Anaerobic Gram Negative Nonsporing Bacteria from the Caeca of Poultry

Journal of Applied Bacteriology, 1968
SUMMARY Four groups (1, 4, 5 and 6) of Gram negative, nonsporing anaerobic rods (family Bacteroidaceae) which have been isolated from the caeca of chickens, turkeys and ducks, are described. Two of the groups (1 and 6) belong to the genus Sphaerophorus but differ in a number

Endotoxins of gram-negative anaerobic bacteria

Infection, 1980
The author reviews the data available on endotoxins of Fusobacterium, Sphaerophorus, Leptotrichia, and Veillonella species, and reports his own findings with lipopolysaccharides extracted from Bacteroides fragilis strains by the trichloroacetic acid method. The latter extracts showed a very low toxicity for mice after i.v.

Cytoplasmic glycogen inclusions in cells of anaerobic gram-negative rumen bacteria

Canadian Journal of Microbiology, 1973
Megasphaera elsdenii, an anaerobic rumen bacterium, produced intracellular polysaccharide granules varying in size from 0.05 to 0.15 μm during growth in batch culture. This polysaccharide material was purified and was found to contain D-glucose as the only reducing sugar.

Bactericidal Antibody in Mammalian Serum to Obligatorily Anaerobic Gram-Negative Bacteria

The Journal of Immunology, 1966
Summary A modification has been made of the quantitative photometric serum bactericidal procedure for use with obligatorily anaerobic Gram-negative bacteria. This required the incubation of the serum-sensitive anaerobic bacteria with antibody and complement in an atmosphere containing 95% N-5% CO2.

Role of Structural and Extracellular Virulence Factors in Gram-Negative Anaerobic Bacteria

Clinical Infectious Diseases, 1994
Gram-negative anaerobic bacteria belonging to the genera Bacteroides, Prevotella, and Porphyromonas represent the most common cause of endogenous, usually mixed, infections occurring after abdominal or gynecologic surgery. Anaerobes are important pathogens in oral-cavity infections as well as in systemic infections that originate from the mouth ...

Immune responses to anaerobic gram‐negative bacteria in health and disease

Food / Nahrung, 1984
AbstractIn the serum of healthy and sick persons antibodies to Bacteroidaceae and Veillonella have been detected. The antibody titres to these anaerobic bacteria are commonly low, in adults, however, higher than in children. High antibody titres could be found in patients suffering from Crohn's disease and in cancer patients.

Antibacterial effects of endodontic irrigants on black-pigmented Gram-negative anaerobes and facultative bacteria

Journal of Endodontics, 1998
The antibacterial effect of endodontic irrigants was evaluated against four black-pigmented Gram-negative anaerobes and four facultative anaerobic bacteria by means of the agar diffusion test. All solutions used were inhibitory against all bacterial strains tested.

Gram-negative anaerobic bacteria

2013
Najznačajniji gram-negativni anaerobi koji koloniziraju gornji dišni, probavni i spolno- mokraćni sustav ljudi pripadaju rodovima: Bacteroides, Fusobacterium, Porphyromonas, Prevotella i Veillonella. Svi su štapići, osim Veillonella koji ima oblik koka. Sve su ove bakterije asporogene.

Adhesion of anaerobic gram-negative bacteria to mucosal surfaces.

Scandinavian journal of infectious diseases. Supplementum, 1986
Fusobacterium nucleatum and black-pigmented Bacteroides species adhere to red blood cells and crevicular epithelium. The attachment of the bacteroides, but not F. nucleatum, is associated with the presence of fimbriae-like structures on the bacterial surface.
