Disease relevance of Antibiosis

• Methicillin-resistant coagulase-negative Staphylococcal osteomyelitis and its relationship to broad-spectrum oral antibiosis in a predominantly diabetic population [1].
• Additional information was gained regarding the interplay between alpha-haemolytic Streptococci (AHS) and otitis media (OM) pathogens by comparing the bacterial interference in broth with the interference activity studied using agar overlay methods [2].

High impact information on Antibiosis

• Several phenotypes have been identified as playing an important role in nodulation competitiveness including antibiosis, motility, speed of nodulation, cell-surface characteristics, and nodulation efficiency [3].
• Although their specific effects are difficult to quantitate, other LAB metabolic products such as hydrogen peroxide and diacetyl can also contribute to the overall antibiosis and preservative potential of these products [4].
• The results suggest that deltapsi drives zwittermicin A uptake, and that, unlike other antibiotics for which resistance maps in rpoB or rpoC, zwittermicin A does not cause the rapid cessation of DNA or RNA synthesis, suggesting a unique mechanism of antibiosis [5].
• The maysin and apimaysin QTLs were significant QTLs for corn earworm antibiosis, accounting for 14 [6].
• C-glycosyl flavones in maize silks confer resistance (i.e., antibiosis) to corn earworm (Helicoverpa zea [Boddie]) larvae and are distinguished by their B-ring substitutions, with maysin and apimaysin being the di- and monohydroxy B-ring forms, respectively [6].

Biological context of Antibiosis

• Effect of erythromycin on microbial antagonisms: a study in gnotobiotic mice associated with a human fecal flora [7].
• The sequence contains a 265-amino acid (aa) open reading frame and is 99.3% homologous to Arc1, another of the four electrophoretic variants with proven antibiosis characters [8].

Associations of Antibiosis with chemical compounds

• Bacterial interference with measurement of creatinine in stored plasma [9].
• Sixty-one patients were treated according to protocol II of the Paul-Ehrlich-Gesellschaft: initial application of gentamicin or tobramycin in combination with a cephalosporin or ureidopenicillin and, after 3 days, a potential change of antibiosis to be decided in case of nonresponse [10].
• We conclude that omeprazole-enhanced amoxicillin antibiosis is a simple and effective approach to the eradication of HP colonization [11].
• Antiamoebins, myrocin B and the basis of antifungal antibiosis in the coprophilous fungus Stilbella erythrocephala (syn. S. fimetaria) [12].
• Strains isolated from the rhizosphere grew over a wider temperature range, fixed nitrogen and produced IAA, did not produce proteases, displayed a wider antibiosis against the phytopathogenic fungi studied, did not adhere to human uroepithelial cells, promoted growth of C. sativus and only produced a hydroxamate-like siderophore [13].

Gene context of Antibiosis

• Evaluation of bacterial interference and beta-lactamase production in management of experimental infection with group A beta-hemolytic streptococci [14].
• H9, H10, and H11 are major dominant resistance genes in wheat, expressing antibiosis against Hessian fly [(Hf) Mayetiola destructor (Say)] larvae [15].
• Bacterial interference by similar micro-organisms was noted in 21 instances by 9 normal flora isolates that were recovered from 5 of the SP group, and in 63 instances by 26 isolates from 15 of the NSP group (p < 0.05) [16].
• Antagonists, G1 and G3 revealed strong antibiosis while T2 showed moderate effect [17].
• The mechanism of microbial antagonism was due to production and release of hydrogen peroxide under aerobic atmospheric conditions, which was neutralized through incorporation of bovine liver catalase into the solid assay medium [18].
