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.
genotype of bovine viral diarrhoea virus (BVDV), designated BVDV-2, has emerged in the last decade and in recent years the prevalence of BVDV-2 strains has increased. A vaccination-challenge study was ...
Dual labeling of Pseudomonas putida with fluorescent proteins for in situ monitoring of conjugal transfer of the TOL plasmid.
knowledge, this is the first study that discusses the coexpression of GFP and DsRed for conjugal gene transfer studies. Health Topics: Animal health Category: A1 FOS Classification: 4.03 Veterinary science ...
Risk analysis of the spread of classical swine fever virus through "neighbourhood infections" for different regions in Belgium.
a second part of the study, the likelihood for the occurrence of neighbourhood infections within an area with a 1 km radius was predicted for every Belgian pig herd, assuming that the herd was infected with ...
Elucidation of the metabolic pathway of fluorene and cometabolic pathways of phenanthrene, fluoranthene, anthracene and dibenzothiophene by Sphingomonas sp. LB126.
fluoranthene, anthracene and dibenzothiophene in Sphingomonas sp. LB126 were examined. To our knowledge this is the first study on the cometabolic degradation of the three-ring PAH s phenanthrene, anthracene and ...
Use of the pAL5000 replicon in PAH-degrading mycobacteria: application for strain labelling and promoter probing.
PAH-derived fluorescence as assessed by confocal laser scanning microscopy. The results reported here demonstrate the suitability of the pAL5000 replicon for the development of recombinant DNA-based studies in ...
Patterns of Mycoplasma hyopneumoniae infections in Belgian farrow-to-finish pig herds with diverging disease-course.
Issue 7, p.349-53 (2002) Keywords: Animal Husbandry Animals Belgium DNA, Bacterial Mycoplasma Pneumonia of Swine, Mycoplasmal polymerase chain reaction Seroepidemiologic Studies Swine Swine Diseases ...
The effect of vaccination with a Salmonella enteritidis aroA mutant on early cellular responses in caecal lamina propria of newly-hatched chickens.
strain, they induce a rapid onset of resistance to intestinal colonization by other Salmonella strains. The exact mechanism of this early colonization-inhibition is not known. To study host-related ...
The diversity of microorganisms associated with Acromyrmex leafcutter ants.
almost any environment that has so far been investigated. This study presents a systematic survey of the microbial diversity associated with a population of Acromyrmex leafcutter ants. In contrast to ...
Dynamics of immune cell infiltration in the caecal lamina propria of chickens after neonatal infection with a Salmonella enteritidis strain.
Infections, Animal Spleen T-Lymphocytes Abstract: Dynamics of leucocyte infiltration and bacterial invasion in the caecal wall were studied after oral infection of 2-day-old chicks with Salmonella enterica ser. ...
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 ...
