OBJECTIVES: Since time immemorial, plants have continued to play a predominant role in the maintenance of human health as sources of medicinal compounds. Several effective antifungal agents are available for oral Candida infections; the failure is not uncommon because isolates of Candida albicans may exhibit resistance to the drug during therapy. The present study aimed to identify an alternative, inexpensive, simple, and effective method of preventing and controlling the candidal infection...

CONTEXT: Most of the adult population is colonized by Candida in their oral cavity. The process of colonization depends on several factors, including the interaction between Candida and salivary proteins. Therefore, salivary gland hypofunction may alter the oral microbiota and increase the risk for opportunistic infections, such as candidiasis. Hence, it is necessary to evaluate the relationship between salivary flow rates (SFRs) and Candida colony counts in the saliva of patients with xerostomia...

The Göttingen minipig is often used in preclinical toxicity studies. Therefore, knowledge of spontaneously occurring pathologies is important to differentiate them from test drug-related effects. We report on a Göttingen minipig, which developed exudating widespread dermatitis during a preclinical toxicity study with a subcutaneously injected drug. The lesions were resistant to topical and oral antibacterial medications. Skin cultures were positive for Candida albicans, and treatment was changed to topical antifungal cream with quick resolution of the skin lesions...

PURPOSE: Since the first descriptions of medication-related osteonecrosis of the jaw (MRONJ) in 2003, the pathogenesis has remained unanswered. Recent histomorphometric studies have found several microorganisms, including Actinomyces, Bacillus, Fusobacterium, Staphylococcus, Streptococcus, Selenomonas, Treponema, and Candida albicans in necrotic bone. Polymerase chain reaction studies have recently confirmed the occurrence of 48 genera. Only a few studies have examined the antimicrobial effect of bisphosphonates (BPs)...

INTRODUCTION: Candida albicans being a part of the normal oral microbial flora is one of the most commonly isolated species from the oral cavity. Recent studies have shown a steady rise in the number of non C. albicans species, which are relatively resistant to common antifungal agents and are being recognized as potential pathogens. It is vital to ascertain the predisposing factors leading to such a shift in the oral candidal flora. AIM: To estimate the prevalence of candidal species among vegetarians and non-vegetarians...

Oral candidiasis or thrush is a fungal infection due to Candida albicans, causing discomfort in areas inside mouth or tongue. The clinical application of antifungal reagent amphotericin B (AMB), which is believed to offer a better treatment for oral candidiasis, is greatly compromised by its toxicities (mainly nephrotoxicity) and poor solubility. In order to overcome these issues, we characterized AMB-loaded MPEG-PCL micelles in vitro and in vivo. In addition, the antifungal activities of AMB/MPEG-PCL micelles-loaded buccal tablet were also evaluated in vitro...
