REVIEW OF OUR KNOWLEDGE OF BACTERIUM TULARENSE.
Summary
Bacterium tularense causes animal diseases with plague-like lesions and deer-fly fever in humans. This organism is distinct from the plague bacillus and requires egg-yolk medium for growth.
Area of Science:
- Microbiology
- Veterinary Pathology
- Infectious Diseases
Background:
- Bacterium tularense causes animal diseases with lesions similar to plague.
- In humans, Bacterium tularense infection results in deer-fly fever.
- The bacterium's morphology is distinct from the plague bacillus.
Purpose of the Study:
- To differentiate Bacterium tularense from the plague bacillus.
- To highlight the etiological agent of deer-fly fever.
- To describe the unique growth requirements of Bacterium tularense.
Main Methods:
- Comparative pathological analysis of animal lesions.
- Clinical observation of human cases.
- Bacteriological culture on specialized media.
Main Results:
- Lesions caused by Bacterium tularense are indistinguishable from plague in animals.
- Bacterium tularense is identified as the cause of deer-fly fever in humans.
- The organism exclusively grows on egg-yolk medium.
Conclusions:
- Bacterium tularense is an important zoonotic pathogen with distinct clinical and microbiological characteristics.
- Accurate identification is crucial for differentiating it from plague.
- Specific culture methods are necessary for its isolation and study.

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...
01:30Bacterial Phylum Spirochaetes
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...
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...
01:26Bacterial 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,...
01:28Methods of Classification and Identification
Bacterial identification relies on a diverse array of techniques to classify and understand microorganisms, each tailored to uncover specific characteristics. Traditional morphological approaches, while still valuable, are limited for closely related or structurally simple organisms. Modern methods integrate biochemical, serological, genetic, and advanced molecular tools to achieve greater accuracy.Morphological and Biochemical TechniquesMorphological characteristics, such as cell shape and...
01:26Bacterial Phylum Planctomycetes
Planctomycetes are a group of morphologically distinct bacteria predominantly classified into two orders: Planctomycetales and Brocadiales. These gram-negative bacteria exhibit unique features, including division by budding and the presence of stalks or appendages. Their cells are often found in rosette arrangements, and they are notable for possessing an S-layer in their cell envelope, which is relatively uncommon among bacteria. Additionally, Planctomycetes frequently exhibit intracellular...
