    Prevalence, Virulence Characterization, and Genetic Relatedness of Listeria Monocytogenes Isolated From Chicken Retail Points and Poultry Slaughterhouses in Turkey
    (Springer, 2019) Çoban, Ayşen; Pennone, Vincenzo; Sudağıdan, Mert; Molva, Çelenk; Jordan, Kieran; Aydın, Ali
    Listeria monocytogenes is one of the most important foodborne pathogens and is a causal agent of listeriosis in humans and animals. The aim of this study was to determine the prevalence, serogroups, antibiotic susceptibility, virulence factor genes, and genetic relatedness of L. monocytogenes strains isolated from 500 poultry samples in Turkey. The isolation sources of 103 L. monocytogenes strains were retail markets (n = 100) and slaughterhouses (n = 3). L. monocytogenes strains were identified as serogroups 1/2a-3a (75.7%, lineage I), 1/2c-3c (14.56%, lineage I), 1/2b-3b-7 (5.82%, lineage II), 4a-4c (2.91%, lineage III), and 4b-4d-4e (0.97%, lineage III). Most of the L. monocytogenes strains (93.2%) were susceptible to the antibiotics tested. PCR analysis indicated that the majority of the strains (95% to 100%) contained most of the virulence genes (hylA, plcA, plcB, prfA, mpl, actA, dltA, fri, flaA inlA, inlC, and inlJ). Pulsed-field gel electrophoresis (PFGE) demonstrated that there were 18 pulsotypes grouped at a similarity of >90% among the strains. These results indicate that it is necessary to prevent the presence of L. monocytogenes in the poultry-processing environments to help prevent outbreaks of listeriosis and protect public health.

    Prevalence and Diversity of Arcobacter Spp. in Retail Chicken Meat in Turkey
    (PagePress Publications, 2016) Molva, Çelenk; Atabay, Halil İbrahim
    Arcobacters are food and waterborne pathogens associated with human and animal infections. The objective of the present study was to investigate the prevalence and diversity of Arcobacter spp. in commercially sold chicken meat in Izmir region of Turkey. For this purpose, 100 samples including legs (n= 40), 17 chicken quarters (n= 17), drumstickers (n= 16), breasts (n= 11), wings (n= 10), and carcasses (n= 6) were collected from different retail markets. A total of 65 isolates were confirmed as Arcobacter spp. from 55 samples by genus-specific polymerase chain reaction (PCR). The prevalence of Arcobacter spp. was 32.5, 81.3, 64.7, 72.7, 83.3, and 50% for legs, drumstickers, chicken quarters, breasts, carcasses and wings, respectively. Based on the multiplex-PCR, most of the isolates were identified as A. butzleri (n= 45, 80%), followed by A. cryaerophilus (n= 2, 3.6%), A. skirrowii (n= 1, 1.8%) and 17 isolates (30.9%) could not be identified at the species level.
