Further Information
Occurrence in Bonobos
  • Necator americanus has been reported in Pan paniscus - Bonobo. (J576.13.w2)
  • A study of parasites in faeces of bonobos from Lomako, October-December 1998 found hookworm eggs (similar to Necator americanus) in 16.1% of samples. (B668.14.w14)
  • Ancyclostoma sp. infections are commonly found in orphaned bonobos in Kinshasa. (D386.4.3.w4c)
Diagnosis
  • In great apes, infection is diagnosed by identification of eggs in faeces; these should be cultured to produce larvae, allowing definitive identification. Identification of adult worms at necropsy. (B336.39.w39)
Treatment
Prevention

In great apes

  • Strict sanitation is important. (B336.39.w39)
  • Newly arrived animals should be quarantined and infected individuals should be isolated until they have been treated. (B336.39.w39)
