Listeria monocytogenes in food: Control by monitoring the food processing environment
Listeria monocytogenes is a foodborne pathogen that is widely dispersed in the environment; it is found in soil, water and plant material, and can grow at refrigeration temperature and at unfavourable conditions of pH (up to pH 4.7) and salt (up to 10%). It can persist in the harsh conditions of the food processing environment from which it can contaminate food. Listeriosis, infection with L. monocytogenes, can be mild...
Safety characterization of Yersinia enterocolitica strains isolated from raw milk in Western Algeria
Yersinia enterocolitica, an important food-borne enteric pathogen is associated with various clinical manifestations ranging from self-limited gastroenteritis to more invasive syndrome such as terminal ileitis and mesenteric lymphadenitis. The main aim of this study was to investigate the incidence of Y. enterocolitica in milk samples. For this purpose, one hundred (100) samples of raw cow’s milk were collected...
Isolation, characterization, and properties study of probiotic lactic acid bacteria of selected yoghurt from Bangladesh
Probiotics, as functional food components, are recognized as safe microorganisms of viable single or mixed cultures with claimed health promoting effects on their host by improving the properties of the indigenous intestinal microflora. In the present study, a total of ten probiotic lactic acid bacteria were isolated comprising Lactobacillus acidophilus, Lactobacillus brevis, Bifidobacterium sp. and Streptococcus...
Phenotypic and genotypic methods for detection of metallo beta lactamases among carbapenem resistant Enterobacteriaceae clinical isolates in Alexandria Main University Hospital
Dissemination of carbapenem resistant Enterobacteriaceae (CRE) poses a considerable threat to public health. The aim of the present work was to estimate the prevalence of metallo beta lactamases (MBL) among CRE isolated from Alexandria Main University Hospital, Egypt, to evaluate the performance of different phenotypic methods for the detection of MBL, and to investigate the local antimicrobial sensitivity profile of...
Molecular detection of resistance to rifampicin and isoniazid in tuberculosis patients in Senegal
The aim of this study was to use molecular methods to determine the profile of resistance to rifampicin (RMP or RIF) and isoniazid (INH) in mycobacteria from tuberculosis patients in Senegal. Sputum samples (48) received by the mycobacterial laboratory of the National Antituberculosis Program (NATP) in Senegal between 2012 and 2014 were studied. Most of these samples came from patients in treatment failure or relapse...
