Abstract:
Though Chromobacterium violaceum is a common inhabitant of soil and water in tropical and sub-tropical regions, human infections are rare but when they do occur result in high mortality. Since the first case from Malaysia in 1927, about 150 cases have been reported in world literature. Till date 6 cases have been reported from southern and eastern parts of India. We report here a case of C. violaceum septicaemia, probably the first case from north India. The patient, a 6 and a half year old boy was admitted with high fever. The patient had anaemia, neutrophilic leucocytosis and bilateral chest infiltrates. Routine and bacteriological investigations were carried out to establish the aetiological diagnosis. C. violaceum was isolated in pure culture from blood and pus. The patient was successfully treated with ciprofloxacin and amikacin. This is probably the first documented case report of C. violaceum infection from north India and the only Indian case with septicaemia which survived.
Insights
Chromobacterium violaceum infections are rare but deadly. This report details a rare case of C. violaceum septicemia in a child from North India, successfully treated with antibiotics.
Area of Science:
- Medical Microbiology
- Infectious Diseases
Background:
- Chromobacterium violaceum is a Gram-negative bacterium found in tropical and subtropical soil and water.
- Human infections are infrequent but associated with high mortality rates.
- Previous reports from India are limited to the southern and eastern regions.
Observation:
- A 6-year-old boy from North India presented with high fever, anemia, neutrophilic leukocytosis, and bilateral chest infiltrates.
- C. violaceum was isolated from blood and pus cultures.
- The patient exhibited symptoms consistent with severe sepsis.
Findings:
- This case represents the first documented instance of C. violaceum septicemia in North India.
- The patient demonstrated a successful clinical outcome following treatment with ciprofloxacin and amikacin.
- This is the only reported Indian case of C. violaceum septicemia with survival.
Implications:
- Highlights the potential for C. violaceum to cause severe infections in previously unreported geographical areas.
- Emphasizes the importance of considering C. violaceum in the differential diagnosis of sepsis, especially in febrile patients with relevant exposure history.
- Demonstrates the efficacy of fluoroquinolones and aminoglycosides in treating C. violaceum infections.
