Salmonella spp. represent one of the most common causes of bacterial foodborne illnesses around the world. The species Salmonella enterica contains more than 2500 serotypes, and emergence of new human pathogenic Salmonella strains and serotypes represents a major public health issue. Salmonella enterica subsp. enterica serotype 4,5,12:i:- represents a monophasic variant of Salmonella Typhimurium, which has rarely been identified before the mid-1990s. The prevalence of this serotype among human salmonellosis cases has increased considerably since the mid-1990s and Salmonella 4,5,12:i:- currently (i. e., the first decade of the 2000s) represents one of the most common serotypes among human cases in many countries around the world. This paper discusses our current knowledge of the global ecology, epidemiology, transmission, and evolution of this emerging Salmonella serotype.


Molecular evaluation and antimicrobial susceptibility testing of Escherichia coli isolates from food products in Turkey
Kyere, Emmanuel Owusu; Bulut, Ece; AVŞAROĞLU ERKAN, MÜRŞİDE DİLEK; Soyer, Yeşim (Springer Science and Business Media LLC, 2015-06-01)
Some strains of Escherichia coli can be important food borne pathogens. Characterization and antimicrobial resistance testing of 28 E. coli isolates from random food samples obtained in Van, Turkey were performed. Primers for 6 indicator genes (fliC, stx1, stx2, eae, hlyA, and rfbE) for shiga toxin-producing E. coli and 5 indicator genes for each pathogroup (bfpA, aggR, ipaH, daaD, st, and lt) were used. E. coli isolates were also typed using pulsed field gel electrophoresis with the XbaI restriction enzyme...

Salmonella is commonly found in a variety of food products and is a major cause of bacterial foodborne illness throughout the world. In this study, we investigated the prevalence and diversity of Salmonella in eight different food types: sheep ground meat, cow ground meat, chicken meat, cow offal, traditional Sanliurfa cheese, unripened feta cheese, pistachios, and isot (a spice blend of dried red peppers specific to Sanliurfa), traditionally and commonly consumed in Turkey. Among 192 food samples, Salmonel...
Differentiation of Salmonella Typhimurium from Salmonella Enteritidis and other Salmonella serotypes using random amplified polymorphic DNA analysis
Gültekin, Güzin Candan; Ogel, Z. B.; Oren, N. G. (Elsevier BV, 2008-06-01)
Salmonella enterica ssp. enterica serovar Typhimurium and Salmonella enterica ssp. enterica serovar Enteritidis are the major dominating serotypes of Salmonella in poultry and poultry products. Infection by Salmonella Typhimurium is an important cause of morbidity and mortality in poultry. Rapid differentiation of Salmonella Typhimurium from other Salmonella serotypes including Salmonella Enteritidis can be very crutial for public health and for epidemiologists and for the poultry industry. Ten arbitrarily ...
Interactions of high hydrostatic pressure, pressurization temperature and pH on death and injury of pressure-resistant and pressure-sensitive strains of foodborne pathogens
Alpas, Hami; BOZOGLU, F; RAY, B (Elsevier BV, 2000-09-15)
The objective of this: study is to determine the interactions between high hydrostatic pressure, pressurization temperature, time and pH during pressurization on death and injury of pressure-resistant and pressure-sensitive strains of four foodborne pathogens: Staphylococcus aureus 485 and 765, Listeria monocytogenes CA and OH2, Escherichia coli O157:H7 933 and 931, Salmonella enteritidis FDA and Salmonella typhimurium E21274. Among these strains S. aureus 485, L. monocytogenes CA, E, coli O157:H7 933 and S...
Killer toxin of Pichia anomala NCYC 432; purification, characterization and its exo-beta-1,3-glucanase activity
Izgu, Fatih; Altinbay, Demet; Acun, Tolga (Elsevier BV, 2006-08-02)
Pichia anomala NCYC 432 secretes a killer toxin which is inhibitory to a variety of yeasts including pathogenic Candida spp. The killer toxin in the culture supernatant was concentrated by ultratiltration and purified to homogenity by two successive gel filtration chromatographies with a TSK G2000SW column. Biochemical characterization of the toxin showed that it is a glycosylated protein with a molecular mass of 47 kDa and pI values of 3.4 and 3.7. The toxin showed high stability at pH values between 3 and...
