| restriction endonuclease from haemophilus gallinarum (hgai) cleaves polyoma dna at four locations. | a restriction endonuclease obtained from haemophilus gallinarum (hgai) cleaves polyoma dna at four specific sites. using the ecori, hindiii, and hpaii endonuclease restriction sites as reference, the four hgai cleavage sites were mapped at 0.02, 0.14, 0.27, and 0.48 fractional lengths, clockwise, from the single ecori cleavage site. | 1976 | 178910 |
| [differentiation of haemophilus strains isolated from chickens. iv. studies on the dissociation of haemophilus paragallinarum]. | bacteria of 2 phenotypic forms of one strain of haemophilus paragallinarum were morphologically, culturally, biochemically and serologically investigated. on transparent solid media bacteria of the m variant (mucoid) were capsulated and showed iridescence in oblique transmitted light throughout the first 8-14 hours of incubation. iridescence disappeared completely after 36 hours incubation. bacteria of this variant formed stable homogeneous suspensions in 0.15 m nacl and an homogeneous cloudines ... | 1976 | 18777329 |
| infectious coryza: in vivo growth of haemophilus gallinarum as a determinant for cross protection. | four strains of haemophilus gallinarum representing 3 immunotypes were used in exposure and challenge exposure studies to determine if in vivo growth of the organism would induce cross protection in chickens. birds which recovered from infection to 1 immunotype were refractory to reinfection with the heterologous immunotype. in contrast, in vitro-produced bacterins produced immunotype-specific protection. | 1977 | 931141 |
| cleavage specificity of the restriction endonuclease isolated from haemophilus gallinarum (hga i). | the nucleotide sequences in the replicative form (duplex) of phix174 dna around six sites cut by hga i, a restriction endonuclease from haemophilus gallinarum, have been compared. the enzyme produces a staggered cleavage resulting in a pentanucleotide 5'-terminal extension. the sequences within and immediately surrounding the pentanucleotide cleavage site have no obvious relationship. however, the sequence 5'-g-a-c-g-c-3' 3'-c-t-g-c-g-5' occurs five nucleotide pairs to the left of the cut in th ... | 1977 | 269384 |
| serologic response to haemophilus gallinarum in artifically infected and vaccinated chickens. | serologic responses to haemophilus gallinarum (hg) were compared in chickens artifically inoculated with living hg and vaccinated with hg bacterin, using tube agglutination (agg), hemagglutination-inhibition (hi), and agar-gel precipitation (agp) tests. infected and vaccinated chickens differed markedly, as did infection routes early after treatment. hi response was delayed and lower in chickens infected intranasally than in vaccinated chickens. both agg and agp responses peaked sooner than hi. ... | 1977 | 402906 |
| infectious coryza: cross-protection studies, using seven strains of haemophilus gallinarum. | bacterins prepared from 7 strains of haemophilus gallinarum were used to immunized chickens for cross-protection studies. three distinct immunotypes were distinguished. slight protection between immunotypes was evident for some strains. airsacculitis could be prevented by use of these bacterins; however, prevention was related to immunotype specificity. hyaluronic acid found in 2 strains rendered them inagglutinable in homologous antiserums. treatment with hyaluronidase rendered them agglutinabl ... | 1977 | 931140 |
| experimental coryza in broiler chickens. i. effects of vaccination with haemophilus gallinarum bacterin and its components on weight gains and resistance to infection. | effects of a haemophilus gallinarum bacterin and its components were studied in young broiler chickens. when the bacterin was administered subcutaneously in the dorsal neck region at 2 weeks of age, no significant differences in weight gains of vaccinated and control birds were detected at eight weeks of age. in four groups vaccinated at 1, 2, 3, or 4 weeks of age and challenged with virulent haemophilus organisms 3 weeks later, the incidence of clinical signs was 30% in the vaccinates and 60% i ... | 1977 | 907579 |

| intranasal inoculation of chickens with encapsulated or nonencapsulated variants of haemophilus paragallinarum: electron microscopic evaluation of the nasal mucosa. | chickens were inoculated intranasally with encapsulated or nonencapsulated strains of haemophilus paragallinarum. the nasal mucosa of the chickens were examined, using scanning and transmission electron microscopy. in chickens given the encapsulated variant, marked loss of cilia and microvilli, infiltration of leukocytes, and deposition of a mucopurulent substance were seen on the surface of the nasal mucosa; the number of microvillous cells were markedly increased, and infiltration of mast cell ... | 1985 | 4073645 |
