abstract background: fascioliasis, caused by fasciola hepatica and f. gigantica , has medical and economic importance in the world. molecular approaches comparing tradi­tional methods using for identification and characterization of fasciola spp. are precise and reliable. the aims of current study were molecular characterization of fasciola spp. in west azerbaijan province, iran and then compar...

The most common biological control agents (BCAs) of the genus Trichoderma have been reported to be strains of Trichoderma virens, T. harzianum, and T. viride. Since Trichoderma BCAs use different mechanisms of biocontrol, it is very important to explore the synergistic effects expressed by different genotypes for their practical use in agriculture. Characterization of 16 biocontrol strains, pre...

Cutaneous leishmaniasis (CL), a public health problem in Tunisia, is associated to three species: Leishmania (L.) infantum, L. major and L. killicki. Accurate and sensitive procedures for the diagnostic of Leishmania infection and for species identification are required to enable adequate treatment and appropriate control measures. Several PCR-methods are applied for the diagnosis and the ident...

Eukaryotes have two types of ribosomes containing either 5.8SL or 5.8SS rRNA that are produced by alternative pre-rRNA processing. The exact processing pathway for the minor 5.8SL rRNA species is poorly documented. We have previously shown that the trans-acting factor Rrp5p and the RNA exonuclease Rex4p genetically interact to influence the ratio between the two forms of 5.8S rRNA in the yeast ...

Cyanobacteria of the genus Nodularia form toxic blooms in brackish waters worldwide. In addition, Nodularia spp. are found in benthic, periphytic, and soil habitats. The majority of the planktic isolates produce a pentapeptide hepatotoxin nodularin. We examined the morphologic, toxicologic, and molecular characters of 18 nodularin-producing and nontoxic Nodularia strains to find appropriate mar...

Chronic rhinosinusitis (CRS) rank second at chronic inflammatory diseases in industrialized countries and are an important public health concern. Diagnosis relies on a set of arguments including clinical signs, imaging, histopathologic and mycological analyses of sinus specimens, collected during nasal endoscopy. The sensitivity of fungal cultures is reported to be poor, even when direct examin...

Pseudacrobeles (Pseudacrobeles) curvatus sp. n. was collected from potato fields in Gyeongsangnam-do, South Korea. The new species shares morphological characters typical of the genus Pseudacrobeles, including three lateral incisures that fade posteriorly near the phasmid openings. The new species differs from other Pseudacrobeles species by its smaller body size and a comparatively shorter cor...

Diversity in Pistacia has been evaluated at all molecular levels using the internal transcribed spacer 1 (ITS1) marker three species (Pistacia atlantica subsp. atlantica; vera and terebinthus), compared with other species. Results showed that ITS amplification sequencing, followed by phylogenetic analyses, identify confirm their classification, which revealed it can be used as a marker. Our res...

A variety of genes have been used to type Pneumocystis carinii. In the present study, nucleotide sequence variations in the ITS1 and ITS2 internal transcribed spacer (ITS) regions of the rRNA genes were used to type Pneumocystis carinii f. sp. hominis DNA obtained from the lungs of 60 human immunodeficiency virus-infected individuals. These regions were amplified by PCR, cloned, and sequenced. ...

In 2006/7, 18 cases of cutaneous leishmaniasis (CL) were reported for the first time from Sde Eliyahu (pop. 650), a village in the Beit She'an valley of Israel. Between 2007-2011, a further 88 CL cases were diagnosed bringing the total to 106 (16.3% of the population of Sde Eliyahu). The majority of cases resided in the south-western part of the village along the perimeter fence. The causative ...
