Introduction: Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.
Methodology: We report a case of a 43-year-old man who was admitted to our hospital for further management of severe coronavirus disease 2019 (COVID-19) pneumonia.

Rheumatoid arthritis (RA) is a complex autoimmune disease with growing evidence implicating the microbiota as a critical contributor to its pathogenesis. This review explores the multifaceted roles of microbial dysbiosis in RA, emphasizing its impact on immune cell modulation, autoantibody production, gut barrier integrity, and joint inflammation. Animal models reveal how genetic predisposition and environmental factors interact with specific microbial taxa to influence disease susceptibility.

Biofilms are complex adhesive structures that establish chronic infection and allow robust protection from external stressors such as antibiotics. Cellulose as one of the compositions of bacteria biofilm which protect bacteria from stress, host immune responses and resistance to antibiotics. Bacterial stress responses are regulated via guanosine pentaphosphate and tetraphosphate (p)ppGpp.

Colibacillosis is a disease caused by avian pathogenic Escherichia coli (APEC) isolates which results in significant morbidity and mortality in poultry, as well as in economic loses. In order to identify APEC strains in a population of 898 E. coli isolates from poultry samples collected from different avian flocks located in the Valencian Region, Spain, we analysed the most significantly related to highly-pathogenic colibacillosis virulence-associated genes (VAGs) (hlyF, iroN, iss, iutA and ompT) by multiplex real-time polymerase chain reaction (RT-PCR).
