| Abstract | PURPOSE: A definitive diagnosis of invasive oral aspergillosis can be difficult because the culturing of tissue samples frequently fails to isolate Aspergillus species. In addition, the mycelial elements of Aspergillus species seen in tissue sections are histopathologically indistinguishable from those of non-Aspergillus species. We analyzed the usefulness of a DNA probe directed against the alkaline proteinase (ALP) gene of Aspergillus fumigatus for the identification of Aspergillus species by the in situ hybridization (ISH) technique in patients with oral mycosis. PATIENTS AND METHODS: The ALP probe was tested on tissue specimens from 16 patients with hematologic malignancies who had invasive, orofacial fungal infections and a positive culture for one of the following organisms: Aspergillus species in 13 patients (A. flavus in 10, A. terreus in 2, and A. fumigatus in 1), and Exophiala dermatitis, Trichoderma longibrachiatum, and Candida albicans in 1 patient each. In situ hybridization with the ALP probe was performed using formalin-fixed, paraffin-embedded tissue samples. RESULTS: The ALP probe showed a strong reaction with specimens from all 13 patients who had culture-proven aspergillosis specimens attributable to A. flavus, A. terreus, and A. fumigatus. On the other hand, the ALP probe showed no cross-reactivity with other fungi (Exophiala dermatitis, Trichoderma longibrachiatum, and Candida albicans). CONCLUSION: These findings indicate that ISH using an ALP probe may increase the accuracy of diagnosing invasive oral aspergillosis in immunocompromised patients, and facilitate the provision of adequate antifungal treatment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
