Fusarium proliferatum is an important pathogen and causes a great economic loss to fruit industry. Environmental pH-value plays a regulatory role in fungi pathogenicity, however, the mechanism needs further exploration. In this study, F. proliferatum was cultured under two initial pH conditions of 5 and 10. No obvious difference was observed in the growth rate of F. proliferatum between two pH-...

Fusarium species are causal agents of fungal diseases occurring frequently in numerous agriculturally important plants, including potato, garlic and are one of the common pathogens of tomato, causing root rot in the west part of Iran. Therefore, the objectives of this study were to isolate and identify disease-causing Fusarium species from infected tomatoes based on the morphological and molecu...

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...

Natural hybridization between two strains, varieties, or species is a common phenomenon in both plants and animals. Although hybridization may skew established gene pools, it generates population diversity efficiently and sometimes results in the emergence of newly adapted genotypes. Cryptococcus neoformans, which causes the most frequent opportunistic fungal infection in immunocompromised host...

to determine the role of fusarium species associated with sugar beet root  and crown rot, diseased samples were collected  from different fields of sugar beet in iran including khorasan, khuzestan west azarbayejan, qazvin, tehran, kermanshah ,kerman,lorestan ,hamedan,charmahal va bachtiary provinces during growing seasons 1999-2002. in total, 94 isolates of fusarium were obtained. based on morp...

Fumonisin B1 (FB1) and FB2 were isolated from corn cultures of both Fusarium moniliforme and Fusarium proliferatum. Respective concentrations in culture materials of FB1 and FB2 ranged from 960 to 2,350 and 120 to 320 micrograms/g for F. moniliforme and from 1,670 to 2,790 and 150 to 320 micrograms/g for F. proliferatum. Thin-layer chromatography, gas chromatography-mass spectroscopy, high-perf...

colibacillosis caused by avian pathogenic escherichia coli (apec) is an economic threat to the poultry industry throughout the world. some of the virulence genes may enhance the ability of e. coli isolates to grow in the tissues of broilers. the apec strains are assigned to a few distinct phylogenetic groups. the purpose of the present study was to detect the virulence genes and phylogenetic gr...

A total of 50 samples of poultry feed mixtures of Slovak origin were analysed for fumonisin B(1) and B(2) (FB(1), FB(2)) and moniliformin (MON) using SAX-clean up procedure being detected by high pressure liquid chromatography with mass spectrometry (HPLC-MS) and diode array detection (HPLC-DAD), respectively. The samples were also simultaneously investigated for Fusarium species occurrence, an...

BACKGROUND Pokkah boeng disease caused by the Fusarium species complex results in significant yield losses in sugarcane. Thus, the rapid and accurate detection and identification of the pathogen is urgently required to manage and prevent the spreading of sugarcane pokkah boeng. METHODS A total of 101 isolates were recovered from the pokkah boeng samples collected from five major sugarcane pro...
