Endophytic fungi were isolated from healthy leaf and root samples of Taraxacum coreanum. Of the 72 isolates recovered, 39 were from leaves and 33 from roots with an isolation frequency of 54% and 46%, respectively. Based on ITS sequence analysis, 72 isolates were classified into 19 genera of which 17 were under the phylum Ascomycota and 2 were under Basidiomycota. Diverse genera were found and ...

OBJECTIVES Successful clones of Neisseria gonorrhoeae multiantigen sequence typing sequence type (ST) 1407 and ST1407-related genotypes have been reported to cause cefixime and ceftriaxone treatment failure in many countries. We characterized the 47 isolates of a strain cluster of ST4378, a genotype that differs in the porB sequence by only one nucleotide from ST1407, in Taiwan during April 200...

A newly identified 1 kb DNA fragment amplified by PCR using (AG)8T inter-simple sequence repeats (ISSR) primer and a 631 bp segment of 16S rRNA ribosomal gene amplified by PCR using reported primers were labeled with a alpha32P dCTP for use as DNA probes. These probes were hybridized with DNA extracted from 19 standard pathogenic serovars, 3 standard saprophytic serovars, 33 pathogenic isolates...

The Khoy Ophiolitic Complex (KOC) as a part of Tethyan, Izmir-Ankara- Erzincan and Bitlis-Zagros sutures of South East (SE) Turkey is broadly exposed around Khoy region (NW Iran). This complex comprises dismembered fragments of mantle lithosphere, obducted oceanic lithosphere and parts of volcanic arc remnants. The Khoy Ophiolitic Complex can be structurally divided into two major eastern and w...

BACKGROUND & OBJECTIVES Though not frequently but there are reports showing phacoemulsifiers as a potent source of infection in post-operative cases of endophthalmitis. This study was carried out to find antibiogram and genetic relatedness between Pseudomonas aeruginosa isolates from a post-cataract surgery endophthalmitis outbreak (3 patients) and internal tubings of 5 phacoemulsifiers. METH...

Outbreaks of diarrhea in child day-care centers (DCC) are common. This study was undertaken to evaluate the molecular epidemiology of an outbreak of diarrhea due to Shigella sonnei. This outbreak involved 25 of 52 (48%) DCC children and 14 of 132 (11%) teachers and household contacts. S. sonnei isolates from nine children and five contacts were characterized by antimicrobial susceptibility, pla...

Three different methodologies, reduction of litmus milk (LM) and acidification of arabinose (ARA), acidification of methyl-alpha-D-glucopyranoside (MGP), and rapid motility (RM), for differentiating isolates of Enterococcus casseliflavus and Enterococcus gallinarum (intrinsically vancomycin-resistant enterococci [IVRE]) from Enterococcus faecalis and Enterococcus faecium were evaluated. All 33 ...

genus trichoderma is a monophyletic fungus which some their species is known as biocontrol agent. this study was carried out for phylogenetic analysis of some isolates of the genus trichoderma. in this study 73 sequences (including 33 sequences from t. aspereluum, t. brevicompactum, t. capillare, t. harzianum, t. koningiopsis, t. pleuroticola and t. virens and 40 sequences obtained from geneban...

The occurrence of strains resistant to metronidazole is causing failure of the 4-drug regimen for eradication of Helicobacter pylori in the Islamic Republic of Iran. This study compared the in vitro efficacy of furazolidone with metronidazole, clarithromycin, amoxicillin and tetracycline in 70 H. pylori isolates from dyspeptic patients. Of the isolates, 33% were resistant to metronidazole but a...
