Main hepatozoonosis affects canids and involves mainly Hepatozoon canis and Hepatozoon americanum. However, molecular studies revealed the capacity of H. canis to infect a wide range of wild mammals. In July 2018, we conducted an epidemiological survey for tick-borne pathogens in wild hosts, assaying Hepatozoon sp. occurrence of in 34 bats captured in different habitats within a conservation unit in the state of Espírito Santo, southeastern Brazil. Blood and spleen tissue DNA samples were submitted to PCR amplifications of Babesia/Theileria and Hepatozoon 18S rRNA gene and 21% (7/34) were positive for Hepatozoon sp. Phylogenetic inferences grouped the obtained sequences from Seba's short-tailed bat ( Carollia perspicillata) with the H. canis cluster, and from the great fruit-eating bat ( Artibeus lituratus) with rodent-associated Hepatozoon cluster....

Dracaena reflexa Lam is an arboreal species native to Madagascar and adjacent islands, which reaches four to six metters in height, and is used widely for urban landscaping and interior decoration. This attractive tropical monocotyledon grows at a moderate rate, and can be planted alone or in groups. Flowering begins towards the end of the austral winter, and continues until the end of the spring. The flowers are small and white, and are grouped in terminal inflorescences. The only known visitors/pollinators in Brazil are bees and wasps. Data were collected during the nocturnal monitoring of visitors to the flowers of D. reflexa plants on the Cascadura campus of the Souza Marques Technical Education Foundation in the city of Rio de Janeiro under moonlight and local illumination. For the identification of the bat species visiting the flowers, specimens ...

This mite species is commonly associated with ornamental plants and trees with bulbs, corms and tubers. The results of this study provided an insight into the phoretic relationship between mites and ants, indicating the role of the latter in the dispersion of the first. Despite the abundant and diverse mite fauna existing in ants, little is known about their diversity, biology, ecology and the nature of their associations.

(Proteaceae),Struthanthus syringifolius(Mart.) (Loranthaceae), andSchefflera vinosa(Cham. & Schltdl.) Frodin (Araliaceae) are plant species from the Brazilian Cerrado whose schistosomicidal potential has not yet been described. The crude extracts, fractions, the triterpenes betulin, oleanolic acid, ursolic acid and the flavonoids quercetin 3-O-β-D-rhamnoside, quercetin 3-O-β-D-glucoside, quercetin 3-O-β-D-glucopyranosyl-(1-2)-α-L-rhamnopyranoside and isorhamnetin 3-O-β-D-glucopyranosyl-(1-2)-α-L-rhamnopyranoside were evaluatedin vitroagainstSchistosoma mansoniadult worms and the bioactiven-hexane fractions of the mentioned species were also analyzed by GC-MS. Betulin was able to cause worm death percentage values of 25% after 120 h (at 100 μM), and 25% and 50% after 24 and 120 h (at 200 μM), respectively; besides the flavonoid quercetin 3-O-β-D-rhamnoside promoted 25% of death of the parasites at 100 μM.
