Region X of the protein A gene (spa) was sequenced from methicillin-resistant Staphylococcus aureus (MRSA) isolates originating animals, humans and environment at veterinary hospitals in UK Ireland. MRSA transmission between animals staff assessed on basis spa typing, PFGE epidemiological data.MRSA dogs (n = 27), horses 9), cats 6), 22) environmental surfaces 3) were analysed by typing. Known contacts human animal carriers ascertained hospitals.All feline, most canine (96%) (82%) showed...
Antimicrobial stewardship guidelines (ASGs) represent an important tool to help veterinarians optimize their antimicrobial use with the objective of decreasing resistance. The aim this study was map and qualitatively assess ASGs for in cats dogs Europe. Country representatives European Network Optimization Veterinary Treatment (ENOVAT) were asked identify published countries. All collated updated since January 2010 containing recommendations on therapy at least three conditions affecting...
The blaZ gene encoding penicillin resistance can be located either chromosomally or on plasmids. aim of this study was to investigate the genetic relationships and determine location in S. aureus isolated bovine mastitis Finland Sweden.Seventy-eight β-lactamase positive isolates from (34 44 Sweden) were included study. localization determined by Southern blotting. genes sequenced sequences translated beta-lactamase proteins further grouped as different protein signatures. and, control, 33...
Rectal swabs from 100 dogs that were admitted to the veterinary clinic and randomly selected one kennel examined for presence of Salmonella spp. S. Enteritidis was isolated a household dog strain susceptible all antibiotics tested. Typhimurium it sensitive except streptomycin neomycin. Even though, occurence in feces this study low, attention should always be given when handling canine or contaminated materials.
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,...
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)...
Abstract The NH‐, NH‐,S‐ substituted‐1,4‐naphthoquinones and S‐ substituted‐1,4‐benzoquinones have been synthesized from the reaction between quinones (2,3‐Dibromo‐1,4‐naphthoquinone or p ‐benzoquinone) different amines. structures of compounds confirmed using FTIR, UV‐Vis, 1 H‐NMR, 13 C‐NMR, mass MS(ESI) spectrometry cyclic voltammetry (CV). ground state energies molecules estimated B3LYP functional with basis sets based on time dependent density theory (TD‐DFT). theoretical ΔE gap values...
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...
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)...
Abstract This study is aimed to investigate culturable airborne bacteria concentrations and the composition of methicillin-resistant staphylococci in eleven different locations on basis specific activities conducted within parts European side Istanbul. The highest bacterial levels were observed at Bakirkoy station (1 100 CFU/m 3 ) while second found Bahcelievler 040 October; lowest (10 measured other stations (Atakoy, Yesilkoy). Fifteen isolates [ Staphylococcus hominis (n=11), S. cohnii...
Fomites such as brushes and clippers are known to be potential risk factors for the transmission of dermatophytes between pet animals. The aim this study was investigate by examining those grooming implements presence any viable dermatophytes.For purpose, samples from 235 pieces equipment swab surface 14 tables were taken 41 veterinary clinics 3 salons.Trichophyton tonsurans isolated two clipper blades one clinic Microsporum canis three toothbrush another clinic.This shows that current...
Antimicrobial stewardship initiatives are widely regarded as a cornerstone for ameliorating the global health impact of antimicrobial resistance. Within companion animal health, such efforts have largely focused on development and dissemination guidelines (ASGs). However, there been few attempts to understand veterinarian attitudes towards knowledge ASGs or determine how awareness regarding might best be increased. An online survey was formulated veterinarians who treat animals. The...
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...

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...
