biotypes of oral candida albicans isolates in human immunodeficiency virus-infected patients from diverse geographic locations.oral candida albicans isolates from hiv-infected individuals in hong kong, australia, germany and england were characterised using a biotyping system based on enzyme profiles, carbohydrate assimilation patterns and boric acid resistance of the yeasts. a total of 44 biotypes were found amongst the 117 oral c. albicans isolates examined. the major biotype a1r accounted for 17.9% of all isolates while the second commonest biotype was a1s (11.1% of isolates). whereas these two biotypes were isolated ...19957722918
the oral prevalence of aerobic and facultatively anaerobic gram-negative rods and yeasts in hong kong chinese.saline oral rinse samples were obtained from 300 community-dwelling hong kong chinese attending an outpatient dental clinic to determine the oral prevalence of aerobic and facultatively anaerobic gram-negative rods (agnr) and yeasts. the oral prevalence of agnr was 41.7%. enterobacteriaceae species comprised 73% of all agnr isolated, with an overall prevalence of 32%. there was no difference in prevalence between females (n = 190) and males (n = 110). morning samples (n = 154) yielded a signific ...19948067914
onychomycosis in hong kong.onychomycosis in temperate countries has been studied extensively, but few data are available on its epidemiology in tropical countries. we performed a survey of patients seen in hong kong for the 8-year period from january 1987 to december 1994.19979372350

oral colonization, phenotypic, and genotypic profiles of candida species in irradiated, dentate, xerostomic nasopharyngeal carcinoma survivors.the aim of this study was to investigate oral yeast colonization and oral yeast strain diversity in irradiated (head and neck), dentate, xerostomic individuals. subjects were recruited from a nasopharyngeal carcinoma clinic and were segregated into group a (age, <60 years [n = 25; average age +/- standard deviation (sd), 48 +/- 6 years; average postirradiation time +/- sd, 5 +/- 5 years]) and group b (age, >/=60 years [n = 8; average age +/- sd, 67 +/- 4 years; average postirradiation time +/- s ...200010834980
oral yeasts and coliforms in hiv-infected individuals in hong kong.the objective was to determine the oral carriage patterns of yeasts and coliforms and their relationships, if any, with age, risk group, cdc classification, cd4+ count and medications in a predominantly chinese, hiv-infected cohort in hong kong. a prospective longitudinal study was carried out over a 12-month period, of 32 predominantly chinese male hiv-infected cohort in a hospital setting in hong kong. oral carriage rates were determined by the concentrated rinse culture method and correlated ...200011036401
bacterial and yeast flora of root surface caries in elderly, ethnic chinese.root caries is emerging as a significant problem in the middle aged and elderly. as little data is available on the microbiology of root caries in chinese cohorts, we evaluated 30 such lesions in elderly, institutionalized, ethnic chinese.200212206402
'genotypic shuffling' of sequential clones of candida albicans in hiv-infected individuals with and without symptomatic oral candidiasis.although hiv-infected individuals harbour multiple strains of oral candida albicans, little is known of their micro-evolution over time. therefore, a prospective study was conducted with 16 hiv-infected ethnic chinese individuals with and without symptoms of oropharyngeal candidiasis to evaluate the genotype distribution of oral c. albicans isolates during hiv disease progression. oral-rinse samples were obtained from all individuals and up to five c. albicans colonies were selected for each vis ...200312676875
a 4-year longitudinal study of the oral prevalence of enteric gram-negative rods and yeasts in chinese children.a 4-year longitudinal study of the oral prevalence of enteric gram-negative rods and yeasts in 116 chinese primary school children in hong kong was conducted. the oral prevalence of enteric gram-negative rods for each consecutive year was 25.3%, 37.0%, 24.0% and 25.8% respectively, with a weighted mean of 27.9%. enterobacteriaceae, which comprised 57% of all enteric gram-negative rods, were more common in children with no caries experience. the oral prevalence of yeasts for each consecutive year ...19979467406
salivary lysozyme and related parameters of a predominantly chinese, hiv-infected cohort in hong evaluate the salivary lysozyme concentration, flow rate and ph of a predominantly chinese, hiv-infected group in hong kong, and to compare with an equal number of age and gender-matched hiv-free individuals.199910483071
