A total of 135 stomach samples from patients with gastrointestinal diseases and normal controls were examined for Helicobacter pylori infection and Candida colonization. Candida krusei was found in specimens from 20% bleeding, 52% ulcer, and 100% gastritis patients, whereas H. pylori infection rates were 82%, 35% and 30%, respectively, for the same groups of patients. C. krusei was not detected...
BACKGROUND To assess the performance of Candida albicans germ tube antibody (CAGTA), (1 → 3)-ß-D-glucan (BDG), mannan antigen (mannan-Ag), anti-mannan antibodies (mannan-Ab), and Candida DNA for diagnosing invasive candidiasis (IC) in ICU patients with severe abdominal conditions (SAC). METHODS A prospective study of 233 non-neutropenic patients with SAC on ICU admission and expected stay ≥ 7...
Colonization with Candida species is an independent risk factor for invasive candidiasis (IC), but the minimum and most practicable parameters for prediction of IC have not been optimized. We evaluated Candida colonization in a prospective cohort of 6,015 nonneutropenic, critically ill patients. Throat, perineum, and urine were sampled 72 h post-intensive care unit (ICU) admission and twice wee...
The incidence of candidemia--a common and potentially fatal nosocomial infection--has risen dramatically, and this increase has been accompanied by a shift in the infecting pathogen away from Candida albicans to treatment-resistant non-albicans species. Prophylactic azole antifungals, such as fluconazole, may play an important role not only in the management of candidemia but also in the prolif...
Precipitins to mannan and cytoplasmic antigens of Candida albicans and Torulopsis glabrata were determined in 25 patients with colonization of the bladder urine by yeasts and in 25 control patients with bacteriuria. Precipitins were present in 64% of the patients with funguria and in 56% of the patients with bacteriuria. There was no correlation between the reactions obtained and the clinical s...
In vitro coaggregation between Candida species isolated from immunosuppressed bone marrow transplant recipients and oral bacteria was investigated. Each Candida strain showed a different pattern of coaggregation with the 22 bacterial strains studied. Two strains of Lactobacillus amylovorus isolated from separate bone marrow transplant patients and Fusobacterium nucleatum (VPI 10197) coaggregate...
Severe infections due to Candida species have become more frequent during the past two decades because of the increasing numbers of immunosuppressed patients being treated in our hospitals. Distinguishing colonization from invasive disease requires knowledge of the pathogenetic mechanisms leading to invasion. To assist the clinician in therapeutic decisions, clinical microbiologists should iden...
Fungi are major causes of infections among immunocompromised or hospitalized patients with serious underlying diseases and comorbidities. Candida species remain the most important cause of opportunistic infections worldwide, affecting predominantly patients over 65 years old, while they are considered to be the fourth most common cause of nosocomial bloodstream infections. The rapidly growing e...
Background: Fungi are oral commensal in about half of general population and its largest proportion is made up of Candida species. Candida causes wide variety of infections in human beings. Objectives: To evaluate the prevalence of Candida species in root canals and oral cavities of children and adults. Material and methods: Swabs from oral cavities of 100 patients were collected and subjected ...
BACKGROUND Patients undergoing radiation therapy for oral squamous cell carcinoma (OSCC) have an increased risk of developing oral candidiasis. Radiation-induced hyposalivation is thought to be a major predisposing factor for it. Radiation therapy for 2-3 weeks leads to increase in the number of candidal species in the oral cavity, eventually leading to oral candidiasis. OBJECTIVE To evaluate...
