In order to study the environmental contamination by Toxocara spp. eggs in a rural community from the Pontal do Paranapanema region, São Paulo State, Brazil, soil samples from 31 out of 121 plots were collected in eight different places on each house. The samples were submitted to flotation technique in sodium nitrate (d = 1.20 g/cm3). Eggs of Toxocara spp. were recovered in nine (29.03%) out o...

Human toxocarosis is an important parasitic zoonosis caused by larval stages of Toxocara species, the roundworms from dogs and cats. Larval migration through different soft tissues in the human generates several clinical entities in the patient, such as visceral larva migrans, ocular toxocarosis, and neurotoxocarosis. Definitive diagnosis by histopathological methods is very difficult or almost...

A four-year-old boy was seen in the Eye Department at the Queen Elizabeth Military Hospital, Woolwich, because his parents had noticed that his right pupil appeared white. The diagnosis of toxocaral endophthalmitis was later made. The pathogenesis and management of infestation by Toxocara species are described.

BACKGROUND Human toxocariasis is primarily a soil-transmitted zoonosis, so children with geophagia are at an increased risk of toxocariasis, especially those living in homes with puppies that have not been dewormed. CASE REPORT A 17-months-old female presented to our department with fever, abdominal distention and marked eosinophilia. Iron deficiency anemia, marked leukocytosis (79,000 cells/...

AIMS To evaluate an antigen capture enzyme linked immunosorbent assay (ELISA) which detects a carbohydrate epitope on the excretory-secretory (ES) antigens of Toxocara canis in clinical practice. METHODS Serum specimens from healthy adults, patients with acute visceral larva migrans, ocular and inactive toxocariasis, and with other helminth infections were examined by two site antigen capture...

Cutaneous larva migrans (CML) is a frequent parasitic infestation caused by migration of animal hookworm larvae into the human epidermis. This skin disease is common in warmer climates among people, who have contact with contaminated soil. Clinical manifestation of CML is an itchy, erythematous, linear tract, which appears days to even months after exposure to infested sand or soil. Diagnosis i...

Hookworm-related Cutaneous Larva Migrans (HrCLM) is a pruritic serpiginous cutaneous eruption caused by animal hookworms commonly found in tropical and subtropical areas, especially the Southeastern United States. We describe here a very exceptional HrCLM case showing multiple larva entries/lesions in a 63-yearold white male living in Miami. Clinically he presented with multiple pruritic erythe...

Case report A 58 year old non-smoking caucasian woman noticed an itchy rash on her buttocks on 29 October 1983, two days before returning to London from her holiday in Barbados. Her travelling companions were unaffected. On her return similar lesions developed on her legs and abdomen. On 15 November she noticed a cough, which was dry until 25 November, when she produced a little white sputum. T...

A case of massive Ancylostoma sp. larval infestation is presented in a patient who had received systemic corticosteroid therapy. What attracts attention in this case is the exuberance and rarity of clinical manifestation. Based on the pertinent literature, we discuss the mechanisms of parasital infection, the natural history of the disease and its treatment.
