Summary
Red complex bacteria, including Tannerella forsythia and Porphyromonas gingivalis, are linked to canine periodontal disease. Their presence, particularly together, correlates with gingivitis and periodontitis in dogs.
Area of Science:
- Veterinary Microbiology
- Periodontology
- Canine Health
Background:
- Red complex bacteria (Treponema denticola, Tannerella forsythia, Porphyromonas gingivalis) are implicated in human periodontal disease.
- Understanding the role of these bacteria in canine periodontal disease is crucial for animal health.
Purpose of the Study:
- To investigate the association between red complex bacteria and periodontal disease in dogs.
- To compare the prevalence of these bacteria in diseased versus healthy canine subjects.
Main Methods:
- Subgingival plaque samples were collected from 73 dogs of varying ages.
- Polymerase chain reaction (PCR) assay was used to detect Treponema denticola, Tannerella forsythia, and Porphyromonas gingivalis.
Main Results:
- Tannerella forsythia and Porphyromonas gingivalis were detected in 49.3% of the dogs.
- Dogs with gingivitis or periodontitis showed a significantly higher likelihood of infection with T. forsythia and P. gingivalis (OR 5.4).
- Only 4.1% of samples were positive for all three red complex bacteria, with no significant association to periodontal disease.
Conclusions:
- The findings suggest a similar role for red complex bacteria in canine periodontal disease as observed in humans.
- The concurrent presence of Tannerella forsythia and Porphyromonas gingivalis is correlated with periodontal disease in dogs.
- Further research may explore the specific synergistic effects of these bacteria in canine periodontitis.

01:27The Oral Microbiota
90
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

1.5K
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...

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...

Proteobacteria, one of the largest and most diverse bacterial phyla, encompasses a wide range of Gram-negative bacteria distinguished by their outer membrane composed of lipopolysaccharides. These microorganisms exhibit various metabolic capabilities, including phototrophy, chemolithotrophy, and heterotrophy, and thrive in diverse environments from soil to aquatic systems and host-associated niches. The phylum is divided into six classes: Alphaproteobacteria, Betaproteobacteria,...

01:25Clinical Significance of Antibiotic Resistance
90
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within...

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
