| comparative bacteriological studies on summer mastitis in grazing cattle and pyogenes mastitis in stabled cattle in denmark. | a total of 143 secretions from clinical cases of summer mastitis (sm) in grazing cattle and from 89 cases of pyogenes mastitis (pm) in stabled cattle were examined bacteriologically. the typical bacteriological finding was a mixed flora in which the predominant organisms were actinomyces pyogenes (sm-70%, pm-85%), peptostreptococcus indolicus (54%, 54%), a microaerophilic coccus (stuart-schwan coccus) (26%, 25%), fusobacterium necrophorum biovar b (22%, 12%), bacteroides melaninogenicus (20%, 9% ... | 1992 | 1355316 |
| ribotyping to differentiate fusobacterium necrophorum subsp. necrophorum and f. necrophorum subsp. funduliforme isolated from bovine ruminal contents and liver abscesses. | differences in biological activities (hemagglutination, hemolytic, leukotoxic, and virulence) and ribotypes between the two subspecies of fusobacterium necrophorum of bovine ruminal and liver abscess origins were investigated. hemagglutination activity was present in all hepatic, but only some ruminal, strains of fusobacterium necrophorum subsp. necrophorum. ruminal f. necrophorum subsp. necrophorum had low leukotoxin titers yet was virulent in mice. fusobacterium necrophorum subsp. funduliforme ... | 1996 | 8593050 |
| stability and stabilization of fusobacterium necrophorum hemolysin. | the stability and stabilization of the hemolytic activity of fusobacterium necrophorum subsp. necrophorum and fusobacterium necrophorum subsp. funduliforme were monitored over a period of four weeks using culture supernatants. the hemolytic activity was completely lost after one week at room temperature and 37 degrees c. after a two-week storage at 4 degrees c and -80 degrees c only trace activity was detected with -80 degrees c being the better of the two conditions. the addition of cysteine mo ... | 1996 | 8810016 |
| endotoxin-triggered haematological interactions in fusobacterium necrophorum infections. | the haematological mechanisms in the course of liver abscess formation were evaluated. they were examined by employing viable cells of fusobacterium necrophorum subsp. necrophorum and fusobacterium necrophorum subsp. funduliforme in comparison with their endotoxins. whole cell infection with f.n. necrophorum led to neutrophilia and to a concomitant monocytosis in parallel with those responses induced by the in vivo injection of its endotoxin. viable infection with f.n. funduliforme was character ... | 2000 | 10817519 |
