In vitro antimicrobial susceptibility tests were carried out on 48 strains of Prototheca zopfii, an achlorophyllous algae causing refractory mastitis in dairy cows; 27 antimicrobials were evaluated. All strains were susceptible to both myxin and nystatin. In addition, 22 strains were susceptible to amphotericin B, 21 to polymyxin B, and 18 to gentamicin. Only 1 strain was susceptible to kanamycin. All strains were resistant to ampicillin, bacitracin, carbenicillin, cephalothin, chloramphenicol, clotrimazole, cloxacillin, erythromycin, flucytosine, ketoconazole, lincomycin, miconazole, neomycin, nitrofurazone, novobiocin, oleandomycin, penicillin, rifampin, streptomycin, tetracycline, and vancomycin.
对48株引起奶牛顽固性乳腺炎的无叶绿素藻类——佐夫原藻进行了体外抗菌药敏试验；评估了27种抗菌药物。所有菌株对粘菌素和制霉菌素均敏感。此外，22株对两性霉素B敏感，21株对多粘菌素B敏感，18株对庆大霉素敏感。仅1株对卡那霉素敏感。所有菌株对氨苄西林、杆菌肽、羧苄西林、头孢噻吩、氯霉素、克霉唑、氯唑西林、红霉素、氟胞嘧啶、酮康唑、林可霉素、咪康唑、新霉素、呋喃西林、新生霉素、竹桃霉素、青霉素、利福平、链霉素、四环素和万古霉素均耐药。
