A proteomic-based approach for the identification ofCandida albicans protein components present in a subunit vaccine that protects against disseminat…
2006
Candidiasis has become a prevalent infection in different types of immunocompromised patients. The cell wall of Candida albicans plays important functions during the host-fungus interactions. Cell wall (surface) proteins of C. albicans are major elicitors of host immune responses during candidiasis, and represent candidates for vaccine development. Groups of mice were vaccinated subcutaneously with a beta-mercaptoethanol (beta-ME) extract from C. albicans containing cell wall proteins. Vaccinated mice were then infected with a lethal dose of C. albicans. Increased survival and decreased fungal burden were observed in vaccinated mice as compared to a control group, and 75% of vaccinated mice…
Expression of the fibrinogen binding mannoprotein and the laminin receptor of Candida albicans in vitro and in infected tissues.
1996
We have previously reported a 37 kDa laminin-binding protein (p37) and a 58 kDa fibrinogen-binding mannoprotein (mp58) on the surface of Candida albicans. A few yeast cells expressed both functional receptors at the surface while germ tubes expressed a functional mp58 fibrinogen but not a functional p37 laminin receptor. These receptors were heterogeneously dispersed at the surface as shown by binding of rabbit antiserum to mp58 (PAb anti-mp58) and antiserum to the human high affinity laminin receptor. In this report we have used a dual fluorescence technique to determine if the two receptors colocalize, perhaps as part of a receptor complex. Fibrinogen was used as a probe for mp58 and poly…
Retinal microglia are activated by systemic fungal infection
2014
Purpose: To determine whether systemic fungal infection could cause activation of retinal microglia and therefore could be potentially harmful for patients with retinal degenerative diseases. Methods: Activation of retinal microglia was measured in a model of sublethal invasive candidiasis in C57BL/6J mice by (i) confocal immunofluorescence and (ii) flow cytometry analysis, using anti-CD11b, anti-Iba1, anti-MHCII and anti-CD45 antibodies. Results: Systemic fungal infection causes activation of retinal microglia, with phenotypic changes in morphology, surface markers expression, and microglial re-location in retinal layers. Conclusions: As an excessive or prolonged microglial activation may …
Le tracce dell'esegesi paremiografica di Didimo nella tradizione scolastica
2016
This article aims to recognize the remains of Didymus’ scholarly activity related to exegesis on proverbs inside the scholiastic corpora of tragic and comic poets, which, as it happens in the Demosthenic commentary preserved in P.Berol. inv. 9780 (11, 52-12, 33), in some cases show a significant relationship with later paroemiographical sources. These evidences are examined in order to determine whether or not Didymus and Lucillus of Tarrhae might have transposed into their collections of proverbs the historical and mythographical material used by themselves to enrich commentaries and technical works.
Typhoid fever as a cause of opportunistic infection: case report.
2005
Abstract Background Typhoid fever is a systemic infection caused by the bacterium Salmonella enterica subspecies enterica serotype typhi, which is acquired by ingestion of contaminated food and water. Each year the disease affects at least 16 million persons world-wide, most of whom reside in the developing countries of Southeast Asia and Africa. In Italy the disease is uncommon with a greater number of cases in Southern regions than in Northern ones. Case presentation We report on a 57-year-old Sri-Lankan male affected by typhoid fever, the onset of which was accompanied by oropharyngeal candidiasis. This clinical sign was due to a transient cell-mediated immunity depression (CD4+ cell cou…
Carbohydrate assimilation profiles of the first Italian Candida dubliniensis clinical isolates recovered from an HIV-infected individual.
2001
A total of six Candida dubliniensis isolates were obtained during 1 year of monitoring by monthly swabs from the oral cavity of an asymptomatic human immunodeficiency virus-infected individual in Catania, Italy. To the authors' knowledge, this constitutes the first recovery of C. dubliniensis from a human in Italy. Our identification procedure was based on colony color on CHROMagar Candida and carbohydrate assimilation profiles obtained by two commercial systems: API ID 32C and API 20C AUX. Karyotyping by pulsed-field gel electrophoresis confirmed the phenotypic identification. The biocodes obtained with API 20C AUX and with API ID 32C were 6172134 and 7142140015, respectively, for all six …
Candida pararugosa isolation from the oral cavity of an Italian denture wearer
2004
Candida pararugosa was first isolated from human feces, but after the initial description no further recovery from humans has been reported. During a study on oral Candida colonization in denture wearers living in Palermo (Italy), we isolated C. pararugosa from a 61-year-old woman without signs of oral candidosis. This constitutes, to the authors' knowledge, the first isolation of C. pararugosa from the oral cavity. After six months, colonization by C. pararugosa persisted, suggesting that this species could be a component of the normal oral microbiota. The identification procedure we used could be useful in elucidating the epidemiology of C. pararugosa and for establishing its clinical sig…
Tonometers and infectious risk: myth or reality? Efficacy of different disinfection regimens on tonometer tips
2006
Purpose To evaluate the adequacy of common disinfection regimens for disposable tonometer tips and assess if disinfection of reusable prisms or the use of disposable tips is preferable. Methods We used disposable tonometer tips, using the same material and tip diameter of standard Goldmann tonometer prism. Strains of Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Candida albicans were tested according to the European standard guidelines for disinfectants test. Antimicrobial effectiveness of the following disinfection practices has been assessed: dry wipe, Minuten wipes (Alpros), soaking in 3% hydrogen peroxide, 0.5% benzalkonium chloride, and 0.5% Pantasepts for 1, 5, …
REPORT OF A CASE OF MALIGNANT TUMOR-LIKE GASTRIC LESION BY CANDIDA IN A DIABETIC TREATED WITH CYCLOSPORINE FOR PSORIASIS AND REVIEW OF THE LITERATURE
2011
Mycotic infection of the alimentary canal are rare and usually involve the upper digestive tract. Mycetes, especially of Candida family, are habitual saprophytes in the digestive tract of healthy individuals. Under certain conditions, fungal flora may overgrowth, resulting in lesions of the digestive mucosa, which, rarely, might evolve to local diffusion and/or systemic lympho-hematogenous spreading. In the stomach, sometimes, mycotic infections may appear like benign gastric ulcers. we described a case of woman, aged 64, affected by psoriasis, in chronic treatment with cyclosporine and type 2 diabetes mellitus, a well-known immunosoppressive condition, with endoscopic evidence of ulcerated…
