Hemorrhagic bowel syndrome in dairy cattle: Gross, histological, and microbiological characterization.
originate from small mucosal erosions through dissecting hemorrhage within the lamina muscularis mucosae. No invasive fungal growth was observed in any tissue. Bacteriological cultivation and nanopore ...
Reliability of Morphological and PCR Methods for the Official Diagnosis of Aethina tumida (Coleoptera: Nitidulidae): A European Inter-Laboratory Comparison.
The Small Hive Beetle (Murray, 1867) is an invasive scavenger of honeybees. Originally endemic in sub-Saharan Africa, it is regulated internationally in order to preserve the areas still free from this ...
A non-invasive fluorescent staining procedure allows Confocal Laser Scanning Microscopy based imaging of Mycobacterium in multispecies biofilms colonizing and degrading polycyclic aromatic hydrocarbons.
with bacteria belonging to other genera by means of Confocal Laser Scanning Microscopy (CLSM), a procedure was developed to non-invasively and fluorescently stain Mycobacterium without compromising the ...
Influence of temperature, oxygen and bacterial strain identity on the association of Campylobacter jejuni with Acanthamoeba castellanii.
sources of poultry. In this study, the ability of five Campylobacter jejuni strains with different invasion potential towards Caco-2 cells to survive and replicate in the protozoan Acanthamoeba castellanii ...
Alien invasive birds.
Animals Behavior, Animal Birds Ducks Geese Humans Introduced Species Passeriformes Psittacula Starlings Abstract: A bird species is regarded as alien invasive if it has been introduced, intentionally or ...
Host- and tissue-specific pathogenic traits of Staphylococcus aureus.
detected among invasive human strains. The virulence potential, as indicated by the number of virulence genes per strain, did not differ significantly between the human- and animal-related strains. Our data ...
Putative roles of the CNF2 and CDTIII toxins in experimental infections with necrotoxigenic Escherichia coli type 2 (NTEC2) strains in calves.
colostrum-restricted calves were orally inoculated with an Escherichia coli strain, identified originally as non-pathogenic, and into which the plasmid pVir was conjugally transferred. This resulted in diarrhea, ...
PCNA and Ki67 proliferation markers as criteria for prediction of clinical behaviour of melanocytic tumours in cats and dogs.
predominant histological cell type, invasive growth and clinical outcome were recorded for each case. In addition, the proliferation (phase) index and growth fraction were measured, after bleaching, by means of ...
Differential secretion of interleukin-8 by human epithelial cell lines upon entry of virulent or nonvirulent Yersinia enterocolitica.
among the first cells encountered by invasive pathogens. Bacterial invasion of the mucosa gives rise to an inflammatory response, characterized by the influx of polymorphonuclear leukocytes. The ...
Pathogenic properties of Escherichia coli strains isolated from diarrheic commercial rabbits.
bacilli were studied. None of the strains produced thermostable or thermolabile enterotoxins, and none was invasive. Strains isolated from suckling rabbits attached in vitro to the brush borders of ...
