Human, cattle and goat blood as substitutes for sheep blood in blood-supplemented culture media

Pig and goat blood as substitutes for sheep blood in blood-supplemented agar media.

In many developing countries sheep and horse blood, the recommended blood supplements in bacteriological media, are not readily available, whereas pig and goat blood are. Therefore, this study examined the use of pig and goat blood as potential substitutes for sheep blood in blood-supplemented bacteriologic media commonly used in clinical microbiology laboratories. In general, the growth charac...

Blood and blood substitutes.

Each year, in Europe, approximately seven million units of colloidal plasma substitutes are given to patients. Often they are used uncritically, which may account for the increased incidence of sideeffects which has been noted over the last decade. Their increasing use is understandable in view of the disadvantages of using blood; these include the difficulties in finding sufficient donors of a...

Blood substitutes

Blood substitutes have long been sought after, and artificial oxygen carriers may soon become a reality. Despite increased safety of allogeneic blood in terms of transmission of infectious diseases [1], avoiding allogeneic blood transfusions remains an important goal in perioperative and intensive care medicine. This is because allogeneic blood transfusions may cause immunosuppression with an i...

Microcalorimetry as a tool for evaluation of blood culture media.

Evaluation of optimal compositions of blood culture media has called for extensive and laborious work in comparative studies of large series of clincal specimens. Bacterial growth is accompanied by heat production, and calorimetry provides an analytical tool for its detection and quantification. A twin microcalorimeter of the heat conduction type was used to register heat effects in experimenta...
