enterococci are important because of their role as the leading cause of nosocomial infections which have a significant role in the dissemination and persistence of antimicrobial resistance genes. methods: in this study, we determined the distribution of enterococcal species in the sewage treatment plants in iran. furthermore, we improved a rapid and specific pcr method using primers (soda and d...

We present a solution to the Maxmin u/E parameters estimation problem of possibility distributions in m-dimensional case. Our method is based on geometrical approach, where minimal area enclosing ellipsoid is constructed around the sample. Also we demonstrate that one can improve results of well-known algorithms in fuzzy model identification task using Maxmin u/E parameters estimation. Keywords...

background: coccidiosis is an intestinal disease of chickens caused by various species of proto­zoan parasites within the genus eimeria . diagnosis and genetic characterization of different spe­cies of eimeria are central to the prevention, surveillance, and control of coccidiosis. the aim of this study was to detect different chicken eimeria species from several areas in khuzestan, south­west ...

background:the bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. objectives:the aim of this research was to investigate the bacterialcontamination status, with emphasis on escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated escherichia coli. methods:ato...

there is a great interest in developing rapid analytical methods and provide appropriate parametersfor quantitative analysis of compounds derived from refractory pollutants. such methods are important forroutine quality control analysis of an effluent before being discharged into the environment. therefore, a rapid methodology for identification and quantification of some aliphatic acids is pro...

background and objective: antibiotic resistance is increasing, especially in healthcare-associated infections causing significant public health concerns worldwide. national information is required to make appropriate policies, update list of essential drugs for treatment, and evaluate the effects of intervention strategies. a nationwide surveillance of antimicrobial resistant bacteria in nosoco...

Background: Enterococci spp. bacteria especially Enterococcus faecalis and E. faecium have the ability to acquire antibiotic-resistance pattern and causing life-threatening hospital-acquired infections. So, the aim of this study was to count and isolate of E. faecalis and E. faecium from milk and dairy desserts consumed in Assiut city, Egypt. Methods: A total of 100 raw milk, ice cream, mehall...

in today's business world, proper identification of customer’s requirements and a quick response to these requirements is a key to commercial success. increasing customer loyalty affects the profitability and organizations can ensure their long-term interests by means of planning. in today's competitive world, the services provided by the competing company have to be more similar to e...

Background and Aims: Rhnull, with an estimated incidence of one per 6,000,000 individuals, is an extremely rare disorder with an autosomal recessive pattern of inheritance that is more common in societies with a high rate of consanguinity. Materials and Methods: In this study, we report the first case with Rhnull, a blood group phenotype in southeast Iran, which was diagnosed during pretransf...

Mass and charge identification of charged products detected with Silicon-CsI(Tl) telescopes of the Chimera apparatus is presented. An identification function, based on the Bethe-Bloch formula, is used to fit empirical correlation between ∆E and E ADC readings, in order to determine, event by event, the atomic and mass numbers of the detected charged reaction products prior to energy calibration.
