Abstract:
The authors describe a case of nosocomial myiasis of cavities caused by larvae of the fly Lucilia sericata (Meigen 1926), in a patient hospitalized at the resuscitation unit after a motor car accident where he suffered fractures of the skull and other injuries. On the fourth day in hospital in the nasal and oral cavity of the patient larvae of the 1st and 2nd instar of the mentioned species were detected. The ova were laid in hospital. L. sericata is the most frequent causal agent of tissue, cavity, ocular and urogenital human myiasis in Central Europe. In Czechoslovakia so far seven cases were recorded, incl. three nosocomial ones. Myiases usually attack immobile, injured or severely ill people in summer. It is important to draw attention to the hazard of myiases under exceptional conditions.
Insights
Nosocomial myiasis, caused by Lucilia sericata fly larvae, occurred in a hospitalized trauma patient. This highlights the risk of fly infestations in clinical settings, especially for vulnerable individuals.
Area of Science:
- Medical Entomology
- Clinical Medicine
- Infectious Diseases
Background:
- Nosocomial myiasis is a rare condition where fly larvae infest wounds or body cavities of patients in healthcare settings.
- Lucilia sericata (the common green bottle fly) is a frequent cause of myiasis in Central Europe, particularly affecting immobile or injured individuals.
Observation:
- A case of nosocomial myiasis is reported in a patient hospitalized after a severe motor vehicle accident with multiple injuries.
- Larvae of Lucilia sericata were detected in the patient's nasal and oral cavities on the fourth day of hospitalization.
- Evidence suggests the fly eggs were laid within the hospital environment, indicating a nosocomial transmission route.
Findings:
- The study confirms Lucilia sericata as a significant etiological agent of human myiasis, including cavity infestations.
- This case represents one of three recorded nosocomial myiasis instances in Czechoslovakia, emphasizing the potential for such infections in hospitals.
- Myiasis cases are typically observed in summer and predominantly affect individuals with compromised mobility or severe illness.
Implications:
- The findings underscore the importance of vigilant hygiene and environmental control in healthcare facilities to prevent fly infestations.
- Healthcare professionals should be aware of the risk of myiasis, particularly in trauma or intensive care units with vulnerable patient populations.
- This case highlights the need for heightened awareness regarding the hazard of myiases under exceptional circumstances and in hospital environments.
