The clinical picture of Ochrobactrum anthropi infection is not well described because the infection is rare in humans and identification of the pathogen is difficult. We present a case of O. anthropi bacteremia that was initially misidentified as Ralstonia paucula and later identified by 16S rRNA sequencing and recA analysis.
Although Ochrobactrum anthropi is an opportunistic pathogen in immunocompromised patients, it is increasingly being recognized to be a causative agent in healthy hosts. In this paper, we report a case of O. anthropi endocarditis and septic shock in a patient who had no prosthetic valve or rheumatic heart disease, in contrast to previous reports.
Azospirillum lipoferum and Pyricularia oryzae laccases were compared, using several substrates and inhibitors. Sixteen phenolic or nonphenolic compounds were found to be substrates of both fungal and bacterial laccases. In the presence of different phenol oxidase inhibitors, P. oryzae and A. lipoferum laccase activities had similar properties.
Protein-enriched pea flour is toxic and repellent to three major stored grain pests, the rice weevil, Sitophilus oryzae (L.), the red flour beetle, Tribolium castaneum (Herbst) and rusty grain beetle, Cryptolestes ferrugineus (Stephens). A unique and valuable aspect of the protein-enriched pea flour is that it is not toxic several parasitoids that are associated with two of these insect pests. ...
Genome dynamics of pathogenic organisms are driven by pathogen and host co-evolution, in which pathogen genomes are shaped to overcome stresses imposed by hosts with various genetic backgrounds through generation of a variety of isolates. This same principle applies to the rice blast pathogen Magnaporthe oryzae and the rice host; however, genetic variations among different isolates of M. oryzae...
Rice suffers dramatic yield losses due to blast pathogen Magnaporthe oryzae. Pseudomonas chlororaphis EA105, a bacterium that was isolated from the rice rhizosphere, inhibits M. oryzae. It was shown previously that pre-treatment of rice with EA105 reduced the size of blast lesions through jasmonic acid (JA)- and ethylene (ETH)-mediated ISR. Abscisic acid (ABA) acts antagonistically toward salic...
Agrobacterium, Sinorhizobium, and Ochrobactrum are genera closely related to Brucella but, in contrast to the latter, are not pathogenic for humans and animals. We studied by an indirect enzyme-linked immunosorbent assay (ELISA) the reactivities of brucellosis sera against cytosolic (CYT) and membrane (MA) antigens from these nonpathogenic bacteria, and we evaluated the potential usefulness of ...
چکیده ترکیبات سمی و بازدارنده موجود در فرآوردههای هیدرولیزی مواد لیگنوسلولزی از قبیل اسید استیک و ترکیبات فنلی، مشکل اصلی فرآیند تبدیل بیوشیمیایی مواد لیگنوسلولزی به سوختهای زیستی مانند بیواتانول میباشند. در این تحقیق، عملکرد چهار قارچ فیلامنتوس Rhizopus oryzae، Mucor indicus، Neurospora intermedia و Aspergilus oryzae در محیط کشتهای سنتزی حاوی صفر، سه، پنج و هفت گرم بر لیتر اسید استیک بر رو...
To search for virulence effector genes of the rice blast fungus, Magnaporthe oryzae, we carried out a large-scale targeted disruption of genes for 78 putative secreted proteins that are expressed during the early stages of infection of M. oryzae. Disruption of the majority of genes did not affect growth, conidiation, or pathogenicity of M. oryzae. One exception was the gene MC69. The mc69 mutan...
Rice blast, caused by the fungus Magnaporthe oryzae, is one of the most devastating diseases of rice. To understand the molecular basis of Pi5-mediated resistance to M. oryzae, we cloned the resistance (R) gene at this locus using a map-based cloning strategy. Genetic and phenotypic analyses of 2014 F2 progeny from a mapping population derived from a cross between IR50, a susceptible rice culti...
