Summary: This study compared classical microbiological methods with MALDI-TOF MS in fungi identification, showing that MALDI-TOF MS is an effective alternative, especially for HIV-positive patients, due to the different morphology of fungal colonies.

Summary: This study reports the first isolation of C. calyptogenae from human oral samples. The ability of C. calyptogenae to grow at 37 degrees Celsius and its presence as the only yeast species isolated from the patient's oral samples suggests its potential role in angular cheilitis.

Summary: Candida colonisation in the oral cavity is increased in immunocompromised individuals, leading to the development of oral candidiasis. Various host factors can accelerate the disease process. Candida albicans is the main pathogenic agent due to its ability to form biofilm and hyphae, and produce hydrolytic enzymes and candialysin. Prevention of infection can be achieved through addressing host physiological factors and habits.

Summary: The oral cavity is a diverse ecosystem with a variety of microorganisms, and a study was conducted to compare the bacterial fauna of healthy and non-healthy dental samples. The research revealed that while the bacterial strain diversity was similar between the two types of ecosystems, there were differences in bacteriocin production.

Summary: This study found a close correlation between hydrogen sulfide (H2S) concentration and oral microorganism activity. The high H2S group showed a different microbial taxonomy compared to the low H2S group. Most of the enriched microorganisms in the high H2S group were associated with oral diseases.

Summary: The study identified Candida albicans as the causative pathogen of goose oesophageal ulcers, which showed high morbidity and mortality rates in infected geese. The genetic analysis revealed close relationship between goose-origin C. albicans strains and human-origin isolates, indicating potential zoonotic transmission. The independent evolution of goose-origin C. albicans strains suggests a unique population dynamic, providing important insights for public health and safety measures.

Summary: This study reports the first documentation of Candida oceani isolated from human skin punch biopsy. Susceptibility testing showed good activity of common clinical antifungals against the isolate. Whole genome sequencing was performed to provide a draft genome of C. oceani.

Summary: This study aims to investigate the association between different smoking methods (cigarette, hookah, and electronic smoking) and denture stomatitis caused by oral Candida spp. It also explores the dose-response relationship between smoking duration and the probability of denture stomatitis. The results show that smoking has a significant impact on oral health and is positively associated with oral Candida infection. Furthermore, chronic diseases may serve as systemic predisposing factors for oropharyngeal infection.

Summary: Helicobacter pylori is primarily transmitted through the oral-oral route and fecal-oral route, with the oral cavity hypothesized as an extragastric reservoir. H. pylori in the oral cavity may contribute to periodontitis, various oral diseases, gastric eradication failure, and reinfection. Understanding the survival strategies of H. pylori in the oral cavity is critical for the prevention and treatment of infection.

Summary: This study revealed that infection of C. tropicalis in sows through gastrointestinal mucosa could cause fatal digestive system disease and septicemia. A strain of C. tropicalis was isolated and identified from the gastric tissue of sows with severe gastrointestinal diseases for the first time. PCR and sequencing of ITS-rDNA combined with morphology and histopathological assay were reliable for the identification of Candida clinically.

Summary: The aim of the study was to find an effective bio-based strategy for whitewater treatment by selecting indigenous bacterial isolates. A consortium of four strains was identified that could degrade the entire spectrum of tested additives, leading to an 88% reduction in COD of the whitewater in a pilot scale study.

Summary: This study analyzed the bacteriostatic effects of Chinese herbal medicine on Candida glabrata. It was found that Cortex phellodendri and Sophora flavescens had the strongest inhibitory effects on C. glabrata growth. These herbal medicines are expected to be used to treat fungal infections in poultry in the future.

Summary: This study describes the epidemiology of non-albicans Candida (NAC) infections and their resistance in Lebanese hospitals. The most common NAC species isolated were Candida glabrata (40.8%) and Candida tropicalis (23.1%). The study also found differing susceptibility to antifungal treatments among these species. Proper identification of these organisms is crucial for effective treatment.

Summary: This study aimed to identify yeast isolates from the oral cavity of healthy cats and evaluate their antifungal susceptibility pattern. The results showed that cats have a different oral mycoflora compared to humans and other animals, but the susceptibility patterns are similar to those seen in isolates from other species. Further studies are needed to characterize the oral mycobiota of cats and its role in oral infections.

Summary: Oral candidiasis, a common opportunistic infection, is mainly caused by Candida species. This study provides in-depth Raman spectroscopy analyses and proposes a barcode-assisted Raman method for rapid identification of oral yeast species. The method can enable on-site identification and improve disease control.
