    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.

    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.
