Brucellosis is considered a common bacterial zoonotic disease of high prevalence in countries of the Middle East and the Mediterranean region with economic and public health impact. The present study aimed to investigate the current situation of brucellosis in small ruminants reared in Médéa and Sidi Bel-Abbès provinces, north Algeria. To achieve this objective, 96 sera (77 sheep and 19 goat) and 57 milk (42 sheep and 15 goat) samples were collected from suspected infected animals and serologically analyzed by using ELISA.

Background: Staphylococcus aureus is one of the most common pathogens that colonizes human skin/mucous membranes, where it causes local infection that can progress to invasive infection, resulting in high morbidity and mortality worldwide. This study aimed to investigate the antibiotic susceptibility and molecular characteristics of invasive S. aureus in children and women in Southwest China from 2018 to 2023 to provide novel insights helpful in preventing and treating S.

An approach combining enzymatic inhibition and untargeted metabolomics through molecular networking was employed to search for human recombinant full-length protein tyrosine phosphatase 1B (PTP1 B) inhibitors from a collection of 66 mangrove-associated fungal taxa. This strategy prioritized two strains (IQ-1612, section , and IQ-1620, section ) for further studies. Chemical investigation of strain IQ-1612 resulted in the isolation of a new nonanolide derivative, roseoglobuloside A (1: ), along with two known metabolites (2: and 3: ), whereas strain IQ-1620 led to the isolation of four known naphtho-γ-pyrones and one known diketopiperazine (4: -8: ).
