| presence of drug resistance in intestinal lactobacilli of dairy and human origin in turkey. | the prevalence of different resistance genes was investigated in lactobacilli of human and dairy origin by pcr. the presence of erm, van, tet, and cat-tc genes were determined in 16 raw milk, 15 cream, 10 yogurt, 50 hand-made cheese, and 20 industrially produced white-cheese samples of dairy origin and 16 mouth, 32 fecal, and 36 vaginal samples from different subjects of human origin. lactobacilli of dairy and human origin were found to carry only erm(b) and tet(m) genes. the majority of the iso ... | 2004 | 15212784 |
| comparative structural and functional studies of avian and mammalian hemoglobins. | thermal stabilities of chicken, grey lag goose (anser anser), turkey as avian hemoglobins (hbs); and human, bovine, sheep and horse as mammalian hbs in hemolysate form were investigated and compared with oxygen affinities taken from literature. the thermal stability was obtained from thermal profiles using temperature scanning spectrophotometry. the buffer conditions were 50 mm tris, ph 7.2, and 1 mm edta. the average of the inverse temperature transitions, average hydrophobicity, total van der ... | 2002 | 12362988 |
| cutaneous anthrax in eastern turkey. | anthrax, caused by the spore-forming bacterium bacillus anthracis, is rarely seen in industrial nations but is common in developing countries. cutaneous anthrax (ca), the most common form of the disease, accounts for 95% of cases and usually develops on exposed sites. this study reviews the clinical and laboratory findings of 21 patients diagnosed with ca during 2 separate epidemics in the van region of turkey. all patients had a history of direct contact with infected cattle. the patients, aged ... | 2001 | 11419020 |
| selenium content of milk and milk products of turkey. ii. | selenium content of 1028 milk and milk products of turkey are presented in this study. the selenium content of human milk (colostrum, transitional, and mature milk), various kinds of milk [cow, sheep, goat, buffalo, paper boxes (3%, 1.5%, 0.012% fat), bottled milk, condensed milk (10% fat), mineral added milk (1.6%), and banana, strawberry, and chocolate milk] and milk products (kefir, yogurt, ayran, various cheese, coffee cream, ice cream, butter, margarine, milk powder, and fruit yogurt) in tu ... | 1999 | 10208658 |
| characterization of bovine and human group b streptococci isolated in turkey. | in the study, group b streptococci (gbs) isolated from bovines and humans in and around van, eastern turkey, were serotyped, and their haemagglutination and lectin-agglutination properties were also determined. this study is the first epidemiological survey of gbs serotypes performed in turkey. a total of 148 gbs isolates, 76 from bovine milk and 72 from women attending a maternity polyclinic, were examined by co-agglutination, slide haemagglutination and slide lectin-agglutination tests. by the ... | 2006 | 16585637 |
| a serological investigation of pestiviruses in sheep in eastern border of turkey. | all pestiviruses are important veterinary pathogens causing economic losses in cattle, sheep, and pigs. in this study, blood samples randomly collected from 465 sheep were analysed for the presence of antibodies to pestiviruses (bovine viral diarrhea virus, border disease virus) using an enzyme-linked immunosorbent assay in the province of van and their towns. the seroprevalance were estimated as 75.9% and 60.0-82.5% in the sampled animals and sampled towns, respectively. the results revealed th ... | 2011 | 21461731 |
| calculations of the binding affinities of protein-protein complexes with the fast multipole method. | in this paper, we used a coarse-grained model at the residue level to calculate the binding free energies of three protein-protein complexes. general formulations to calculate the electrostatic binding free energy and the van der waals free energy are presented by solving linearized poisson-boltzmann equations using the boundary element method in combination with the fast multipole method. the residue level model with the fast multipole method allows us to efficiently investigate how the mutatio ... | 2010 | 20831336 |
| prevalence of eimeria spp., cryptosporidium spp. and giardia spp. in calves in the van province. | this research was carried out in order to determine the prevalence of eimeria spp. cryptosporidium spp. oocysts and giardia cysts in calves less than 6 months of age in van province. for this purpose, fecal samples were obtained from the rectum of 182 calves. fecal samples (n: 182) were examined with the modified acid-fast technique for cryptosporidium spp. oocysts. the same samples were examined by zinc sulphate flotation technique for eimeria oocysts and giardia cysts. during the laboratory ex ... | 2008 | 18985571 |
| molecular genetic characterization of different isolates of echinococcus granulosus in east and southeast regions of turkey. | we used pcr-rflp analysis of ribosomal its1 fragment using four different restriction enzymes and dna sequencing of mitochondrial co1 gene to investigate the genetic characteristics of isolates of echinococcus granulosus obtained from different hosts (179 sheep, 19 cattle, 7 goat, 1 camel, 1 dog and 1 human) and regions (elazig, malatya, erzurum, van, diyarbakir and sanliurfa) of turkey. the report represents the most comprehensive genotypic investigation of e. granulosus isolates undertaken in ... | 2008 | 18579101 |
| classical enterotoxigenic characteristics of staphylococcus aureus strains isolated from bovine subclinical mastitis in van, turkey. | the aim of the present study was to investigate classical enterotoxigenic properties of staphylococcus aureus strains isolated from cows with subclinical mastitis. for this purpose, 480 milk samples from cows with subclinical mastitis raised in different villages neighbouring van city center were collected. a total of 106 s. aureus strains were isolated. twenty seven isolates (25.5%) were found to be enterotoxigenic by reverse passive latex agglutination (rpla). of these, 25 (23.6%) were positiv ... | 2008 | 18485509 |
