Diarrhea is a leading cause of illness and death, particularly in developing countries. Enteropathogenic Escherichia coli, enterotoxigenic E. coli (ETEC), enteroinvasive E. coli, enterohemorrhaghic E. coli (EHEC), enteroaggregative E. coli (EAEC) and diffusely adherent E. coli (DAEC) have been associated with diarrheal disease in different parts of Africa, particularly among young children, HIV...
just as motivation is important in sla research, demotivation constitutes an important factor, too. there are many studies done on demotivation and burnout of teachers. many of these studies have been conducted on one or two aspects of english instruction. consequently, there are few studies which have been done on more than two aspects of english teaching. the aim of this study is to find out ...
We have analyzed the karyotype of the rice blast fungus, Magnaporthe grisea, by using pulsed-filed gel electrophoresis. We tested whether the electrophoretic karyotype of an isolate was related to its pathotype, as determined by infection assays, or its genetic lineage, as determined by DNA fingerprinting. Highly reproducible electrophoretic karyotypes were obtained for a collection of U.S. and...
Autotransporter (AT) protein-encoding genes of diarrheagenic Escherichia coli (DEC) pathotypes (cah, eatA, ehaABCDJ, espC, espI, espP, pet, pic, sat, and tibA) were detected in typical and atypical enteropathogenic E. coli (EPEC) in frequencies between 0.8% and 39.3%. Although these ATs have been described in particular DEC pathotypes, their presence in EPEC indicates that they should not be co...
AIM We aimed to develop a multiplex PCR assay for specific detection of EPEC and EHEC pathotypes based on specific marker genes. BACKGROUND About 2.5 million infant's morbidity in developing countries occurs by E.coli pathotypes because of diarrhea and intestinal diseases. The traditional phenotypic methods are time consuming and sometimes detection and differentiation of the pathotypes are n...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
the present study aimed at investigating the relationship between iranian efl teachers’ classroom management orientations and their teaching styles. additionally, the difference between male and female teachers’ teaching styles and classroom management orientations and their relationship with experience and age were explored. three hundred efl teachers filled in attitudes and beliefs on classro...
Resistance to Meloidogyne chitwoodi was introgressed from Solanum bulbocastanum into the cultivated gene pool of potato. A single dominant gene is responsible for resistance to race 1 reproduction on the root system. An additional form of resistance was discovered in certain advanced backcross clones. A BC(5) clone, PA99N82-4, resisted invasion of tubers by available nematode juveniles whether ...
Clubroot disease caused by Plasmodiophora brassicae is one of the most serious diseases in Brassica crops worldwide. In this study, the pathotypes of 12 Korean P. brassicae field isolates were determined using various Chinese cabbage including 22 commercial cultivars from Korea, China, and Japan, and 15 inbred lines. All P. brassicae isolates exhibited the typical clubroot disease on non-clubro...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
