AI Article Synopsis
- A survey conducted in Japan from 1997 to 2007 found that 0.4% of pet dogs in Hokkaido, the only endemic region for Echinococcus multilocularis, tested positive for the parasite's DNA.
- Most infected dogs were free-range, but a few were kept indoors, highlighting the risk of indoor dogs being carriers.
- The study emphasizes the need for proper pet management to prevent the spread of infections, especially since infected dogs can transport the parasite to non-endemic areas like Honshu.
Article Abstract
A survey of Echinococcus multilocularis infections in pet dogs in Japan from 1997 to 2007 was conducted by testing for coproantigen reactivity, fecal taeniid eggs, and egg DNA. In Hokkaido, the only island where E. multilocularis is endemic in Japan, 18 of 4768 dogs (0.4%) excreted taeniid eggs that were positive for E. multilocularis DNA by polymerase chain reaction (PCR). Most of the dogs testing positive for egg DNA were kept free-range, but three dogs had been kept inside their owners' houses. In addition, 15 dogs were suspected to be infected based on the results of a coproantigen test. One dog, which was transported from Hokkaido to Honshu, the main island of Japan, was excreting taeniid eggs that were positive for E. multilocularis DNA by PCR. These results suggest the importance of proper pet management in disease prevention, even for dogs kept indoors, and they point out a possible means by which the parasite may be introduced into non-endemic areas through transport of infected dogs.

Cystic and alveolar echinococcosis are severe zoonotic diseases characterized by long asymptomatic periods lasting months or years. Viable Echinococcus spp. eggs released into the environment through the feces of canids can infect humans through accidental ingestion via hand-to-mouth contact or consumption of contaminated food or water.

Article Synopsis
- Cystic and alveolar echinococcosis are among the most significant foodborne parasitic diseases globally, primarily transmitted through microscopic eggs found in the feces of definitive hosts like dogs.
- The eggs can survive for weeks to years in outdoor environments, are affected by factors like weather and animals, and their transmission routes through food, water, and soil are complex and not fully understood.
- Recent studies have shown contamination of various environmental matrices by taeniid eggs, emphasizing the need for better detection methods and viable assessments to evaluate the risks of human infection.
