Spirura delicata sp. n. (Spiruridae, Spirurinae) from Leontocebus mystax (Callithrichidae) and a check list of other Nematodes of some brazilian primates

Abstract

Spirura delicata sp. n. from Leontocebus mystax (Six) is proposed and compared to S. guianensis (Ortlepp, 1924) Chitwood, 1938, S. michiganensis Sandground, 1935 and S. nayarani Mirza & Basir, 1938. Their differentiation is based mainly on the size and shape of spicules. Identification of nematode samples recovered from primates along 60 years and presently deposited in the Oswaldo Cruz Helmintological Collection is provided herein through a check list. Some of them are reported in new hsots and/or geographical regions

Spirura carajaensis n. sp. (Nematoda: Spiruridae), parasite of Proechimys roberti Thomas 1901 (Rodentia: Echimyidae) from Brazilian Amazon

“…has 10 pairs; 4 pairs are pre-cloacal pedunculated papillae, 4 pairs are post-cloacal pedunculated papillae and 2 sessile pairs are at the end of the tail in addition to a pair of phasmids. This characteristic differs from the description of S. delicata, which has a total of 9 pairs of papillae, of which 4 pairs are pedunculated and pre-cloacal, 2 pairs are pedunculated and post-cloacal and 3 pairs are sessile on the tip of the tail (Vicente et al, 1992). There is no agreement regarding the number of caudal papillae in the description of S. guianensis.…”

“…An important and common characteristic of the species described in North America is the presence of 8 to 12 pairs of pre-cloacal papillae (Sandground, 1935;Quetin and Krishnasamy, 1975;Peralta-Rodriguez et al, 2012). In South America, there are only 2 species of the genus, which were described from mammalian hosts: Spirura guianensis, (Ortlepp, 1924;Chitwood, 1938) (= Spirura tamarini Cosgrove et al, 1963), a parasite of primates and marsupials, and Spirura delicata (Vicente et al, 1992), a parasite of Leontocebus mystax. Spirura carajaensis n. sp.…”

“…In Brazil, only 2 of these genera have been recorded as parasites of mammals: Protospirura and Spirura (Vicente et al, 1977), and the authors list three species of the genus Spirura that are parasites of Brazilian mammals. However, only Spirura delicata (Vicente et al, 1992) was identified as a primate parasite in the Amazon biome, and Spirura guianensis (Ortlepp, 1924) (syn. Spirura tamarini Cosgrove et al, 1963) was identified to infect marsupials in the Atlantic Forest biome (Amato et al, 1976).…”

Trypanoxyuris (Paraoxyuronema)lagothricis (Nematoda: Oxyuridae) in Lagothrix cana (Primates: Atelidae) from Brazil

“…have been reported in non-human primates since the first quarter of the twentieth century, and six species of these parasites were already confirmed parasitizing 10 species of hosts: (1) Trypanoxyuris (Paraoxyuronema) brachytelesi (Artigas, 1936) (Travassos, 1925) described from S. sciureus (TRAVASSOS, 1925;ARTIGAS, 1936;HUGOT, 1984HUGOT, , 1985VICENTE et al, 1997;VALENÇA et al, 2000;AMATO et al, 2002;MARTINS et al, 2008;SOUZA et al, 2010). Moreover, unidentified species of Trypanoxyuris were recorded in A. caraya and S. sciureus (VICENTE et al, 1992) and eggs of these parasites were found in the feces of Aotus azarai infulatus (Kuhl, 1820) (Primates: Aotidae) and A. guariba clamitans (SOUZA JÚNIOR et al, 2008;BARROS MONTEIRO et al, 2009). Despite these previous reports, the amount of species of Trypanoxyuris that occurs in Brazilian primates may be higher than previously recorded considering the richness of primate species in Brazil and their helminths, which have not been comprehensively studied.…”

Redescription of Spirura guianensis (Nematoda: Spiruridae) from a rare South American Gracile Opossum

“…The anterior region presents a developed cuticular ring and cephalic structures, characterized as teeth or denticles described by LM (Ortlepp, 1924;Cosgrove et al, 1963;Quentin, 1973;Vicente et al, 1992;Alvarez et al, 1995). Our SEM analyzes show that these cephalic structures are not teeth or related structures.…”
