Introduction: Anthroponotic cutaneous leishmaniasis (ACL) is still a major public health problem in the northeast and central parts of Iran. This study was designed to compare microscopy and cultivation methods with PCR amplification of kinetoplast DNA and ITS1 followed by RFLP analysis for diagnosis of acute and chronic ACL. Methods: In this study, 66 patients with ACL including 24 acute and 4...

strains of trichoderma harzianum s. l. have a great importance because of affecting mankind by being used as biological control agents against plant pathogens. in the present study, we planned to characterize the phylogenetic structure of t. harzianum recovered from different geographical origins and various habitats in some climates of iran (nc, scd, csw). in order to screen 239 collected tric...

Animal African trypanosomoses (AAT) are caused by flagellated protozoa of the Trypanosoma genus and contribute to considerable losses in animal production in Africa, Latin America and South East Asia. Trypanosoma congolense is considered the economically most important species. Drug resistant T. congolense strains present a threat to the control of AAT and have triggered research into discovery...

Background and aim: Dermatophytosis (tinea, ringworm) is the infection of skin, hair or nail that is caused by various keratinophilic fungi (dermatophytes). Dermatophytosis is a common infection throughout the world including all parts of Iran. As conventional laboratory procedures for identification of different dermatophytes are slow or lack specificity, more rapid and reliable methods are st...

Studies of the human microbiome frequently omit characterization of fungal communities (the mycobiome), which limits our ability to investigate how fungal communities influence human health. The internal transcribed spacer 1 (ITS1) region of the eukaryotic ribosomal cluster has features allowing for wide taxonomic coverage and has been recognized as a suitable barcode region for species-level i...

Schistosomes are parasites of considerable medical and veterinary importance and, therefore, all aspects of their biology have been intensively studied. In contrast, our knowledge of species of the largest genus, Trichobilharzia, is insufficient. Because morphological characterization of Trichobilharzia species provides a limited number of criteria for species determination, molecular data are ...

Distinction between members of the equatorial Africa malaria vector Anopheles moucheti (Evans) s.l. (Diptera: Culicidae) has been based mainly on doubtful morphological features. To determine the level of genetic differentiation between the three morphological forms of this complex, we investigated molecular polymorphism in the gene encoding for mitochondrial cytochrome oxidase b (CytB) and in ...

The application of nuclear rDNA ITS sequences in plant phylogeny and evolution analysis was discussed in this paper. Nuclear rDNA is an important nuclear gene fragment, which had been widely used in phylogenetic studies. The internal transcribed spacer of nuclear rDNA was divided into ITS1 and ITS2 by 5.8S rDNA. The length of ITS1 ranges from 165 bp to 298 bp in angiosperms, and the length of I...
