Abstract This paper presents a method for equivalent emission source determination by application of LLAs (Large Loop Antennas). A review of different types of LLAs is carried out and their characteristics regarding emission source evaluation are emphasized. A hybrid technic is applied for obtaining the electric fields based on previous measurement of magnetic fields combined with an analytical and numerical approach. This methodology is proposed as an alternative to face the constraints concerning to the near electric fields measurements and calculations.

Resumo O presente estudo relata o primeiro registro da presença do nematódeo intestinal Strongyloides sp. em exames de fezes de um macho de Lutreolina crassicaudata, considerado um marsupial sinantrópico com potencial zoonótico. A técnica de Willis foi empregada no diagnóstico. Presença de ovos típicos de Strongyloides spp. foi detectada nas fezes. Uma coprocultura foi realizada para obtenção de estágios larvais, adultos de vida livre e larvas infectantes de terceiro estágio (L3) deste nematódeo após sete dias, os quais foram identificados morfologicamente como Strongyloididae. Este é o primeiro relato de infecção por Strongyloides sp. em uma cuíca de cauda grossa do Brasil.

Abstract The present study reports the first case of the presence of the intestinal nematode Strongyloides sp. in fecal examinations of a male Lutreolina crassicaudata, considered a synanthropic marsupial species with zoonotic potential. The Willis technique was used for the diagnosis. Presence of typical eggs of Strongyloides species in feces was detected. A fecal culture was performed to obtain larval stages, free-living adults and infective third stage larvae (L3) of this nematode after seven days, which was morphologically identified as Strongyloididae. This is the first report of infection by Strongyloides sp. in a tick-tailed opossum from Brazil.
