myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. the classification of myxosporeans is generally based on the morphology of their myxospores. without molecular data, it is very difficult to identify new or existing species. dna sequence information is therefore, a prerequisite to taxonomic and phy...

Members of Nemacheilidae Family, Turcinoemacheilus genus were subjected to molecular phylogenetic analysis in this study. This genus was reported in 2009 to inhabit in Karoon River drainage, in contrary to previous assumption that it was the endemic species in the Basin of Tigris River. It was sampled from three stations placed in different tributaries in Karoon drainage and evaluated to unders...

this study represents phylogenetic analyses of two woody polygonaceous genera calligonum and pteropyrum using both chloroplast fragment (trnl-f) and the nuclear ribosomal internal transcribed spacer (nrdna its) sequence data. all inferred phylogenies using parsimony and bayesian methods showed that calligonum and pteropyrum are both monophyletic and closely related taxa. they have no affinity w...

background: cockroaches are of vital importance medically and hygienically as they can disperse human patho­genic agents and are especially responsible for food contamination and spreading of food borne pathogens. in this study, part of mtdna-coi gene of five common pest cockroaches was tested for diagnostic and phylogenetic pur­poses. methods: we have described barcode region of mtdna-coi gene...

background: the phylogenetic location of chinese spirometra sparganum isolates remains unclear. the aim of this study was to explore the phylogenetic location of the spirometra sparganum isolates from china. methods: the 28s ribosomal dna (rdna) d1 sequences of 14 spirometra sparganum isolates collected from thirteen locations in china were analyzed by using neighbor-joining (nj), maximum parsi...

background: crimean congo hemorrhagic fever virus (cchfv) is a member of the bunyaviridae family and nairovirus genus. it has a negative-sense, single stranded rna genome approximately 19.2 kb, containing the small, medium, and large segments. cchfvs are relatively divergent in their genome sequence and grouped in seven distinct clades based on s-segment sequence analysis and six clades based o...
