BACKGROUND AND PURPOSE In order to reduce the turnaround time for laboratory diagnosis of bacteremia, the efficacy of identification and antimicrobial susceptibility testing using samples taken directly from positive BacT/ALERT standard aerobic and standard anaerobic blood culture bottles was evaluated. METHODS 160 positive blood culture bottles were examined and incubated at 35 degrees C in ...

AIMS To study the distribution and shifting trends of bacterial keratitis. METHODS The data of 2220 corneal isolates from 1 January 1989 to 31 December 1998 were reviewed retrospectively. RESULTS Positive culture was recovered in 490 isolates. Gram positive cocci and Gram negative bacilli represented 51% and 39.4%, respectively. Pseudomonas aeruginosa was the most common pathogen (32.2%). A...

Gingivitis is an inflammatory destructive disease mainly caused by microbial plaques. Gram-positive and gram-negative bacilli or cocci have been isolated from dental plaque and gingivitis. This study was going to isolate and characterize the pathogenic bacteria from gingival of 100 patients with oral gingivitis. Enriched and specific media used for isolation of bacteria. Identification of isola...

An 18-week-old female breeding Yorkshire pig displayed symptoms of astasia and subsequently died. Histologically, severe disseminated suppurative meningoencephalomyelitis was detected, as were numerous myocardial microabscesses. Gram-positive cocci were detected in these suppurative lesions, and these cocci reacted with an antibody against Streptococcus C group species. Gram-positive cocci were...

A procedure was developed for 4-h identification of bacteria from blood culture. From a turbid blood culture bottle a 10- to 15-ml aliquot was drawn off and centrifuged. The pellet was utilized to inoculate a series of enzymatic and physiologic reactions. Three hundred eight positive blood cultures were tested including 222 strains of Enterobacteriaceae, 40 strains of facultative grampositive c...

The in vitro activity of minocycline against 1,028 bacterial strains was determined in parallel in Mueller Hinton Agar and Trypticase Soy Agar. The broad antibacterial effect of minocycline against gram-positive cocci and gram-negative bacilli is confirmed. Minimal inhibitory concentrations for gram-positive bacteria in Mueller Hinton Agar were at least twofold less than in Trypticase Soy Agar....

The in vitro activities of ABT-773 were evaluated against 324 strains of gram-positive bacteria, including multidrug-resistant Staphylococcus spp. and Enterococcus spp. ABT-773 had lower MIC ranges, MICs at which 50% of isolates are inhibited (MIC(50)s), and MIC(90)s than erythromycin or clindamycin for almost all isolates tested. The MICs of ABT-773 were also lower than those of quinupristin-d...

The in-vitro activities of the quinolones Bay 12-8039, gatifloxacin (AM 1155), trovafloxacin, clinafloxacin, levofloxacin and ciprofloxacin were compared. Gram-positive cocci were most susceptible to Bay 12-8039, clinafloxacin and trovafloxacin; Enterobacteriaceae and fastidious organisms were most susceptible to clinafloxacin [corrected]; Pseudomonas spp. were most susceptible to clinafloxacin...
