Salmonella enterica serotype Heidelberg (S. Heidelberg) is frequently implicated in human foodborne Salmonella infections and often produces more severe clinical disease than other serotypes. Livestock and poultry products represent a potential risk for transmission to humans. The purpose of this study was to evaluate 49 S. Heidelberg veterinary isolates for exponential growth rate (EGR), PFGE ...

INTRODUCTION The diagnosis of Marfan syndrome (MFS) depends on a multidisciplinary clinical evaluation. Molecular study to identify mutations in the FBN1 gene can establish a definitive diagnosis even with atypical or «incomplete» phenotypes and enable earlier diagnosis in asymptomatic patients. OBJECTIVES The aim of the present work was to evaluate the frequency and type of FBN1 gene mutatio...

500 Background: Triple negative breast cancer (TNBC) is associated with a higher risk of recurrence and earlier recurrences than other breast cancer phenotypes. We evaluated the genotypic features of TNBC compared with hormone receptor (HR)-positive disease, and also evaluated genotypic features associated with recurrence. METHODS RNA extracted from tumor samples obtained from 764 patients wi...

Lactobacilli are well reckoned for their technological and probiotic significance and their exercise in dairy products for trade and industry. The present study was carried out to isolate and characterize Lactobacilli from various dairy and non dairy sources of Indian origin. The isolates were subjected to phenotypic and genotypic characterizations followed by partial 16S rDNAsequencing . As ma...

Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without ...

INTRODUCTION Rhodococcus equi is an opportunistic pathogen, causing rhodococcosis, a condition that can be confused with tuberculosis. Often, without identifying M. tuberculosis, physicians initiate empiric treatment for tuberculosis. R. equi and M. tuberculosis have different susceptibility to drugs. Identification of R. equi is based on a variety of phenotypic, chromatographic, and genotypic ...

OBJECTIVES Vibrio vunificus is known to cause septicemia and severe wound infections in patients with chronic liver diseases or an immuno-compromised condition. We carried out the molecular characterization of V. vulnificus isolates from human Vibrio septicemia cases based on pulsed-field gel electrophoresis (PFGE) using NotI and SfiI. METHODS AND RESULTS PFGE was used to characterize a total...

Newcastle disease virus (NDV) is an avian paramyxovirus that causes significant economic losses to the poultry industry in most parts of the world. The susceptibility of a wide variety of avian species coupled with synanthropic bird reservoirs has contributed to the vast genomic diversity of this virus as well as diagnostic failures. Since the first panzootic in 1926, Newcastle disease (ND) bec...

Geobacillus stearothermophilus is the main thermophilic spore former involved in flat sour spoilage of canned foods. Three typing methods were tested and applied to differentiate strains at intra-species level: panC sequence analysis, REP-PCR and M13-PCR. panC gene was highly conserved within the studied strains, suggesting a low intra-specific diversity. This was supported by REP-PCR primary a...

Abstract Background Carbapenem-resistant Gram-negative organisms (CRGNO) are a growing threat. We aimed in our study to determine the genotype of carbapenemases at Beni-Suef University Hospital by using newly introduced lateral flow assays comparison with molecular techniques and test effectiveness ceftazidime/avibactam against them. Methods Screening for carbapenemase production was done mSupe...
