RESUMEN
Lactococcus lactis cremoris is rarely involved in human pathology. A thirty two-year old pregnant woman with premature rupture of membrane history presented with chorioamnionitis due to L. lactis cremoris. She underwent an emergency caesarian section and was treated with antibiotics including the association of amoxicillin and clavulanic acid. She was completely recovered. This is the first case to our knowledge of chorioamnionitis due to this organism.
RESUMEN
Urinary tract infection (UTI) in children is a grave pathology, which requires a fast and effective care. Bacteriological and epidemiological data play a determining role in patient's care. We report a retrospective study, which spreads out from January 1st till August 31st, 2009, having concerned hospitalized children for urinary infection in pediatrics service of Farhat Hached teaching hospital in Sousse. Our series contained 51 children with a sex ratio of 0.76, an average age of 32 months. The majority of cases was pyelonephritis (94.1%). A pathology is associated with the urinary infection in 41.2%. Three cases of vesico-ureteral reflux were noted. The diagnosis of urinary infection was confirmed by cytobacteriological exam of urine (CBEU). Enterobacteriacea were isolated in 96.1%. Escherichia coli remains the most often isolated (80.4%), followed by Klebsiella pneumoniae (9.8%) then by Proteus mirabilis (5.9%). E. coli was resistant to amoxicillin in 78% of cases, to the association amoxicillin-clavulanic acid in 64,8%, to cephalosporins of 3(rd) generation (C3G) in 5% and to cotrimoxazole in 51%. No K. pneumoniae or P. mirabilis strain was resistant to C3G. UTI in children is always an indication for CBEU realization at first intention. The results of this exam are very important considering the diversity of the responsible bacteria and the growing frequency of acquired antibiotic resistance.

To determine the role and importance of beta-haemolytic streptococci in acute pharyngitis and its relative susceptibility to antibiotics, we cultured samples from 143 patients (age range: 3-72 years) who presented over a 5-month period in 2001 at three primary health care centres in Sousse, Tunisia. The cultures yielded 80 beta-haemolytic streptococci (59 group A streptococci and 21 non-group A streptococci). All strains were susceptible to benzylpenicillin, amoxicillin, chloramphenicol, rifampicin and pristinamycin. Susceptibility was variable in erythromycin, tetracycline, fosfomycin, telithromycin and levofloxacin. Minimum inhibitory concentrations were determined by E-test for penicillin, erythromycin and levofloxacin. Our results confirm that penicillin is still the reference treatment for acute pharyngitis. However, to minimize the potential for complications arising from its use, continued vigilance is required.
