[The acid-base equilibrium and carbohydrate metabolism during infection with Eperythrozoon suis].
Following on from clinical observations which point to severe metabolic disturbances in association with acute Eperythrozoon (E.) suis infection, the parameters of acid-base balance (pO2, pCO2, pH, actual bicarbonate, standard bicarbonate, base excess) as well as the glucose-, lactate- and pyruvate levels, were measured in venous blood during the course of eperythrozoonotic infection. Glucose consumption was investigated in in vitro experiments with differing numbers of pathogens. Acute E. suis infection is accompanied by a severe acidosis and hypoglycaemia. In vitro experiments showed that a rapid breakdown of glucose follows in E. suis infected blood. No significant reduction in glucose concentration was established in control blood in a comparable time period. The results give rise to the assumption that E. suis is capable of independent glucose breakdown. Both the increase in lactate concentration (metabolic component) and a disturbance of pulmonary gaseous exchange (respiratory component) are regarded as the cause of the acidosis.
