The genetic diversity of 23 oral Fusobacterium nucleatum isolated from 15 periodontal patients, eight from seven healthy subjects, nine from nine AIDS patients and two from two Cebus apella monkeys were analyzed. EcoRI restricted the bacterial DNA and 28 ribotypes grouped from A to J groups were obtained. Isolates formed 24 ribotypes which were contained into A, B, C, D, E and F groups, and thr...

The increased occurrence of Fusarium-mycotoxins in Norwegian cereals over the last decade, is thought to be caused by increased inoculum resulting from more cereal residues at the soil surface as a result of reduced tillage practices. In addition, weather conditions have increasingly promoted inoculum development and infection by Fusarium species. The objective of this work was to elucidate the...

Isolates of Newcastle disease virus (NDV) from chicken cases were obtained from various locations in Taiwan during 2003-2006 and were genotypically analyzed by using reverse transcription polymerase chain reaction (RT-PCR) with primers specific to the viral fusion (F) protein gene (534 bp). Part of the amplified F protein DNA product (nucleotide sequence 47-418) and the deduced amino acid seque...

In a course of survey during growing seasons of 2002-04, various fields and pastures in 23 Iranian provinces were sampled. Some 1200 isolates of Fusarium from root, crown, stem and spike of various plants belonging to the family Poaceae were recovered using Nash-Snyder selective medium and purified on potato dextrose agar (PDA). Based on morphological characteristics, 32 Fusarium species were i...

The antifungal activity of secondary lichen metabolites extracted by means acetone and ethanol from Cetraria islandica, Cladonia mitis, C. rangiferina, Pseudevernia furfuracea Usnea dasopoga on the pathogenic fungi Fusarium oxysporum F. avenacuem was examined. compounds tested after their mixture with PDA medium before solidification. most active extracts inhibiting growth fungal mycelia contai...

Fusarium avenaceum (Fr.) Sacc. is an important phytopathogen. Fight against F. includes primarily fungicide usage. However, novel strategies are needed in a struggle with avenaceum. In this study, terpinolene was used as antimicrobial agent, and the harmlessness of tested on two contrast barley genotypes, Hordeum vulgare L. cv. Cervoise H. Premium. Firstly, minimum inhibitory concentration (MIC...

Isolates of Fusarium were discovered in peat soil samples collected from peat swamp forest, waterlogged peat soil, and peat soil from oil palm plantations. Morphological characteristics were used to tentatively identify the isolates, and species confirmation was based on the sequence of translation elongation factor-1α (TEF-1α) and phylogenetic analysis. Based on the closest match of Basic Loca...
