Öğe Detection of Vibrio spp. in mussels harvested from Marmara sea of Turkey(2006) Ciftcioglu G.; Arun O.O.; Vural A.; Acar M.S.Thirty raw and 30 fried mussel samples were analyzed for the presence of Vibrio spp. twenty two out of 30 raw mussel samples (73.3%) were found contaminated with Vibrio spp. Eight Vibrio vulnificus strains was isolated from 30 raw mussel samples (26.7%). Other Vibrio spp. which were frequently isolated were V. alginolyticus, V. parahaemolyticus, V. cholera and V. mimicus and they were detected at the rate of 36.7%, 20.0%, 6.7% and 3.3% respectively. No Vibrio spp. were detected in fried mussels.Öğe Determination of E. coli O157 in raw and cooked Doner kebabs by using IMS technique(2007) Arun O.O.; Aydin A.; Vural A.; Ciftcioglu G.; Aksu H.Escherichia coli O157 is one of the major threats to public health due to the consumption of meat and meat products. The microorganism is known as a food-borne pathogen even in the presence of low levels. Therefore, a more sensitive method is required to be used for the detection of the microorganism. Immunomagnetic separation (IMS) is a technique used to improve the sensitivity of the detection. IMS has been used to determine the presence of E. coli O157 in raw and cooked Doner samples in this study. 3 out of 30 raw Doner samples have been found to be contaminated with E. coli O157. None of the cooked samples were carrying the agent.Öğe Effect of gamma irradiation on microbiological quality of fermented sausages(2007) Vural A.; Ciftcioglu G.; Aksu H.Turkish fermented sausages are one of the commonly consumed meat products in Turkey. In this study the effects of low dose gamma irradiation (1, 2 and 3 kGy) on the microbiological quality properties of Turkish fermented sausages have been investigated. The numbers of total aerobic mesophilic bacteria, coliform, Staphylococcus aureus, mould, yeast, lactic acid bacteria, and sulphite reducing Clostridia were analyzed. In sausage samples it was determined the number of microorganisms decreased or were eliminated according to the increased doses of gamma irradiation. The dose of 1 kGy was sufficient to eliminate the yeasts and sulphite reducing Clostridia. Coliforms and moulds were reduced to under detectable values after the application of 2 kGy irradiation doses, Staphylococcus aureus and lactic acid bacteria by the application 3 kGy. It was concluded that the 2 kGy dose was sufficient to control bacterial population to maintain Turkish fermented sausages within designated standards for this product.Öğe The examination of the microbiologic quality in Örgü Cheese (Braided Cheese) samples(2010) Vural A.; Erkan M.E.; Güran H.S.In this study, totally 105 Örgü Cheese samples were analyzed in terms of total mesophilic aerob bacteria, coliform bacteria, Escherichia coli, Escherichia coli 0157, Stapyhlococcus-Micrococcus spp., Lactobacillus spp., Lactic streptococcus, mould, yeast, Salmonella spp. and Listeria spp. The contamination rate of coliform bacteria, E. coli, E. coli O157, Staphylococcus-micrococcus spp., mould, yeast, and Listeria spp. were found 80.00%, 65.71%, 7.62%, 84.76%, 32.38%, 93.33%, and 2.86%, respectively. Salmonella spp. could not be determined in any of samples. The resistance to antibiotics of E. coli and E. coli 0157 were also examined. It was concluded that Örgü Cheese may be contaminated with some microorganisms during production or selling. These contaminations also may cause important public health risks.Öğe A histopathological comparison of the effects of demineralized bone-powder and natural coral implants on osteogenesis(1994) Kavak G.; Vural A.; Us H.Demineralized bone powder (DBP) and granular coral (C) implants on the new bone formations were studied using 28 Wistar albino rats were. DBP was applied to prepared bone cavites on the femur in 14 rats and granular C implants were applied in the other 14 rats. The animals were sacrificed at the 3rd and 6th weeks, and the femurs were removed and examined histopathologically. It was observed that the DBP did not induce bone formation within a 3 weeks period but showed highly osteoinductive effect in the 6 weeks period. However the effects of C implants on bone formation both at 3 weeks and 6 weeks periods were much more higher than the DBP.Öğe Physico-chemical and microbiological properties of manna (gezo) samples collected from retailers in south-east of Turkey(Gaurav Publications, 2014) Erkan M.E.; Vural A.; Baran M.S.; Güran H.S.; Durmusoglu H.Manna (gezo) is a traditional sweet, which is commonly consumed in south-east of Turkey. However, there is a myth about the sweet that it is strongly believed by the people within the region that manna is treated as a magical substance that rains down from the sky and it was thought that it could cure some diseases. In this study, totally 30 manna samples were analyzed. The contamination rate of total mesophilic aerob bacteria, coliform bacteria, Bacillus cereus, mold, yeast, osmophilic yeast and sulfite reducing anaerobe bacteria were found 100, 26.66, 23.33, 23.33, 76.66, 96.66 and 36.66%, respectively. Salmonella spp., Listeria spp., Staphylococcus-Micrococcus and Escherichia coli could not be determined in any of the samples. Mean value of pH and moisture, dry matter, ash, protein, fat and crude cellulose of the manna samples were found 5.86, 3.49, 96.51, 13.77, 0.39, 0.79 and 8.99%, respectively. As a result, important pathogens were not determined in the manna samples. However, some indicator bacteria of hygiene such as coliform were detected. It was concluded that during the production of the manna samples might be contaminated with some microorganisms from different sources and these contaminations caused health risks.Öğe Solitary vertebral osteochondromas causing spinal cord compression(1991) Kulah A.; Vural A.; Fiskeci C.Two cases of solitary osteochondroma of the thoracic spine with spinal cord compression are reported. One was a sessile osteochondroma of the lamina and pedicle of T2 vertebra in a 9 year-old child; the other was a pedunculated osteochondroma of the posterior surface of the body of T6 vertebra in a 45 year old man. A discussion of the symptomatology, diagnosis and a review of the related literature are given.Öğe Treatment of chronic cervicitis: The loop electrosurgical excision procedure(1997) Hakverdi A.U.; Gül T.; Taner C.E.; Vural A.; Erden A.C.; Yilmaztürk A.The effectiveness and morbidity of excisional biopsy of cervical tissue using the electrosurgical excision procedure for the treatment of chronic cervicitis was investigated. In this study, loop diathermy was used in the treatment of one hundred patients with chronic cervicitis. Before the procedure, cervical smear and colposcopic examination were done. Then the loop diathermy was performed under local anesthesia. All the removed specimens were evaluated histopathologically. The mean operation time was 6.34 ± 1.37 minutes. The complication of bleeding and secondary infection were 5% and 4%, respectively. All the patients had normal cervical smear (Papanicolaou class I or II). In the microscopic evaluation, thermal damage of the removed specimens were negligible. Six cases (6%) with CIN (CIN I = 4, CIN II = 2) were determined and the others (94%) were reported as chronic cervicitis in the histopathologic examinations of the removed specimens. After the operation, these cases with CIN were followed up for one year with cervical smears and colposcopic examinations. One of the six patients with CIN had recurrence and underwent cold-knife conization. This new technique is simple, quick and cheap. It can be used confidently to provide both diagnosis and treatment with minimal thermal tissue injury in cases with chronic cervicitis.
