Diversidad y distribución de las especies de Mallophaga (Insecta) en Aves y Mamíferos de la Comunidad de Madrid

The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants’ carcasses collected from 2001 to 2008 in Antofagasta, Biobío, and Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites. Ectoparasites collected were cleared and mounted for identification under a microscope. Fecal samples were also evaluated to determine the presence of protozoan parasites employing a flotation technique. A total of 44 (42.5%) of birds were infested with at least one ectoparasite species, while 77 (96.25%) were carrying endoparasites. No protozoan forms were found after examination. Most prevalent endoparasite species found were Contracaecum rudolphii s. l. (72/80, 90%), followed by Pectinopygus gyroceras (33/80, 41.25%), and Profilicollis altmani (26/80, 32.5%). This is the first report of P. altmani, Baruscapillaria carbonis, Avioserpens sp., Cyathostoma (Cyathostoma) phenisci, and Eidmaniella pelucida in the Neotropic cormorant. These findings also expand the distributional range of Andracantha phalacrocoracis, Paradilepis caballeroi, Hysteromorpha triloba, and P. gyroceras to Chile.

“…With respect to A. rollandii, it was only previously reported in Rollandia rolland chilensis (Lesson) in Argentina (CASTRO & CICCHINO, 2000). In contrast, P. dolium is a cosmopolitan species that parasitizes Podiceps ruficollis, P. auritus, P. grisegena, P. cristatus, P. nigricollis, Podilymbus podiceps, Aechmophorus occidentalis, and Tachybaptus ruficollis in Europe, Africa, India, Asia and North America (PRICE, 1974;MARTÍN MATEO, 2006;VAS et al, 2012;DIK & HALAJIAN, 2013;GALLOWAY et al, 2014;JAŁOSZYŃSKI et al, 2014). In South America, P. dolium has been described as a parasite of P. podiceps in Argentina, R. rolland chilensis in Chile and Argentina, P. taczanowskii in Peru, and P. occipitalis in Bolivia (PRICE, 1974;CICCHINO, 2011).…”

A total of 97 southern silvery grebes (Podiceps occipitalis), which died as the result of an oil spill on the coast of central Chile, were examined for ecto- and endoparasites. Two lice species including Aquanirmus rollandii (Philopteridae) and Pseudomenopon dolium (Menoponidae) were found from 6.2% (6/97) of birds. In 91.7% (89/97) of cases, grebes were infected with some kind of helminths. Three species of gastrointestinal helminths were detected: Eucoleus contortus (Nematoda), Profilicollis bullocki (Acanthocephala), and Confluaria sp. (Cestoda). In addition, Pelecitus fulicaeatrae (Nematoda) was removed from the tibiotarsal-tarsometatarsal articulation in 13.4% (13/97) of the specimens examined. To our knowledge, these are the first records of A. rollandii, E. contortus, and Confluaria sp. as parasites of P. occipitalis. In addition, these findings expand the distributional range of A. rollandii, E. contortus, P. fulicaeatrae, and Confluaria sp. to Chile.

“…Brueelia cyclothorax and M. quadrifasciata have been recorded on house sparrows in Europe and North America (Brown & Wilson, 1975;Price et al, 2003;Martín-Mateo, 2006, and Asia (Saxena et al, 2007;Moodi et al, 2013). The present records reflect their close relationship with the house sparrow, as they can be found across the invaded areas, such as in South America (Hernandes & Flechtmann, 2020).…”

“…Menacanthus eurysternus is a species complex which, unlike most other lice, can be found on hosts from various families of Passeriformes -e.g., Corvidae, Fringillidae, Icteridae, Prunellidae, Remizidae, Sturnidae, and Turdidae, as well as on Piciformes around the world (Price et al, 2003;Galloway, 2005;Martín-Mateo, 2006;Fairn et al, 2014;Galloway et al, 2014), with over 170 avian species counted as hosts (Price, 1975;Price et al, 2003). In terms of house sparrows, this parasite has been recorded in Europe and North America (Brown & Wilson, 1975;Price et al, 2003;Martín-Mateo, 2006;Byers & Proctor, 2013), and New Zealand (Galloway, 2005;Palma 2017). In Chile, in addition to the present record, this generalist louse has been isolated only on the austral thrush (González-Acuña et al, 2006;Llanos-Soto et al, 2019).…”

Parasitic fauna of the invasive house sparrow (Passer domesticus) from Ñuble region, Chile: an example of co-introduced parasites

et al. 2021

Invasive species impact native wildlife in several ways, as they compete for resources and may transmit their specific pathogens. However, the potential consequences of co-introduced parasites are not fully understood. While the house sparrow (Passer domesticus) was introduced in Chile about a century ago, no data are available regarding its parasites. Thus, the aim of the present study was to determine the parasitic fauna of this avian invader and to determine whether there are co-introduced/co-invasive parasites shared with native birds. One hundred and eight birds were collected from three different localities in the Ñuble region of Chile, and a complete parasitic necropsy was performed in the laboratory. Twenty-three (21.3%) were parasitized by six arthropod species and four (3.7%) were parasitized by two helminth species. Four out of eight taxa are reported for the first time in Chile; among them, three arthropod parasites and the tapeworm, Anonchotaenia globate, are considered as co-introduced parasites. Only A. globata is a potential co-invasive parasite given its low degree specificity in terms of its definitive hosts. Future research should examine whether additional co-introduced/co-invasive parasites have been brought by the house sparrow, and what their potential consequences might be on the health of native birds in Chile.
