In a retrospective study, 1538 strains of -haemolysin-producing Staphylococcus species isolated from dermatitis in dogs at three veterinary clinical microbiology laboratories in Norway during 1986–87 and 1993–94 were investigated for their antimicrobial susceptibility. None of the strains was resistant to cloxacillin, cephalexin or the quinolones enrofloxacin and ciprofloxacin. More than 96% of the strains were susceptible to trimethoprim-sulphonamide, bacitracin and fucidic acid. Between 67% and 89% of the strains were susceptible to erythromycin, lincosamides, tetracycline, neomycin and chloramphenicol. Only 37.9% of the strains were susceptible to penicillin. The frequency of penicillin resistance increased significantly between the first and second periods, from 46.0% to 58.6%. The frequency of resistance to lincomycin, clindamycin and erythromycin also increased significantly between the first and second periods, from 3.0%, 2.1% and 3.3% to 25.5%, 19.5% and 24.8%, respectively. A moderate increase in resistance to tetracycline was also noted, from 20.4% in the first to 27.6% in the second period. On the other hand, the frequency of resistance to trimethoprim-sulphonamide decreased significantly from 4.1% in the first to 0.9% in the second period. Many different resistance patterns were observed in each period. However, the proportion of multiresistant strains increased from 2.1% in the first to 10.2% in the second period. There was a decrease in resistance to the combination of trimethoprim-sulphonamide and penicillin from the first to the second period. Resistance to the combination of lincosamides and pencillin increased. For the combinations penicillin-tetracycline-lincosamides, pencillin-lincosamides-erythromycin, and pencillin-tetracycline-lincosamides-erythromycin, there was a striking increase in resistance between the first and the second periods.Abbreviations CVL Central Veterinary Laboratory - NCVM Norwegian College of Veterinary Medicine - NVL Norwegian Veterinary Laboratory  相似文献

Occurrence and health aspects of PCB congeners in freshwater fish     

R Kruse 《DTW. Deutsche tier?rztliche Wochenschrift》1990,97(7):280-284

6 PCB-Congeners, being ruled by the regulatory limits from 23. 3. 1988, are considered to be representative under analytical aspects. The additional consideration of the two further congeners 77 and 118 is recommended under toxicological aspects. A widespread survey is given over the pollution status of marine fish, freshwater fish, and belonging to products. In the years between 1986 to 1988 2229 specimens were analysed for their contents of 8 PCB-Congeners and 6 important chlorinated hydrocarbons. Contents in marine fish were at least 10 times, mostly 100 times lower than regulatory limits. In this area contamination is more influenced by species than by catching grounds. Regulatory limits can however be exceeded in freshwater fish from severely polluted main rivers, where contents are more influenced by catching grounds than by species.  相似文献

Spatial regulators for bacterial cell division self-organize into surface waves in vitro     

Loose M  Fischer-Friedrich E  Ries J  Kruse K  Schwille P 《Science (New York, N.Y.)》2008,320(5877):789-792

In the bacterium Escherichia coli, the Min proteins oscillate between the cell poles to select the cell center as division site. This dynamic pattern has been proposed to arise by self-organization of these proteins, and several models have suggested a reaction-diffusion type mechanism. Here, we found that the Min proteins spontaneously formed planar surface waves on a flat membrane in vitro. The formation and maintenance of these patterns, which extended for hundreds of micrometers, required adenosine 5'-triphosphate (ATP), and they persisted for hours. We present a reaction-diffusion model of the MinD and MinE dynamics that accounts for our experimental observations and also captures the in vivo oscillations.  相似文献

Beitrag zur Morphologie der Infloreszenzen vonSetaria italica (L.) Beauv.     

Joachim Kruse 《Genetic Resources and Crop Evolution》1972,19(1):53-72

Zusammenfassung Es werden verschiedene Infloreszenzformen vonSetaria italica (L.) Beauv. vergleichend morphologisch untersucht. Wie der Vergleich mit der Wildsippe,Setaria viridis (L.) Beauv. zeigt, ist die Entwicklung zur Kulturart mit verschiedenen progressiven Veränderungen im reproduktiven Bereich des Verzweigungssystems verbunden. Dabei führt die zunehmende Förderung der Infloreszenzhauptachse sowie der Partialinfloreszenzen zu einer Vergrößerung und verstärkten Gliederung der Gesamtinfloreszenz. Daneben werden auch regressive Entwicklungstendenzen sichtbar, die in einer zunchmenden Reduktion des Basis- und Spitzenbereichs der Infloreszenz zum Ausdruck kommen. Die stärkste morphologische Ableitung haben Formen mit einer dichotom verzweigten Infloreszenz erfahren. Die Ausprägung der Infloreszenzmerkmale zeigt eine starke Umweltabhängigkeit.

Contribution to the morphology of the inflorescences ofSetaria italica (L.) Beauv.

Summary The morphology of different types of inflorescences were investigated in Setaria italica (L.) Beauv. The comparison with the wild species,Setaria viridis (L.) Beauv., shows that the evolution towards the cultivated species is combined with different progressive changes in the reproductive part of the ramification system. Thereby the increasing promotion of the main axis of the inflorescence as well as the partial inflorescences leads to an enlargement and increased articulation of the whole inflorescence. Besides regressive developmental tendencies are also observed, as expressed by increasing reduction of the basis and the top of inflorescence. The greatest deviation is seen in the form with dichotomous branched inflorescences. The characters of the inflorescences depend greatly on the environmental conditions.
