Rickettsia is an important pathogenic entity among tick-borne diseases (TBD), which are considered serious emerging public health problems globally. In India, though the widespread distribution of ticks and TBD has been documented, its real burden remains underreported. a preliminary attempt, rickettsial surveillance was carried out in collected from Sirumalai, Eastern Ghats Tamil Nadu, India b...

The organization, structure, and nucleotide variability of the ribosomal repeat unit was compared among families, genera, and species of cockroaches (Insecta:Blattodea). Sequence comparisons and molecular phylogenetic analyses were used to describe rDNA repeat unit variation at differing taxonomic levels. A reverse similar 1200 bp fragment of the 28S rDNA sequence was assessed for its potential...

We characterized two endophyte fungi from the leaves of Astragalus membranaceus in Korea. The isolated strains were identified on the basis of the morphological characters and sequences analysis of the internal transcribed spacer and large subunit regions of the rDNA and β-tubulin gene. To the best of our knowledge, this is the first report of Diaporthe oncostoma and Diaporthe infecunda in Kore...

Eleven clinical and veterinary strains of filamentous Basidiomycetes were compared with 15 reference strains representing the orders Aphyllophorales and Agaricales. The methods used were restriction analysis of small subunit (18S) (SSU) rDNA and internal transcribed spacers (ITS) 1 and 2 and variable domain 9 (V9)-ITS1 sequencing. Six strains were found to belong to the teleomorph genera Schizo...

The two variable domains D1 and D2 near the 5' end of the 28S ribosomal RNA gene (large subunit rRNA) have been sequenced for Vespa crabro. The sequence was aligned to corresponding rDNA regions of the wasp species Nasonia vitripennis, Melittobia digitata and the fruit fly Drosophila melanogaster. We analysed the nucleotide composition and sequence similarity for the different regions of the in...

Aim Fungi make up a large, ecologically important group of eukaryotes that has been neglected in historical biogeography. In this study, molecular phylogenies and molecular clock dating were used to infer historical biogeography of the shiitake genus, Lentinula Earle, which occurs in both the Old World and New World. The major goals of this study were to determine if the Old World and New World...

The genus Coolia A. Meunier 1919 has a global distribution and is common member of epiphytic dinoflagellate assemblages in neritic ecosystems. monotis the type species was only known for 76 years. Over past few decades, molecular characterization unveiled two complexes that group morphologically very similar species, so their limits are often unclear. To provide new knowledge on biogeography co...
