Vancomycin-variable enterococci in sheep and cattle isolates and whole-genome sequencing analysis of isolates harboring and genes.

Background: Vancomycin resistance encoded by the // genes in enterococci is clinically important because of the transmission of these genes between bacteria. While vancomycin resistance is determined by detecting only and genes by routine analyses, failure to detect resistance causes vancomycin resistance to be overlooked, and clinically appropriate treatment cannot be provided.

Aims: The study aimed to examine the presence of -positive enterococcal isolates in Ankara, Turkey, and to have detailed information about them with sequence analyses.

Campylobacter anatolicus sp. nov., a novel member of the genus Campylobacter isolated from feces of Anatolian Ground Squirrel (Spermophilus xanthoprymnus) in Turkey.

Seventy-four Gram-negative, motile, slightly curved rod-shaped, microaerophilic, oxidase-positive and catalase-negative isolates, recovered from fecal samples of the Anatolian ground squirrel (Spermophilus xanthoprymnus) in Kayseri, Turkey, were subjected to a polyphasic taxonomic study. Results of a genus-specific PCR indicated that all isolates belonged to the genus Campylobacter. 16S rRNA gene sequence analyses revealed the closest match as Campylobacter curvus DSM 6644 with identity levels of 96.

Plasmid-Mediated Colistin Resistance in O157:H7 Cattle and Sheep Isolates and Whole-Genome Sequence of a Colistin-Resistant Sorbitol Fermentative O157:H7.

The aims of this study were to investigate the plasmid-mediated colistin resistance genes (, , , , and ), phenotypic colistin resistance in O157:H7/H7 strains isolated from cattle and sheep, and whole-genome sequence (WGS) analysis of colistin-resistant sorbitol fermentative O157:H7. According to the results, 5 of the 49 isolates were found to harbor and/or genes. Three isolates, including a sorbitol fermentative O157:H7, were found phenotypically resistant to colistin with a minimum inhibitory concentration value of 128 μg/mL.

Prevalence and Characterization of Listeria monocytogenes Isolated from Beef and Sheep Carcasses in Turkey with Characterization of Locally Isolated Listeriophages as a Control Measure.

Swab samples from cattle and sheep carcasses (120 of each) were tested for Listeria monocytogenes, and 120 slaughterhouse wastewater samples were tested for listeriophages over 12 months (10 samples per month) to note the seasonal distribution. L. monocytogenes and bacteriophage isolates were characterized, and the biocontrol of L.

Serotype distribution of Salmonella isolates from turkey ground meat and meat parts.

The aim of the study was to find out the serotype distribution of 169 Salmonella colonies recovered from 112 Salmonella positive ground turkey (115 colonies) and 52 turkey meat parts (54 colonies). Out of 15 Salmonella serotypes: S. Corvallis, S.

Molecular typing of Clostridium perfringens isolated from turkey meat by multiplex PCR.

Aims: To determine the presence of toxin genes in 22 Clostridium perfringens isolated from turkey meat samples by molecular typing.

Methods And Results: For this purpose, alpha (cpa), beta (cpb), beta 2 (cpb2), epsilon (etx), iota (iA) and enterotoxin (cpe) toxin genes were analysed by multiplex PCR. All 22 turkey meat Cl.

Structural Evolution of the Tuzgölü Basin in Central Anatolia, Turkey.

The Central Anatolian segment of the Alpine-Himalayan orogen contains "interior" basins, the largest of which is the Tuzgölü (Salt Lake) basin (>20,000 km2). It is bounded on the east by the Tuzgölü (Salt Lake) fault zone and on the west by the Yeniceoba and Cihanbeyli fault zones. Structural, stratigraphic, and sedimentologic evidence suggests that the Tuzgölü basin started as a fault-controlled basin during late Maastrichtian tectonism when the present-day northwest-trending faults that bound the basin were initiated.
