Streptomycin as a selective agent to facilitate recovery and isolation of introduced and indigenous Sphingomonas from environmental samples.
culturable Sphingomonas from soils. All 29 previously described bacterial strains belonging to 17 different Sphingomonas species were able to grow on mineral media containing 200 microg ml(-1) streptomycin, ...
Evaluation of tests for antibodies against bovine herpesvirus 1 performed in national reference laboratories in Europe.
prepared, lyophilised and distributed by 1 laboratory to 12 reference laboratories in Europe. The serum sets contained the three European bovine herpesvirus 1 (BHV1) reference serum samples (EU1, EU2 and ...
Conditional expression of type I interferon-induced bovine Mx1 GTPase in a stable transgenic vero cell line interferes with replication of vesicular stomatitis virus.
We validated a double transgenic Vero cell clone in which the bovine Mx1 reference allele is placed under control of the human cytomegalovirus (CMV) enhancer-promoter sequence containing elements from ...
Assessment of the clinical and virological protection provided by a commercial inactivated bovine viral diarrhoea virus genotype 1 vaccine against a BVDV genotype 2 challenge.
carried out to determine the cross-protective efficacy of a commercial inactivated vaccine containing a BVDV-1 strain. A group of five BVDV-free calves was vaccinated twice and a second group of five calves ...
Tetraponera ants have gut symbionts related to nitrogen-fixing root-nodule bacteria.
examined the ultrastructure of these bacteria and have amplified, cloned and sequenced ribosomal RNA-encoding genes, showing that the ant pouch contains a series of close relatives of Flavobacteria and ...
Use of the pAL5000 replicon in PAH-degrading mycobacteria: application for strain labelling and promoter probing.
pyrene, respectively, were successfully electroporated with pAL5000-based plasmids containing the green fluorescent protein (gfp) gene of Aequoria victoria under the control of the hsp60 promoter of ...
Specific bovine antibody response against a new recombinant Cryptosporidium parvum antigen containing 4 zinc-finger motifs.
Publication Type: Peer reviewed scientific article Authors: De Graaf, Dirk C; De Coninck, Hans; Petry, Franz; Eeckhout, Ilka B; Johan Peeters Source: Korean J Parasitol, Volume 40, Issue 1, p.59-64 (2002) Keywords: Amino Acid Sequence Animals Antibodies, ...
Fluorene degradation by Sphingomonas sp. LB126 proceeds through protocatechuic acid: a genetic analysis.
energy. In the present study, a mutagenic vector was constructed and a “plasmid rescue” strategy was set up to isolate a 16.5-kb DNA fragment containing genes required for fluorene degradation. A 14.5-kb ...
Effect of TNF-alpha on LH and IGF-I modulated chicken granulosa cell proliferation and progesterone production during follicular development.
proliferation. The observation that the HD11-conditioned medium contained TNF-alpha indicates that TNF-alpha produced by macrophages found in chicken follicles modulates granulosa cell growth and differentiation. ...
Isolation of adherent polycyclic aromatic hydrocarbon (PAH)-degrading bacteria using PAH-sorbing carriers.
liquid mineral medium in which PAH s were supplied as crystals and (ii) a new method in which PAH degraders were enriched on and recovered from hydrophobic membranes containing sorbed PAH s. Both ...
