to detect viable pathogens and alleviate systemic bias in the microbiome analysis of samples using 16S rRNA gene sequencing.

Objectives: Faecal microbiota transplantation (FMT) is an established treatment for recurrent Clostridioides difficile infection (R-CDI). This study aimed to identify calprotectin and microbiome characteristics as potential biomarkers of FMT success.
Methods: We conducted a prospective study of patients who underwent oral FMT (single dose of 4-5 capsules) for R-CDI (January 2018 to December 2022).

The negative effects associated with cyanobacterial blooms are of particular concern in protected ecosystems, as these areas are ecologically significant and attract a high number of visitors. This study aims to explore the cyanobacterial communities and associated toxicity in three reservoirs located within a Mediterranean National Park with a compromised situation at basin-level. Our results demonstrate the occurrence of dense toxic blooms containing microcystins (reaching values close to 280 μg L) and low levels of anatoxin-a and saxitoxins (up to 0.
