introduction: oral candidosis is among the find-ings of acute leukemia. the aim of this study was to evaluate the changes in the intensity of c.albicans, before treatment and at the induc-tion phase. materials and methods: twelve patients with acute lymphoblastic leukemia (all) aged 2-14 years enrolled in study. whole saliva samples were obtained and cultured to determine the mean count of c.al...

The steady-state growth of a Flavobacterium strain known to utilize pentachlorophenol (PCP) was examined when cellobiose and PCP simultaneously limited its growth rate in continuous culture. A concentration of 600 mg of PCP per liter in influent medium could be continuously degraded without affecting steady-state growth. We measured specific rates of PCP carbon degradation as high as 0.15 +/- 0...

Introduction: Mobile phones and computers are a reservoir of growth and transmission of microorganisms. This study aimed to evaluate the microbial contamination of computers and mobile phones used by students of an academic dental school, compared to the students of a non-medical school. Methods: Sampling was performed on 44 computers and 45 mobile phones in a dental school (test) and a non-med...

A method of adaptive control military radio network parameters has been developed. This allows predicting suppressed frequencies by electronic warfare devices, determining the topology network. Also, this rational routes information transmission and operating mode communications. Forecasting environment is characterized recirculation input data for one count, resampling on a logarithmic time sc...

statement of the problem: candida species are believed to play an important role in initiation and progression of denture stomatitis. the type of the denture material also influences the adhesion of candida and development of stomatitis. purpose: the aim of this study was comparing the adherence of candida albicans to the conventional and injection molding acrylic denture base materials. materi...

patients afflicted by diabetes mellitus (dm) usually have more infections than those without dm. the course of the infections is also more complicated in this group of patients. one of the possible causes of increased infections prevalence is a deficiency in the immunity. besides some decreased cellular responses in vitro, no disturbances in adaptive immunity in diabetic patients have been desc...

Neonicotinoid insecticides can cause a variety of adverse sub-lethal effects in bees. In social species such as the honeybee, Apis mellifera, queens are essential for reproduction and colony functioning. Therefore, any negative effect of these agricultural chemicals on the mating success of queens may have serious consequences for the fitness of the entire colony. Queens were exposed to the com...

We developed a rapid and efficient method based on culture on selective medium and colony hybridization assay for the detection of Vibrio cholerae in estuarine water samples. A 22-oligonucleotide sequence of the 16S-23S rDNA intergenic spacer region was labeled with digoxigenin and evaluated for specificity and sensitivity by dot blot and colony hybridization with collection strains and environ...
