Nematodes of Amazonian vertebrates deposited in the Helminthological Collection of the Oswaldo Cruz Institute with new records

Abstract

In this work 28 nematode samples from amphibians, reptiles, birds and mammals captured in the State of Amazonas, Brazil, and deposited in the Helminthological Collection of the Oswaldo Cruz Institute between 1927 and 1955, were studied. Oswaldocruzia sp. and Physaloptera sp. (from amphibians), Skrjabinura spiralis Gnedina, 1933 (from birds), Mammomonogamus laryngeus (Railliet, 1899) Ryzikov, 1948 and Trichuris gracilis (Rud, 1819) Hall, 1916 (from mammals) are reported from the State of Amazonas for the first time. Oswaldocruzia mazzai Freitas & Lent, 1935, Oswaldocruzia lopesi Travassos, 1938, Aplectana membranosa (Schneider, 1866) Miranda, 1924, Physaloptera retusa Rudolphi, 1819, Capillaria sp., and Cosmocerca sp. (from amphibians), Diplotriaena bargusinica Skrjabin, 1917 and Porrocaecum sp. (from birds), Dipetalonema graciliformis Freitas, 1964 and Monodontus sp. (from mammals) represent new hosts and a new geographical distribution. Kalicephalus subulatus Molin, 1861 (from reptiles) is reported from a new host

Helminths of Molothrus bonariensis (Gmelin, 1789) (Passeriformes: Icteridae) from southernmost Brazil

“…Pinto et al (1997) reported the presence of D. bargusinica for the first time in Cyanocorax cyanomelas (Vieillot, 1818) (Corvidae) in the state of Mato Grosso do Sul, from samples collected between 1921 and 1925 in scientific expeditions conducted in Brazil, without informing the number of birds examined or their indexes. Gonçalves et al (2002) found D. bargusinica in the body cavity of three individuals of Psarocolius bifasciatus (Spix, 1824) (Icteridae) in the state of Amazonas and Carvalho et al (2007) in air sacs of Paroaria dominicana (Linnaeus, 1758) (Emberizidae) (n = 34), P = 8.8%, MA = 0.32 and MI = 3.66, in the state of Bahia. Anderson (1962), performed experimental infection with D. bargusinica in wild birds (Turdidae and Icteridae) and described details of its biological cycle which uses grasshoppers (Orthoptera) as intermediate hosts.…”

New records for helminths of hystricognath rodents from the middle and high Rio Negro microregion, State of Amazonas, Brazil

“…Remarks: taking into account that no males of this species are available so far (CAMERON & REESAL 1951, GONÇALVES et al 2002, the presently studied samples were identified to Trichuris gracilis considering that this species is the only of the genus de- (1819), also considering the former species as Trichuris gracilis var. gracilis.…”

“…trinitatae, suggesting that variations may not be taken into account and that differences are due to the physiological conditions of the host and to a process of parasite adaptation. This species was previously referred in Dasyprocta leporina (Linnaeus) from Manaus, State of Amazonas, Brazil (GONÇALVES et al 2002).…”

“…Moreover, the positive and rising concern related to the maintenance of the biodiversity of the Amazon forest by means of laws to protect the environment and control the studies in these areas has also to be taken into account. Even though some researchers (VICENTE 1964, PEREIRA & MACHADO FILHO 1968, GOMES & PINTO 1978, PINTO & GOMES 1976, 1980, 1984, THATCHER 1991, GONÇALVES et al 2002 had contributed to the knowledge of helminth parasites of non-human hosts, there is a lot more to be investigated so far in the Amazon region.…”
