Host condition and individual risk of cowpox virus infection in natural animal populations: cause or effect?
No full textRecent studies have provided evidence that endemic pathogens may affect dynamics in animals. However, such studies have not typically considered that infected individuals might have a preceding underlying poor condition. We examined whether individuals in poor condition are more likely to become infected by an endemic pathogen, using as a system the dynamics of cowpox virus in field voles. With data from monthly sampled vole populations, a nested case-control study evaluated whether susceptible individuals with poorer condition had higher probabilities of contracting cowpox. The influence of condition was found to be considerable, especially for males. At times when a susceptible male with good body condition had a relatively low probability of becoming infected, a susceptible male with poor body condition was twice as likely to contract cowpox; if this male was also anaemic, the chances were almost quadrupled. We discuss the care needed when interpreting the findings of wildlife disease studies.Fil: Beldomenico, Pablo Martín. Universidad Nacional del Litoral.

Parasitologic examination and associated risk factors of domestic dogs at the domestic-wildlife interface in the Iberá wetlands Ecoregion, Argentina
No full textThe wildlife-domestic interface represents points of contact between wild animals and human-associated domestic animals, and provides opportunities for the dissemination and transmission of parasitic agents. Domestic dogs are reservoirs of parasitic agents, many of which are capable of infecting wild animals. To better investigate this potential risk at the Iberá wetlands eco-region, fecal samples from dogs present at the wildlife-domestic interface of two protected areas in Corrientes province, Argentina were examined. The prevalence of intestinal parasites and overall generic richness were examined and associations with age, sex, body condition, anthelmintic treatments and dog movement restriction were explored. From August-September 2017, questionnaires were carried out and fecal samples collected from 51 dogs at the interface zones. The overall estimated prevalence of gastrointestinal parasites was 63%. Nine genera of helminths and four protozoans were found in the examined dogs, many of which are known to infect wild carnivores and several have zoonotic potential. Ancylostoma and Isospora were the most prevalent genera. Freedom to roam was positively associated with prevalence and richness. From all dogs in our study, only a small proportion (17%) is subjected to some degree of movement restriction, while most dogs were free roaming. Veterinary health care and treatment was also extremely limited. The findings of this study revealed conditions of high prevalence of gastrointestinal parasites, lack of veterinary care and unrestricted roaming; all circumstances that suggest that dogs that live at these interface zones pose an infection risk to sympatric wildlife.Fil: Natalini, María Belén.

Philornis angustifrons Loew 1861
No full textPhilornis angustifrons (Loew, 1861) Hylemyia angustifrons Loew, 1861: 41. Syntypes male and female, not found (not in MCZ or ZMHB). Type-locality: Cuba. Described in the genus Hylemyia by Loew (1861), this species was based on material from Cuba. According to Carvalho et al. (2005), syntypes (male and female) were not found in MCZ or ZMHB. This species has been mistakenly recorded from Argentina by Garcia (1952). In synonymy with it is Mydaea anomala (Jaennicke, 1867), originally described as Mesembrina anomala, also from Cuba. This species is not the same as Mydaea anomala of Nielsen (1913) (= Philornis anomala of Aldrich 1923), which was described as P. nielseni by Dodge (1968). Both Stein (1918) and Dodge and Aitken (1968) mentioned that this species shows considerable intraspecific variation, e.g., in size and colour and, “likewise there is much variation in the puparia of such species as trinitensis, sanguinis and deceptivus, in general the larger puparia are dark brown with a small deep pit, whereas the smaller puparia are light brown with the pit broad and shallow (Dodge & Aitken 1968: 135). Other references to the names angustifrons and anomala in Argentina refer to anomala of Nielsen (1911, 1913). Even the synonymy of P. angustifrons (Loew) with anomala Nielsen was a confused interpretation by Aldrich (1923). The name P. angustifrons of Garcia (1952) also does not correspond to this species. He used this name, following Aldrich’s (1923) synonymy. This synonymy must not be accepted. Aldrich (1923) used Nielsen’s (1911, 1913) figures to represent the posterior spiracular slits of the puparia of M. torquans Nielsen and M. anomala of Nielsen (not Jaennicke) respectively. But on page 307, when discussing the synonymy with angustifrons Loew, he used the name anomala referring to M. anomala Jaennicke and not M. anomala of Nielsen. This is clear because he mentioned that “both species are described from Cuba, clearly referring to angustifrons Loew and anomala Jaennicke. Also, M. anomala of Nielsen 1913 (slits figured in his Fig. 3) could not be P. angustifrons Loew, as the posterior spiracular slits of this species are very sinuous, much more similar to those of P. pici, illustrated in his Fig. 5. Returning to Garcia’s (1952) angustifrons, his description, based on three females and one male (taken as larvae from a young chicken) from Monte Bello (Tucumán), is not very detailed, but differs from the true P. angustifrons in some aspects such as general colour of the thorax, r-m cross vein with a small mark and the large frons of the female with almost parallel margins. He described the female, but his Figure 1 (op. cit.: 279) shows the head of a male that is also not of P. angustifrons (as also observed by Dodge 1968). By mistake he mentioned the author of this species as (Jaenn., 1866) (see also Dodge 1968). Dodge (1968) considered that Garcia’s (1952) angustifrons could be anomala of Nielsen (1913), but the male head illustrated in his Figure 1 “fits neither nielseni nor angustifrons (p. 158). He doubtfully included Philornis angustifrons (Jaenn., 1866) of Garcia (1952) in synonymy with P. nielseni. Dodge and Aitken (1968) redescribed and Couri (1984) diagnosed P. angustifrons. The species shows intra-specific variation in colour, size, puparial concavity (depth and rugosity) and male surstyli (Dodge & Aitken 1968; Couri 1984).Published as part of Couri, Márcia S., Antoniazzi, Leandro R., Beldomenico, Pablo & Quiroga, Martin, 2009, Argentine Philornis Meinert species (Diptera: Muscidae) with synonymic notes, pp. 52-62 in Zootaxa 2261 on pages 56-57, DOI: 10.5281/zenodo.19076
Datos moleculares nuevos sobre Philornis (Diptera: Muscidae) subcutáneas del sur de Sudamérica sugieren la existencia de un complejo de especies
No full textThe taxonomic identification of species in the genus Philornis Meinert (Diptera: Muscidae) has been based primarily upon analysis of morphological characters. However, relying solely on morphology has led to frequent species misidentification. This has been empirically demonstrated when specimens identified morphologically as Philornis seguyi have been reclassified as Philornis torquans based on DNA sequences of the second ribosomal internal transcribed spacer (ITS2), showing that the morphologic distinction between these 2 species is extremely challenging. Herein, new molecular data on specimens assigned to P. torquans and P. seguyi from the type locality of P. seguyi (Misiones province, Argentina) were analyzed. The ITS2 sequences obtained differed from those previously reported for Philornis, increasing to 3 the number of documented genotypes of flies morphologically indistinguishable from P. torquans. These results strongly suggest that subcutaneous Philornis spp. from southern South America could represent a species complex (P. torquans complex).La identificación taxonómica de especies del género Philornis Meinert (Diptera: Muscidae) ha estado basada principalmente en el análisis de los
caracteres morfológicos. Sin embargo, el uso exclusivo de información morfológica ha llevado con frecuencia a errores en la identificación de las

