A total of 95 isolates, belonging to 33 species of five dermatophyte genera, i.e. Arthroderma (15 species), Chrysosporium (two), Epidermophyton (one), Microsporum (three) and Trichophyton (12), were studied using internal transcribed spacer 2 (ITS2)-PCR-RFLP analysis (ITS2-RFLP), consisting of amplification of the ITS2 region, restriction digestion with BstUI (CG/CG) and restriction fragment le...

PREMISE OF THE STUDY DNA metabarcoding has broad-ranging applications in ecology, aerobiology, biosecurity, and forensics. A bioinformatics pipeline has recently been published for identification using a comprehensive database of ITS2, one of the common plant DNA barcoding markers. There is, however, no corresponding database for rbcL, the other primary marker used in plants. METHODS Using pu...

The bivalve family Ostreidae has a worldwide distribution and includes species of high economic importance. Phylogenetics and systematic of oysters based on morphology have proved difficult because of their high phenotypic plasticity. In this study we explore the phylogenetic information of the DNA sequence and secondary structure of the nuclear, fast-evolving, ITS2 rRNA and the mitochondrial 1...

leishmaniasis include several clinical manifestations, mostly cutaneous, visceral and mucosal (1, 2). various species can lead to diverse clinical presentations. thus species identification contribute to proper management (3). localized leishmania lymphadenitis (lll) is a distinct entity in clinicopathologic field presenting with isolated lymphadenitis and possible cocomitant cutaneous lesion i...

The data of the is presented. technology allows to identify entire spectrum organisms in an experimental sample per one cycle, while separate study for each potentially contained component previously was required. An integrated approach submitted as a method early diagnosis causative agents main fungal diseases during silver birch ( Betula pendula Roth ) and downy pubescens Ehrh. plants. It bas...

Mechanisms of ITS2 excision from pre-rRNA remain largely elusive. In mammals, at least two endonucleolytic cleavages are involved, which result in the transient accumulation of precursors to 5.8S rRNA termed 8S and 12S RNAs. We have sequenced ITS2 in four new species of the Mus genus and investigated its secondary structure using thermodynamic prediction and comparative approach. Phylogenetic e...

The aim of this study was to investigate the level of evolutionary divergence among five isofemale lineages of Metopolophium dirhodum Walker (Hemiptera: Aphididae) using sequences of the Internal Transcribed Spacer (ITS) of ribosomal DNA (rDNA). These isofemalelineages were derived from parthenogenetic females, previously genetically characterized by having strong association of RAPD (Random Am...

Abstract Background The malaria mosquito Anopheles punctipennis , a widely distributed species in North America, is capable of transmitting human and actively involved the transmission ungulate parasite Plasmodium odocoilei . However, molecular diagnostic tools based on Internal Transcribed Spacer 2 (ITS2) ribosomal DNA are lacking for this species. former member maculipennis complex but its sy...

introduction: follicle stimulating hormone (fsh) is one of the pituitary glycoproteines that it consists of two subunits alpha and beta. the beta subunit is responsible for the biological activity of fsh. the aim of present study was isolation of the β subunit coding sequence containing its signal sequence from human genome and then cloning of the isolated sequence in ppic9 shuttle vector under...

Food-borne fluke infections/trematodiases are emerging as a major public health problem worldwide with over 40 million people affected and over 10% of world population at risk of infection. The major concentration of these infections is in Southeast Asian and Western Pacific Regions, where the epidemiological factors (including the prevalent socio-cultural food habits) are conducive for transmi...
