selective medium for isolation of bacteroides nodosus.	the sensitivity of bacteroides nodosus, the causative agent of sheep foot rot, to 24 selected antimicrobial agents was tested. many contaminants ordinarily associated with foot rot lesions were sensitive to lincomycin, whereas b. nodosus demonstrated resistance to this antibiotic. a concentration of 1 microgram of lincomycin per ml of basal medium optimally inhibited contaminants while allowing growth of b. nodosus. the basal medium was eugon agar with 0.2% yeast extract and 10.0% defibrinated h ...	1977	908746
the role of various antigenic fractions of bacteroides nodosus in eliciting protection against foot-rot in vaccinated sheep.	sheep were vaccinated against foot-rot with various antigenic extracts of bacteroides nodosus and challenged to assess their resistance. the protective immunogen was shown to be a heat-labile, high molecular weight surface antigen which was removed by ultrafiltration and was either identical to or closely associated with the fimbriae of the organism. resistance appeared to be associated with the presence of a single high molecular precipitinogen distinct from the 0 antigen. agglutinating antibod ...	1978	625599
the occurrence, prevalence and transmission of bacteroides nodosus infection in cattle.	following reports of findings of ovine foot-rot flora in the feet of cattle, a study was undertaken to determine the prevalence of bacteroides nodosus infection in the apparently normal cattle population. we found that 34.5 to 74.2 per cent of the animals examined on different farms had b nodosus present in one or more feet. b nodosus was not the most prevalent bacterium observed in smears from cattle. other gram negative species including fusiformis necrophorus and many gram positive cocci and ...	1978	674842
effect of age, weight and adequacy of zinc intake on the balance between alkaline ribonuclease and ribonuclease inhibitor in various tissues of the rat.	1. deficiency of zinc inhibits growth and also increases the activity of alkaline ribonuclease in certain tissues of the rat (prasad & oberleas, 1973). zn could influence ribonuclease activity by direct effects on the enzyme or its natural inhibitor, or non-specifically as occurs when growth rate is affected by various other factors. these possibilities were studied. 2. alkaline ribonuclease was shown to be inhibited by zn in vitro, but the concentrations of zn required were so high that the enz ...	1978	415757

differentiation of bacteroides nodosus biotypes and colony variants in relation to their virulence and immunoprotective properties in sheep.	to obtain a wider definition of variation in the virulence of bacteroides nodosus and in the protective potency of b. nodosus vaccines, we made a comparison of the in vitro characteristics of isolates from clinical infections of sheep and cattle and of certain colony variants observed previously. three basic colony types were distinguished: papillate or beaded (b)-type colonies were produced by fresh isolates from advanced ovine foot rot; mucoid (m)-type colonies were formed by isolates from no ...	1981	7251146
effect of alum-precipitated or oil-adjuvant bacteroides nodosus vaccines on the resistance of sheep to experimental foot rot.	the feet of sheep which had been given two doses of oil adjuvant foot rot vaccine were completely resistant to direct challenge with a virulent homologous culture of bacteroides nodosus four weeks after vaccination, partially resistant after eight weeks but completely susceptible after 12 weeks. sheep given two doses of alum precipitated vaccine, or a dose of oil emulsion vaccine followed by a dose of alum precipitated vaccine, were resistant four weeks but not eight weeks later. foot rot in aff ...	1981	7244380
