The in vitro antibacterial activity of zidovudine alone and in combination with ciprofloxacin was investigated. Zidovudine showed a good activity against Escherichia coli and Salmonella (MIC range 0.5-8 micrograms/ml and 1.5-62 micrograms/ml respectively) isolated from biological samples of HIV-infected patients. These strains proved to be extremely(More)
HIV infection is thought to exacerbate the virulence of normal saprophytic vaginal microflora. We studied the vaginal ecosystem of HIV patients to detect the quantitative and qualitative variation of vaginal microorganisms. 15 patients (5 with AIDS and 10 with ARC) were investigated. Vaginal candidiasis was more frequent in this group than in the control(More)
Forty-four Mycobacterium-spp. were isolated in 33 patients from an infectious diseases ward. All patients were HIV-positive and most of them were drug-abusers. M. avium-intracellulare was the most common type of MOTT (Mycobacteria other than tuberculosis) detected and the only microorganism isolated in patients with mycobacteriaemia. The radiometric method(More)
A total of 1,116 clinically isolated strains belonging to Staphylococcus aureus (200), Staphylococcus epidermidis (200), Streptococcus pneumoniae (20), Escherchia coli (200), Klebsiella spp. (177), Serratia marcescens (22), Pseudomonas aeruginosa (224), Haemophilus influenzae (35) and Salmonella (38) from the Department of Infectious Diseases, La Sapienza(More)
An A-protein positive strain of Staphylococcus aureus was grown in varying concentrations of erythromycin, clindamycin and miocamycin at sub-MIC levels and incubated in purified human polymorphonuclear leukocytes (PMNs). The presence of A-protein produced resistance of the above strain to phagocytosis and killing by PMNs and a slight resistance to(More)
A comparative study of the in vitro activity of norfloxacin was performed versus that of aminoglycosides, pipemidic acid, tetracycline and chloramphenicol. These antibiotics are the most commonly used antimicrobial agents in the treatment of enteric and urinary tract infections. Results obtained with norfloxacin against Gram-negative isolates tested were(More)
We present the results of sensitivity of 191 Gram-negative bacteria towards the following antibiotics: aminoglycosides (amikacin, gentamicin, tobramycin, netilmicin), cephalosporines (moxalactam, cefotaxime, ceftazidime) and piperacilline obtained by agar diffusion method (Kirby-Bauer) versus automatic system MS 2 Abbott. Essential accord expressed in(More)
Twenty-four episodes of bacterial infections were identified over a 18 month period in 11 patients (8 with acquired immunodeficiency syndrome and 3 with AIDS related complex). Eight of the 11 infected patients were drug abusers and 3 homosexual people. Nosocomial bacterial infections were common in patients with AIDS and had high fatality rates.(More)
OBJECTIVES To evaluate the incidence of bacterial colonization in the throat and in urines of children admitted to a paediatric ward in the year 1994. To test the sensitivity of isolates on the most common antibiotics used in therapy. METHODS The investigation was carried out on a group of 270 children (125 male and 145 female), aged between 3 months and(More)
The authors have compared the antimicrobial resistance patterns and plasmid profiles of Gram-negative isolates in an intensive care unit over a 7-month period in order to identify epidemiologically related isolates. Bacterial plasmids were found to be valuable markers for the comparison of strains of nosocomial Gram-negative bacilli. Thirty-nine(More)
