Popis: From different samples of 247 diseased animals (cattle, sheep, goat, horse, pig, dog, cat, rodent, zoo-animals), 410 strains of gram-negative anaerobes were cultured. 297 isolates (72.4%) could be differentiated to the species level by using cultural-biochemical methods, gaschromatography and cell-wall-lipidanalysis. They belonged to 29 different species. For an additional 113 strains (27.6%) only the genus could be determined. Bacteria belonging to the genus Fusobacterium occurred with the highest isolation rates (36% of all strains) in the samples examined, followed by Bacteroides spp. (26.1%), Prevotella spp. (19.9%) and Prophyromonas spp. (17.8%). Fusobacterium necrophorum was the single species isolated most frequently. Antibiotic susceptibility tests by E-test were performed on 100 strains belonging to the the above mentioned genera. Of these strains 18% were resistant to penicillin and 20% to tetracycline. The resistant strains belonged mainly to the Bacteroides fragilis-group. Resistant rates to most other antimicrobial agents tested were Amoxicillin in combination with clavulanic acid: 1%, Chloramphenicol: 3%, Clindamycin:8%. All 100 selected strains proved to be susceptible to Metronidazol.
