As cactáceas constituem-se de uma família com grande número gêneros e espécies, porém, sua diversidade encontra-se ameaçada, devido a agentes patogênicos que podem comprometer morfologia fisiologia. O objetivo da pesquisa foi verificar ocorrência etiológicos doenças em cactos na região do Brejo paraibano. Os patógenos isolados foram incubados placas Petri contendo meio BDA (batata-dextrose-ágar...

Pineapple (Ananas comosus) is native to South America and widely planted as a fruit crop in the tropics and sub-tropics. This plant is susceptible to a number of fungal diseases of which the most severe is fusariosis. The disease is caused by Fusarium guttiforme and occurs only in South and Central America. The occurrence of a similar disease on pineapples in South Africa has prompted a re-eval...

The aim of the present study was to isolate, identify and observe antibacterial activity of the endophytic fungi against some pathogenic bacteria as well as to optimize various parameters for maximum production of antibacterial bioactive compounds. Endophytic fungi were isolated from Menthe viridis collected from Khamariya, Jabalpur M.P. (India). Screening of endophytic fungi for in-vitro antib...

BACKGROUND Opuntia dillenii is an invasive plant well established in the harsh South-Eastern arid zone of Sri Lanka. Evidence suggests it is likely that the endophytic fungal populations of O. dillenii assist the host in overcoming biotic and abiotic stress by producing biologically active metabolites. With this in mind there is potential to discover novel natural products with useful biologica...

Rhizobium sp. strain TBD182, isolated from a novel hydroponics system, is an antagonistic bacterium that inhibits the mycelial growth of Fusarium oxysporum but does not eliminate the pathogen. We report the draft genome sequence of TBD182, which may contribute to elucidation of the molecular mechanisms of its fungistatic activity.

Marine sponges which are known to own multiple functional properties have created significant interest among the researchers due to their biological activities and impending application in different industries .The aim of this study was to obtained bioactive components of sponges. Gelliodes carnosa sponge was collected from Nay Band Bay (Persian Gulf waters) and antimicrobial activities of crud...

The impact of 10 Fusarium species in concomitant association with Rotylenchulus reniformis on cotton seedling disease was examined under greenhouse conditions. In experiment 1, fungal treatments consisted of Fusarium chlamydosporum, F. equiseti, F. lateritium, F. moniliforme, F. oxysporum, F. oxysporum f.sp. vasinfectum, F. proliferatum, F. semitectum, F. solani, and F. sporotrichioides; Rhizoc...

The in vitro interactions of anidulafungin with itraconazole, voriconazole, and amphotericin B were evaluated by using the checkerboard method. For Aspergillus spp., anidulafungin with amphotericin B showed indifference for 16/26 isolates, while anidulafungin with either azole showed a synergy trend for 18/26 isolates. All drug combinations showed indifference for 7/7 Fusarium sp. isolates.

The trichothecene mycotoxin 3-acetyldeoxynivalenol was transformed by cultures of the diacetoxyscirpenol producer Fusarium sp. strain C37410-90 into four compounds, identified as deoxynivalenol, 15-acetyldeoxynivalenol, 3,15-diacetyldeoxynivalenol and fusarenon-X. The major transformations are the result of specific esterification and de-esterification processes, but the production of fusarenon...
