INTERET DU SCANNING AU CITRATE DE GALLIUM 67 DANS LA CHIRURGIE DE LA HANCHE SUSPECTE D'INFECTION

The authors present their first results of Gallium 67 scintigraphs obtained on hips subjected to operation. In a series without any septic incident, 91% of the scans remained negative. In all of the cases of infected hips, whether early or late, the scintigraphs were 100% positive. This examination is very reliable and should be done for the removal of all doubt every time that there is suspicion of infection of a hip.SCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

Bactericidal effect and regrowth of Streptococcus faecalis exposed to amoxicillin following β-lactamase

Streptococcus faecalis usually requires high concentrations of penicillin or ampicillin to achieve killing (i.e. a high MBC/MIC ratio). However, most strains show the Eagle or paradoxical effect. We subjected 12 strains of S. faecalis to 0.1, 1, 10 and 100 μg/ml of amoxicillin. Turbidometry studies have shown that 3 h after the inactivation of amoxicillin by penicillinase, there was a longer effect for 1 μg/ml following β-lactamase (12 h 31 min ± 2 h 09 min) than for 10 μg/ml (7 h 0 min ± 1 h 12 min) or 100 μg/ml (5 h 22 min ± 0 h 52 min). After 3 h, the reduction of CFU/ml (inoculum 106 CFU/ml) was -1.8 ± 0.6 for 1 μg/ml, -0.56 ± 0.56 for 10 μg/ml and -0.21 ± 0.20 for 100 μg/ml. The more rapid killing at 3 h was not the only reason for the longer effect following β-lactamase observed with 1 μg/ml. Indeed, the growth curve obtained with an inoculum of 103 CFU/ml was 2 h delayed from the control curve (106 CFU/ml). In conclusion, a paradoxical effect (killing curves and effect following β-lactamase) was observed for all S. faecalis strains included in this series.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
