Accurate and rapid diagnosis of dermatophytosis, a disease whose prevalence has been steadily increased, is important for successful treatment. Current laboratory methods for diagnosing dermatophytosis rely on KOH mount and fungal culture method. However, these methods have low sensitivity and are time-consuming (2~4 weeks to diagnosis). In our previous study, a rapid molecular diagnostic assay (PCR-reverse blot hybridization assay, REBA) was developed to identify the following 6 main species of dermatophytes: Trichophyton rubrum, T. mentagrophytes, T. tonsurans, Microsporum canis, M. gypseum, and Epidermophyton floccosum. However, the REBA required more evaluation to validate its use in clinical examinations. The aim of the present study was to evaluate and validate the ability of the PCR-REBA to successfully identify dermatophytes in clinical isolates from dermatophytosis patients. Both conventional identification methods and the PCR-REBA were used to assess the presence of species of dermatophytes in 148 clinical isolates. The results of the two approaches were compared, and discrepancies between the two approaches were resolved by fungal ITS1 sequence analysis. T. rubrum was the most prevalent dermatophyte identified by conventional identification methods (118/148, 79.7%) and the PCR-REBA (131/148, 88.4%). The overall rate of consistency between conventional identification methods and the PCR-REBA was 79.0% (117/148 samples). Fungal ITS1 sequence analysis showed that PCR-REBA results were correct for 93.5% (29/31) of the discrepant samples. The PCR-REBA is rapid, sensitive, and highly specific compared with conventional identification methods. Thus, the PCR-REBA is a potentially useful tool for identifying dermatophytes in clinical settings.

The marine dinoflagellate genus Alexandrium comprise PSP producing A. acatenella, A. angustitabuzatum, A. catenella, A. fundyense, A. minutum, A. ostenfezdii, A. tamiyavanichii and A. tamarense. In monitoring toxic Alexandrium, rapid and exact species identification is one of the significant prerequisite work, however we have suffered confusion of species definition in Alexandrium. To surmount this problem, we chose DNA probing, which has long been used as an alternative for conventional identification methods, primarily relying on morphological approaches using microscope in microbial field. Oligonucleotide DNA probes targeting rRNA or rDNA have been commonly used in diverse studies to detect and enumerate cells concerned as a culture-indetendent powerful tool. Despite of the massive literature on the HAB species containing Alexandrium, application of DNA probing for species identification and detection has been limited to a few documents. DNA probes of toxic A. tamarense, A. catenella and A. tamiyavanichii, and non-toxic A. affine, A. fraterculus, A. insuetum and A. pseudogonyaulax were designed from LSU rDNA D1-D2, and applied to whole cell-FISH. Each DNA probes reacted only the targeted Alexandrium cells with very high species-specificity within Alexandrium. The probes could detect each targeted cells obtained from the natural sea water samples without cross-reactivity. Labeling intensity varied in the growth stage, this showed that the contents of probe-targeted cellular rRNA decreased with reduced growth rate. Double probe TAMID2S1 achieved approximately two times higher fluorescent intensity than that with single probe TAMID2. This double probe did not cross-react with any kinds of microorganisms in the natural sea waters. Therefore we can say that in whole-cell FISH procedure this double DNA probe successfully labeled targeted A. tamiyavanichii without cross-reaction with congeners and diverse natural bio-communities.

Members of the genus Acinetobacter are recognized as newer pathogens of the nosocomial infection with an increasing frequency in recent years. Strains that belonged to A. calcoaceticus A. baumannii complex (genomic species 1, 2, 3, and 13TU) were major groups associated with nosocomial infection. Phenotypic identification was unreliable and laborious method to classify Acinetobacter strains into 19 genomic species. Rapid and reliable identification of clinical isolates is essential to diagnosis and epidemiology of Acinetobacter. We investigated the suitability of amplified ribosomal DNA restriction analysis (ARDRA) to identify genomic species of 131 Acinetobacter isolates. The 16S rRNA genes (ribosomal DNA) were enzymatically amplified and the amplified PCR products were restricted independently with the enzymes, AluI, CfoI, and MboI. Genomic species of Acinetobacter was classified by the combinations of restriction patterns. The analysis was showed that restriction profiles were characteristic for each genomic species. One hundred fourteen isolates were identified as A. baumannii, twelve were identified as genomic species 13TU, and one was identified as genomic species 3. Four isolates were found to be unknown organisms. All of the isolates which were identified to A. baumannii by phenotypic tests were completely discriminated into A. baumannii and genomic species 13TU by ARDRA. This study demonstrates that ARDRA is a rapid and simple techniques for the identification of Acinetobacter species according to the genomic species.

