Umbodinia bella gen. nov. et sp. nov. is described and illustrated from specimens collected in the canopy of an ombrophilous Amazonian forest, Manaus, Brazil. The genus is characterized by a unique combination of diagnostic features: body predominantly yellow; frons with two shiny dark brown to black lobules in lower corners, between the lunule and eye margins; lunule high-arched with two subtriangular spots covered with black pubescence; parafacial with tufts of long and strong setae, almost as long and stout as the fronto-orbital setae; and anepisternum with setulae dorsally and posteriorly, in addition to posterior setae.

Background: Canola essential oil (CEO) contains linoleic and oleic fatty acids that can inhibit the growth of pathogenic micro-organisms and alter microbial digestion to increase ruminal fermentation and nutrient utilisation.
Objectives: The study evaluated the effect of supplementing a basal goat diet with incremental doses of CEO on chemical constituents and in vitro ruminal fermentation parameters and microbial diversity.
Methods: Experimental treatments were a basal goat diet containing 0.

This work aims to (1) identify microbial and metabolic alterations and (2) reveal a shift in phenylalanine production-consumption equilibrium in individuals with HIV. We conducted extensive searches in multiple databases [MEDLINE, Web of Science (including Cell Press, Oxford, HighWire, Science Direct, IOS Press, Springer Nature, PNAS, and Wiley), Google Scholar, and Embase] and selected two case-control 16S data sets (GenBank IDs: SRP039076 and EBI ID: ERP003611) for analysis. We assessed alpha and beta diversity, performed univariate tests on genus-level relative abundances, and identified significant microbiome features using random forest.

Background: Multidrug-resistant strains of the genus can produce various β-lactamases that confer resistance to a broad spectrum of β-lactams, which poses a significant public health threat due to their emergence and spread in clinical settings and natural environments. Therefore, a comprehensive investigation into the antibiotic resistance mechanisms of is scientifically significant.
Methods: Between 2018 and 2021, 78 clinical isolates were collected from human clinical specimens.

Background: Heterorhabditis are important biological control agents in agriculture. Two Heterorhabditis populations, S8 and S10, were isolated from agricultural soils in the United States of America. Molecular analyses, based on mitochondrial and nuclear genes, showed that these populations are conspecific and represent a novel species of the "Bacteriophora" clade.
