AbstractIdentification of species for the study of biodiversity in the phylum Nemata is defined as being able to identify any of the 12 000 described species of nematodes, and being able to recognise when the specimen under study belongs to a species unknown to science. Moreover, this large-scale identification must be done by biologists who are not expert taxonomists. It is argued that printed identification aids are too rigid and unreliable, and molecular identification aid is too limited, to be used in this context. Only computer identification tools are flexible, reliable, and general enough to give a non-taxonomist the possibility to identify any species. However, a review of existing tools and approaches shows that they fall short of reaching this objective. The functionality of a general identification system that could overcome the problems and difficulties encountered in the use of computerised tools is then described. This system (which has been described by the authors in several articles under the name of Genisys) would include a general database with all the characters from all the published descriptions of nematodes species and a set of integrated identification tools. Some of these tools would export the data into formats usable by existing identification and systematics tools. Other tools would have to be developed to support new approaches. A guidance tool would help the non-expert user by suggesting the successive computerised tools to be used during an identification session or by directing the user to other approaches, such as molecular identification in the case of heteroderids or some Meloidogyne species. L’identification des espèces pour l’étude de la biodiversité dans le phylum Nemata est définie comme la possibilité d’identifier n’importe laquelle des 12 000 espèces décrites du groupe et d’être capable de reconnaître que le spécimen étudié appartient à une espèce non encore décrite. En outre, ce type d’identification à grande échelle doit pouvoir être pratiqué par des biologistes qui ne sont pas des taxinomistes. Il est montré que les aides imprimées à l’identification sont trop rigides et trop peu fiables et que l’identification moléculaire est encore de portée trop limitée pour être utilisables dans ce contexte. Seuls les outils d’identification assistée par ordinateur sont suffisamment flexibles, fiables et généraux pour permettre à un non taxinomiste d’accomplir les identifications définies plus haut. Pourtant, une revue des outils existants et des approches utilisées montre qu’ils sont incapables d’atteindre l’objectif fixé. La fonctionnalité d’un système d’identification général capable de résoudre les problèmes soulevés par l’utilisation d’outils informatisés est ensuite décrite. Ce système (décrit par les auteurs du présent article sous le nom de Genisys) doit comprendre une base de données avec tous les caractères inclus dans les descriptions publiées des espèces connues et un ensemble d’outils d’identification intégrés. L’un de ces outils devrait permettre d’exporter les données sous des formats utilisables par les outils existants d’identification et de systématique. D’autres outils devraient être développés pour mettre en œuvre de nouvelles approches. Un outil de guidage aiderait le non-spécialiste en lui suggérant les outils informatiques à utiliser successivement dans le cadre d’une session d’identification ou en le dirigeant vers d’autres approches telles que l’identification moléculaire dans le cas de certains Hétérodérides et d’espèces de Meloidogyne.

Zanthoxylum Bungeanum

Zanthoxylum armatum DC., belonged to the family Ruteacea, is a medicinal plant used to cure many diseases. DNA barcoding was used as a tool for molecular identification of Zanthoxylum armatum DC. species from Balakot Pakistan. In the present study four DNA barcodes including matk, rbcl, ITS and trnH-psbA were used. The sequenced data were analyzed by using BLASTn at NCBI, FASTA and Mega 7.0 software. During PCR analysis, 3 DNA barcodes ITS, rbcl and trnh-psbA were successfully amplified and showed the 100% sequencing success. Furthermore, these barcode markers showed 99-100% sequence similarity with the reference sequences at the BLASTn. The further analysis revealed the sequence similarity of investigating marker with Zanthoxylum armatum (MH016484.1), Zanthoxylum nitidum (FN599471.1) and Zanthoxylum bungeanum (MF097123.1) respectively. The current finding provides the basis for sequenced data of Z. armatum to be used in future for molecular discrimination among the plant species from Pakistan and it is concluded that combination of diverse kind of barcoding markers could be helpful in proper identification of species at lower taxonomic level.

Tract Infections

Background: Acute respiratory tract infections (ARTI) are a major threat in children all around the world. Adenovirus is one of the most important pathogens causing respiratory tract infections in children. Adenovirus (AdV) respiratory tract infections is caused mainly by species B, C and E. Accurate and rapid identification of AdV respiratory tract infection is important to avoid unnecessary antibiotic prescription and prevents AdV-related outbreaks. Objectives: This study aimed to identify the most prevalent species of adenovirus causing ARTI in pediatric patients hospitalized at Benha University Hospital which were diagnosed by tissue culture and direct immunofluorescence (DIF) test and compare them with polymerase chain reaction (PCR) as a gold standard method. Methodology: This study was conducted on 60 pediatric patients suffering from ARTI admitted to Benha University Hospitals. Adenovirus was detected by DIF test and isolated by tissue culture. Molecular identification of species- specific adenovirus was done by PCR. Results: Out of 60 cases, 35% were Adenovirus positive by PCR. AdV-B was the most prevalent identified species (76.2%) followed by AdV-C (19.0%) and AdV-E (4.8%). The sensitivity and the specificity of tissue culture and DIF test were 90.5%, 100%, 61.9%, 97.4%, respectively. Conclusion: AdV was encountered in one-third of admitted pediatric Egyptian patients with ARTI in Benha University Hospital. PCR was useful for rapid diagnosis of adenovirus infections with higher sensitivity than other methods.
