three experiments were carried out for isolation of bacteriophage against growth reducing enterococcus faecalis and evaluation of its efficacy to control enterococci colonization in intestine of japanese quails. in experiment one, 60 enterococci spp were isolated from gastrointestinal contents of adult quails, which among them seven isolates were selected based on preliminary tests. in experime...

The antibacterial effects of telavancin, vancomycin, and teicoplanin against six Staphylococcus aureus strains (1 methicillin-susceptible S. aureus [MSSA] strain, 4 methicillin-resistant S. aureus [MRSA] strains, and 1 vancomycin-intermediate S. aureus [VISA] strain) and three Enterococcus sp. strains (1 Enterococcus faecalis strain, 1 Enterococcus faecium strain, and 1 vancomycin-resistant E. ...

CONTEXT A change in the epidemiology of pathogens causing serious bacterial infection (SBI) has been noted since original recommendations were made for the empirical antibiotic choices for young infants with fever. OBJECTIVE To assess the prevalence of SBI caused by Listeria monocytogenes and Enterococcus species. DATA SOURCES A literature search was conducted on keywords related to SBI, L....

Enterococcus faecalis and Enterococcus faecium are among the leading causes of hospital-acquired infections. Reliable and quick identification of E. faecalis and E. faecium is important for accurate treatment and understanding their role in the pathogenesis of infections. Fluorescent in situ hybridization (FISH) of whole bacterial cells with oligonucleotides targeted at the 16S rRNA molecule le...

Using six Enterococcus faecalis and five Enterococcus faecium strains, the ketolide ABT-773 (ABT), now known as cethromycin, was found to have in vivo efficacy against both erythromycin (ERY)-susceptible (Ery(s)) and -intermediate (Ery(i)) enterococci (ABT 50% protective doses [PD(50)s], 0.5 to 4.1 and 10.3 to 16.2 mg/kg of body weight, respectively). Against four highly Ery-resistant (Ery(r)) ...

BACKGROUND AND AIMS Enterococci are among resistant microorganisms to antibiotics and are responsible for some of acute gingival infections. This study aimed at molecular evaluation of gentamicin-resistant enterococcus species and determining the resistance genes. MATERIALS AND METHODS Clinical samples were cultured on BHI medium and enterococci were isolated by specific methods and antibiogr...

Thirty-seven clinical isolates of Enterococcus gallinarum and Enterococcus casseliflavus and three type or reference strains of the species were studied with respect to vancomycin susceptibility and key identification characteristics. With the exception of one clinical isolate of E. casseliflavus (MIC, 4 micrograms/ml), MICs of vancomycin were 8 to 32 micrograms/ml. The type strain of E. gallin...

The emergence of clinical enterococcal isolates resistant to both ampicillin and vancomycin is a cause of great concern, as there are few therapeutic alternatives for treatment of infections caused by such organisms. We evaluated the effects of the combination of ampicillin with vancomycin against vancomycin-resistant clinical enterococcal isolates. Using both the checkerboard technique and tim...

The minimal inhibitory concentration of lincomycin and clindamycin for a large number of strains from multiple serogroups of streptococci was determined. The median minimal inhibitory concentration for streptococci from groups A, B, C, F, G, H, L, and M and nongroupable organisms ranged from 0.02 to 0.39 mug of lincomycin per ml and from </=0.01 to 0.09 mug of clindamycin per ml. Among the grou...
