摘要

假丝酵母菌和金黄色葡萄球菌在医院感染中共存。这些领域间的相互作用与口腔生物膜的形成有关,导致各种口腔疾病。本研究阐明了这些微生物在三种不同介质中的相互作用,特别是它们的聚集和生物膜的形成。研究对象为耳念珠菌、白色念珠菌、卢西塔念珠菌、巴黎念珠菌、准假丝酵母菌、光秃念珠菌和金黄色葡萄球菌。通过聚集实验来确定浮游生物的相互作用,通过生物膜实验来研究静态生物膜环境中生物群落内部和群落间的相互作用。大多数念珠菌在添加酵母提取物(BHIYE)的脑心灌注液中表现出较高的自聚集率。此外,与单一培养相比,与金黄色葡萄球菌共培养的生物膜显著减少念珠菌的总细胞计数(p . S.)。金黄色葡萄球菌与念珠菌有拮抗作用。

Aggregation and biofilm formation of mono- and co-culture Candida species and Staphylococcus aureus are affected by nutrients in growth media.

Candida species and Staphylococcus aureus coexist in nosocomial infections. These interkingdom interactions are associated with oral biofilm formation, leading to various oral diseases. This study elucidated the interkingdom interactions of these microorganisms, particularly their aggregation and biofilm formation, in three different media. Candida auris, Candida albicans, Candida lusitaniae, Candida dubliniensis, Candida parapsilosis, Candida glabrata and S. aureus were used in this study. Aggregation assays were conducted to determine planktonic interaction, and biofilm assays were performed to investigate intra- and interkingdom interactions in a static biofilm environment. Most Candida spp. exhibited a high auto-aggregation percentage in brain heart infusion broth supplemented with yeast extract (BHIYE). In addition, co-culture biofilm with S. aureus significantly reduced the total cell counts of Candida spp. compared to mono-culture (p < 0.05). In conclusion, co-aggregation, biofilm biomass and total cell count were species- and growth medium-dependent, and S. aureus interacted antagonistically with Candida spp.

期刊介绍: Biofouling is an international, peer-reviewed, multi-discliplinary journal which publishes original articles and mini-reviews and provides a forum for publication of pure and applied work on protein, microbial, fungal, plant and animal fouling and its control, as well as studies of all kinds on biofilms and bioadhesion. Papers may be based on studies relating to characterisation, attachment, growth and control on any natural (living) or man-made surface in the freshwater, marine or aerial environments, including fouling, biofilms and bioadhesion in the medical, dental, and industrial context. Specific areas of interest include antifouling technologies and coatings including transmission of invasive species, antimicrobial agents, biological interfaces, biomaterials, microbiologically influenced corrosion, membrane biofouling, food industry biofilms, biofilm based diseases and indwelling biomedical devices as substrata for fouling and biofilm growth, including papers based on clinically-relevant work using models that mimic the realistic environment in which they are intended to be used.
