Placentation in the Amazonian manatee (Trichechus inunguis)
Carter, Anthony M.; Miglino, Maria Angelica; Ambrósio, Carlos Eduardo; dos Santos, Tatiana Carlesco; Weber Rosas, Fernando CesarEvidence from several sources supports a close phylogenetic relationship between elephants and sirenians. To explore whether this was reflected in similar placentation, we examined eight delivered placentae from the Amazonian manatee using light microscopy and immunohistochemistry. In addition, the fetal placental circulation was described by scanning electron microscopy of vessel casts. The manatee placenta wa...
Body weight-length relationships in giant otters (Pteronura brasiliensis) (Carn...
Weber Rosas, Fernando Cesar; Rocha, Carla Soares da; Mattos, Gália Ely de; Lazzarini, Stella MarisFew giant otters (Pteronura brasiliensis) have been measured and weighed and its actual size is controversial in the literature. This study presents the weight-length relationship of Amazonian giant otters using 15 captive individuals. The maximum length and weight were 163cm and 22.5kg, and 162cm and 28.8kg, for the males and females, respectively. The weight-length relationships were not significantly differe...
Antifungal resistance and virulence among Candida spp. from captive amazonian m...
Sidrim, José Júlio Costa; Carvalho, Vitor Luz; Castelo-Branco, Débora de Souza Collares Maia; Brilhante, Raimunda Sâmia NogueiraThis work aimed at evaluating the antifungal susceptibility and production of virulence factors by Candida spp. isolated from sirenians in Brazil. The isolates (n = 105) were recovered from the natural cavities of Amazonian and West Indian manatees and were tested for the susceptibility to amphotericin B, itraconazole, and fluconazole and for the production of phospholipases, proteases, and biofilm. The minimum...
Amblyomma parvum A PARASITE OF Dasypus kappleri IN THE STATE OF AMAZONAS, BRAZIL
Mullins, Maria Cristina; Lazzarini, Stella Maris; Picanço, Márcia Cristina de Lima; Serra-Freire, Nicolau MauésAmblyomma parvum is widespread distributed because of a wide range of animals hosts and has been cited as a parasite of humans and domestic animals. This work reports the occurrence of A. parvum on a new host species, Dasypus kappleri, and in a new geographical zone, the State of Amazonas. Three male of Amblyomma parvum were obtained from a dead long-nosed armadillo (Dasypus kappleri) confiscated from a hunter ...
