Resistance to penicillin in neisseria gonorrhoeae

The incidence of Neisseria gonorrhea [NG] strains resistant to penicilline have increased. We evaluated this incidence from 1989 to 1991. First penicillinase-producing NG strains were isolated in 1989. in 1991, these strains represented 45% of isolates. Epidemiologic survey NG strains was then necessary

Staphylococcal urinary infection. Bacteriological study

143 strains of staphylococcus saprophyticus were isolated from urines of patients with urinary tract infections during a 6 years period [1985-1990]. The diagnostic was based both on cytological and bacteriological studies. The identification of genus staphylococcus and of coagulase negative species was done by using conventional methods. The identification of the type was done by the [Api Staph] micromethod and the resistance to novobiocin. Antimicrobial susceptibility tests were performed by a disk diffusion method. Resistance phenotypes to beta lactams, aminoglycosides and macrolides were established. 94% of the urinary tract infections were observed among young women mainly from prenatal consultation [78%]. In all cases, bact‚riuria was > 10[5] CFU/ml and pyuria > 10[4] /ml. Among these patients, SS was the second species isolated after E. coli. Contrarely to the hospitalized patients for whom proteus mirabilis was in the second place. The SS isolates were generally sensitive to antibiotics except to lincomycin [38% of sensitive strains]. The susceptibility to antibiotics with renal diffusion and urinary elimination, such as ampicillin and sulfamethoxazol-trimethoprim was satisfactory [respectively 74 and 100%]

Les endocardites a staphylocoque coagulase negative

15 endocarditis of NCS were studied among a period of 3 years [January 1983- January 1986]. They represent 42% of all the bacterial endocarditis. The entrance is especially iatrogenic [intra veinous catethers] and the staphylococcic the more often found is the epidermidis staphylococcis. The mitral localisation of the bacterial endocarditis prevails as with NCS as with the other germs. The NCS characteristic is to engender endocarditis on prosthesis with a great frequency than the other germs, this due to their adherence with the prothesis material. Finally, they are of a prognosis more better than the other bacterial endocarditis
