    Nitrat ve nitrit'in farelerde immunosupresif etkileri üzerinde araştırmalar
    (Uludağ Üniversitesi, 1987) Kahraman, Mustafa; Uludağ Üniversitesi/Veteriner Fakültesi/Mikrobiyoloji Anabilim Dalı.
    Eighty white mice, which were a month of age, were divided into four equal numbered groups and were fed for six months under the same circumstances. During this period 400 mg/lt of NaN02 and NaN03 were added into the drinking water of third and {ourth groups, respectively . At the end of six months, all groups except for the first one were injected Hitchner B1 (10 /D/0.25 ml) of Newcastle virus (NV) by way of subcutan three times at one day intervals. Fifteen days after the last injection blood was taken from all the animals in separate groups;serums were prepared arıd examined by means of Hemagglutination-inhibition (H tests. Asa result, the tillers of the four different groups were found to be 2- l , 2- , 2- 5 and 2 -4 HI tilers respectively. Meanwhile, immunosuppressive effect was observed in the third and {ourth groups, into whose drinking water nitrite and nitrate were added.

    Nitrat ve nitrite bağlı immunosupresif etki oluşturan farelerde bazı biyolojik değişiklikler üzerinde araştırmalar
    (Uludağ Üniversitesi, 1987) Kahraman, Mustafa; Yaman, Kemalettin; Uludağ Üniversitesi/Veteriner Fakültesi.
    Eighty Swiss mice divided into 4 groups were used. Blood samples were taken from four animals randomly selected to obtain the hematocrit values, hemoglobin levels, red (rbc) and white (wbe) blood cell counts. The groups were J. Negative controls. ll. Vaccinated with Hitehner B 1 New· east/e vaccine, lll. Treated with nitrite and I V. Treated with nitrate in their drinking water. The respective hematocrit values were 47, 45, 41, 45 per cent, while the hemoglobin levels were 10. 7, 10.9, 9. 7. 10.3 g (s) which were considered in the normal limits.

    Sığırlarda mastitis üzerinde araştırmalar 3. E. Coli'e bağlı mastitis
    (Uludağ Üniversitesi, 1987) Kahraman, Mustafa; Uludağ Üniversitesi/Veteriner Fakültesi.
    CMT (California mastitis test) was applied to 248 milk samples. 135 samples were found to be mastitis positive. E. coli strains were isolated from 22 of the mastitis positive samples being either pure or mixed other microorganisms. The isolates were tesled {or susceptibility agaitıst 10 antibiotics and turned out to be susceptible against them. These antibiotics are: Chloramphenicol, tetracycline, streptomycin, neomycin, oxytetracycline ampicillin, Geopen. However, all isolates showed resistance against three antibiotics: penicillin, erythromycin, colisin.
