[Pediatric bacteremia strains grow in blood culture media].

Bacteremia strains may influence the clinical therapy, the isolation of bacteremia strains is important for patients. In order to understand the distribution and the growth in the blood culture media of bacteremia strains, from January 1982 through December 1988 we studied the blood culture sent to us from the pediatric ward. These were three hundred and forty one bacterial strains (3.1%) isolated from patients. In the meantime we also studied the bacteremia strains growth in the blood culture media. In these positive cultures, there were 83 gram-positive, and 258 gram-negative strains. The 83 gram-positive included Staphylococcus aureus (38 strains), hemolytic streptococcus (22 strains), Enterococcus (13 strains), Streptococcus pneumoniae (8 strains) and others (2 strains). The 258 gram-negative strains included Escherichia coli (97 strains), Salmonella spp. (43 strains), Enterobacter spp. (31 strains). Klebsiella spp. (23 strains), Pseudomonas spp. (25 strains), Proteus spp. (17 strains), Citrobacter spp. (11 strains) and others (11 strains). The Growth of bacteremia strains in the blood culture medium, showed that first day isolation strains were 33.7%, second day strains 24.9%, third day were 19.9%, fourth day were 13.5%, fifth day were 3.2%, sixth day were 4.1% and seventh day were 0.6%. In conclusion, the bacteremia strains showed that the gram-negative, which were 75.7%, were more prevalent than the gram-positive which were 24.3%, the isolation of the strains was more in the first to fourth day and grew by 92%, on the fifth day it grew by 3.2% and on the seventh day by only 0.6%. On the fifth day the baby had recovered and we were able to discontinue antibiotic therapy.
