Studies on gentamicin-induced nephrotoxicity in rats
1986
Cho, I.S. | Kim, T.J. | Yoon, H.J. (Konkuk Univ., Seoul (Korea R.). Dept. of Veterinary Medicine)
Sprague-Dawley rats received subcutaneous injections of gentamicin sulfate, 50 and 100mg/kg for 3, 7 and 10 days. The hematological and blood chemical values were determined. Kidneys were examined histologically and ultrastructurally. The serum values of aspartate transaminase, blood urea nitrogen and creatinine in the rats administered gentamicin, 50 and 100mg/kg/day were significantly increased than those in the control. The ratio of kidney weight to body weight was significantly increased in the rats injected gentamicin, 100mg/kg for 10 days than those in the control

1986
Choi, W.P. | Park, N.C. | Lee, G.L. (Kyongbuk National Univ., Taegu (Korea R.). Dept. of Veterinary Medicine)
This paper deals with the incidence of bovine mastitis for 743 quarters and distribution of Staphylococci for the quarter and 70 bulk milk samples in the northern area of Kyongbuk during the period from Jan to Dec 1984. Isolated Staphylococci were examined for species, subgroups, antibiotic resistance and penicillinase production. A total of 25 (73.5%) of 34 herds, 102 (54.3%) of 188 cows and 208 (30.3%) of 743 quarters were found to be infected with subclinical mastitis. A total of 83 (83.1%) of 102 cows, 94 (45.2%) of 208 mastitic quarters and 55 (78.6%) of 70 bulk milk samples were isolated Staphylococci

Suceptibility to animal serum and antimicrobial agents of campylobacter jejuni isolated from pigs and chicken
1989
Lee, S.C. | Kang, H.J. (Kyongsang National Univ., Chinju (Korea R.). Coll. of Veteinary Medicine)
A total of 108 strains of C jejuni isolated from pigs and chickens were examined for the susceptibility to 10 antimicrobial agents and normal sera of cattle, sheep, guinea pigs and chickens. Minimal inhibitory concentration (MIC) ranges of antimicrobial agents to C jejuni isolates were = 100 micro g/ml for erythromycin, rifamycin, streptomycin and tetracycline, 50 to 100 micro g for cephalothin, = 50 micro g for ampicillin,

1989
Cho, G.J. | Kim, B.H. | Tak, R.B. (Kyongbuk National Univ., Taegu (Korea R.). Coll. of Veterinary Medicine)
The capsular serogroupes and drug susceptibility of 111 isolates of Pasteurella multocida from pigs with atrophic rhinitis and pneumonic lesions were investigated. Of the 111 P multocida isolates, 42 were from lung lesions, 47 from nasal turbinate lesions and the remaining 22 from the nasal swabs. P multocida isolates were typed for capsular serogroupes A by hyaluronidase inhibition of capsule and D by acriflavine auto-agglutination. Most isolates (64.9 %) were type A, 23.4 % were type D and the remaining 11.7 % were untypable. Resistance to triple sulfa (97.3 %) was most frequent, followed by resistance to tiamulin (71.2 %), tylosin (56.8 %), streptomycin (36.9 %), and neomycin (36.0 %). The majority of the organisms were susceptible in order of prevalence to baytril (100 %), ampicillin (98.2 %), linsmycin (97.3 %), cephalothin (94.6 %), gentamycin (93.7 %), amikacin (92.3 %), tetracycline (91.9 %), trimethoprim/sulfamethoxazole (91.0 %), and kanamycin (90.1 %). No differneces in drug resistance in relation to capsular serogroupes of P multocida and the origin of lesions were noted. A high prevalence of multiple drug resistance was observed and the most common resistant patterns were Sss, Tm, Ty (12.6 %) and Sm, Sss, Tm, Ty (8.1 %) patterns
