Background: Larva migrans syndrome is a food-borne parasitic disease in humans, caused by accidental ingestion of eggs or larvae of ascarid nematodes, namely, Toxocara canis, Toxocara cati, or Ascaris suum, the roundworms commonly found in the intestines of dogs, cats and pigs respectively. When a patient is diagnosed as having larva migrans syndrome, oral-administration of albendazole is recommended, however, the regimen remains controversial worldwide. In Japan, the duration of albendazole administration is longer than those of European and North American countries. Read More

Ocular gnathostomiasis is rather a rare food-borne zoonosis caused by infection with the larvae of several species of genus Gnathostoma and is a representative ocular larva migrans syndrome. In our previous literature survey, we found 73 cases of ocular gnathostomiasis reported up to and including 2009, though additional sporadic cases have been reported in Asia and the Americas since that report. Here, we review 10 additional cases reported since 2010, and also update current findings regarding epidemiological and clinical features in affected patients. Read More

The increasingly urban nature of the population has led many people to choose independent pets, such as cats. This situation has also made it possible for these animals to be abandoned, thus increasing the numbers of cats on the streets and in shelters. These animals can act as a source of infection for other hosts. Read More

A total of 10 species of Baylisascaris, a genus of ascaridoid nematodes, occur worldwide and 6 of them occur in the New World. Most of the Baylisascaris species have a similar life cycle with carnivorous mammals or marsupials serving as definitive hosts and a smaller prey host serving as paratenic (or intermediate) hosts. However, one species in rodents is unique in that it only has one host. Read More

Climate changes may influence the frequency, intensity and geographical distribution of parasites, directly affecting their dispersive stages in the environment (eggs, larvae) and, indirectly, the larvae living mainly in invertebrate intermediate hosts. In biologically diverse nematodes climate warming contributes to the increase in the range of distribution, colonization of new hosts and modification of their development cycles. This is particularly acute in the Arctic and pertains, for instance, to nematodes Ostertagia gruehneri and Setaria tundra parasitizing reindeer Rangifer tarandus and Umingmakstrongylus pallikuukensis in musk oxen (Ovibos moschatus).

Toxocariasis is the clinical term used to describe human infection with either the dog ascarid Toxocara canis or the feline ascarid Toxocara cati. As with other helminths zoonoses, the infective larvae of these Toxocara species cannot mature into adults in the human host. Instead, the worms wander through organs and tissues, mainly the liver, lungs, myocardium, kidney and central nervous system, in a vain attempt to find that, which they need to mature into adults.
