Tebu (Saccharum officinarum) merupakan tanaman perkebunan penting sebagai penghasil utama gula di Indonesia. Penurunan produksi tebu dalam beberapa tahun terakhir tidak sejalan dengan permintaan yang kian meningkat. Pemuliaan diarahkan untuk mendapatkan varietas-varietas unggul diharapkan memiliki produktivitas tinggi dan tahan terhadap faktor-faktor gangguan dapat menurunkan tanaman. Pengamata...

The fumonisins, a family of food-borne carcinogenic mycotoxins, were first isolated in 1988 (21) from cultures of Fusarium verticillioides (Sacc.) Nirenberg (previously known as Fusarium moniliforme Sheldon). During the same year, the structures of the fumonisins were elucidated (6) and fumonisin B1 was shown to cause equine leukoencephalomalacia (34). There have been numerous publications deal...

Catalase and superoxide dismutase (SOD) activities of virulent and nonvirulent isolates of Staphylococcus aureus were compared. The mean value of catalase activity for intact cell suspensions was 2,773 +/- 1,049 Kat f units (Kat f is defined as the ratio of the velocity constant of catalase at 0 min to the protein content in grams per milliliter); that of nonvirulent isolates was 154 +/- 92 Kat...

Essential oils from Ferulago asparagifolia Boiss., F. galbanifera (Miller) W. Koch, F. humilis Boiss. (Endemic), F. trachycarpa Boiss. growing in Turkey were evaluated against 15 microorganisms for their antifungal and antibacterial activity using an agar tube dilution and microdilution broth susceptibility assay, respectively. The essential oil compositions were investigated by GC/MS. Inhibito...

A variety of toxic secondary metabolites including fumonisins, can be produced by the fungus Fusarium moniliforme and closely related species in section Liseola in large amounts (g/kg in laboratory cultures). Underivatized fumonisins were detected by HPLC using either an evaporative light scattering detector or electrospray MS. Electrospray MS used together with NMR and GC/MS was used to identi...

In order to determine the fumonisin producingisolates of the Fusarium fujikuroi species complex (FFSC), associated with infected spikes, and ear rot of grass plants, we examined 78 samples collected from Kermanshah province, Iran. Based on morphological characters, twenty two isolates assigned to the FFSC and were identified as F. proliferatum (ten isolates), F. verticillioides (seven isolates)...

The outcomes for 73 invasive fusariosis patients treated with voriconazole were investigated. Patients with proven (n = 67) or probable (n = 6) infections were identified from the voriconazole clinical database (n = 39) and the French National Reference Center for Mycoses and Antifungals database (n = 34). Investigator-determined success was a complete or partial response. Survival was determin...

The study aims to identify phylogenetic groups and antibiotic susceptibility of poultry Escherichia coli (APEC) isolates. E. was phenotypically biochemically characterized. Isolates from 8/30 (26.66%) liver, 7/30 (23.33%) heart, 4/30 (13.33%) spleen 37-42 days old vaccinated broiler chickens were assessed. Then the isolates (19/90; 21.11%) phylogrouped by quadruplex genotyping based on presence...
