    AN EVALUATION OF A CURRENT RECOGNITION MEDIUM FOR DIAGNOSIS OF S. AUREUS
    (2020-12-22) Mustafa Salah Hasan
    Staphylococcus aureus is a significant pathogen which is life-threatening in human and animals. This study was conducted to assess the newly prepared medium to identify S. aureus. Three isolates of S. aureus and 3 isolates of coagulase-negative staphylococci (CNS) were used in this study. The media contains agar, maltose, peptone water, and bromocresol purple as a pH indicator. The results showed yellow colonies of S. aureus with a zone of inhibition and white to purple colonies of CNS without inhibition zone. In conclusion, this current medium can be used to identify S. aureus quickly

    The Effect of Erythritol Injection in Decreasing of Abortion Rate in Local Breed Ewes
    (2023-04-25) Mustafa Salah Hasan
    -is study designed to evaluate the e1ect of Erythritol injection in decreasing of abortion rate in local breed ewes. Fifty pregnant ewes from local breed aged 2–4 years with a history of abortion except G1, were fed ad libitum hay and grains with water. -e study was carried out in Salah Aldein province at special farm at a period of July–November 2022. -ese animals were tests for brucella by using rose Bengal and ELISA at zero day for con;rmation; these animals were divided into 5 groups: G1 was brucella −ve and pregnant at 60 days, G2 was brucella +ve and pregnant at 60 days, G3 brucella+ve pregnant animals and treated by antibiotics gentamicin 10%, 3 ml/ animal for 3 days, G4 brucella +ve and pregnant and giving erythritol, 10 ml S/C of 10% solution (solve in water and glycerol), and G5 was brucella +ve, and all pregnant and giving Erythritol+ gentamycin 10%, 3 ml/animal for 3 days.-eexperiment takes 12 weeks. Blood was withdrawn at di1erent times of experiment (0, 2 weeks and end of experiment). -e seroprevalence of brucellosis was shown that all animals at G4 and G5 where seropositive after 14 days of experiment, at end of pregnancy the seropositivity were highly signi;cantly in G4 and G5 as compared with another groups. -e current results showed that percentages of abortion were higher in G2, followed by G3, while it has been reduced signi;cantly in G4 and G1. In conclusion, Erythritol alone can decrease the rate of abortion by making the bacteria extracellular far from placenta and evading of infection by immunity and/or gentamicin injection. Also, erythritol can be used as elicit diagnosis of brucellosis in latent infected animals.
