    Summary

    A 1974 study of hookworm infections in Surinam dogs and cats found decreased average hookworm loads. Ancylostoma braziliense distribution expanded, while Ancylostoma ceylanicum loads reduced.

    Area of Science:

    • Veterinary Parasitology
    • Helminthology
    • Tropical Medicine

    Background:

    • Hookworm infections pose a significant health concern for domestic animals.
    • Previous studies in Surinam in 1967 provided baseline data on hookworm distribution.

    Purpose of the Study:

    • To conduct a follow-up investigation on hookworm infections in dogs and cats.
    • To assess changes in hookworm distribution in Surinam since 1967.
    • To identify and quantify helminth species in domestic animals.

    Main Methods:

    • A survey was conducted between May and July 1974.
    • Fifty-two cats and 152 dogs were examined for helminths.
    • Helminths were isolated from various organs including the oesophagus, small intestine, coecum, and heart.

    Main Results:

    • A total of 15,942 helminths were isolated, with 14,006 being hookworms.
    • The primary hookworm species identified were Ancylostoma caninum, A. tubaeforme, A. ceylanicum, and A. braziliense.
    • The average hookworm load decreased since 1967, particularly for A. ceylanicum.
    • The distribution of A. braziliense significantly expanded eastward and southward in Surinam, but remained absent in the west.

    Conclusions:

    • Hookworm infection dynamics in Surinam's domestic animal population have changed since 1967.
    • Shifts in the prevalence and distribution of specific Ancylostoma species warrant continued monitoring.
    • Findings highlight the importance of ongoing epidemiological surveillance for parasitic zoonoses.
