Conjugative tetracycline resistance plasmids from 15 Clostridium perfringens isolates from piggeries were analyzed by restriction endonuclease digestion and agarose gel electrophoresis. Seven isolates from one farm were found to carry a 47-kilobase pair (kb) plasmid, pJIR5, which had EcoRI, XbaI, and ClaI profiles that were identical to those of a previously characterized plasmid, pCW3. An isol...

In 1995, the rate of isolation of Enterobacter aerogenes in the Saint-Pierre University Hospital in Brussels, Belgium, was higher than that in the preceding years. A total of 45 nosocomial E. aerogenes strains were collected from 33 patients of different units during that year, and they were isolated from 19 respiratory specimens, 13 pus specimens, 7 blood specimens, 4 urinary specimens, 1 cath...

a total of twenty seven bacterial strains were isolated from cankerous tissues of apricot, nectarine, peach, plum, sour cherry and sweet cherry trees in tehran province and identified as pseudomonas syringae pv. syringae (pss), the causal agent of the bacterial canker disease, on the basis of lopat (levan production, oxidase test, potato rot, arginine dihydrolase and tobacco hypersensitive ...

Tutorial dialogue has been the subject of increasing attention in recent years, and it has become evident that empirical studies of human-human tutorial dialogue can contribute important insights to the design of computational models of dialogue. Students with particular characteristics may have specific dialogue profiles, and knowledge of such profiles could inform the design of tutorial dialo...

The present study was aimed to detect the plasmid profile, the role of plasmid associated multiple antibiotic resistance of Vibrios isolated from coastal waters of Kerala. The isolated plasmids from antibiotic resistant Vibrios were tested for the presence of integrons using polymerase chain reaction (PCR) to elucidate the presence of plasmid borne integron, a key element in horizontal gene tra...

BACKGROUND & OBJECTIVES The nosocomial human pathogen Acinetobacter baumannii has high propensity to develop resistance to antimicrobials and to become multidrug resistant (MDR), consequently complicating the treatment. This study was carried out to investigate the presence of resistant plasmids (R-plasmids) among the clinical isolates of A. baumannii. In addition, the study was performed to ch...

The areal extent and spatial distribution of evergreen forests in the tropical zones are important for the study of climate, carbon cycle and biodiversity. However, frequent cloud cover in the tropical regions makes mapping evergreen forests a challenging task. In this study we developed a simple and novel mapping algorithm that is based on the temporal profile analysis of Land Surface Water In...
