BACKGROUND Clostridium difficile is a leading infectious cause of health care associated diarrhoea. Several industrialised countries have reported increased C. difficile infections and outbreaks, which have been attributed to the emergent PCR ribotype 027 strain. METHODS AND FINDINGS We conducted a case-case study to compare severity of C. difficile disease for patients with 027 versus non-02...
conclusions the results of pcr-ribotyping indicate that no relationship exists between clinical and meat isolates. we therefore conclude that other sources than meat may function as a vector for ca-cdi. results the overall prevalence of c. difficile with two toxigenic genes including tcda and tcdb was estimated at 4.0%. c. difficile was detected in 2.8%, 2.1%, 3.6% and 6.2% of chopped beef, gro...
this study was an attempt to investigate the effect of using c-test passages on the reading comprehension and incidental vocabulary learning of iranian intermediate efl learners. the participants were 60 male efl learners at kish mehr institute in garmsar. in fact, there were two groups, an experimental group and a comparison group with 30 students in each. the participants were pretested throu...
Recent emergence of a virulent strain of Clostridium difficile demonstrates the importance of tracking C. difficile incidence locally. Our survey of New Jersey hospitals documented increases in the rates of C. difficile disease (by 2-fold), C. difficile-associated complications (by 7-fold), and C. difficile outbreaks (by 12-fold) during 2000-2004.
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
INTRODUCTION The C. difficile BI/NAP 1 hyper virulent strain has been responsible for the nosocomial outbreaks in several countries. The present study describes the infection control strategies utilized to achieve outbreak control as well as the factors associated with a C. difficile BI/NAP 1 hyper virulent strain outbreak in Costa Rica. METHODOLOGY A descriptive analysis of the C. difficile ...
Clostridium difficile (C. difficile) is a common causative agent of pseudomembranous colitis (PMC). C. difficile-associated diarrhea (CDAD) ranges from mild diarrhea to life threatening PMC. Recently, a highly virulent strain of C. difficile polymerase chain reaction ribotype 027 was found in North America, Europe, and Japan. A 52-yr-old woman with anti-tuberculosis medication and neurogenic bl...
Emerging enteric pathogens could have not only more antibiotic resistance or virulence traits; they could also have increased resistance to heat. We quantified the effects of minimum recommended cooking and higher temperatures, individually on a collection of C. difficile isolates and on the survival probability of a mixture of emerging C. difficile strains. While minimum recommended cooking ti...
