Seabather's eruption: report of five cases in southeast region of Brazil

The authors report five cases of seabather's eruption, a typical dermatitis associated predominantly to the jellyfish Linuche unguiculata (Cnidaria), that causes erythematous and pruriginous papules on areas of the skin of bathers covered by swimsuits. The rash is characteristic and the eruption is commom in the Caribbean, Florida, Mexico and Gulf States of USA. The cases are the first reported in Brazil and larvae of the jellyfish are present in the waters where the accidents happened.

dogs may be a reservoir host for Angiostrongylus costaricensis

Angiostrongylus costaricensis is a parasitic nematode of wild rodents. Several other vertebrate species including man may become infected by ingestion of the third stage larvae produced by the intermediate hosts, usually slugs from the family Veronicellidae. There is a report of the diagnosis of abdominal angiostrongyliasis in Canis familiaris with lesions resembling those found in human disease. As a preliminar evaluation of the adequacy of a canine model for pathogenetic studies, a dog was inoculated with 75 L3 of A. costaricensis. Infection was established and fist stage larvae were found in feces up to 88 days post infection, sometimes in very large numbers (9.5 x 10(4) L1/g). No clinical manifestations or significant lesions were detected. These are indications that dog may play a role as a reservoir host for A. costaricensis.
