The aim of this study was to establish reference concentrations (LC 50 e LC 90 ) of aqueous extracts of Bidens pilosa on the land snail Subulina octona, in order to assess the changes caused by 24 and 48 h exposure to the sublethal concentration regarding species' fecundity, hatchability and in offspring produced after exposure to confirm the presence of tannins, saponins and flavonoids in this plant species. Eggs newly hatched and 30 day-old snails were exposed to sublethal concentration, calculated for adults. The phytochemical analysis confirmed the presence of flavonoids, condensed tannins and saponins in the aqueous extract of B. pilosa. The LC 50 and LC 90 obtained were 51.4mg/mL and 74.1mg/mL respectively. The exposure to sublethal concentration reduced significantly the hatchability and the survival of the offspring hatched from exposed eggs and also caused a reduction on survival and growth in snails exposed for both time period. The exposure time also caused a reduction at the evaluated parameters.

“…To acquire an infection, the bird must ingest the infective form of the parasite, the metacercariae encysted in the tissues of infected mollusks. The mollusks reported as the intermediate hosts for Paratanaisia in Brazil are the land snails Leptinaria unilamellata (KELLER & ARAÚJO, 1992) and Subulina octona (BRANDOLINI & AMATO, 2006), which are very small, 4-5 mm and 13 mm, respectively (ARAÚJO & BESSA, 1993;ARAÚJO & KELLER, 1993). These species are commonly observed in shaded and humid places such as under rock and plant surfaces and in construction cracks (ARAÚJO & BESSA, 1993).…”

Digenetic eucotylids of the Paratanaisia genus are widely reported parasites of the avian renal system. The infection, commonly reported in free-living and zoo-housed birds, is described for the first time in a domiciled bird, a cockatiel kept as pet bird with free access to the yard outdoors. The bird was received at Veterinary Hospital, where clinical and radiographic evaluations suggested a case of heavy-metal poisoning. Although the bird received supportive care and a chelating agent, it died the next day. The necropsy showed friable kidneys and congestion of blood vessels in structures such as the skin, proventriculus, brain, and skullcap. The histopathological evaluation of the kidneys revealed multifocal hemorrhages, commonly found in cases of heavy-metal poisoning. Parasitic structures similar to those of the digenean trematodes Paratanaisia spp. were also observed inside dilated collecting ducts, which presented epithelial cell flattening and vacuolization. There was compression of adjacent tissue and discrete fibrotic areas. In the presence of intermediate hosts in the yard, the synanthropic nature of some wild free-living birds could make them a source of trematodes infection and dissemination for pet birds. Conversely, the infected cockatiel could also have served as a reservoir and carrier of trematodes to wild free-living birds.
