ABSTRACT: comparison of transcritonal profiling between the 3 strains; Neisseria meningitidis serogroup A (Z2491), Serogroup B (MC58), and Serogroup C (FAM18.
Project description:Comparison of transcriptional profiling between the 3 Neisseria meningitidis strains [serogroup A (Z2491), Serogroup B (MC58), and Serogroup C (FAM18)] and the 2 Neisseria gonorrhoeae strain (FA1090 and MS11).
Project description:transcription profiles of two groups each containing 5 strains of Disseminated gonorrhoeae (DG) and Undisseminated (superficial) gonorrhoeae (UG) were compared. An additional set of comparisons was done between 4 strains from group one Disseminated gonorrhoeae (DG) and another 4 strains from the same group.

Project description:Changing antigenic structure such as capsule polysaccharide is a common strategy for bacterial pathogen to evade host immune system. In this regard, the recent emergence of an invasive W:2a:P1.7-2,4 ST-11 strain in New Zealand, which is an uncommon pathogenic serogroup, was investigated for its genetic origins. Molecular typing of 103 meningococcal isolates with similar serotyping characteristics was undertaken to determine genetic relationships. Results indicated that the W:2a:P1.7-2,4 strain had emerged via capsule switching from an existing group C strain (C:2a:P1.7 2,4). Neither of the upstream and downstream sites of recombination could be elucidate but sequence analysis demonstrated that at least 45 kb of DNA was involved in the recombination event. This included the entire capsule gene cluster. Genomic DNA isolated from serogroup C strains (n=4) and serogroup W strains (n=4) were compared using Pan-neisseria DNA microarray.
Project description:Rhizobium leguminosaeum biovar viciae strain Rlv3841 was inoculated at either 10_3 CFU ot 10_8 CFU into the rhizosphere of 7 d old peas and the bacteria were harvested 7 days post inoculation. They were compared indircetly against a control of glucose ammonia grown laboratory cells.
Project description:Rhizobium leguminosarum biovar viciae strain Rlv3841 was grown for 7 d in the pea or alfalfa or sugarbeet rhizosphere (plants all 7 d old at inoculation) and compared against bacteria grown on glucose ammonia AMS medium in the laboratory.
Project description:Rhizobium leguminosarum biovar viciae strain Rlv3841 was inoculated into the rhizosphre of 7 d old peas and left for 1, 3 or 7 days before harvest and gene expression analysed.
Project description:Rhizobium leguminosarum biovar viciae strain Rlv3841 was grown for 7 days in the rhizosphere of either 7 day old pea, alfalfa or sugarbeet before being harvested.
