A critical reflection on current control of Toxocara canis in household dogs

  title={A critical reflection on current control of Toxocara canis in household dogs},
  author={E R Nijsse},
Toxocara canis is a roundworm that is common worldwide and also in Dutch household dogs. Adult stages of T. canis can be present in the small intestines of dogs where they produce large numbers of eggs that are shed in the environment (patent infection). Because very young dogs and humans can develop symptoms after infection with infective eggs, the current advice is to deworm all dogs four times a year. However, the vast majority of dogs older than six months will not develop a patent…

The ascarids T. canis and T. cati continue to be a significant zoonotic disease in North America and underscores the need for the veterinary profession to control ascarid infections in cats and dogs at every opportunity.

Preventive measures consist of preventing contamination of the environment with Toxocara eggs and for education of pet owners and non-pet owners to increase awareness about potential zoonotic hazards.
Patent Toxocara canis infections in previously exposed and in helminth-free dogs after infection with low numbers of embryonated eggs.
The controlled induction of patent infections with low doses of embryonated eggs was investigated in 18 beagles in a 7-month study until their 16th life month, finding that dogs of all ages are at risk to develop patent T. canis infections.
Observations on the development of Toxocara canis (Werner, 1782) in the dog.
Differences in migratory behaviour are adaptations to prevailing modes of nutrition and it is suggested that the somatic migration occurring in dogs is an adaptation to the non-predatory habits of this particular host.

The visceral infection of humans with Toxocara canis is particularly prevalent in children and may cause a variety of symptoms that commonly persist for 6-24 months. The ocular infection usually
Repeated patent infection of adult dogs with Toxocara canis.
The findings imply that adult dogs may not always be immune to toxocaral infection and may therefore contribute significantly to the problem of environmental contamination with T. canis ova.
Incidence of patent Toxocara canis infection in bitches during the oestrous cycle.
It is concluded that cyclic beagle bitches, in which prolactin levels increase in the second half of the luteal phase, are unlikely to be at higher risk for patent T. canis infection than in other phases.
Control of Echinococcus multilocularis: strategies, feasibility and cost-benefit analyses.
Considering the high reproduction of E. multilocularis in domestic dogs which live in close contact to humans, a monthly deworming scheme for domestic dogs with access to rodents is likely to be of high importance and long-term baiting campaigns are actually the most effective tool to significantly lower the infection pressure with parasite eggs.
Toxocara canis in household dogs: prevalence, risk factors and owners’ attitude towards deworming
It was concluded that the prevalence of Toxocara egg-shedding household dogs is almost unchanged over recent years and that the knowledge of owners is insufficient to expect sound decisions on routine deworming.
