Thymus sipyleus Boiss. subsp. rosulans (Borbas) Jalas (TS) is a commonly used plant in the treatment of various complaints, including skin wounds Turkish folk medicine. Despite widespread traditional use TS, there not any scientific report confirming effectiveness this on healing process. This research aimed to investigate effects different extracts obtained from TS biological events during wound healing, cellular basis. In context, proliferative activities extracts, as well closure and...
We present CCD UBVRI photometry of the field open cluster NGC 6866. Structural parameters are determined utilizing stellar density profile stars in field. calculate probabilities being physical members cluster, using their astrometric data, and perform further analyses only most probable members. The reddening metallicity were by independent methods. LAMOST spectra ultraviolet excess F- G-type main-sequence indicate that is about solar value. estimated E(B − V) = 0.074 ± 0.050 mag U B versus...
The increase of antimicrobial resistance in companion animals has already been reported worldwide; however, there is a deficiency data and studies focusing on the profiles Escherichia coli isolates from Passeriformes Psittaciformes which regarded to be among most common popular pet/companion bird species. For this reason, current research was aimed evaluate presence E. apparently healthy birds their profiles. Two hundred sixty-five cloacal swab samples collected (116 parakeets, 59 canaries,...
In this study, the presence of Ornithobacterium rhinotracheale infection in avian population Marmara and Western Black Sea region was investigated. Trachea samples were randomly obtained from 96 chickens sent to slaughterhouses. The seroprevalance determined 384 blood sera. Ninety-six these belonged animals which trachea obtained. Eleven (11.46%) O. isolated taken 10 different flocks brought slaughterhouse. Serotype A predominant serotype among 11 isolates rhinotracheale. One isolate could...
Abstract Introduction: The study aimed to isolate thermophilic Campylobacter from chickens raised three rearing methods, determine its antimicrobial susceptibilities, and examine resistance-related genes by PCR. Material Methods: Cloacal swabs or intestinal contents were taken in Istanbul, Sakarya, Izmir provinces. Chickens small village-based family-run businesses (n = 70), organically 71), conventionally broilers 79). samples cultured on modified charcoal cefoperazone desoxycholate (mCCD)...
The purpose of the study was to examine prevalence Escherichia coli in shrimps and mussels, determine distribution β-lactam, aminoglycoside, quinolone, multi-drug resistance phenotypically genotypically E. isolates obtained from mussels Istanbul. Faecal samples were collected (n = 96) Marmara Sea coastline fish markets For detection antibiotic susceptibilities, seven groups used. β-lactamase, quinolone genes also determined. A total 34 (17.7%, 15 shrimps, 19 mussels) isolated, 17 (50%) found...
This study, for the first time in Turkey, investigated existence of Chlamydophila psittaci and determined prevalence its disease, chlamydiosis, pet birds. Polymerase chain reaction (PCR) was compared with other testing methods that have been typically used diagnosis C. psittaci. Fecal specimens (n = 96) avian origin were tested by PCR two identification methods, modified Gimenez staining (mGS) direct fluorescein–conjugated monoclonal antibody (FA). The implemented yolk sacs embryonated...
2-Methoxy-6-(5-H/methyl/chloro/nitro-1H-benzimidazol-2-yl)phenols (HLx; x = 1-4, respectively) ligands and HL1 complexes with Fe(NO3)3, Cu(NO3)2, AgNO3 Zn(NO3)2 were synthesized characterized. The structures of the compounds confirmed based on elemental analysis, molar conductivity, magnetic moment, FT-IR, 1H- 13C-NMR. antibacterial activity minimum inhibitory concentration (MIC) free ligands, their hydrochloride salts evaluated using disk diffusion method in dimethyl sulfoxide (DMSO)...
Rhodococcus equi has been recognized as an equine pathogen since 1923 and is a worldwide in foals. Up to now, there one report on R. infection Arabian foal Turkey. We here two cases of pneumonia diagnosed Turkish was isolated from pure cultures obtained lung abscesses dead foals which were sent the laboratory distinct stud-farms Izmit district, Turkey, due increasing mortality with pneumonia. These isolates analyzed by plasmid protein profiles: isolate had 85-kb type I virulence other...
This study explored the effects of a single administration flunixin meglumine (acting as non-steroidal anti-inflammatory drug) and oxytetracycline combination on reproductive performance cows diagnosed with subclinical endometritis during postpartum period. Cows aged 3 to 9 at 40 60 days were studied. Endometrial samples collected from that had uterine cornu (middle cornu) width greater than 3.5 cm in ultrasonographic examination, included study. group 1 (n = 20) received dose 20 mg 300 IM...
The present research was aimed to determine the prevalence of dermatophytes isolated from symptomatic dogs and cats, within a 15-year-period, in city Istanbul, Turkey. Dermatological specimens were collected 1504 846 which presented clinical signs ringworm. Direct microscopy mycological cultures performed. fungal growth rate detected at 8.2% 22.8% respectively. Microsporum canis most frequently species followed by Trichophyton spp., M. gypseum , T. mentagrophytes nanum other spp. moreover...
The palatine tonsils of 220 pigs were examined for the occurrence Streptococcus suis and other species. Samples cultured onto Colombia agar plates with 5% defibrinated horse blood selective antibiotic supplement incubated at 37 °C 24-48 h aerobically. Presumptive colonies identified using API20 Strep (bioMérieux). S. was not detected in any examined. porcinus most common streptococcus recovered isolated from 68 (31%) pigs. From samples, agalactiae 19 (8.6%), equi subsp. zooepidemicus 10...
This study was designed to investigate in vitro biological activities and phytochemical composition of aqueous ethanolic extracts from Achillea sintenisii Hub- Mor. (AS). To determine the chemical AS extracts, analyses were performed by using HPLC–ESI-Q-TOF-MS-MS. Afterwards, both investigated terms their effect on fibroblast proliferation, collagen synthesis, hydrogen peroxide-induced damage. In addition cell culture analysis, antibacterial, antioxidant, hyaluronidase inhibitory total...
4-Methoxy-2-(5-H/methyl/chloro/nitro-1H-benzimidazol-2-yl)-phenol(HL_X; X=1-4) ligands and HL_1 complexes with Fe(NO_3)_3, Cu(NO_3)_2, AgNO_3, Zn(NO_3)_2 were synthesized characterized. The structures of the compounds confirmed on basis elemental analysis, molar conductivity, magnetic moment, FT-IR, UV-visible, ^1H- ^{13}C-NMR. Antibacterial activity free ligands, their hydrochloride salts, was evaluated using disk diffusion method in dimethyl sulfoxide (DMSO) as well minimum inhibitory...
Some N-(3,5-di-/1,3,5-trimethylpyrazole-4-yl)-4-substitutedbenzamide derivatives were prepared as possible antiociceptive-antimicrobial agents. New amide (3–12) synthesized by reacting 4-amino-3,5-di and 1,3,5-trimethylpyrazoles with 4-substitutedbenzoyl chlorides. Hotplate tail-immersion tests used for the determination of antinociceptive activity. Morphine, was a standard test drug. All compounds administered at dose 100 mg/kg ip some them had significant activity in both tests. Compound...
The present study was to investigate the incidence of Helicobacter pullorum in caecum and colon 96 broiler chickens.
