Clostridium difficile is a Gram-positive bacterium commonly found in health care and long-term-care facilities and is the most common cause of antibiotic-associated diarrhea. Rapid detection of this bacterium can assist physicians in implementing contact precautions and appropriate antibiotic therapy in a timely manner. The purpose of this study was to compare the clinical performance of the Qu...

The antibiotic cerulenin causes the immediate cessation of phospholipid biosynthesis in both chemoheterotrophic and photoheterotrophic cultures of Rhodopseudomonas sphaeroides. Macromolecule biosynthesis in photoheterotrophic cells was unaffected by cerulenin for the first 2 h after antibiotic addition and then continued at a reduced rate for an additional 8 h. In contrast, macromolecule biosyn...

In order to evaluate the importance of suppuration, persistent infection, and scar formation in the evolution of Escherichia coli chronic pyelonephritis, we treated rats with different antibiotic regimens at different stages of the disease. The results show that (a) if acute suppurative pyelonephritis is aborted with early antibiotic therapy, chronic pyelonephritis is prevented; (b) chronic pye...

BACKGROUND AND PURPOSE The purpose of this study was to review the imaging findings of nasal septal abscess in 2 patients with immunosuppression. MATERIALS AND METHODS Two patients with immunosuppression were identified as having a nasal septal abscess, and correlative CT imaging in both patients was evaluated. RESULTS The characteristic radiographic appearance of a nasal septal abscess inc...

Purpose. To report one case of corneal antibiotic deposition after ciprofloxacin administration in Laser Assisted Subepithelial Keratomileusis (LASEK). Methods. One case of post-LASEK treatment resulted in corneal precipitates and poor wound healing. Debris was analyzed with dark field microscopy and placed on a blood-agar plate seeded with a susceptible stain of Staphylococcus aureus (ATCC 292...

Escherichia coli is being one of the common microbial flora of gastrointestinal and respiratory tracts of poultry but may become pathogenic to both. Antibiotic treatment is considered the most important issue that promotes the emergence, selection and deploying of antibiotic-resistant microorganisms in veterinary medicine. With the increase of resistant to antibiotics, many researchers have tri...

BACKGROUND Florid infection and osteomyelitis of the forefoot in patients with diabetic neuropathy often requires minor amputation, with risk of subsequent reulceration, reamputation, and patient dissatisfaction. We investigated use of an antibiotic-impregnated cement spacer (ACS) to release antibiotic locally to resolve residual infection and to fill the cavity created by debridement. METHOD...

Despite resolution of the objective manifestations of Lyme disease after antibiotic treatment, a minority of patients have fatigue, musculoskeletal pain, and/or difficulties with concentration or short-term memory of uncertain etiology; these are called post-Lyme disease symptoms or, in more severe cases, post-Lyme disease syndrome or "chronic Lyme disease." Several recent studies in which Borr...
