Abstract
OBJECTIVES This study aimed to determine the potency of hyperbaric oxygen therapy (HBOT) to the blood glucose level, amount of lymphocytes, and the expression of antibody anti-Candida in oral candidiasis diabetes mellitus. MATERIALS AND METHODS Thirty Wistar rats were divided into five groups: K1 normal-control group, while K2, P1, P2, and P3 were diabetes induced by streptozotocin 50 mg/kg body weight. Oral candidiasis was induced by inoculation 0.1 mL Candida albicans ATCC 10321 on dorsum of the tongue. P1 was given nystatin oral suspension, P2 was treated by HBOT 2.4 ATA, 3 × 30 minutes each with a 5-minute interval, and P3 was treated by the combination of nystatin and HBOT. All the treatments were performed for 5 consecutive days. Fasting blood glucose level was examined on glucometer strips, lymphocyte was examined from complete blood count, and the expression of antibody anti-Candida was examined on immunohistochemistry staining STATISTICAL ANALYSIS: Data analyzed by a one-way analysis of variance and least significant difference test with the result of p-value less than 0.05 was considered to be statistically significant. RESULTS HBOT reduced blood glucose level (p > 0.05) increased the amount of lymphocyte (p < 0.05). All treatments reduced the expression of antibody anti-Candida (p < 0.05) with the best result on combination of HBOT with nystatin. CONCLUSION HBOT decreased the blood glucose level, increased the amount of lymphocytes, and reduced the expression of antibody anti-Candida in oral candidiasis diabetes mellitus.

Front Vet Sci 2024; 11:1356819. [PMID: 38500605 PMCID: PMC10944897 DOI: 10.3389/fvets.2024.1356819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Accepted: 02/19/2024] [Indexed: 03/20/2024] Open
Abstract
Pseudorabies virus (PRV) can cause fatal encephalitis in newborn pigs and escape the immune system. While there is currently no effective treatment for PRV, Scutellaria baicalensis Georgi polysaccharides (SGP) and Rodgersia sambucifolia Hemsl flavonoids (RHF) are traditional Chinese herbal medicines with potential preventive and therapeutic effects against PRV infection. In order to explore which one is more effective in the prevention and treatment of PRV infection in piglets. We investigate the therapeutic effects of RHF and SGP in PRV-infected piglets using clinical symptom and pathological injury scoring systems. The immune regulatory effects of RHF and SGP on T lymphocyte transformation rate, cytokines, T cells, and Toll-like receptors were also measured to examine the molecular mechanisms of these effects. The results showed that SGP significantly reduced clinical symptoms and pathological damage in the lungs, liver, spleen, and kidneys in PRV-infected piglets and the T lymphocyte conversion rate in the SGP group was significantly higher than that in the other treatment groups, this potential dose-dependent effect of SGP on T lymphocyte conversation. Serum immunoglobulin and cytokine levels in the SGP group fluctuated during the treatment period, with SGP treatment showing better therapeutic and immunomodulatory effects in PRV-infected piglets than RHF or the combined SGP + RHF treatment. In conclusion, RHF and SGP treatments alleviate the clinical symptoms of PRV infection in piglets, and the immunomodulatory effect of SGP treatment was better than that of the RHF and a combination of both treatments. This study provides evidence for SGP in controlling PRV infection in piglets.

Abstract
Objective Gut fungi, as symbiosis with the human gastrointestinal tract, may regulate physiology via multiple interactions with host cells. The plausible role of fungi in systemic lupus erythematosus (SLE) is far from clear and need to be explored. Methods A total of 64 subjects were recruited, including SLE, rheumatoid arthritis (RA), undifferentiated connective tissue diseases (UCTDs) patients and healthy controls (HCs). Fecal samples of subjects were collected. Gut fungi and bacteria were detected by ITS sequencing and 16S rRNA gene sequencing, respectively. Alpha and beta diversities of microbiota were analyzed. Linear discriminant analysis effect size analysis was performed to identify abundance of microbiota in different groups. The correlation network between bacterial and fungal microbiota was analyzed based on Spearman correlation. Results Gut fungal diversity and community composition exhibited significant shifts in SLE compared with UCTDs, RA and HCs. Compared with HCs, the alpha and beta diversities of fungal microbiota decreased in SLE patients. According to principal coordinates analysis results, the constitution of fungal microbiota from SLE, RA, UCTDs patients and HCs exhibited distinct differences with a clear separation between fungal microbiota. There was dysbiosis in the compositions of fungal and bacterial microbiota in the SLE patients, compared to HCs. Pezizales, Cantharellales and Pseudaleuria were enriched in SLE compared with HCs, RA and UCTDs. There was a complex relationship network between bacterial and fungal microbiota, especially Candida which was related to a variety of bacteria. Conclusion This study presents a pilot analysis of fungal microbiota with diversity and composition in SLE, and identifies several gut fungi with different abundance patterns taxa among SLE, RA, UCTDs and HCs. Furthermore, the gut bacterial-fungal association network in SLE patients was altered compared with HCs.

Abstract
Fungal infections are estimated to be the main cause of death for more than 1.5 million people worldwide annually. However, fungal pathogenicity has been largely neglected. This is notably the case for pulmonary fungal infections, which are difficult to diagnose and to treat. We are currently facing a global emergence of antifungal resistance, which decreases the chances of survival for affected patients. New therapeutic approaches are therefore needed to face these life-threatening fungal infections. In this review, we will provide a general overview on respiratory fungal infections, with a focus on fungi of the genus Aspergillus. Next, the immunological and microbiological mechanisms of fungal pathogenesis will be discussed. The role of the respiratory mycobiota and its interactions with the bacterial microbiota on lung fungal infections will be presented from an ecological perspective. Finally, we will focus on existing and future innovative approaches for the treatment of respiratory fungal infections.

Abstract
This review lists current evidences for a contribution of gut mycobiota to the pathogenesis of SpA and related conditions. Gut mycobiota has a small size as compared to bacterial microbiota, but an even greater inter- and intra-individual variability. Although most fungi (brought by food or air) are only transitory present, a core mycobiota of gut resident fungi exists, and interplays with bacteria in a complex manner. A dysbiosis of this gut mycobiota has been observed in Crohn's disease and sclerosing cholangitis, with decreased proportion of Saccharomyces cerevisiae and outgrowth of more pathogenic gut fungi. Fungal-induced lower number of commensal gut bacteria can promote translocation of some bacterial/fungal antigens through mucosae, and live fungi can also cross the epithelial border in Crohn's disease. This dysbiosis also lower the ability of bacteria to metabolize tryptophan into regulatory metabolites, consequently enhancing tryptophan metabolism within human cells, which might contribute to fatigue. Translocation of mycobiotal antigens like curdlan (beta-glucan), which plays a major role in the pathogenesis of SpA in the SGK mice, has been observed in humans. This translocation of fungal antigens in human SpA might account for the anti-Saccharomyces antibodies found in this setting. Contribution of fungal antigens to psoriasis and hidradenitis suppurativa would fit with the preferential homing of fungi in the skin area most involved in those conditions. Fungal antigens also possess autoimmune uveitis-promoting function. As genes associated with SpA (CARD9 and IL23R) strongly regulate the innate immune response against fungi, further studies on fungi contribution to SpA are needed.
