    Isolation, genotyping and antimicrobial susceptibility of pathogenic Escherichia coli serotypes in ready to eat foods
    (HELLENIC VETERINARY MEDICAL SOC, 2019) Karadal, F.; Onmaz, N. Ertas; Hizlisoy, H.; Al, S.; Telli, N.; Yildirim, Y.; Gonulalan, Z.
    In this study, pathogenic Escherichia coli serotypes (E. coli O157:H7, O26, O111) and their molecular proximity and antimicrobial susceptibility were investigated in RTE foods. A total of 240 samples; consist of 105 stuffed mussel, 56 meatless cig kofte, 54 Russian salad, 25 cheese halva, were analyzed. The conventional culture and serotyping methods for determination of the organisms were performed and further confirmation by PCR was carried out. Confirmed E. coli O157 isolates were genotyped by the enterobacterial repetitive intergenic consensus (ERIC)-PCR. Antibacterial susceptibility testing of the isolates was performed by disc diffusion method. E. coli was detected in 7 (2.9 %) of 240 samples, including 3 (5.5%) Russian salad, 3 (2.8%) stuffed mussel, 1 (4 %) cheese halva. Two isolates from Russian salad, 1 from stuffed mussel and 1 from cheese halva were identified as E. coli O157. In addition, stuffed mussel isolate was found to carry stx1 ve hlyA genes whereas one Russian salad isolate carried the stx1 gene. E. coli isolates were found to be resistant to amoxycillin/clavulonic acid, gentamicin and ciprofloxacin, at the rate of 29%, 14% and 29 %, respectively. Only one (14 %) isolate from stuffed mussel was classified as multidrug resistant to three antimicrobials. Furthermore, the isolates, related to O157 and O157:H7, presented different ribotypes in this study. The results provide useful data for the development of public health policy concerning the potential presence of pathogenic antimicrobial resistant E. coli serotypes in RTE foods. Strict surveillance of RTE foods at retail points for emerging pathogens, their antimicrobial resistance patterns and the potential likelihood of cross-contamination is required.

    Treatment of Bovine papillomavirus-induced teat warts in a cow by using Podophyllin magistral formula and autologous vaccine applications together
    (AGRICULTURAL RESEARCH COMMUNICATION CENTRE, 2019) Kale, M.; Saltik, H. S.; Hasircioglu, S.; Yildirim, Y.; Yavru, S.; Mamak, N.; Atli, K.
    In this study, a 32-month-old Holstein cow that had a calving and common Bovine papillomavirus (BPV)-induced wart on its teats was treated. For this purpose, BPV antigen presence in blood serum sample from the animal was studied by ELISA and was revealed as positive. Magistral drug containing podophyllin active substance was applied topically on teat warts of the animal Applications were performed for all teat warts once in three days during 27 days. Eight hours after applying the drug, teats were washed with sterile water. Warts on teat were proved to have regressed and dried out on the day 27th. The same animal was given papilloma autologous vaccine prepared from warts coming off from the teat on the day 28th. As a result of the vaccination, teats showed full recovery from warts. Finally, it is recommended that using podophyllin formulations topical and autologous vaccine applications together in treating teat warts caused by BPV.
