Salmonella enterica serovar Heidelberg strains are frequently associated with food-borne illness, with recent isolates showing higher rates of resistance to multiple antimicrobial agents. One hundred eighty S. enterica serovar Heidelberg isolates, collected from turkey-associated production and processing sources, were tested for antimicrobial susceptibility and compared by pulsed-field gel electrophoresis (PFGE) and plasmid profile analysis. The potential for the transfer of resistance between strains was studied by conjugation experiments. PFGE analysis using XbaI digestion identified eight clusters (based on 90% similarity), with the largest containing 71% of the isolates. Forty-two percent of the isolates were resistant to at least 1 of the 15 antimicrobial agents tested, and 4% of the isolates were resistant to 8 or more antimicrobial agents. Resistances to streptomycin (32%), tetracycline (30%), and kanamycin (24%) were most commonly detected. Interestingly, the XbaI PFGE profiles of selective multidrug-resistant strains (n = 22) of S. enterica serovar Heidelberg from turkey-associated sources were indistinguishable from the predominant profile (JF6X01.0022) detected in isolates associated with human infections. These isolates were further differentiated into seven distinct profiles following digestion with the BlnI enzyme, with the largest cluster comprising 15 isolates from veterinary diagnostic and turkey processing environments. Conjugation experiments indicated that resistance to multiple antimicrobial agents was transferable among strains with diverse PFGE profiles.

Fungal biodiversity and mycotoxigenic fungi in cooling-tower water systems in Istanbul, Turkey
This is the first study to assess fungal diversity and mycotoxigenic fungi in open recirculating cooling-tower (CT) water systems (biofilm and water phase). The production capability of mycotoxin from fungal isolates was also examined. The mean fungal count in 21 different water and biofilm samples was determined as 234 CFU/100 mL and 4 CFU/cm2. A total of 32 species were identified by internal transcribed spacer (ITS) sequencing. The most common isolated fungi belonged to the genera Aspergillus and Penicillium,...
Editorial: Talking Turkey
While pondering a title for this month’s Editorial, the phrase Let’s Talk Turkey popped into my head. Perhaps it is the double entendre, as in I will talk to you about our family recipe for turkey and stuffing. But in this case, I’m going with the meaning of talking turkey that is in the Dictionary of American Slang and Colloquial Expressions by Richard A. Spears: “Totalkserious business; totalkfrankly.” So let’s talk frankly about the serious business of organics recycling,...
MODULO used for a major project in Turkey
Product: MODULO.MODULO is a single-use formwork that eliminates rising damp and RADON GAS, that naturally exists in the soil in most parts of the world. Application: filling of foundations and slabs Project: Sheraton Grand Samsun Hotal Modulo was used for the filling of the slabs and foundations of Sheraton Grand Samsun Hotel in Turkey. The hotel is provided with 221 guests rooms and 22 suites. Modulo was used to fill the foundations and the slabs of the multi-storey building, guaranteeing a lightweight...
Grapes Dehydration for Raisins Production in Turkey
Raisins are produced commercially by drying harvested grape berries. In order for a grape berry to dry, water inside the grape must be removed completely from the interior of the cells onto the surface of the grape where the water droplets can evaporate. However, this diffusion process is very difficult because the grape skin contains wax in its cuticle, which prevents the water from passing through. In addition to this, the physical and chemical mechanisms located on the outer layers of the grape are adapted to...
