Strain FF7(T) was isolated from the peritoneal fluid of a 44-year-old woman who suffered from pelvic peritonitis. This strain exhibited a 16S rRNA sequence similarity of 94.8 % 16S rRNA sequence identity with Haemophilus parasuis, the phylogenetically closest species with a name with standing in nomenclature and a poor MALDI-TOF MS score (1.32 to 1.56) that does not allow any reliable identific...

Mycobacterium sp. strain KR20, which was isolated from a polycyclic aromatic hydrocarbon (PAH) contaminated soil of a former gaswork plant site, metabolized about 60% of the fluoranthene added (0.5 mg ml(-1)) to batch cultures in mineral salts medium within 10 d at 20 degrees C. It thereby increased its cell number about 30-fold and produced at least seven metabolites. Five metabolites, namely ...

Moderately thermophilic, acidophilic, spore-forming bacteria (146 strains) were isolated from various beverages and environments. Based on the results of sequence analysis of the hypervariable region of the 16S rRNA gene, eight of the strains represent novel species of the genus Alicyclobacillus. These strains were designated 3-A191(T), 4-A336(T), 5-A83J(T), 5-A167N, 5-A239-2O-A(T), E-8, RB718(...

Seven new mono- and bis-furanones, pezizolides A-G (1-7), have been isolated from the crude extract of the endolichenic fungus Peziza sp. inhabiting the lichen Xanthoparmelia sp. The structures of the new compounds were elucidated mainly by NMR and MS methods. The absolute configuration of 1-4 was assigned by the application of CD exciton chirality method, and 1 was further supported by electro...

Background: Cutaneous manifestations are commonly observed in the neonatal period. It is important to differentiate physiologic skin lesions from pathologic ones to avoid parents’ concerns. Regarding this, the current study aimed to investigate the frequency and localization of salmon patch (SP) and Mongolian spot (MS) in Iranian newborns to assess the potential relationship between the neonata...

The aim of the present study was to evaluate phytohormone production by symbiotic and saprophytic actinomycetes isolated from the actinorhizal plant Ochetophila trinervis which had previously proved to stimulate nodulation by Frankia. Three saprophytic strains out of 122, isolated from the rhizosphere of this plant with multiple enzymatic activities were selected for plant growth experiments in...

Pseudomonas sp. strain DJ77, which was described as an aromatic-degrading bacterium, was investigated to clarify its taxonomic position. Phylogenetic analysis based on 16S rDNA sequences indicated that the strain belonged to the genus Sphingomonas and formed a monophyletic clade with the type strains of Sphingomonas chlorophenolica, Sphingomonas herbicidovorans and Sphingomonas yanoikuyae with ...

Mycoplasma synoviae (MS) is a pathogen responsible for respiratory and locomotor disorders and causes major economic losses in poultry industry. Early and accurate diagnosis of MS infection plays a major role in control of the infection. This study was conducted to characterize Iranian field isolates of MS isolated from broiler chickens of West Azarbaijan province (Northwest of Iran), ...
