The aim of this study was to investigate the Stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. The volatile constituents from the aerial parts of Stachys turcomanica growing wild in Iran were obtained by hydrodistillation and analyzed by GC and GC-MS. In the GC-MS analysis, Forty-six components representing 81.1% of the oil were identifie...

background and objectives: to find antagonistic bacteria with potential antifungal activity against some pathogenic fungi, including aspergillus niger , a. flavus, fusarium moniliforme and penicillium marneffei , a total of 148 agricultural soil samples from different sites of tehran were examined.  materials and methods: antagonistic soils were selected by screening against a. niger on glucose...

to determine the prevalence of bacterial mastitis in cattle, milk samples positive for california mastitistest (cmt) were cultured during a period of almost 4 years. the bacterial species isolated from 2904 milksamples studied were coagulase negative staphylococcus sp. in 879 (30.27%) samples, streptococcusagalactiae in 642 (22.11%), s. dysgalactiae in 332 (11.43%), e. coli in 295 (10.16%), sta...

background :   vibrio species including v. cholera , v. mimicus , v. parahaemolyticus , and v. vulnificus may cause gastrointestinal diseases after seafood consumption, and wound infections in swimmers and fishermen after exposing to seawater. this study determined the prevalence of the four vibrio species in tonkabon and ramsar recreational beach water (approximately 200 meter far from the pla...

conclusions the present data confirmed systemic and topical anti-inflammatory effects of stachys pilifera which is comparable to indomethacin. results acute toxicity study of the extract showed that no rats were killed at 5000 mg/kg (ld50 > 5000 mg/kg). the extract (100 and 200  mg/ kg) significantly suppressed carrageenan-induced paw edema 1, 2, 3, and 4  hours after carrageenan challenge in c...

Stachys brachyclada de Noé ex Coss. (Lamiaceae) is a quite rare medicinal plant endemic to the Mediterranean basin. In this study, seven secondary metabolites from methanol extract of its leaves have been isolated and identified by combination chromatographic spectroscopic methods (1D 2D NMR experiments ESIMS analysis). They include one ethyl 4-hydroxybenzoate (1), three acylated flavone glycos...

background: monitoring of indicator and pathogenic microorganisms is essential for proper composting. the aim of this study was to evaluate the change in population of coliform bacteria and salmonella spp. in composting process of municipal wastes and after its application on soil. methods: the samples were taken from each raw waste pile, initial pile, and active phase pile, cooling phase pile ...

objective: microorganisms are responsible for many problems in industry and medicine because of biofilm formation. therefore, this study was aimed to examine the effect of thymus vulgaris (t. vulgaris) extracts on the planktonic form and biofilm structures of six pathogenic bacteria. materials and methods: antimicrobial activities of the plant extracts against the planktonic form of the bacteri...

anamorphs of pleosporaceae are important plant pathogenic fungi. despite efforts to clarify phylogenetic relationships of this group there is still uncertainty about taxonomic position of some genera. therefor to elucidate relationships among anamorphic form of some pleosporalean taxa, the internal transcribed spacer (its) and rna polymerase second largest subunit (rpb2) of some members were de...
