Estefanofilariose em humanos: ocorrência e mecanismos de transmissão / Stephanofilariasis in humans: occurrence and transmission mechanisms

Descreve-se aqui o encontro do helminto Stephanofilaria spp., em dermatite nodular ulcerativa em seres humanos, sendo as ulceras pesquisadas de dimensões variadas e com alguns anos de existência. Acredita-se que, a presença desse parasita, que afeta diversas espécies de animais domésticos e silvestres, possa agravar o quadro com as lesões produzidas nos vasos venosos e linfáticos, reduzindo a circulação, retardando a cicatrização. O ciclo deste parasita no ser humano, também é descrito.

This work describes the occurrence of the helminth Stephanofilaria spp in ulcerative nodular dermatitis in humans. The ulcers observed presented a variety of sizes and some years of existence. It is believed that the presence of this parasite, which affects several domestic and wild animal species, may harm human health through lesions produced in venous and lymphatic vessels that reduce blood circulation and retard the healing process. The cycle of this parasite in humans is also described.

Studies on animal schistosomes in Peninsular Malaysia: record of naturally infected animals and additional hosts of Schistosoma spindale.

Surveillance studies on cercarial dermatitis were carried out in paddy growing areas in Peninsular Malaysia. It was observed that dermatitis in paddy planters occurred in paddy fields which were cultivated using animals such as bafflos or fields where domestic animals were allowed to graze during the off planting season as these animals harbored the parasite. The causative agent of cercarial dermatitis was Schistosoma spindale. A total of 215 small mammals trapped from Alor Setar and 126 trapped from Labu were examined for the schistosome. In Alor Setar Bandicota indica, Rattus argentiventer and Rattus rattus diardii were the only wild mammals found to be infected with the parasite, while in the Labu areas only Rattus tiomanicus jalorensis was positive for the schistosome. The occurrence of S. spindale in R. argentiventer and R.r. diardii in Alor Setar and in R.t. jalorensis in Labu constitute new host and geographic distribution records of the schistosome.
