Summary
Chromobacterium violaceum causes rare, fatal infections in animals and humans. Early identification and fluoroquinolone treatment are crucial for survival in systemic cases.
Area of Science:
- Veterinary Medicine
- Infectious Diseases
- Microbiology
Background:
- Chromobacterium violaceum is a soil and water saprophyte found in tropical and subtropical regions.
- This bacterium is known to cause rare but severe and often fatal infections in both animals and humans.
Observation:
- Two critically ill dogs in Florida were diagnosed with systemic Chromobacterium violaceum infection.
- Neither dog presented with a fever, a common sign of infection.
Findings:
- Despite surgical intervention and intensive care, only one of the two dogs survived the infection.
- The presence of violet-pigmented colonies on microbial cultures is a key diagnostic indicator.
Implications:
- Prompt recognition of C. violaceum is vital for microbiologists and clinicians managing potentially fatal infections.
- Empirical treatment with fluoroquinolones is recommended due to the infection's rapid progression, pending susceptibility results.

01:29Bacterial Phylum Chlamydiae
The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic of...
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...
01:25Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