P. torquans utilizando secuencias del segundo espaciador interno ribosomal transcrito (ITS2), lo que demuestra que la distinción morfológica entre
estas 2 especies es extremadamente complicada. En el presente trabajo se analizaron nuevos datos moleculares de especímenes identificados como
P. torquans y P. seguyi provenientes de la región reportada como localidad tipo para P. seguyi (provincia de Misiones, Argentina). Las secuencias
de ITS2 obtenidas fueron diferentes a aquellas previamente reportadas para otras especies de Philornis y se incrementa a 3 el número de genotipos
documentados de moscas morfológicamente indistinguibles asignadas a P. torquans. Estos resultados indican que los organismos de Philornis spp.

Sequence analysis of the internal transcribed spacer 2 (ITS2) from Philornis seguyi (García, 1952) and Philornis torquans (Nielsen, 1913) (Diptera: Muscidae)
No full textPhilornis Meinert, 1890 (Diptera: Muscidae) is a genus of Neotropical dipterans that parasitise birds. The currently used external morphological characters to distinguish between species within this genus present some limitations. We used the second internal transcribed spacer region (ITS2) of the rRNA gene as a molecular marker to differentiate adult specimens of Philornis identified morphologically as Philornis torquans and Philornis seguyi from different localities. Specimens identified as P. seguyi from Magdalena (Buenos Aires Province) showed an ITS2 sequence different from that for P. torquans, whereas all other specimens of P. seguyi had sequences identical to those for P. torquans. These findings do not necessarily confirm that specimens from Magdalena indeed belong to P. seguyi, nor that P. seguyi is a valid species. Instead, they alert us about the potential for species misidentification when using morphological characters alone. The use of molecular approaches to aid the identification of Philornis spp. will shed light on the systematics of this group. P. torquans is reported for the first time in Mendoza Province and Uruguay.Fil: Monje, Lucas Daniel. Consejo Nacional de Investigaciones Científicas y Técnicas.

