The antibiotic described was found to show antimicrobial activity against gram-negative bacteria, gram-positive bacteria, and pathogenic fungi. (wikipedia.org)
from Osaka University studied a strain of S. antibioticus that produced a molecule with the ability to induce the organism Streptomyces virginiae to produce the antibiotic Virginiamycin. (wikipedia.org)
Biological Activity： Virginiamycin S1 is a cyclic hexadepsipeptide antibiotic, inhibits bacterial protein synthesis at the level of aminoacyl-tRNA binding and peptide bond formation. (epigenetics-modulation-frontier.com)
Similarly, 9 reports were collected allowing 11 comparisons of positive control (antibiotic supplemented) diets and Actigen ® supplemented diets. (scialert.net)
Compared with positive control (antibiotic) results, dietary Actigen ® at average inclusion rates by phases of 535/331/238 g/tonne (n = 11) and broiler age of 43.64 days (n = 11) non significantly changed body weight by +0.016 kg (+0.62%), feed conversion ratio or feed/gain ratio by -0.003 (-0.17%) and mortality % by +0.57 (+7.97% relative to positive control).

The investigation team focused on use of a growth-promoting antibiotic, called virginiamycin, in poultry. (sciencedaily.com)
Virginiamycin is closely related to quinupristin-dalfopristin, an antibiotic licensed to treat patients with serious, antibiotic-resistant infections. (sciencedaily.com)
These results indicate that virginiamycin use in poultry leads to transfer of antibiotic resistance genes to human gut bacteria through the food supply and they provide additional evidence that use of growth promoters in animals may have long-term consequences for human health. (sciencedaily.com)
After exposure to virginiamycin, E. faecium from conventional poultry and from patients who consumed poultry became resistant to Synercid more often than E. faecium from vegetarians or from antibiotic-free poultry. (sciencedaily.com)
Based on results, 0.75 and 1% AP had positive effect on growth performance, immunity and small intestine health of broilers and with regards to restriction on the use of antibiotic in broiler ration, AP can be used to improve growth performance and immunity of broilers. (ac.ir)
We identified 317 mcr positive and 745 azithromycin resistance genes positive Salmonella isolates out of 7,997 isolates. (bvsalud.org)
Bactericidal2
Actinomycin B displayed little bacteriostatic activity but was shown to be highly bactericidal (bacteria killing), particularly towards gram-positive bacteria. (wikipedia.org)
Virginiamycin S1 belongs to the type B compounds in the streptogramin family and is produced by Streptomyces virginiae , shows a strong bactericidal activity against a wide range of Gram-positive bacteria. (epigenetics-modulation-frontier.com)
Theseare active against both Gram-positive and Gram-negative organisms. (microbiologyinfo.com)
Type1
All 3 previously reported cases of CA-MRSA infection in Italy were caused by type IV SCCmec, PVL-positive strains, none of which, however, belonged to the ST80 clonal lineage that predominates in Europe (7). (marynmckenna.com)
Effects1
The objectives were to evaluate the effects of monensin and virginiamycin, alone or combined, on supplemented Nellore cattle grazing tropical grass during the rainy season. (scielo.br)
Effective1
For example, glycopeptides and bacitracin are only effective against Gram-positive bacteria, whereas polymixins are usually only effective against Gram negative bacteria. (microbiologyinfo.com)
Activity1
They have limited activity and are primarily only useful against particular species of microorganisms either Gram positive or Gram negative. (microbiologyinfo.com)

Quinupristin1
Quinupristin/dalfopristin 7.5 mg/kg 8- or 12-hourly also achieved similar clinical success rates to comparator agents in patients with presumed gram-positive complicated skin and skin structure infections or nosocomial pneumonia (administered in combination with aztreoman) in 3 large multicentre randomised trials. (nih.gov)
Bacitracin1
Among the antibiotics used are ampicillin, bacitracin, erythromycin, lincomycin, virginiamycin, and tetracycline ( Food and Drug Administration 2004 ), some of which are important in human clinical medicine. (nih.gov)

A total of 137 presumptive Enterococcus isolates were identified to species level using standard biochemical tests and analyzed for resistance to erythromycin, clindamycin, virginiamycin, tetracycline, and vancomycin using the agar dilution method. (nih.gov)
Enterococcus2
From 125 separate cloacal cultures from three turkey flocks fed virginiamycin, 104 Enterococcus faecium and 186 Enterococcus faecalis isolates were obtained. (nih.gov)
The combination has inhibitory activity against a broad range of gram-positive bacteria including methicillin-resistant staphylococci, vancomycin-resistant Enterococcus faecium (VREF), drug-resistant Streptococcus pneumoniae, other streptococci, Clostridium perfringens and Peptostreptococcus spp. (nih.gov)
