It is known that high temperature is a leading clinical symptom of infectious disease. Obtained hemoculture confirms the presence of microorganisms in blood. The authors compared the clinical symptoms of bloodstream infection with the results of microbiological blood tests. There were 204 patients interviewed according to a special questionnaire. All patients, blood was analysed by microscopic and cultivation tests. The leading clinical symptoms of patients with BI were: high temperature and chill (63,2%), skin abscesses (72,1%), diseases of upper respiratory tract (63,7%) and unstable stool (diarrhea or constipation) (53,9%). Blood was collected in anticoagulant to have buffy-coat layer which was used for the blood smears and blood culture.
The blood smears for microscopic examination were painted using Gram method.
Blood cultures were kept in aerobic and anaerobic conditions. The microorganisms were discovered in 97,8% of the blood smears as monomorphologies (17,4%) and associations of morphological forms (82,6%). The microorganisms were isolated in 55,2% of blood samples as monomorphologies (64,3%) and associations of morphological forms (35,7%).
