Several human fungal pathogens, including drug-resistant and species of the complex, have emerged over the past two decades, posing new threats to human health. In this study, we report the isolation and identification of a novel species belonging to the genus , herein named as , from a clinical sputum sample of a COVID-19 patient. is phylogenetically closely related to fungal pathogens (syn. ) and . When grown on CHROMagar Plus medium, exhibited a similar coloration to strain CBS12372. was able to develop weak filaments on CM medium. Although and are phylogenetically closely related, comparative genomic and synteny analyses indicated significant chromosomal rearrangements between the two species. Although could not grow at 37 °C under regular culture condition, an increased fungal burden in the lung tissue of a mouse systemic infection model implies that it could be a potential opportunistic pathogenic yeast in humans.

Rapamycin is an important natural macrolide antibiotic with antifungal, immunosuppressive and antitumor activities produced by Streptomyces rapamycinicus. However, their prospective applications are limited by low fermentation units. In this study, we found that the exogenous aromatic amino acids phenylalanine and tyrosine could effectively increase the yield of rapamycin in industrial microbial fermentation.

Fetal growth restriction (FGR) is a common complication of pregnancy, which seriously endangers fetal health and still lacks effective therapeutic targets. Clostridium difficile (C. difficile) is associated with fetal birth weight, and its membrane vesicles (MVs) are pathogenic vectors.

The human bowel is exposed to numerous biotic and abiotic external noxious agents. Accordingly, the digestive tract is frequently involved in malfunctions within the organism. Together with the commensal intestinal flora, it regulates the immunological balance between inflammatory defense processes and immune tolerance.

The ApxIVA protein belongs to a distinct class of a "clip and link" activity of Repeat-in-ToXin (RTX) exoproteins. Along with the three other pore-forming RTX toxins (ApxI, ApxII and ApxIII), ApxIVA serves as a major virulence factor of Actinobacillus pleuropneumoniae, the causative agent of porcine pneumonia. The gene encoding ApxIVA is located on a bicistronic operon downstream of the orf1 gene and is expressed exclusively under in vivo conditions.

Duck Tembusu virus (DTMUV), an emerging avian pathogenic flavivirus, is notably associated with neurological disorders and acute egg drop syndrome in ducks. We previously demonstrated that the susceptibility of ducks to DTMUV infection varies significantly with age, with younger ducks (4-week-old) exhibiting more severe disease than older ducks (27-week-old). However, the immunological mechanisms underlying these age-related differences in disease severity remain unclear.
