[Therapy of staphylococcal endocarditis]. / Zur Therapie der Staphylokokkenendokarditis.

It is reported on the therapy with antibiotics of 5 patients with staphylococcal endocarditis with linkomycin--streptomycin. 2 patients were cured, 2 patients died after disappearing of fever and clinically unequivocally controlled septicaemia of typical complications of ulcerous endocarditis. One patient continued fevering to the exitus letalis when negative blood cultures were present, whereby at post-mortem examination an encephalomalacia with fresh haemorrhage was found to be the cause.

Regression analyses had been made to find interrelationships between the crude fibre content and the EFr content of green feeds. Regression equations were obtained from these analyses which were used to calculate the EFr values, with a sufficient degree of accuracy, from data on the crude fibre content. In these equations the b values were found to be by far more clearly differentiated than in the equations used for calculating digestibility values. These are apparently influenced by the composition of the feeds. The range of variations appears to be only slightly affected when we compare the data with those obtained in calculations made to established the total digestibility values. This is a fact that applies to both the green feeds and their conservation products. Studies investigating the relationships between the content of digestible organic matter (VOS) and EFr (as expressed by the conversion factor (see article) showed that the EFr data could be established, with a fair degree of accuracy, from the VOS values. The f values of the different feeds that were classified into particular groups of feeding-stuffs, were shown to agree fairly well; moreover, they were found to be largely independent of exogenic factors (such as vegetation and N fertilizing). Characteristic differences between the f values of the different conservation products and those of the green feeds were observed although these differences remained within narrow limits (1-3%), so that calculations can be made using only a few factors. When starch equivalents were taken into account it was found that the f values used in calculations for starch equivalents were clearly influenced by feed composition, which, in turn, was influenced by the particular effect of crude values in SE calculations. It is at this point that differences between the two systems of Food Evaluation become particularly apparent. The close relations existing between VOS and EFr values apply, first and foremost, to green feeds and their conservation products. Much wider differences in the f values of different feeds may be observed in the case of foodstuffs having a much more extreme composition. The f values of feedingstuffs with high protein content (e.g. blood meal) may be decreased down to a value of 0.7 while those of foodstuffs rich in fat (e.g. oil cakes or foodstuffs of animal origin containing a high percentage of fat) may be increased up to and over 1.4. In these cases, special circumstances have to be taken into consideration.

Regression techniques may be used to establish close relations between the crude fibre content and digestibility data of organic materials (total digestibility). It was shown from regression equations calculated for a number of feedingstuffs that the total digestibility of a feedstuff may be calculated, with a sufficient degree of accuracy, from the crude fibre content of the material. The range of variations from most of the digestibility data obtained for various feedstuffs, was clearly below the limit given (2.5%). When regression equations are used the variation limits should always be indicated for which they had been established. Differences within the different groups of feedstuffs are so small that in many instances, the same equation may generally be used for feedstuffs of the same group. Similarly, equations for calculating digestibility values may be derived on the basis of the lignin content of a material, although the range of variations will, in this case, be wider when compared with the crude fibre content. The reason for this must be seen in the greater uncertainty of the lignin method. Analogous regression equations may be found for the different conserving products of green feeds, in which certain alterations have to be made corresponding to the different methods of conserving used. On the one hand, these are accounted for by changes in the crude fibre content brought about by biochemical reactions during the conserving process on the other hand a special influence of conserving form can be observed. The content of digestible crude protein in green feeds can be established, with a high degree of accuracy, from the crude protein content of the material. The content of digestible organic matter can be calculated from the digestibility of organic matter and from the ash content of the material. The content of digestible organic matter is, in turn, closely related to the content of energetic feed units in a particular material.
