necrotizing meningoencephalitis caused by sarcocystis falcatula in bare-faced ibis (phimosus infuscatus).the infection by s. falcatula is commonly associated with respiratory disease in captive psittacine birds, with a few case reports of this protozoan causing encephalitis in wild birds. we describe the clinical, pathological, and molecular aspects of an infection by s. falcatula in a bare-faced ibis (phimosus infuscatus). clinically, wing paralysis and mild motor incoordination were observed. at necropsy, the telencephalic cortex showed multifocal to coalescing yellowish soft areas. histologicall ...201727915419
helminths assemblage of the bare-faced ibis, phimosus infuscatus (lichtenstein, 1823) (pelecaniformes: threskiornithidae), in southern brazil.birds act as hosts for a variety of parasites, many of these are unreported. the literature provides scant information on the helminth fauna of phimosus infuscatus. the presence of helminths were investigate in 28 birds from pelotas, capão do leão, and rio grande in rio grande do sul. the preparation and identification of helminths followed protocols. prevalence (p%), mean intensity of infection (mii), and mean abundance (ma) were estimated. the following helminths were found: hystrichis acantho ...201930810665
multilocus characterization of sarcocystis falcatula-related organisms isolated in brazil supports genetic admixture of high diverse sag alleles among the a previous study in brazil, six isolates of sarcocystis spp. recovered from budgerigars fed sporocysts excreted by opossums of the genus didelphis were characterized by means of sequencing fragments of gene coding cytochrome b (cytb), internal transcribed spacer 1 (its1), and surface antigen genes (sag2, sag3 and sag4). the isolates shared identical its1 and cytb sequences, but differed at sag2, sag3 and sag4: three allele variants of sag2, 3 allele variants of sag3 and 2 allele variants of s ...201829522766
pathology and morphometry of hystrichis acanthocephalicus (nematoda) from phimosus infuscatus (pelecaniformes) in southern brazil.species of hystrichis are parasite nematodes of the digestive tract of aquatic birds in south america, europe and asia. in brazil, hystrichis acanthocephalicus has been reported in phimosus infuscatus. there are few data on the morphometry of this species and there are no reports on pathological conditions that it causes. therefore, the purpose of this study was to report morphometric data from h. acanthocephalicus and describe the pathological effects of this parasite on the phimosus infuscatus ...201728146154
a new species selenonycha insperata n. sp. (acariformes: syringophilidae) from the bare-faced ibis phimosus infuscatus (lichtenstein) (pelecaniformes: threskiornithidae) as an example of host-switching event.a new quill mite species of the family syringophilidae (acariformes: prostigmata: cheyletoidea) is described from phimosus infuscatus (lichtenstein) (pelecaniformes: threskiornithidae) in argentina. selenonycha insperata n. sp. differs from other species of the genus selenonycha kethley, 1970 by the presence of wing-like cuticular projections of coxal fields iii-iv situated in front of trochanters (vs absence). an unexpected finding of this species on a bird of the family threskiornithidae (pele ...201728425038
chimaerula bonai sp. n. (cestoda: dilepididae) from the bare-faced ibis, phimosus infuscatus (lichtenstein) (aves: threskiornithidae) in paraguay.chimaerula bonai sp. n. is described from the small intestine of phimosus infuscatus (lichtenstein) in paraguay. the new species differs from the other two species of chimaerula bona, 1994, i.e., chinmaerula woodlandi (prudhoe, 1960) and chinmaerula leonovi (belogurov et zueva, 1968), mainly by the intermediate number of rostellar hooks (30-34 compared to 42-46 in the former and 20-22 in the latter), longer rostellar hooks (31-34 microm versus 26 microm and 19-21 microm, respectively), shorter c ...200011151955
