    Detection of rope-producing bacillus in bread and ıdentification of ısolates to species level by vitek 2 system
    (Uludağ Üniversitesi, 2012-09-24) Yibar, Artun; Cetinkaya, Figen; Soyutemiz, Gul Ece; Veteriner Fakültesi
    This study was conducted to detect the presence of rope-producing Bacillus spp. and the rope spore counts in one hundred samples of different types of bread obtained from several bakeries and supermarket stores in Bursa province and to identify the isolates at the species level. Rope spore counts determined using the Most Probable Number (MPN) technique varied between 30 and 90 MPN/g in eight samples while this count was 11 000 MPN/g in one sample. By VITEK 2 bacterial identification system, eight of Bacillus strains isolated were identified as B. cereus and one as B. subtilis. Additionally, it was observed the growth of yeast and mould in the counts varying between 1x102 and 6.3x104 cfu/g in the samples. The results indicated that breads analysed harboured Bacillus species which can be responsible for rope spoilage of bread or food poisoning in humans

    Evaluation of faecal shedding of acid-fast mycobacterium avium subsp. paratuberculosis (map) in both intradermal johnin test- and serologically (Elisa) mappositive cattle

    Paratuberculosis is a debilitating disease of livestock caused by Mycobacterium avium (MAP). As a result of economic impact caused, disease is now one of the most important problems of dairy industry. Detection of animals shedding MAP organism plays a crucial role in herd eradication of the disease. Aim of the presented study was to evaluate relationship between MAP ELISA results, Intradermal Johnin test and fecal MAP shedding ratio. 40 ELISA and Johnin test positive animals were selected for the study. 25 of 40 animals (62.5%) were shedding MAP organisms with their feces. Results of the present study indicate that combination ELISA and Johnin test results is a useful tool for prediction of animals shedding MAP.

    Improving conception rate in lactating dairy cows by using modified ovsynch protocol during summer

    The aim of this study was to test two different timed artificial insemination (AI) protocols in order to improve the percentage of pregnant cows per AI in lactating dairy cows during the summer. Cows (n=140) were randomly divided into two groups; cows in the OVS group (n=75) received the Ovsynch protocol (GnRH–7d–PGF2α–2d–GnRH–16h–AI), and cows in the MOVS group (n=65) received the Ovsynch protocol with exogenous progesterone (P4) which administrated between GnRH and PGF2α. In addition, GnRH was injected 7 d after AI in the MOVS group (GnRH–P4–7d –PGF2α–2d–GnRH–16h–AI–7d–GnRH). Response to the second GnRH treatment of Ovsynch (GnRH-2) was greater (P<0.03) in the MOVS (98.5%) than the OVS (89.3%) group. Although P/AI at 31 d was numerically greater in the MOVS (46.2%, 30/65) than the OVS (37.3%, 28/75) group, this difference was statistically insignificant. Thus, because of the greater response to GnRH-2 and P/AI in MOVS compared with the OVS group, the MOVS protocol can be used to improve P/AI in lactating dairy cows during the summer, but further studies are needed to be evaluated the effects of the MOVS protocol on P/AI during the summer.
