    Incidence of aerobactin production in Gram-negative hospital isolates (1987)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 43 (1987), S. 0 
    Details
    ISSN: 1574-6968

    Topics: Biology
    Notes: The production of aerobactin was studied in 943 clinical isolates of 14 different Gram-negative genera. Aerobactin-producing strains were isolated in all the genera of Enterobacteriaceae tested, whereas no aerobactin-producing strains were found in the non-enterobacterial genera (Aeromonas, Pseudomonas, Acinetobacter). Enterobacteriaceae might be divided in 2 groups. The first with high incidence of aerobactin-producing strains (more than 40%) comprised the genera of Enterobacter, Shigella and Escherichia. The second, with low incidence of aerobactin-producing strains (less than 20%) comprised the genera Klebsiella, Citrobacter, Proteus, Morganella, Yersinia, Serratia and Salmonella. The production of the siderophore is described for the first time in Citrobacter and Hafnia.

    Aerobactin production and plasmid distribution in Escherichia coli clinical isolates (1989)

    Notes: Abstract The distribution of plasmids as a function of aerobactin production, antibiotic resistance and antimicrobial agents production was studied in 139 Escherichia coli strains obtained from clinical sources. Ninety eight per cent of the strains analyzed presented plasmids with a median value of 2.97 plasmids per cell. Differences in the number of plasmids were observed for aerobactin production (3.52 for aerobactin producing strains, 2.56 (for non-producing ones) and antibiotic resistance (3.19 for antibiotic resistant strains and 2.58 for the sensitive ones). But this was not the case for antibacterial agent production (2.96 for the producing strains, 2.98 for the non-producing ones. Ecological implications of these results are discussed.

    Multifactorial determination of systemic invasivity in Escherichia coli (1986)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 37 (1986), S. 0

    Topics: Biology
    Notes: Abstract Studies of aerobactin excretion, production of antimicrobial agents, haemolysin production, serum resistance and presence of plasmids were made in 157 clinical isolates of Escherichia coli, 96 from blood and 61 from faeces. Only serum resistance and the presence of a small number of plasmids (〈 4 per cell), appeared more frequently in strains from blood than in faecal isolates. It was noteworthy that combination of aerobactin, antimicrobial agents and haemolysin production was more frequent in blood isolates than in strains from faeces. A substantial number of strains from blood presented all 5 virulence factors (9.4%) while none of the faecal strains exhibited this phenotype. Definition of the systemic invasivity of E. coli as a multi-factorial phenomenon is suggested.

    Leuconostoc species as a cause of bacteremia: Two case reports and a literature review (1991)
    Springer

    Notes: Abstract Two new cases of significant bacteremia caused byLeuconostoc spp. are reported and five others described in the literature are reviewed. Four of the seven patients were under one year old and presented with prolonged diarrhea related to gastrointestinal disorders. The remaining three patients were over 50 years of age and being treated in intensive care units. Six patients had nosocomially acquired catheter-related bacteremia.Leuconostoc spp. are naturally resistant to vancomycin, and five patients had received this antibiotic for prior bacteremia caused by methicillin-resistant staphylococci. The majority of patients presented with fever without severe complications. Penicillin is the treatment of choice and there is no report of any death directly attributable to infection by these microorganisms. Infection withLeuconostoc spp. should be suspected if “vancomycin-resistant streptococci” are isolated from the blood, and recorded as a potential cause of bacteremia in patients with indwelling intravenous catheters.

    Retrospective analysis of two hundred and twelve cases of bacteremia due to anaerobic microorganisms (1985)
    Springer

    Notes: Abstract Cases of bacteremia caused by anaerobic microorganisms and occurring during a four year period in a non-selected patient group in a Spanish general hospital were analysed retrospectively. Microbiological data was collected on 212 patients and clinical data on 103 patients. Cases of anaerobic bacteremia represented 8.6 % of the total number of cases of bacteremia. Of the 232 anaerobic microorganism causing bacteremia, gram-negative bacilli were responsible in 113 cases (48.7 %), gram-positive bacilli in 92 cases (39.6 %), grampositive cocci in 25 cases (10.7 %), andVeillonella spp. in two cases (0.8 %). The most important clinical features were fever (64 %), anemia (56 %), septic shock (22 %) and metastatic abscesses (21 %). Patients with anaerobic bacteremia were hospitalized for an average of 51.7 days. The overall mortality was 32 % and factors associated with poor prognosis were severe underlying disease, nosocomial acquisition, presence of shock, presence of metastatic foci of infection, and absence of adequate surgical drainage. The mortality rate of patients who received adequate antimicrobial therapy was 30 % and that of patients who received inadequate treatment or none was 29 %. It is concluded that anaerobic bacteremia has a significant rate of morbidity and mortality and that underlying disease and surgical debridement and/or drainage have greater prognostic significance than the use of antimicrobial agents.
