Five species (28 strains) of actinomycetes isolated from tobacco were tested for antagonism against 12 species of storage and field fungi associated with tobacco. Two strains of Streptomyces albus were antagonistic against all test fungi. The actinomycetes grew more rapidly, produced more pigment,
Street marijuana, commercial cigarettes and pipe tobaccos were studied for the presence of fungi and actinomycetes associated with hypersensitivity pneumonitis. Aspergillus species and thermophilic actinomycetes were isolated from the smoking materials. In addition, Aspergillus fumigatus spores were
Soil microorganisms play a crucial role in cycling soil nutrients and providing organic nutrients for plant growth and development. Fertilisation balances soil fertility and quality, and affects soil microbial communities. Fertilisation is a frontier subject in agricultural and environmental
Growth inhibition towards Rhizopus nigricans, Fusarium oxysporum f. sp. radicis-lycopersici, Verticillium albo-atrum and Pythium ultimum was observed in vitro using a purified chitosanase from an actinomycete, Streptomyces sp, strain N174. The corresponding gene, with its own signal peptide, was
Field experiments were conducted in Shilin and Xundian respectively to study the diffe- rence of rhizosphere microbe quantity and functional diversity with plate culture method and Biolog technique among Hongda (high susceptibility, S), Yun87 (middle resistance, MR) and K326 (high resistance, R) ,
An extremely infrequent episode of nasopharyngeal actinomycosis associated with squamous adenocarcinoma occurred in an HIV-infected male patient with a previous diagnosis of AIDS, treated with combined antiretroviral therapy taken with insufficient adherence, such that a satisfactory immune system
Clavibacter michiganensis subsp. michiganensis is an actinomycete, causing bacterial wilt and canker disease of tomato (Solanum lycopersicum). We used virus-induced gene silencing (VIGS) to identify genes playing a role in host basal defense response to C. michiganensis subsp. michiganensis
Two Gram-staining positive, aerobic and non-motile actinomycete strains, designated YIM 2047X(T) and YIM 2047D, were isolated from tobacco root samples collected from Shiling county, Yunnan province, South-West China. The isolates grew at 15-40 °C, pH 6.0-8.0 and 0-4.5 % NaCl (w/v). The whole-cell
OBJECTIVE
Though plant metabolic changes are known to occur during interactions with bacteria, these were rarely challenged for pharmacologically active compounds suitable for further drug development. Here, the occurrence of specific chemicals with antiproliferative activity against human cancer
Work on soils suppressive to Thielaviopsis basicola-mediated tobacco black root rot has focused on antagonistic pseudomonads to date. The role of non-Pseudomonas rhizosphere populations has been neglected, and whether they differ in black root rot-suppressive versus -conducive soils is unknown. To
The concentrations of airborne microbes, endotoxins and total dust were measured in one cigar and two cigarette factories in order to evaluate the risk of respiratory symptoms. The role of humidifiers as a source of microbes was investigated. Air samples for the analyses were collected near workers'
The development of a topical microbicide blocking the sexual transmission of HIV-1 is urgently needed to control the global HIV/AIDS pandemic. The actinomycete-derived lectin actinohivin (AH) is highly specific to a cluster of high-mannose-type glycans uniquely found on the viral envelope (Env).
Although much of the evidence in environmental lung disease remains equivocal, some environmental exposures are known to be clinically relevant. Ambient air pollution remains of concern as a source of morbidity, particularly for susceptible populations such as persons with asthma, chronic
BACKGROUND
The severe evolution for some patient presenting with osteoradionecrosis, even if classified in the same stages as other patients, suggests that there are aggravating factors.
METHODS
A retrospective study was made between 1992 and 2002 on all patient operated for mandibular
