Serological characteristics within the genus Desulfovibrio
Antonie Van Leeuwenhoek
|January 1, 1980
Summary
Antisera revealed highly specific surface antigens in Desulfovibrio bacteria using agglutination tests. Immunodiffusion identified a genus-specific antigen, with some species-specific antigens also detected.
Area of Science:
- Microbiology
- Immunology
- Bacteriology
Background:
- Desulfovibrio bacteria are anaerobic sulfate-reducing microorganisms.
- Understanding the antigenic diversity of Desulfovibrio is crucial for accurate identification and epidemiological studies.
Purpose of the Study:
- To investigate the specificity of surface antigens in Desulfovibrio species.
- To determine the potential for using these antigens in serological identification methods.
Main Methods:
- Preparation of antisera against Desulfovibrio desulfuricans, D. vulgaris, and D. salexigens.
- Testing antisera cross-reactivity against 36 heterologous Desulfovibrio strains.
- Utilizing agglutination titration and double immunodiffusion techniques.
Main Results:
- Agglutination tests showed minimal cross-reactivity, even within the same species, indicating high antigen specificity.
- Double immunodiffusion revealed a genus-specific antigen present in most strains.
- A species-specific antigen was identified for D. salexigens, with other common antigens showing random distribution.
Conclusions:
- Desulfovibrio surface antigens are generally highly specific, limiting broad serological classification.
- A genus-specific antigen exists, but its utility may be limited by the presence of other randomly distributed antigens.
- Further research may refine serological methods for specific Desulfovibrio species identification.

01:26Bacterial Phylum Bacteroidota
The phylum Bacteroidota includes over 700 species classified into four primary orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These gram-negative, non-sporulating rods exhibit saccharolytic capabilities and can be aerobic or fermentative, encompassing obligate aerobes, facultative aerobes, and obligate anaerobes. Many species display gliding motility, though some are nonmotile or use flagella. The genus Bacteroides is well-studied due to its significant role in...
01:24Bacterial Phylum Tenericutes
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...
01:18Other Unique Bacteria
Magnetic bacteria exhibit a directed movement called magnetotaxis, driven by structures called magnetosomes. These magnetosomes consist of chains of magnetic particles made of either magnetite (Fe₃O₄) or greigite (Fe₃S₄) and are organized in a linear conformation by a protein scaffold within invaginations of the cell membrane. The bacteria align along the north–south magnetic field lines, much like a compass needle. They are typically microaerophilic or anaerobic and are commonly found near the...
01:29Viruses of Archaea
Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...
01:26Bacterial Phylum Verrucomicrobiota
The phylum Verrucomicrobiota comprises at least four characterized orders, with most species classified within the order Verrucomicrobiotales. Members of this phylum are either aerobic or facultatively aerobic, with the ability to ferment sugars. A notable exception is the genus Methylacidiphilum, which consists of aerobic methanotrophs. Additionally, some Verrucomicrobiota establish symbiotic relationships with protists. These bacteria are widely distributed across various environments,...
01:18Deep Sea Microbial Ecology
The deep ocean and its underlying sediments represent vast, largely unexplored microbial habitats that extend far beyond the sunlit photic zone. The photic (euphotic) zone typically spans the upper ~100–200 meters of pelagic waters in the open ocean, but its depth varies geographically and seasonally, where sufficient light supports photosynthetic life. Below this lies the deep sea, spanning roughly 1000–6000 meters (bathypelagic to abyssal zones), with deeper hadal trenches extending beyond...
