Aim and Background: Meticillin resistant Staphylococcus aureus (MRSA) has become one of the major public-health concerns in recent years due to resistance to antimicrobial drugs and agents. This Study aims to diagnose of MRSA isolates by molecular and phenotypic methods and to detect of the antibiotic resistance pattern in MRSA strains in clinical patient samples in Rasht. Material and Methods...
Present methods for genetic evaluation of livestock are largely based on phenotypic information and pedigree registration. Genomics offers the opportunity to dissect phenotypic differences at the molecular level, which provides a better insight into the underlying genetic model. This affects genetic evaluations as well as selection strategies. Opportunities to utilize molecular and phenotypic i...
Background and Objectives: Traditionally, diagnosis of the agents of infectious diseases is based on conventional or phenotypic methods. Due to the lack of growth of some infectious agents, these methods are very difficult or impossible for diagnosis of some bacteria. The advent of molecular techniques has more or less influences on the detection of microbial infections. This article addresses ...
background one of the major clinical problems regarding pseudomonas aeruginosa is attributed to metallo-beta-lactamases (mbl). this group of enzymes is a subset of beta lactamases which belong to group b of ambler classification and cause hydrolysis of carbapenems. based on epidemiological studies conducted worldwide, it is proved that prevalence of genes coding mbls in p. aeruginosa species ar...
in this study, the number of 1802 longevity records of ewes collected during 1989 to 2010 in breeding station of lori-bakhtiari sheep flocks were used to estimate of genetic, environmental and phenotypic trends for economic lifetime. the breeding values of a ewe’s lifetime were estimated by restricted maximum likelihood procedure under an animal model of univariate analysis. the best linear unb...
In this research, investigation of genetic, phenotypic and environmental trends of biometric traits in Makuie sheep was performed using collected data from 1989 to 2012 at Makouei sheep breeding station. Estimation of trends was performed by multivariate animal model using the DFREML software. Genetic, phenotypic and environmental trends were estimated by regression of breeding values average, ...
ABSTRACT Background and Objective: Escherichia coli is one of the most common causes of hospital-acquired infections. Extended-spectrum β-lactamase (ESBL)-producing E. coli strains are resistant to third-generation cephalosporins. The three main genes involved in ESBL production are TEM, SHV and CTX-M. Detection of ESBL-producing E. coli is of importan...
Background Antibiotic resistance is a major health problem, as drugs that were once highly effective no longer cure bacterial infections. WGS has previously been shown to be an alternative method for detecting horizontally acquired antimicrobial resistance genes. However, suitable bioinformatics methods that can provide easily interpretable, accurate and fast results for antimicrobial resistanc...
The accuracy of matrix-assisted laser desorption-ionization time of flight mass spectrometry (MALDI-TOF MS) in the identification of Haemophilus, Aggregatibacter, Cardiobacterium, Eikenella, and Kingella (HACEK) species was compared to that of phenotypic methods (Remel RapID and Vitek 2). Overall, Vitek MS correctly identified more isolates, incorrectly identified fewer isolates, and failed to ...
