Background: Cutaneous larva migrans (CLM) is caused by the penetration and migration of canine or feline hookworm larvae into the skin, and frequently affects travelers from high-income countries returning from tropical and sub-tropical areas. Unfortunately, this pathology is neglected due to poor understanding among both physicians and travelers. This study describes the profile of cases reported in Marseille, France. Read More

Human toxocariasis is caused by the nematode, Toxocara canis and it is a poorly understood phenomenon in Nigeria. Seroepidemiological studies have not been previously carried out among the preschool aged children in Nigeria.

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

Hookworm-related cutaneous larva migrans (HrCLM) is a zoonosis which is endemic in many sub-tropic and tropical countries including Malaysia. We report a case of a 40-year old plantation worker who presented with a pruritic rash on his abdomen. It is important for clinicians to diagnose and treat HrCLM promptly as this condition results in considerable morbidity when treatment is delayed. 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.
