Among 120 Escherichia coli isolates from Thai patients, 37 and 9 isolates were extended-spectrum beta-lactamase (ESBL) and suspected ESBL producers respectively while 5 E. coli isolates from 120 Thai healthy adults were suspected ESBL producers. Integrase (intl1) gene was detected in 99% of the clinical and 87% of the non-clinical isolates. Among 37 ESBL producers, percent recovery of bla(TEM),...

Biofilms are social entities where bacteria live in tightly packed agglomerations, surrounded by self-secreted exopolymers. Since production of exopolymers is costly and potentially exploitable by non-producers, mechanisms that prevent invasion of non-producing mutants are hypothesized. Here we study long-term dynamics and evolution in Bacillus subtilis biofilm populations consisting of wild-ty...

The effects of uniting separated markets, each monopolized by a producer, into a globalized oligopolistic market, which is regarded as a non-cooperative game, are investigated. The cases where such globalization degrades the profits or surpluses of all producers, are examined. Linear demand and production functions are considered. The revenues of producers and consumers are assumed to be indepe...

Interest and questions about the quality of beef are on the rise due to heightened awareness about the marketing of beef, from procurement and processing to consumer acceptance. Belatedly, producers are now beginning to receive information about the quality of the beef they produce. Consolidations among beef marketers have resulted in better communication between marketers and producers on carc...

the consumption of chemical fertilizers and increasing environmental crisis has emphasized to increase interest in sustainable agriculture. the farmers' knowledge related to sustainable agriculture has an important role in their environmental behaviors. this research investigated factors affecting men and women cotton producers’ knowledge. the survey research was conducted using stratified...

BACKGROUND Studies suggested that the inter-individual differences in metabolizing isoflavone daidzein to equol or O-desmethylangolensin (ODMA) might explain the inconsistency of the soy/isoflavones efficacy on cardiovascular health. OBJECTIVES The study aims to evaluate the relationship between equol and ODMA phenotypes and cardiovascular risks with habitual isoflavone consumption in Chinese...

A general framework for the study of outsourcing is introduced that incorporates dynamics and heterogeneity among both upstream and downstream producers to mimic an exit approach (Hirschman, 1970) to building vertical relations. The environment is one of search friction and incomplete contracts, where final-good producers require a specialized input and, upon matching with a supplier, can only ...

INTRODUCTION From 2001-2009 there have been numerous community alerts and notifications about the rocket salad produced in Italy and distributed in Europe. Our study describes the evolution of the microbial quality of ready to eat rocket salad during shelf life among three different Italian producers. MATERIAL AND METHODS Total Mesophilic Count (TMC) and Escherichia coli (EC) count were measu...
