Lincosamides are a class of antibiotics used both in clinical and veterinary practice for a wide range of pathogens. This group of drugs inhibits the activity of the bacterial ribosome by binding to the 23S RNA of the large ribosomal subunit and blocking protein synthesis. Currently, three X-ray structures of the ribosome in complex with clindamycin are available in the Protein Data Bank, which...

The treatment of experimental gas gangrene caused by Clostridium perfringens was investigated by using combinations of antimicrobial agents. This study demonstrated that rifampin, penicillin, metronidazole, and clindamycin were all bactericidal against standard inocula (10(5) to 10(6) CFU). These antimicrobial agents were then administered to mice beginning 30 min after intramuscular injection ...

Abstract In the present study, antibiotic resistance profiles and biofilm forming abilities of 9 Listeria monocytogenes isolates obtained from out 30 retail meat samples were determined, effect commercial white vinegar on these virulence factors in exposed to subMIC concentrations investigated. All found be resistant cefotixin oxacillin, 8 (26.6%) clindamycin, 1 isolate (3.3%) rifampicin, was s...

Clindamycin, a semi-synthetic antibiotic of the lincomycin family, at a dose of 450 mg eight-hourly for three days in adults cured five out of 10 patients moderately ill with chloroquine-resistant falciparum malaria. Combination therapy with full-dose quinine and clindamycin for three days cured all four patients so treated who were followed up, and with half dosage three out of five patients w...

Bacterial counts were carried out on the faeces of 160 patients receiving clindamycin or lincomycin treatment for bacterial infections. In all the patients the total bacteroides count was significantly reduced while strains of Enterobacteriaciae, yeasts, and streptococci were correspondingly increased. Severe diarrhoea developed in 25 (16%) patients, but this could not be related to a change in...

The comparative in vitro activity of RU 64004 (also known as HMR 3004), a new ketolide antibiotic, was tested by agar dilution against approximately 500 gram-positive organisms, including multiply resistant enterococci, streptococci, and staphylococci. All streptococci were inhibited by < or = 1 microg of RU 64004 per ml. The ketolide was more potent than other macrolides against erythromycin A...

We examined the resistance phenotype and the genetic basis of lincosamide modification in 25 clinical isolates of Staphylococcus spp. inactivating lincomycin and clindamycin. The strains were resistant to high levels of lincomycin but remained susceptible to clindamycin. However, MBCs and inoculum effects showed that the activity of clindamycin was impaired. The distribution in these strains of...

Staphylococcus haemolyticus BM4610 was resistant to high levels of lincomycin and susceptible to macrolides, clindamycin, and streptogramins. This resistance phenotype, not previously reported for a human clinical isolate, was due to inactivation of the antibiotic. The gene conferring resistance to lincomycin in strain BM4610 was carried by a 2.5-kilobase plasmid, pIP855, which was cloned in Es...
