INTRODUCTION The presence of postoperative seromadesis is common, corresponding to the presence of serum in the subcutaneous tissue post a surgical event. Erythromycin has been reported as sclerosing, although not in orthopedic surgery. We report a case of erythromycin seromadesis in orthopedic surgery. CASE PRESENTATION We present a case of a 63-year-old woman having undergone femoral prosth...

9-O-Glycosyloxime derivatives of erythromycin A have been synthesized and their in vitro antibacterial activity compared with that of erythromycin A (1). This new class of macrolide antibiotics showed reduced antibacterial spectrum. However, some derivatives were as or more active than erythromycin A (1) against strains, responsible for respiratory track infections, such as Haemophilus influenz...

OBJECTIVES Tegaserod may enhance upper gut transit, but, its prokinetic effects on antral/small bowel motility and how this compares with erythromycin is unknown. We prospectively assessed and compared the effects of tegaserod and erythromycin on upper gut motility. METHODS In an open label, non-crossover study, 22 patients (M/F=4/18; mean age=37 years) with symptoms of upper gut dysmotility ...

AIM The aims of the present study were to determine the antibiotic susceptibility profils with particular emphasis on susceptible or resistant strains to macrolides and lincosamids antibiotics and to determine possible antibiotic resistance mechanisms occurring in group B streptococci (GBS) strains using PCR assay and disk diffusion method. METHODS A total of 62 clinical GBS strains were inve...

BACKGROUND Erythromycin is available as the free base, ethylsuccinate, estolate, stearate, gluceptate, and lactobionate derivatives. When given orally erythromycin and its derivatives except the estolate are inactivated to some extent by the gastric acid and poor absorption may result. OBJECTIVES To establish whether delayed release erythromycin tablets meet the bioequivalent requirement for ...

OBJECTIVES To evaluate the effectiveness of high-dose erythromycin to treat feeding intolerance in preterm infants predominantly fed milk formula. DESIGN This study is a prospective randomized controlled trial on 60 premature infants suffering from feeding intolerance. Thirty infants were given oral erythromycin ethylsuccinate at a dose of 50 mg/kg/day for 10 days or until they reached full e...

Cethromycin is a ketolide with in vitro activity against macrolide-sensitive and -resistant strains of Streptococcus pneumoniae. We compared its in vivo efficacy to erythromycin in a mouse model of acute pneumonia induced by two virulent clinical strains: a serotype 3 susceptible strain (P-4241) (MICs: erythromycin, 0.03 microg/ml; cethromycin, 0.015 microg/ml) and a serotype 1 strain resistant...

Saccharopolyspora erythraea makes erythromycin, an antibiotic commonly used in human medicine. Unusually, the erythromycin biosynthetic (ery) cluster lacks a pathway-specific regulatory gene. We isolated a transcriptional regulator of the ery biosynthetic genes from S. erythraea and found that this protein appears to directly link morphological changes caused by impending starvation to the synt...

The antibiotic erythromycin has limited efficacy and bioavailability due to its instability and conversion under acidic conditions via an intramolecular dehydration reaction. To improve the stability of erythromycin, several analogs have been developed-such as azithromycin and clarithromycin-which decrease the rate of intramolecular dehydration. We set out to build upon this prior work by devel...

Background—The aim of this study was to compare neutrophil migration in cystic fibrosis (CF) and non-CF populations and to investigate the eVect of erythromycin on directed migration of neutrophils (PMNs) in CF. Methods—PMNs were isolated and their migratory capacity in response to interleukin-8 (IL-8) or f-Met-Leu-Phe (fMLP) in the presence or absence of erythromycin (1–100 μg/ml) was assessed...
