Impact of Brief Exposure to Lysozyme and Lactoferrin on Pathogenic Attributes of Oral Candida.
Article in International dental journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
INTRODUCTION AND
aimsAdhesion to buccal epithelial cells (BEC) and denture acrylic surfaces (DAS), germ tube (GT) formation, cell surface hydrophobicity (CSH), and haemolysin production are attributes associated with pathogenicity of Candida. Candida albicans and Candida dubliniensis are allied in causing oral candidosis. Lysozyme and lactoferrin exert antimicrobial activity on a range of oral microorganisms, including Candida. There is no information on the impact of brief exposure to lysozyme and lactoferrin on adhesion-related attributes and haemolysin production of aforementioned oral Candida isolates. Thus, we investigated the impact of lysozyme and lactoferrin on adhesion to BEC and DAS, GT formation, CSH, and haemolysin production of these isolates.
methodsAfter exposure to lysozyme and lactoferrin for 1 hour, susceptibility to lysozyme and lactoferrin of 20 isolates each of C albicans and C dubliniensis isolates was determined following a 48-hour period of incubation. Candida cell suspensions, obtained from colony-forming units after this period, were assessed for adhesion to BEC and DAS, GT formation, CSH, and haemolysin production using in vitro assays.
resultsExposure to lysozyme and lactoferrin significantly suppressed the ability of C albicans and C dubliniensis isolates to adhere to BEC and DAS, GT formation, CSH, and haemolysin production (P < 0.01 for all virulent attributes tested).
conclusionsThese data provide a tantalising glimpse into the possibility that exposure to either lysozyme or lactoferrin, even for a brief period, would induce a sustainable antifungal effect by suppressing adhesion-related attributes and haemolysin production of these oral Candida species in vitro. Resistance to conventional antifungal agents has been reported in clinical isolates of Candida. The presence of such resistance indicates the need for possible alternative therapies to facilitate the management of oral candidosis. Further research on the pharmacodynamics of lysozyme and lactoferrin and their effects on candidal pathogenic attributes should be fostered, with the vision of developing novel topical antifungal drugs.