| the resistance to anti-microbial agents of bacteria isolated from pathological conditions of birds in victoria, 1978 to 1983. | the resistance to anti-microbial agents of bacteria isolated from pathological conditions of birds in victoria, 1978 to 1983, was determined for isolates of escherichia coli, salmonella species, staphylococcus aureus, pasteurella multocida, p. anatipestifer, yersinia pseudotuberculosis and haemophilus paragallinarum. the isolates of e. coli had a high prevalence of resistance to tetracycline and sulphonamides, and a lower prevalence of resistance to furazolidone and sulphamethoxazole-trimethopri ... | 1985 | 3914884 |
| an evaluation of commercial discs for the determination of the growth factor requirements of avian haemophili. | the ability of 2 brands of growth factor discs (oxoid and mast) to identify correctly the growth factor requirements of 41 isolates of haemophilus paragallinarum and 17 isolates of h. avium was evaluated. the percentage of isolates correctly identified as requiring v factor varied with both the brand of the disc and the medium used. on basic nutrient media both brands gave low percentages of correct results: on isosensitest agar (oxoid) the oxoid discs gave 26% and the mast discs 24% while on he ... | 1985 | 3984205 |
| partial purification and characterization of type i dna topoisomerase from bacillus stearothermophilus. | type i dna topoisomerase was partially purified from bacillus stearothermophilus by ammonium sulfate precipitation and column chromatographies on phosphocellulose, deae-cellulose and heparin-agarose. on heparin-agarose chromatography, topoisomerase i activity was separated into three fractions (designated fractions a, b, and c). each fraction was further subjected to gel filtration on sephacryl s-200. from electrophoretic analysis on polyacrylamide gel, fraction a was found to contain two enzyme ... | 1985 | 2991208 |
| genetic and phenotypic comparison of three new avian haemophilus-like taxa and of haemophilus paragallinarum biberstein and white 1969 with other members of the family pasteurellaceae pohl 1981. | in the course of post-mortem bacteriological examinations, several previously unreported bacterial strains were isolated from budgerigars, pigeons, kestrels, and a goose. they have been separated into three distinct collectives according to their cultural, morphological, and biochemical characteristics. since they require v factors, they were tentatively assigned to the genus haemophilus winslow et al. 1917. this preliminary classification was checked by determination of guanine + cytosine conte ... | 1985 | 4074234 |
| taxonomy of some recently described avian pasteurella/actinobacillus-like organisms as indicated by deoxyribonucleic acid relatedness. | members of the family pasteurellaceae pohl 1981 are frequently encountered in birds as parasites or pathogens, e.g. the well-known species pasteurella multocida, pasteurella gallinarum, haemophilus paragallinarum, and three species containing strains that had been previously classified as "haemophilus avium"(pasteurella avium, pasteurella volantium, and an unnamed pasteurella species defined by mutters et al., 1985). a variety of additional taxa which had been tentatively assigned to the family ... | 1985 | 18766923 |
| comparison of adjuvants for an inactivated infectious coryza vaccine. | differently formulated inactivated infectious coryza vaccines were administered to 6-week-old chickens as a single dose of 10(8) colony-forming units of haemophilus paragallinarum hp31. after 3 weeks, all chickens were challenged by intrasinus inoculation of hp31. two vaccines, one containing an aluminum-hydroxide adjuvant and the other a combined aluminum-hydroxide + mineral-oil adjuvant, gave the best protection (means of 80% and 90%, respectively). two vaccines that contained mineral oil as t ... | 1987 | 3579795 |
| further efficacy studies on inactivated, aluminum-hydroxide-adsorbed vaccines against infectious coryza. | specific-pathogen-free chickens were given infectious coryza vaccines containing inactivated cells of haemophilus paragallinarum adsorbed onto an aluminum-hydroxide gel. the vaccines were protective when given subcutaneously or intramuscularly but not when given intranasally. vaccines prepared with two different commercial brands of aluminum-hydroxide gel gave similar protection. vaccines in which the inactivating agent was thimerosal were more protective than similar vaccines in which the inact ... | 1987 | 2960312 |
