    Determination of calpastatin (CAST) gene polimorphism in some native sheep breeds reared in Turkey by PCR-RFLP method [Türkiye’de yetiştirilen bazı yerli koyun irklarında kalpastatin (CAST) geni polimorfizminin PCR-RFLP yöntemiyle belirlenmesi]
    (Ankara University, 2014) Balcioğlu M.S.; Karsli T.; Şahin E.; Ulutaş Z.; Aksoy Y.
    In this study, calpastatin (CAST) gene polimorphism was investigated in 7 native sheep breeds reared in Turkey by using PCR-RFLP method. The frequencies of M and N alleles of CAST gene in Kangal (n= 31), Awassi (n= 26), Güney Karaman (n= 23), Akkaraman (n= 21), Morkaraman (n= 34), Karayaka (n= 33), and Karakas (n= 22) sheep breeds were determined as 0.92-0.08, 0.59-0.41, 0.67-0.33, 0.69-0.31, 0.87-0.13, 0.86-0.14, 0.89-0.11 respectively. According to chi-square test, all the other populations were consistent with Hardy-Weinberg equilibrium, whereas Morkaraman, İvesi and Karayaka populations showed significant (P<0.05) deviation from Hardy-Weinberg equilibrium for the CAST gene. © Ankara Üniversitesi Ziraat Fakültesi.

    The antimicrobial susceptibility of Moraxella species other than Moraxella catarrhalis [Moraxella catarrhalis dışı Moraxella türlerinin antibiyotik duyarlılığı]
    (Turkiye Klinikleri, 2015) İşeri L.; Apan T.; Şahin E.
    Objective: Although Moraxella species are members of the normal respiratory flora, some species, including M. catarrhalis, M. osloensis, M. nonliquefaciens, and M. lacunata, can cause serious infections in humans. The purpose of this study was to investigate the antimicrobial susceptibility of Moraxella species other than M. catarrhalis. Material and Methods: The study included 17 M. osloensis, 18 M. lincolnii, and three M. nonliquefacie, isolated from 100 nasopharyngeal samples. The isolates were identified by conventional methods. Identification to the species level was performed by a RapID NF Plus identification kit (Remel, USA). The antimicrobial susceptibility of the isolates was examined for ampicillin, amoxicillin/clavulanic acid, gentamicin, ceftazidime, ciprofloxacin, erythromycin and trimethoprim-sulfamethoxazole using the disk diffusion method. The results were evaluated according to guideline published by the Clinical and Laboratory Standards Institute. ß-Lactamase production was tested using nitrocefin discs. Results: The resistance rates of isolates were between 3% and 8% for trimethoprim-sulfamethoxazole, amoxicillin/clavulanic acid. Inhibition zone diameters for ampicillin of 41% of M. osloensis, 33% of M. nonliquefaciens, and 11% of M. lincolnii isolates were relatively small (?15 mm). Five M. osloensis (29%) and one M. nonliquefaciens, isolates were beta lactase positive. Conclusion: Moraxella species other than M. catarrhalis can cause serious infections in humans. Therefore, we suggest that Moraxella species other than M. catarrhalis should be included in surveillance studies. © 2015 by Türkiye Klinikleri.
