Abstract
Cystic Echinococcosis (CE) is a neglected
tropical disease (NTD) impacting the health and economy of the developing states
including Pakistan. It is mainly caused by Echinococcus granulosus and
renders huge economic losses to the livestock sector. This study investigated
the prevalence of CE and associated risk factors. A total of 503 samples from
food animals (including 226 cows, 102 buffaloes, 98 sheep, and 77 goats) were
inspected for the presence of hydatid cysts by conducting postmortem at various
slaughterhouses in district Narowal-Pakistan. Fertility and viability of
collected hydatid cysts were assessed by microscopy and confirmatory diagnosis
was obtained through conventional Polymerase Chain Reaction (PCR). A
pre-structured questionnaire was used to collect baseline data in order to
identify the associated risk factors with CE. An overall prevalence of 8.15% was
found while in each species it was 12.83% in cattle, followed by buffalo
(6.86%), sheep (4.08%) and goat (1.29%), respectively. The order of infection
was highest in liver (35.71%) followed by lungs (33.33%) and then both organs at
the same time (20%). Such epidemiological findings could help in developing
preventive strategies and control programs for CE in Pakistan and other
developing countries.
