Container Tracking and Security using RFID
In today's time, handling of a container is a time- consuming process. When they are unloaded from the ships or the trucks, the personal at the respective container yard have to go the respective container yard have to go to the container to check the container's identification number. Going through each and every container takes time. Also due to such a time- consuming process, sometimes the containers are let go even without checking them. This gives sometimes rise to smuggling of the goods. Also due to the presence of the manual work, there is always a danger of human error to occur. It proves to be costly to employ a huge manpower in container checking. Our project suggests a way of using RFID tag-reader system for container authorization and checking and GPS for tracking the container. The GPS along with the GSM module can be used by the industry to which the container belongs to continuously track it by getting the location coordinates on the mobile phones. This will make sure that the containers cannot be smuggled on their way to the destination
Subcutaneous Phaeohyphomycosis Caused by Phaeoacremonium Species in a Kidney Transplant Patient: The First Case in Korea
Phaeohyphomycosis is a subcutaneous infection caused by dark pigmented fungi, including fungi of the species Phaeoacremonium, Alternaria, Exophiala, and Pyrenochaeta. In August 2005, a 54-yr-old man who had received a renal transplant 5 yr ago was admitted to our hospital with a subcutaneous mass on the third finger of the right hand; the mass had been present for several months. He had been receiving immunosuppressive agents for several years. He underwent excision of the mass, which was followed by aspiration of the wound for bacterial and fungal cultures. Many fungal hyphae were observed on the histology slide treated with periodic acid-Schiff stain. A few white waxy colonies with a woolly texture grew on the Sabouraud dextrose agar at 30℃ and changed to dark brown in color. Nucleotide sequencing of internal transcribed spacer regions revealed 100% homology to the Phaeoacremonium aleophilum anamorph and Togninia minima teleomorph (514 bp/514 bp). The patient completely recovered after wide surgical excision. Here, we report the first case of phaeohyphomycosis caused by Phaeoacremonium species in a kidney transplant patient in Korea
Candida dubliniensis: An Appraisal of Its Clinical Significance as a Bloodstream Pathogen
A nine-year prospective study (2002–2010) on the prevalence of Candida dubliniensis among Candida bloodstream isolates is presented. The germ tube positive isolates were provisionally identified as C. dubliniensis by presence of fringed and rough colonies on sunflower seed agar. Subsequently, their identity was confirmed by Vitek2 Yeast identification system and/or by amplification and sequencing of the ITS region of rDNA. In all, 368 isolates were identified as C. dubliniensis; 67.1% came from respiratory specimens, 11.7% from oral swabs, 9.2% from urine, 3.8% from blood, 2.7% from vaginal swabs and 5.4% from other sources. All C. dubliniensis isolates tested by Etest were susceptible to voriconazole and amphotericin B. Resistance to fluconazole (≥8 µg/ml) was observed in 2.5% of C. dubliniensis isolates, 7 of which occurred between 2008–2010. Of note was the diagnosis of C. dubliniensis candidemia in 14 patients, 11 of them occurring between 2008–2010. None of the bloodstream isolate was resistant to fluconazole, while a solitary isolate showed increased MIC to 5-flucytosine (>32 µg/ml) and belonged to genotype 4. A review of literature since 1999 revealed 28 additional cases of C. dubliniensis candidemia, and 167 isolates identified from blood cultures since 1982. In conclusion, this study highlights a greater role of C. dubliniensis in bloodstream infections than hitherto recognized
COMPARISON BETWEEN FOUR USUAL METHODS OF IDENTIFICATION OF Candida SPECIES
SUMMARY Infection by Candidaspp. is associated with high mortality rates, especially when treatment is not appropriate and/or not immediate. Therefore, it is necessary to correctly identify the genus and species of Candida. The aim of this study was to compare the identification of 89 samples of Candida spp. by the manual methods germ tube test, auxanogram and chromogenic medium in relation to the ID 32C automated method. The concordances between the methods in ascending order, measured by the Kappa index were: ID 32C with CHROMagar Candida(κ = 0.38), ID 32C with auxanogram (κ = 0.59) and ID 32C with germ tube (κ = 0.9). One of the species identified in this study was C. tropicalis,which demonstrated a sensitivity of 46.2%, a specificity of 95.2%, PPV of 80%, NPV of 81.1%, and an accuracy of 80.9% in tests performed with CHROMagar Candida;and a sensitivity of 76.9%, a specificity of 96.8%, PPV of 90.9%, NPV of 91%, and an accuracy of 91% in the auxanogram tests. Therefore, it is necessary to know the advantages and limitations of methods to choose the best combination between them for a fast and correct identification of Candidaspecies
Notes for genera: basal clades of Fungi (including Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota)
Compared to the higher fungi (Dikarya), taxonomic and evolutionary studies on the basal clades of fungi are fewer in number. Thus, the generic boundaries and higher ranks in the basal clades of fungi are poorly known. Recent DNA based taxonomic studies have provided reliable and accurate information. It is therefore necessary to compile all available information since basal clades genera lack updated checklists or outlines. Recently, Tedersoo et al. (MycoKeys 13:1--20, 2016) accepted Aphelidiomycota and Rozellomycota in Fungal clade. Thus, we regard both these phyla as members in Kingdom Fungi. We accept 16 phyla in basal clades viz. Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota. Thus, 611 genera in 153 families, 43 orders and 18 classes are provided with details of classification, synonyms, life modes, distribution, recent literature and genomic data. Moreover, Catenariaceae Couch is proposed to be conserved, Cladochytriales Mozl.-Standr. is emended and the family Nephridiophagaceae is introduced

Species identification of <i>Candida</i> isolates obtained from oral lesions of HIV infected patients
A total of 60 patients suspected to have AIDS with oral lesions suggestive of oral candidiasis were studied. <i>Candida species </i>were isolated from 50 patients. <i>Candida albicans </i>was the commonest isolate (70 %) followed <i>Candida parapsilosis </i>(15%), <i>Candida glabrata </i>(7.5%) and <i>Candida tropicalis </i>(5%) respectively.<i> Candida dubliniensis</i> was isolated from a single case only. Though the reports from developed countries show more prevalence of the novel species <i>Candida dubliniensis</i>, in our study it was isolated in a single case. All the patients were treated successfully with oral fluconazole for 7 days except for the patients from which <i>Candida glabrata </i>was isolated, who were treated with Amphotericin B
Cutaneous zygomycosis due to <i>Saksenaea vasiformis</i> in an immunocompetent host
Saksenaea vasiformis is an emerging zygomycete species, most often associated with cutaneous, subcutaneous and rhino- orbito-cerebral infections. Herein, we report a case of cutaneous zygomycosis of face caused by Saksenaea vasiformis in a 54-year-old immunocompetent female. The diagnosis was carried out by microscopy using KOH mount, Gram staining, Gomori′s methenamine silver staining, hemotoxylin and eosin staining and culture on Sabouraud′s Dextrose agar without actidione. Slide cultures were put up on Czapek Dox agar, which showed typical flask-shaped sporangium with rhizoids. The patient was treated successfully with intravenous amphotericin B
