    Isolation and Identification of Arcobacter Species From Environmental and Drinking Water Samples
    (Springer Verlag, 2016) Talay, Funda; Molva, Çelenk; Atabay, Halil İbrahim
    Water plays an important role in the transmission of Arcobacter spp. to animals and humans. The aim of this study was to isolate and characterize Arcobacter spp. from 115 different water samples (66 sewage, 25 rivers, 16 spring water, and 8 drinking water) in Izmir, Turkey. In total, 41 samples (35.7 %) were found positive for Arcobacter spp. by the genus-specific PCR. Arcobacter butzleri was detected in 39 out of 115 samples (33.9 %) including 24 sewage, 13 rivers, and 2 spring water. The remaining Arcobacter spp. (n = 2) isolates could not be identified by m-PCR and 16S rRNA gene sequencing. Based on the phenotypic characterization, most of the Arcobacter species (87.8 %) indicated weak catalase activity. In addition, there were differences in phenotypic patterns among isolated species during growth at 37 °C under microaerobic and aerobic conditions, in the presence of 2 % (39/41) and 3.5 % (32/41) NaCl and 0.04 % TTC (39/41) and on MacConkey agar (38/41). The results of this study indicated that environmental water samples are common sources for Arcobacter spp. Therefore, effective control measures should be taken to protect human health.

    Prevalence of Salmonella in Edible Offal in Afyonkarahisar Province, Turkey
    (Kafkas Üniversitesi, 2012) Akkaya, Levent; Atabay, Halil İbrahim; Gök, Veli; Yaman, Hilmi
    In this study, the prevalence of Salmonella sp. was examined using a total of 205 edible bovine offal samples collected from different abattoirs (n=105) and butcheries (n=100) by immunomagnetic separation (IMS) method. The isolation rate of Salmonella was found to be 8.57%, 5.71% and 5.71% for the liver, kidney and tripe samples collected from the abattoir, respectively. Of the offal samples obtained from the butcheries, the detection rate of Salmonella sp. was 16% in the liver and 4% in the kidney, tripe and brain samples. Overall, it was found that 8.29% of all the offal samples obtained from the abattoirs and butcheries were determined to be contaminated with Salmonella sp. The results of this study shows that edible offal are cross-contaminated by Salmonella sp. at the abattoirs and retail sale points until they reach to the consumer. It is recommended that adequate hygienic and sanitary measures be taken in these kind of places in order to protect public health.

    Fourier Transform Infrared Spectroscopy as a Novel Approach for Analyzing the Biochemical Effects of Anionic Surfactants on a Surfactant-Degrading Arcobacter Butzleri Strain
    (SAGE Publications Inc., 2013) Sarıoğlu, Ömer Faruk; Tamer, Yusuf Talha; Özkan, Alper Devrim; Atabay, Halil İbrahim; Molva, Çelenk; Tekinay, Turgay
    Anionic surfactant-biodegrading capability of an Arcobacter butzleri strain was analyzed under aerobic conditions. The A. butzleri isolate displayed efficient surfactant-biodegrading capacity for sodium dodecyl sulfate (SDS) at concentrations of up to 100 mg/L in 6 days, corresponding to 99.0% removal efficiency. Fourier transform infrared spectroscopy was applied to observe the effects of varying concentrations of SDS on the biochemistry of bacterial cells. Results suggest that protein secondary structures were altered in bacterial cells at sufficiently high SDS concentrations, concurrent with SDS biodegradation.

    Isolation of Various Arcobacter Species From Domestic Geese (anser Anser)
    (Elsevier Ltd., 2008) Atabay, Halil İbrahim; Ünver, Ahmet; Şahin, Mitat; Otlu, Salih; Elmalı, Mehmet; Yaman, Hilmi
    In this study, the prevalence and distribution of various Arcobacter spp. were investigated in samples taken from the cloacae of healthy domestic geese raised in Turkey. A membrane filtration technique with a non-selective blood agar was employed after enrichment in Arcobacter enrichment broth (AEB) to isolate a wide range of Arcobacter spp. In addition, the isolates were characterized phenotypically and identified at species level using a multiplex-PCR assay. A total of 90 cloacal swab samples taken from geese, collected on three farms (18, 25, 47 samples, respectively), were examined. Of the samples examined, 16 (18%) were found positive for Arcobacter. One Arcobacter species was isolated from each bird. Of the 16 Arcobacter isolates, 7 (44%), 7 (44%) and 2 (12.5%) were identified by m-PCR as A. cryaerophilus, A. skirrowii and A. butzleri, respectively. The present study indicates that domestic geese can harbour a variety of Arcobacter spp. in their cloacae. The presence of Arcobacter in geese may be of significance as reservoirs in their dissemination. Detailed research is needed for better understanding of the epidemiology and zoonotic potential of this emerging pathogen.
