■每年在小宠物(猫和狗)的治疗中使用越来越多的药物,包括用于人类治疗的药物(头孢菌素和氟喹诺酮类药物)。
■本研究的目的是分离和探索机会性肠杆菌科(大肠杆菌,克雷伯菌属,Proteus,Ci-trobacter,肠杆菌)来自猫和狗,并在微生物中分离抗性基因。
■2021年,在Kostanay的兽医诊所收集了来自小型家畜的808种生物材料样品。从这些,分离并鉴定了210种微生物。
■所取样的菌株大部分属于E.coli-149(70.9%),肠杆菌11(5.2%),克雷伯菌28(13.3%),变形杆菌-12(5.7%)和10种柠檬酸杆菌(4.8%)。在所有确定的分离株中,抗生素耐药性/敏感性通过圆盘扩散法测定氨苄青霉素,头孢西丁,庆大霉素,左旋霉素,四环素,环丙沙星,诺氟沙星,氧氟沙星,头孢哌酮,头孢泊肟,链霉素,卡那霉素,多西环素,吉西沙星,萘啶酸,呋喃唑酮,呋喃多宁,阿莫西林,和恩诺沙星.
■该研究表明,最大数量的肠杆菌科对美罗培南的作用敏感,属于β-内酰胺类抗生素;对四环素的耐药性得到证实,多西环素,氨苄青霉素,阿莫西林,氧氟沙星,还有头孢泊肟.最常见的编码抗菌素抗性的基因如下:41个和28个分离株的BlaTEM和OXA,分别,编码对β-内酰胺的抗性;在45和48个编码氨基糖苷的分离物中的StrA和StrB;在43和28个编码四环素的分离物中的tetA和tetB。获得的数据表明,不受控制和频繁使用β-内酰胺和四环素抗菌药物,在猫和狗中,结果在肠杆菌科的微生物中传播基因型抗性。
UNASSIGNED: An increasing number of drugs are used each year in the treatment of small pets (cats and dogs), including medicines (cephalosporins and fluoroquinolones) used in human therapy.
UNASSIGNED: The purpose of this study was to isolate and explore the antibiotic resistance of opportunistic Enterobacteriaceae (Escherichia coli, Klebsiella,
Proteus, Ci trobacter, Enterobacter) from cats and dogs, and to isolate resistance genes in the microorganisms.
UNASSIGNED: In 2021, 808 samples of biological material from small domestic animals were collected in veterinary clinics in Kostanay. From these, 210 microorganisms were isolated and identified.
UNASSIGNED: A large majority of the strains sampled belonged to E. coli-149 (70.9%), Enterobacter-11 (5.2%), Klebsiella-28 (13.3%),
Proteus-12 (5.7%) and 10 Citrobacter isolates (4.8%). In all isolates identified, antibiotic resistance/sensitivity was determined by disc-diffusion method to ampicillin, cefoxitin, gentamicin, levomycetin, tetracycline, ciprofloxacin, norfloxacin, ofloxacin, cefoperazone, cefpodoxime, streptomycin, kanamycin, doxycycline, gemifloxacin, nalidixic acid, furazolidone, furadonine, amoxicillin, and enrofloxacin.
UNASSIGNED: The study has demonstrated that the greatest number of Enterobacteriaceae were sensitive to the action of meropenem, which belongs to the group of beta-lactam antibiotics; resistance was demonstrated against tetracycline, doxycycline, ampicillin, amoxicillin, ofloxacin, and cefpodoxime. The most common genes encoding antimicrobial resistance were as follows: BlaTEM and OXA in 41 and 28 isolates, respectively, encoding resistance to beta-lactams; StrA and StrB in 45 and 48 isolates encoding aminoglycosides; and tetA and tetB in 43 and 28 isolates encoding tetracyclines. Obtained data demonstrate that uncontrolled and frequent use of beta-lactam and tetracycline antibacterials, in cats and dogs, results in the spread of genotypic resistance among micro-organisms of the family Enterobacteriaceae.
