Abstract The viability of pathogenic fungi in the scale was investigated during topical administration of 1% luliconazole (LLCZ). Thirteen tinea pedis patients found to be positive on KOH examination were assessed by mycological examinations and quantitative real-time polymerase chain reaction (PCR) targeted internal transcribed spacer (ITS) in ribosomal RNA gene at the initial visit and after 2 and 4 weeks of treatment. Assays showed that the average copy number of ITS DNA had significantly decreased to 22.9% at 2 weeks and 4.8% at 4 weeks compared with the initial visit. LLCZ topical treatment could defeat almost pathogenic dermatophytes in the scales within 4 weeks.

The acetic acid bacterium <em>Asaia</em> spp. was successfully detected in <em>Anopheles arabiensis</em> Patton, 1905, one of the major vector of human malaria in Sub-Saharan Africa. A collection of 45 <em>Asaia</em> isolates in cellfree media was established from 20 individuals collected from the field in Burkina Faso. 16S rRNA universal polymerase chain reaction (PCR) and specific qPCR, for the detection of <em>Asaia</em> spp. were performed in order to reveal the presence of different bacterial taxa associated with this insect. The isolates were typed by internal transcribed spacer-PCR, BOX-PCR, and randomly amplified polymorphic DNA-PCR, proved the presence of different <em>Asaia</em> in <em>A. arabiensis</em>.

Abstract Objective The mechanisms underlying the onset and progression of peri-implantitis are similar to those of periodontitis, and the causative bacteria are believed to similar. Previous studies support an association between peri-implantitis and periodontal pathogen. Thus, we investigated the bacterial flora of peri-implantitis patients in comparison to those of healthy implant and periodontitis patients. Materials and methods In total, 70 patients visiting Tokyo Dental College Chiba Hospital were divided into four groups: healthy, periodontitis, healthy implant, and peri-implantitis. For each group, the following five periodontal pathogens were detected using real-time polymerase chain reaction: Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Treponema denticola, and Prevotella intermedia. Results The average copy number of total bacteria was significantly higher in the periodontitis group than in the other groups. P. gingivalis was detected in the periodontitis and peri-implantitis groups at levels as high as 18.92% and 12.29%, respectively, and P. intermedia was found in the peri-implantitis group at a rate of 2.06%. Nevertheless, periodontal pathogens were generally detected at lower levels in the peri-implantitis group than in the periodontitis group. Conclusion We found lower bacterial counts in the peri-implantitis group relative to the periodontitis group. Our results suggest that the peri-implant tissue is less resistant to bacteria, so even a small number of bacteria can be a risk factor for peri-implantitis and the causative agent of peri-implantitis can be bacteria other than periodontal pathogen.

A DNA microarray test based on internal transcribed spacer 1 (ITS1) genotype expression was developed to identify Culicoides species of Northwestern Europe belonging to the Culicoides Obsoletus complex. The assay was designed so as to allow interpretation by the naked eye. False positive and false nega­tive results were eliminated. The need for expensive laboratory equipment and reagents was kept as low as possible, making the technique affordable and feasible for any diagnostic laboratory with polymerase chain reaction (PCR) facilities. The microarray test could be validated through the three ringtests organised by Medreonet. Use of this microarray can improve monitoring adult and immature Culicoides species.

Aim: The Mitochondrial transcription factor A (TFAM) and mitochondrial (mt) DNA copy number variations are known to contribute in disease development. Genetic factors play an important role in the development of endometriosis. Therefore, this case–control study aimed to analyze the association of TFAM+35G/C polymorphism and mitochondrial copy number with the risk of endometriosis in Indian women. Study Design: This study was carried out on 418 subjects including 200 endometriosis cases and 218 controls. Methodology: Genotyping of TFAM +35G/C polymorphism (rs1937) was carried out by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Quantification of mtDNA copy number was carried out using a real time quantitative polymerase chain reaction (qRT-PCR). Place and Duration of Study: Department of Biochemistry, Osmania University, 2014 to 2020. Results: TFAM genotype as well as allele distributions were all in Hardy-Weinberg equilibrium. The results indicated a significant reduction of GG genotype frequency (P=0.009), high ‘C’ allele frequency (P=0.017) and significantly decreased mtDNA copy number in endometriosis cases compared to controls (P= 0.0001). Conclusion: Present study revealed a statistically significant association of decreased GG genotype of TFAM +35G/C polymorphism and mtDNA copy number with the risk of developing endometriosis in Indian women.
