experimentally induced infectious bovine keratoconjunctivitis: relationship of vaccination schedule to protection against exposure with homologous moraxella bovis culture.calves were intramuscularly vaccinated with a formalin-killed moraxella bovis culture. they were given 3 doses of the vaccinal culture at 3 different intervals between injections, as follows: 7-day intervals (group i), 14-day intervals (group ii), an21-day intervals (group iii); 14 days after the 3rd vaccinal dose was given, calves in all groups were challenge exposed to virulent homologous m bovis. the challenge bacterium became established in all (100%) of the control (group iv, n equals 8) an ...1975803804
in-vitro effect of edta-tris-lysozyme solutions on selected pathogenic bacteria.the in-vitro effect of edta-tris-lysozyme solution on 16 pathogenic bacteria of medical or veterinary importance was determined. marked decreases in bacterial count occurred with pseudomonas aeruginosa, escherichia coli, moraxella osloensis and campylobacter fetus, and smaller decreses with salmonella typhimurium, shigella boydii, aeromonas hydrophila, proteus mirabilis, listeria monocytogenes and erysipelothrix insidiosa. the test solution had no effect on klebsiella ozaenae, brucella canis, co ...1975805241
isolation of listeria monocytogenes type 04 from cases of keratoconjunctivitis in cattle and sheep.keratoconjunctivitis in cattle and sheep is usually recognized as a summer problem. the infective agency usually isolated from cattle is moraxella bovis. in sheep neisseria ovis and rickettsia (colesiota) conjunctivae are expected to be found. this report describes isolations of listeria monocytogenes from eye inflammations in housed cattle and sheep.1975806058
[antibiosis shown by a strain of byssochlamys nivea westling, 1909. ii. activity spectrum].a strain of byssochlamys nivea cultivated in a liquid medium (saccharose: 50 g: nano3: 2 g; kh2po4: 1 g; kcl: 0.5 g; mgso4, 7h2o: 0.5 g; water to 1000 ml) produces, at 24 degrees c, an antibiotic substance which appears after several days of growth (10-12 days). among 43 strains of bacteria gram (minus) belonging to 10 genera none was resistant. the most was susceptible, save pseudomonas aeruginosa, serratia marcescens, moraxella glucidolytica. on the the great bulk of the bacteria (gram +) test ...1975806806
[bacteriostatic and bacteriacidal activity of hydroxy-9 ellipticine in vitro].9-hydroxy-ellipticine shows a clear effect against bacterial development. this effect depends essentially upon the bacterial species. two groups can be differentiated: group i with resisting species composed by negative gram bacilli (enterobacteria and pseudomonas); group ii with sensitive species formed by coccus, positive gram bacilli, mycobacterium tuberculosis and anaerobes.1975807356

prevalence of gram-negative rods in the normal pharyngeal flora.we obtained throat cultures from 100 randomly selected people free from any chronic upper or lower respiratory disease who did not work in a hospital and who had not experienced any acute illness or received any antibacterial therapy in the 4 weeks preceding culture. eighteen percent harbored either a species of enterobacteriaceae or pseudomonas aeruginosa in their pharynx. in all cases, colony counts were low, the majority being detected in broth media selective for gram-negative rods. there we ...1975810051
gas chromatography of bacterial whole cell methanolysates. vii. fatty acid composition of acinetobacter in relation to the taxonomy of neisseriaceae.the cellular fatty acids of seventeen acinetobacter strains were determined. most acids identified were previously found in neisseriae and moraxellae. specific for acinetobacter was 2-hydroxydodecanoid acid and a few minor unidentified components. the fatty acid data were analysed by numerical methods and compared with previous results obtained for neisseriae and moraxellae. the findings were consistent with genetic evidence for some affinities of genus acinetobacter to genus moraxella and "fals ...1975812336
[moraxella osloensis as pathogen in septicemia (author's transl)].a case of septicemia caused by moraxella osloensis is described. a 4-year old girl fell ill with symptoms similar to those described in cases of septicemia caused by neisseria meningitidis. two days after the commencement of treatment with penicillins, however, moraxella osloensis could be isolated from cerebral fluid, which contained only a small number of cells. it is assumed that the delayed recovery of the child was directly related to the diminished susceptibility of this moraxella strain t ...1976824208
bacteriocin production by neisseria gonorrhoeae.seventeen apparently unrelated isolates of neisseria gonorrhoeae out of 2,123 tested produced a diffusible growth-inhibitory substance against other gonococci. the inhibitor was destroyed by trypsin, not blocked by bovine serum albumin, and not soluble in chloroform-methanol; each isolate was resistant to the inhibitor it produced. thus, the substance differs from previously described gonococcal inhibitors, and since it fits the description of a bacteriocin we designated it gonocin. the use of g ...1976825028
suceptibility of aminoglycoside-resistant gram-negative bacilli to amikacin: delineation of individual resistance patterns.gram-negative bacilli isolated from clinical specimens submitted for culture in two paris hospitals during 1974 were studied for susceptibility to six currently used aminoglycosides: kanamycin, neomycin, paromomycin, lividomycin, gentamicin, and tobramycin. resistance patterns of strains of various species including those of enterobacteriaceae, pseudomonas, and moraxella were determined, and the strains were grouped into eight resistance "phenotypes." in comparative studies of 807 strains belong ...1976825587

relationship of neisseria elongata subsp. glycolytica to other members of the family neisseriaceae.neisseria elongata subsp. glycolytica strain 6171/75 is closely similar to the type strain of n. elongata, m2, as regards dna base composition, fatty acid content and electrophoretic mobility of two glutamate dehydrogenases, one of which showed a reaction of identity with the corresponding enzyme from m2 in double immunodiffusion in agar. the strain showed genetic homologies with strain m2 in genetic transformation at a level suggesting species identity, and with n. meningitidis at a lower level ...1977842351
marginal corneal ulcer due to beta-streptococcus.a 72-year-old woman with a low-grade nasolacrimal duct obstruction developed a hyperacute conjunctivitis caused by beta-hemolytic streptococci. this condition has been termed "conjunctivitis of morax". an unusual feature consisting of a large, marginal furrow-like corneal ulcer was noted associated with a plastic iritis. the condition improved with the use of topical erythromycin, irrigation of the lacrimal sac with aqueous penicillin and oral penicillin. we believe that the marginal corneal ulc ...1977843277
genetic transformation assays for identification of strains of moraxella urethralis.studies of 31 strains of moraxella urethralis have shown that 20 of them are competent for genetic transformation. this finding has led to the development of transformation assays for identification of newly isolated strains of this organism. crude deoxyribonucleic acid (dna) samples from all strains of m. urethralis readily transform auxotrophic mutants of competent strains to prototrophy, whereas dna samples from unrelated bacteria such as acinetobacter, moraxella, and neisseria species unifor ...1977845247