Commercial one-step rapid fecal occult blood (FOB) kit which was used as a screening test to detect traces of blood in stool samples was evaluated for the feasibility of the forensic identification of human blood. The sensitivity was determined and compared with the conventional Leucomalichite green (LMG) method. In addition, the specificity of the kit and the effects of various chemicals and environmental factors were examined. FOB kit was specific for human hemoglobin and more sensitive than LMG test (approximately 100 times). FOB kit showed positive band using at least 1,000,000-fold diluted human blood. The antigen was very stable regardless of storage temperature and boiling. The positive reaction was not affected by LMG and Luminol, the traditional tests for identification of bloodstain. As a results, FOB test kit could be effectively applied to identification of human blood at crime scene and crime laboratories.

The glucose nonfermenting gram-negative bacilli encountered about 10% of all gram-negative bacilli isolated from clinical material. Therefore, a rapid and correct identification of glucose nonfermenting gram-negative bacilli is impostent for a better management of infectious disease. There are many conventional systems for the Identification of glucose nonfermenting gram-negative bacilli but most of them have problems and difficulties. Commercial Kit Systems exist and they are too expensive for dally use 10 Korea because of high cost. Based on 12 selected tests we propose a new code system, MCRCODE-N for rapid and 10-expensive identification of glucose nonfermenting gram-negative bacilli. The selective 12 tests are oxidase, glucose oxidation motility, urease, DNase arginine dehydrolase, nitrate reduction, gelatin Liquefaction, esculin hydrolysis, mannitol oxidation, maltose oxidation, Lactose oxidation. The 12 tests are divided 4 group and then each group has 3 tests. The result of each group is expressed by the number as below. The positive test is given by specific number (1st test = 1, 2nd test = 2, 3rd test = 4), while any negative result is 0. Each 3 numbers of one group are added and make number of 1 digit. Four digit number is refered to the code book of MCRCODE-N system or MCRCODE system using computer (Apple-II model) created by authors. This MCRCODE-N system is suitable ones for our use 10 Korea. We propose the MCRCODEN-N system for clinical use.

Recent years have seen an increase in the incidence of candidiasis caused by non-albicans Candida (NAC) species. In fact, C. glabrata is now second only to C. albicans as the most common cause of invasive candidiasis. Therefore, the rapid genotyping specifically for C. glabrata is required for early diagnosis and treatment of candidiasis. A number of genotyping assays have been developed to differentiate C. glabrata sequence types (STs), but they have several limitations. In the previous study, multi-locus sequence typing (MLST) has performed with a total of 101 C. glabrata clinical isolates to analyze the prevalent C. glabrata STs in Korea. A total of 11 different C. glabrata STs were identified and, among them, ST-138 was the most commonly classified. Thus, a novel probe-based quantitative PCR (qPCR) assay was developed and evaluated for rapid and accurate identification of the predominant C. glabrata ST-138 in Korea. Two primer pairs and hybridization probe sets were designed for the amplification of internal transcribed spacer 1 (ITS1) region and TRP1 gene. Analytical sensitivity of the probe-based qPCR assay was 100 ng to 10 pg and 100 ng to 100 pg (per 1 μL), which target ITS1 region and TRP1 gene, respectively. This assay did not react with any other Candida species and bacteria except C. glabrata. Of the 101 clinical isolates, 99 cases (98%) were concordant with MLST results. This novel probe-based qPCR assay proved to be rapid, sensitive, highly specific, reproducible, and cost-effective than other genotyping assay for C. glabrata ST-138 identification.
