The duplex real-time PCR developed here represents a method that permits simultaneous detection and differentiation of B. burgdorferi s.l. and B. miyamotoi in environmental and potentially clinical samples.
Twenty-four species of chewing lice of the genus Myrsidea Waterston, 1915 (Phthiraptera: Menoponidae) from Neotropical Suboscines (Passeriformes: Formicariidae, Furnariidae, Pipridae, Thamnophilidae, Tityridae, Tyrannidae) are recorded and discussed. They include: eight new species which are described and illustrated (Myrsidea capeki new species ex Chiroxiphia caudata; Myrsidea leptopogoni new species ex Leptopogon superciliaris; Myrsidea leucophthalmi new species ex Automolus leucophthalmus; Myrsidea pachyramphi new species ex Pachyramphus polychopterus; Myrsidea philydori new species ex Philydor rufum; Myrsidea pyriglenae new species ex Pyriglena leucoptera; Myrsidea scleruri new species ex Sclerurus scansor and Myrsidea zuzanae new species ex Furnarius rufus), as well as nine previously known species with additional data on intraspecific morphological variability, host associations and geographical distribution
Eleven species of lice of the genus Myrsidea Waterston, 1915 (Phthiraptera: Menoponidae) from passerine birds (Passeriformes: Cardinalidae, Fringillidae, Thraupidae) in the Neotropical Region are recorded and discussed. They include three new species with hosts in the family Thraupidae from Paraguay, which are described and illustrated: Myrsidea flaveolae new species ex Sicalis flaveola, Myrsidea habiae new species ex Habia rubica, and Myrsidea sayacae new species ex Thraupis sayaca. Five other previously known Myrsidea species are included with new data on intraspecific morphological variability, hosts associations and geographical distribution, as follows: Myrsidea coronatae, M. lightae, M. rufi, M. seminuda, and M. violaceae. Three further species are recorded at genus level only due to lack of adequate material. A 379 bp portion of the mitochondrial cytochrome oxidase I (COI) gene was sequenced in order to assess relative genetic divergence among Myrsidea populations. The application of intra-and interspecific sequence divergences as predictor of species boundaries in the taxonomy of this megadiverse genus is discussed.
The new species Myrsidea alexanderi is described and illustrated ex Pheugopedius maculipectus (Troglodytidae) from Honduras. Redescriptions and illustrations are given for both sexes of Myrsidea chiapensis ex Calocitta formosa from Costa Rica, and the male of M. dissimilis ex Progne chalybea from Brazil. Also, seven other previously known species or subspecies of the louse genus Myrsidea are recorded and discussed from passerine birds of the Neotropical Region, as follows: Myrsidea antiqua, Myrsidea balteri, Myrsidea diffusa, Myrsidea nesomimi borealis, Myrsidea paleno, Myrsidea psittaci and Myrsidea serini. Our data increase knowledge of intraspecific morphological variability within these species, and also of their host and geographical distribution. New host-louse associations are: Agelaioides badius for M. psittaci; Basileuterus culicivorus and Myiothlypis leucoblephara for M. paleno; Mimus saturninus for M. nesomimi borealis; and Icterus dominicensis and Molothrus rufoaxillaris for Myrsidea sp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