Philornis seguyi Garcia 1952
No full textPhilornis seguyi Garcia, 1952 Mydaea anomala: Nielsen (1913: 251). Misidentification, not Mesembrina anomala Jaennicke, 1867. Philornis seguyi Garcia, 1952: 286. Holotype male, lost (formerly in MSPBA?) Type-locality: Argentina, Misiones. Philornis nielseni Dodge, 1968: 157 (new name for anomala Jaennicke sensu Nielsen 1913). Holotype male (ZMUC). Type-locality: Argentina. Syn. nov. The species can be recognised as follows: body length 7–9mm; frons yellowish, eye with a faint golden reflection; width of frons at level of anterior ocellus 0.07–0.09 of head width in male and 0.13–0.14 in female; antenna and palpus yellow; cheek yellow-haired; scutum brown with greyish pollinosity, with the quadrivitatte pattern typical of the genus; wing clear, some specimens with a faint brown spot on r-m cross vein; legs yellow in male and somewhat brown in female; hind tibia on anterodorsal surface with 2–4 setae on middle third, anteroventral surface with 3–4 fine bristles on middle third. Abdomen brown with greyish pollinosity. Larva intradermal. Puparium brown, cylindrical, posterior end deep with rugose margins; spiracular slits “U or “V shaped. (Figures in Couri et al. 2005). Couri et al. (2005) described the larva, puparium, adult male and the terminalia of both sexes, based on material collected in Buenos Aires province and identified using the original description of Garcia (1952). The slight differences in size and colour of the legs described in P. nielseni by Dodge (1968) are here considered as intraspecific variation, as in other Philornis species. The synonymy of P. nielseni with P. seguyi is herein proposed as there is no justification to consider them as separate species. The species was found among the material recently collected in Argentina as below. Material examined: (MQ): Argentina, Santa Fe, Santa Fe, 3138 'S 6091 'W. Ex nest of Troglodytes aedon: 27 males and 44 females reared from larvae. (LRA): 4 adults reared from larvae.

Host-parasite association between Didelphis albiventris (Didelphimorphia: Didelphidae) and Ixodes loricatus (Acari: Ixodidae) in their southern ranges
No full textThe parasitism of Ixodes loricatus Neumann on white-eared opposum, Didelphis albiventris Lund, was analysed in the southern ranges of both. In central Argentina, 118 wild opossums were captured from 2005 to 2012. Adults of I. loricatus were collected (prevalence = 66.1%, mean = 7.03, median = 4), but no immature stage. Tick infestation was not affected by sex (p = 0.27) or age (p = 0.37) of hosts. In line with previous studies about seasonality of larvae and nymphs of I. loricatus, adult tick infestation showed no seasonal trend. This lack of seasonal pattern of infestation for all parasitic stages of I. loricatus may indicate a life cycle governed by nidicolous behaviour, in such a way that this habit would contribute to minimize the influence of external environmental variables. The tick sex ratio was female biased, with two females per one male (p = 0.002). The absence of I. loricatus immatures on D. albiventris suggests that in the study region there is clear segregation of immatures in rodents and adults in marsupials.Fil: Tarragona, Evelina Luisa.

Experimental testing of reciprocal effects of nutrition and parasitism in wild black capuchin monkeys
No full textNutritional stress may predispose individuals to infection, which in turn can have further detrimental effects on physical condition, thus creating an opportunity for reciprocal effects between nutrition and parasitism. Little experimental investigation has been conducted on this "vicious circle" hypothesis in wild animals, especially under natural conditions. We evaluated the reciprocal effects of nutritional status and parasitism using an experimental approach in two groups of wild black capuchin monkeys (Sapajus nigritus). Across two consecutive winters, we collected faecal samples from identified capuchins to determine presence and load of gastrointestinal helminthes, and measured individual body mass as a proxy of physical condition. Food availability was manipulated by provisioning monkeys with bananas, and parasite burdens by applying anti-parasitic drugs to selected individuals. We found no effect of anti-parasitic drugs on physical condition, but parasite loads decreased in response to high levels of food availability. Our results represent the first experimental evidence that the nutritional status may drive parasite dynamics in a primate.Fil: Agostini, Ilaria.

Variability of Calodium hepaticum eggs from sigmodontine host species through geometric morphometric analysis
No full textCalodium hepaticum is a zoonotic nematode with a worldwide distribution. Although the host range of C. hepaticum includes a wide spectrum of mammals (including humans), this parasite is predominantly associated with the families Muridae and Cricetidae. Several Sigmodontinae species from Argentina were found to be infected by C. hepaticum, with a high prevalence in Akodon azarae. The present study focuses on C. hepaticum eggs from natural infection of three species of sigmodontine rodents from Argentina. Eggs were genetically characterized (intergenic 18S rRNA region). The objectives of this work are: (i) to propose a new analytical methodology; and (ii) to morphologically characterize C. hepaticum eggs, from three Sigmodontinae species (A. azarae, Calomys callidus and Oligoryzomys flavescens). Analyses were made by the Computer Image Analysis System based on the new standardized measurements and geometric morphometric tools. The resulting factor maps clearly illustrate global size differences in the parasite eggs from the three Sigmodontinae species analysed. The degree of similarity between egg populations was assessed through pairwise Mahalanobis distances, showing that the largest distances were detected between parasite eggs from C. callidus and O. flavescens. Herein, the phenotypical plasticity of C. hepaticum eggs is shown. Significant positive correlations were obtained between each egg parasite principal component 1 and rodent corporal characteristics: weight; liver weight; rodent length; and rodent body condition. The usefulness of the geometric morphometric analysis in studies of the relationship between C. hepaticum and its host must be highlighted. The high prevalence observed in A. azarae, associated with the wide size range of the parasite eggs evidenced by principal component analysis, suggests A. azarae to be the Sigmodontinae host species that plays the most important role as reservoir host for C. hepaticum in the New World.Fil: Fantozzi, María Cecilia.
