“…4). The same pattern was remarked by Tamaru et al (2015) and Sakaguchi et al (2020) for species of avian Capillaria which could not be easily discriminated on morphological grounds, although their genetic characterization of 18S rDNA clearly differentiated them from one another (Sakaguchi et al 2020). These distances are then not completely unexpected, since Moravec (1982) remarked that further studies will apparently result in breaking up the present genus Capillaria into additional independent genera.…”

“…4 clustered robustly according to the generic arrangement of Moravec (1982). The same was observed in the surveys of Tamaru et al (2015), and Sakaguchi et al (2020). In these latter works, the genus Baruscapillaria was only represented by isolates of B. obsignata since until then no sequences were available for other species of the genus.…”

“…Therefore, we conducted a phylogenetic analysis including the newly obtained sequences of B. spiculata in order to confirm the taxonomic status and generic assignment of this latter species. With this aim, we largely relied on the work of Tamaru et al (2015), and that of Sakaguchi et al (2020) who compared several 18S rDNA sequences of different capillariid species parasitizing mainly birds and mammals. The BLAST searching revealed that our Fig.…”

Redescription and molecular characterization of Baruscapillaria spiculata (Nematoda: Capillariidae) parasitizing the Neotropic cormorant Phalacrocorax brasilianus from two Argentinian lagoons

Two species of intestinal Capillariidae were hitherto known from the Neotropic cormorant Phalacrocorax brasilianus, Baruscapillaria spiculata (Freitas, 1933), and Baruscapillaria appendiculata (Freitas, 1933). The original descriptions are very short and brief, and further reports of both species are scarce and/or confusing. This paper provides a morphological redescription and molecular characterization, based on the partial 18S rDNA gene, of B. spiculata specimens parasitizing the Neotropic cormorant in two continental lagoons from Buenos Aires province, Argentina. Both morphological and morphometrical differences between B. spiculata and B. appendiculata are highlighted on the examination of available type material. Additionally, two previous reports of B. appendiculata from Mexico and Brazil are discussed. A phylogenetic analysis conducted on specimens of B. spiculata and 46 other capillariid isolates available from the GenBank demonstrated a sister-taxon relationship between our specimens and the type species of Baruscapillaria. But, at the same time, significant genetic distances between both taxa showed an interesting variability of the genus Baruscapillaria. The probable division of this genus into multiple genera could probably be confirmed through integrative studies including more species.

“…Microscope slides were prepared, and morphological observations and morphometric measurements were performed using biological light microscopes (10–400×) [ 24 , 25 ]. Helminths were identified to species on the basis of morphological and morphometric characterization of specimens, using standard taxonomic references [ 26 , 27 , 28 , 29 , 30 ] and original works [ 4 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. In the case of parasite specimens that were mechanically damaged when the digestive tract was opened with scissors and or when the mucosa was scraped, the morphological characters necessary for species identification were not visible.…”

The aim of this study was to describe the morphology and means of identification of helminths in native partridges (65) and introduced pheasants (32) in Poland and to determine the level of intestinal infection of these birds by helminths using parasitological and ecological indices. The birds were acquired during the hunting season in the years 2015–2017. Nematodes, Capillaria phasianina, cestodes, Railietina friedbergeri, and one trematode, Brachylaima sp. were recorded for the first time in partridges in Poland. Our findings indicate that parasites are more prevalent in pheasants (prevalence 70.4%) than in partridges (prevalence 50.0%). The component community and infracommunity of parasites of partridges are more diverse (Simpson’s diversity index: 0.63 and mean Brillouin diversity index: 0.10 ± 0.17) and less dominated by a single parasite species (Capillaria sp., Berger-Parker dominance index: 0.53) than the pheasant parasite community (Simpson’s diversity index: 0.07, mean Brillouin diversity index: 0.005 ± 0.02, dominant species Heterakis gallinarum, Berger-Parker dominance index: 0.96). There were statistically significant differences between partridges and pheasants in the Brillouin diversity index and in the prevalence of Heterakis gallinarum (55.6% in pheasants vs. 19.0 in partridges). There were significant differences between wild and farmed partridges in the prevalence of infection by Capillaria sp. (4.3% vs. 37.5%) and H. gallinarum (39.1 vs. 6.2%). In conclusion, the pheasant was shown to be a reservoir, carrier, and shedder of nematodes, which may increase the risk of infection in partridges.

“…Research on nematodes to evaluate soil and environmental health in Indonesia is still limited. Nematode studies in Indonesia focus on plant-parasitic nematodes (Budiman et al, 2020;Djiwanti, 2019;Handayani et al, 2020;Kurniawati et al, 2020;Lisnawita et al, 2012;Mirsam et al, 2020;Mutala'liah et al, 2018), parasites in vertebrates (Ahmad & Tiffarent, 2020;Baihaqi et al, 2019;Khoirani et al, 2020;Sakaguchi et al, 2019), and nematode ecology (Krashevska et al, 2019). Therefore, this research needs to be carried out considering the great benefits and advantages of nematodes as bioindicators and the limited research on Pertanika J. Trop.…”

Soil biota is very diverse and contributes widely to ecosystem services that are important in the sustainable function of natural and managed ecosystems. Knowing the condition of the soil food web through the communities that inhabit it is necessary to assess the productivity of the soil. Nematode communities in the soil food web can be used as indicators because of their high abundance, and they inhabit various trophic levels, and participate in several important processes in the soil. The soil food web condition from three locations (Agr1, Agr2, Agr3) through the nematode functional index was evaluated using the maturity index (MI), the maturity index 2-5 (MI-25), the plant-parasitic index (PPI), the channel index (CI), the enrichment index (EI), the structure index (SI), and the basal index (BI). Nematode diversity was evaluated using Simpson’s index of diversity, dominance, and evenness. The MI and MI2-5 scores indicated that Agr3 (3.81) had an undisturbed food web, while Agr2 (2.88 and 3.0) and Agr1 (2.5 and 2.51) were in a moderate condition with minor disturbances. Fauna profile analysis using SI and EI shows that Agr3 and Agr1 had an undisturbed soil food web, and Agr2 was in enriched conditions. CI results found that Agr1 and Agr3 had a fungal decomposition pathway while Agr2 had a bacterial decomposition pathway. We concluded from this research, that prospect of the nematode community to serve as a collection of biological indicator data in assessing soil or ecosystem health can be considered in further research.
