Abstract

This study was conceded to examining the occurrence of possible pathogenic species of bacterium in C. zillii in the Al-Diwaniya River. A total of 100 fishes of C. zillii, during the period (April) 2021 till (March) 2022. Bacteria were recognized using the VITEK 2 system and designated biochemical tests. Species were recognized with different percentages in C. zillii, P. luteola, S. thalpophilum, S. lentus, and A. sobria. Antimicrobial susceptibility test of 16 antimicrobials, which are (Ampicillin, piperacillin/tazobactam, amikacin, cefazolin, Ceftriaxone, Ertapenem, Gentamycin, cefoxitin, ciprofloxacin, imipenem, ceftazidime, levofloxacin, cifepime, tigecyclin, Nitrofuran, and trimethoprime- sulphamethoxazole) was recognized and studied for antimicrobial susceptibility test using the Vitek II system. The best antimicrobial susceptibility were ciprofloxacin (<= 0. 11μg/ ml), Imipenem (<= 0. 25, μg/ ml), when tested in vitro on P. luteola, S. thalpophilum, S. lentus, A. sobria, and Livofloxacin (<= 0. 22, <= 0. 20, <= 0. 25, <= 0. 21, μg/ ml), when examined in vitro on P. luteola, S. thalpophilum, S. lentus, A. sobria while, it was resistant to cefazolin ( > = 70, >= 70, > = 76, >= 68, μg/ ml), when examined in vitro on P. luteola, S. thalpophilum, S. lentus, A. sobria. Keywords: Coptodon. zillii bacteria Antibiotics, Iraq.

伊拉克中部Al-Diwaniya河zillii Coptodon细菌的分离鉴定及一些毒力因子的研究

本研究旨在调查Al-Diwaniya河中可能的致病性细菌种类。2021年(4月)至2022年(3月)期间，共100条紫棘鱼。使用VITEK 2系统和指定的生化测试识别细菌。紫百合、木犀草、thalpophilum、lentus和sobria的物种识别率不同。对氨苄西林、哌拉西林/他唑巴坦、阿米卡星、头孢唑林、头孢曲松、厄他培南、庆大霉素、头孢西丁、环丙沙星、亚胺培南、头孢他啶、左氧氟沙星、西非平、替加环素、硝基呋喃、甲氧嘧啶-磺胺甲氧嘧啶等16种抗菌素进行了药敏试验，并采用Vitekⅱ系统进行了药敏试验。其中环丙沙星的药敏率最高(<= 0;11μg/ ml)，亚胺培南(<25， μg/ ml)，对木犀草、thalpophilum、S. lentus、A. sobria和利福沙星进行体外实验(<= 0。22， <= 0;20， <= 0;25、<= 0;21， μg/ ml)，体外对木犀草、thalpophilum、S. lentus、A. sobria检测，同时对头孢唑林(>= 70， >= 70， >= 76， >= 68， μg/ ml)，体外对木犀草、thalpophilum、lentus、A. sobria进行检测。关键词:Coptodon。产自伊拉克的zillii细菌抗生素。
