[Pyocyaneus infection of burn wounds]
Abstract:
Materials of clinico-bacteriological study of 302 patients with thermal burns of different severity pointed to a considerable elevation of the incidence of Ps. aeruginosa isolation (in cultures) from burn wounds; the last few years it was found in about 50% of the cases. The greater frequency of Ps. aeruginosa detection correlated with the increase of the severity of the affection. By using Soviet set of 17 type agglutinating sera it was possible to type almost 90% of the Ps. aeruginosa cultures isolated from the wounds; a marked prevalence (over 70% of the strains) of cultures belonging to the serological group II was revealed. Patients admitted to the burn centre at early periods after the trauma displayed infection of the wound with the Ps. aeruginosa strain of the II serological group.
Insights
Pseudomonas aeruginosa (Ps. aeruginosa) infections are common in burn wound patients, particularly with severe burns. Serological group II strains were most prevalent and often caused early infections in burn patients.
Area of Science:
- Clinical Microbiology
- Burn Wound Infections
- Bacteriology
Background:
- Burn wound infections represent a significant clinical challenge.
- Pseudomonas aeruginosa (Ps. aeruginosa) is a common opportunistic pathogen in burn patients.
- The incidence of Ps. aeruginosa in burn wounds has been noted to be considerable.
Purpose of the Study:
- To investigate the incidence and serological typing of Ps. aeruginosa in patients with thermal burns.
- To determine the correlation between burn severity and Ps. aeruginosa infection rates.
- To identify specific serological groups of Ps. aeruginosa prevalent in burn wound infections.
Main Methods:
- Clinico-bacteriological study of 302 patients with thermal burns.
- Isolation and culture of Ps. aeruginosa from burn wounds.
- Serological typing of Ps. aeruginosa using a set of 17 Soviet type agglutinating sera.
Main Results:
- Ps. aeruginosa was isolated from approximately 50% of burn wound cultures.
- A higher frequency of Ps. aeruginosa detection correlated with increased burn severity.
- Over 70% of isolated strains belonged to serological group II.
- Early-admitted patients frequently showed infection with serological group II Ps. aeruginosa.
Conclusions:
- Ps. aeruginosa is a frequent causative agent of burn wound infections, with incidence increasing with burn severity.
- Serological group II is the predominant type of Ps. aeruginosa found in burn wounds.
- Early burn wound infections are often associated with serological group II Ps. aeruginosa strains, highlighting the need for targeted interventions.
