Human infestation by Ophionyssus natricis snake mite

Area of Science:

• Dermatology
• Zoology
• Parasitology

Background:

• The snake mite, Ophionyssus natricis, is an ectoparasite that primarily infests reptiles.
• Human infestation by snake mites is rare but can occur through close contact with infected pets.

Observation:

• A family presented with a papular and vesiculo-bullous skin eruption.
• The eruption was clinically suspected to be caused by an arthropod bite.
• A pet python in the household was identified as the likely source of the infestation.

Findings:

• Microscopic examination and identification confirmed the causative agent as the snake mite, Ophionyssus natricis.
• The family members' skin lesions resolved completely after the pet python and its enclosure were treated.
• This case highlights the potential for zoonotic transmission of snake mites to humans.

Implications:

• Proper veterinary care and environmental hygiene are crucial for pet owners, especially those with reptiles.
• Physicians should consider rare zoonotic causes like snake mites in the differential diagnosis of unexplained skin eruptions.
• Public health awareness regarding reptile-associated zoonoses can prevent similar occurrences.
