Sobre uma hemogregarina da gambá: Haemogregarina didelphydis n. sp.

Molecular survey of tick-borne pathogens in small mammals from Brazilian Amazonia

“…However, to the best of our knowledge, here we provide the first report on the molecular detection of Hepatozoon in D. marsupialis. A common species of Hepatozoon, namely Hepatozoon didelphydis, that infects neotropical marsupials (such as D. albiventris, D. aurita, D. marsupialis, Philander opossum, and Metachirus nudicaudatus) has already been described in French Guiana (THOISY et al, 2000), Colombia (AYALA et al, 1973), and Brazil (SILVA & ARANTES, 1916). However, these reports were based only on morphological analyses through microscopical observations of blood smears, and could therefore represent different Hepatozoon species (MERINO et al, 2008).…”

A Sarcocystid Misidentified as Hepatozoon didelphydis: Molecular Data from a Parasitic Infection in the Blood of the Southern Mouse Opossum (Thylamys elegans) from Chile

“…Uninfected erythrocytes were considered as perfectly round and only one diameter was measured. a Data from d'Utra e Silva and Arantes (1916) in which sample size was not given. 537 seven isolates were identical.…”

“…Hepatozoon didelphydis was first described from the big-eared opossum (Didelphys aurita) by d'Utra e Silva and Arantes (1916) as Hemogregarina didelphydis and later transferred to the genus Hepatozoon by Wenyon in 1926 (see Smith 1996). The parasite found infecting erythrocytes of the southern mouse opossum in this study is morphologically similar to that described by d'Utra e Silva and Arantes (1916) and presents the same characteristics of pleomorphism and color: fine alveolar pale blue cytoplasm containing a few red granules and a centrally placed nucleus lacking a clearly defined nuclear membrane ( Fig. 1-3).…”

“…Several species of Sarcocystis infecting American opossum species are known (Rosenthal et al 2001), but to our knowledge none from the southern mouse opossum (T. elegans). Hepatozoon species, probably H. didelphydis, have been reported infecting a number of neotropical marsupials, including Didelphys marsupialis, Philander opossum, and Metachirus nudicaudatus (Ayala et al 1973;Deane and Deane 1961;de Thoisy et al 2000;d'Utra e Silva and Arantes 1916;Garnham and Lewis 1958;Regendanz Fig. 4.…”

“…However, other species of American opossums have been found to be infected by several parasitic protists, including species of Sarcocystis (Rosenthal, Lindsay, and Dubey 2001), Leishmania (Santiago et al 2007), andHepatozoon (de Thoisy et al 2000). Hepatozoon didelphydis is a pleomorphic species reported from several American marsupials, but since the original description of the species as Hemogregarina didelphydis (d'Utra e Silva and Arantes 1916), its life cycle has never been determined.…”
