Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The article presents the results of the study of antibiotic resistance of Staphylococcus aureus bacteria isolated from livestock products (meat, milk and eggs) of Almaty region. From 146 investigated samples of animal products, Staphylococcus aureuswas isolated in 43 cases, with the most frequent isolation of the microbe from beef meat in 19.7%, lamb 10.9%, pork 7.3%, fowl 7.2% cases. Resistance to antibiotics of beta-lactam group, tetracycline and aminoglycosides was detected in 9 (20.9%) of 43 isolates of Staphylococcus aureus. Resistance to vancomycin, clindomycin, linezolid, gentamicin, norfloxacin, chloramphenicol and trimethoprim sulfamethoxazole was not recorded. The highest number of resistant isolates was observed for oxacillin (4.6%), benzylpenicillin (4.6%), doxycycline (4.6%), tetracycline (4.6%), and the lowest for amikacin (2.3%). From 43 tested isolates of Staphylococcus aureus, 34 (79%) remained sensitive to all antibiotics tested. В статье представлены результаты исследования антибиотикорезистентности бактерий Staphylococcus aureus, выделенных из животноводческой продукции (мясо, молоко и яйца) Алматинской области. Из 146 исследованных образцов продуктов животноводства Staphylococcus aureus выделен в 43 случаях, при этом, наиболее часто микроорганизм выделялся из мяса говядины – в 19,7%, баранины – 10,9%, свинины – 7,3%, курятины – 7,2%. Резистентность к антибиотикам группы бета-лактамы, тетрациклинового ряда и аминогликозидам была выявлена у 9 (20,9%) из 43 изолятов Staphylococcus aureus. При этом устойчивость к ванкомицину, клиндомицину, линезолиду, гентамицину, норфлоксацину, хлорамфениколу и триметоприму сульфаметоксазолу не зафиксирована. Наибольшее количество резистентных изолятов отмечено к оксациллину (4,6%), бензилпенициллину (4,6%), доксициклину (4,6%), тетрациклину (4,6%), наименьшее – к амикацину (2,3%). Из 43 исследованных изолятов стафилококков 34 (79%) сохраняли чувствительность ко всем тестируемым антибиотикам.
