Abstract Background In South and Central America, Plasmodium malariae/Plasmodium brasilianum, Plasmodium vivax, Plasmodium simium, and Plasmodium falciparum has been reported in New World primates (NWP). Specifically in Costa Rica, the presence of monkeys positive to P. malariae/P brasilianum has been identified in both captivity and in the wild. The aim of the present study was to determine the presence of P. brasilianum, P. falciparum, and P. vivax, and the potential distribution of these parasites-infecting NWP from Costa Rica. Methods The locations with PCR (Polymerase Chain Reaction) positive results and bioclimatic predictors were used to construct ecological niche models based on a modelling environment that uses the Maxent algorithm, named kuenm, capable to manage diverse settings to better estimate the potential distributions and uncertainty indices of the potential distribution. Results PCR analysis for the Plasmodium presence was conducted in 384 samples of four primates (Howler monkey [n = 130], White-face monkey [n = 132], Squirrel monkey [n = 50], and red spider monkey [n = 72]), from across Costa Rica. Three Plasmodium species were detected in all primate species (P. falciparum, P. malariae/P. brasilianum, and P. vivax). Overall, the infection prevalence was 8.9%, but each Plasmodium species ranged 2.1–3.4%. The niche model approach showed that the Pacific and the Atlantic coastal regions of Costa Rica presented suitable climatic conditions for parasite infections. However, the central pacific coast has a more trustable prediction for malaria in primates. Conclusions The results indicate that the regions with higher suitability for Plasmodium transmission in NWP coincide with regions where most human cases have been reported. These regions were also previously identified as areas with high suitability for vector species, suggesting that enzootic and epizootic cycles occur.

Retroviral Infections

ABSTRACT Host cell factors modulate retroviral infections. Among those, cyclophilin A (CypA) promotes virus infectivity by facilitating virus uncoating or capsid unfolding or by preventing retroviral capsid interaction with cellular restriction factors. In Aotus species, a retrotransposed copy of CypA inserted into the tripartite motif 5 (TRIM5) gene encodes a fusion protein which may block human immunodeficiency virus type 1 by targeting the incoming virus to ubiquitin-ligated degradation or by interfering with normal uncoating of the incoming particle, rendering those monkeys resistant to infection. In this study, we have extensively analyzed representative specimens from all New World primate genera and shown that the retrotransposed CypA copy is only present in Aotus. We have shown that this inserted copy diverged from its original counterpart and that this occurred prior to Aotus radiation, although no positive selection was observed. Finally, our data underscores the need for a precise taxonomic identification of primate species used as models for retroviral infections and novel antiviral approaches.

Abstract The ways that forest edges may affect animal vocalization behaviour are poorly understood. We investigated the effects of various types of edge habitat on the loud calls (howls) of a folivorous-frugivorous primate species, Alouatta palliata, with reference to the ecological resource defence hypothesis, which predicts that males howl to defend vegetation resources. We tested this hypothesis across four forest zones — interior, riparian, anthropogenic, and combined forest edges — in a riparian forest fragment in Costa Rica. We predicted vegetation and howling would differ between forest zones, with riparian and interior zones showing the highest values and anthropogenic edge the lowest. Our results indicated that vegetation was richer and howling longer in riparian and interior zones compared to combined and anthropogenic edges, supporting the resource defence hypothesis and providing some of the first evidence in animal communication scholarship for differences in behavioural edge effects between natural riparian and anthropogenic edges.

GB virus B (GBV-B) is a flavivirus that is related closely to hepatitis C virus (HCV) and induces an acute hepatitis when inoculated into several species of New World primates. Common marmosets (Callithrix jacchus) are a widely available, non-endangered primate species that is susceptible to GBV-B infection and develops a characteristic acute hepatitis. Here, animals were found to be susceptible to serially passaged serum and GBV-B transcripts. Hepatic pathology and peripheral viraemia could be quantified biochemically, immunophenotypically and morphologically, and persisted for periods of up to 6 months in some animals. Hepatitis was characterized by a marked influx of CD3+ CD8+ T lymphocytes and CD20+ B cells within the first 2 months of primary infection. The results of this study document the marmoset as another small, non-human primate species in which the pathogenesis of GBV-B can be studied and used as a surrogate model of HCV infection for investigation of pathogenesis and antiviral drug development.

Six New World primates, including 2 golden lion tamarins (Leontopithecus rosalia), 2 cotton-top tamarins (Saguinus o. oedipus), 1 black howler monkey (Alouatta caraya), and 1 black-handed spider monkey (Ateles g. geoffroyi), were diagnosed with unilateral (4/6) or bilateral (1/6) adrenal or extra-adrenal (1/6) pheochromocytoma by light microscopy and immunohistochemical staining for chromogranin A. Overt invasive behavior or metastases were not observed in any primate, and thus these neoplasms were considered benign. All primates either died spontaneously (4/6) or were euthanatized (2/6) as a result of concurrent malignant neoplasia, infection, renal disease, or a combination of several disease processes. Although we did not determine whether these pheochromocytomas were functional, all 6 primates had myocardial fibrosis, and some had arteriosclerosis.

Abstract In humans and macaque monkeys, socially relevant face processing is accomplished via a distributed functional network that includes specialized patches in frontal cortex. It is unclear whether a similar network exists in New World primates, who diverged ~35 million years from Old World primates. The common marmoset is a New World primate species ideally placed to address this question given their complex social repertoire. Here, we demonstrate the existence of a putative high-level face processing network in marmosets. Like Old World primates, marmosets show differential activation in anterior cingulate and lateral prefrontal cortices while they view socially relevant videos of marmoset faces. We corroborate the locations of these frontal regions by demonstrating functional and structural connectivity between these regions and temporal lobe face patches. Given the evolutionary separation between macaques and marmosets, our results suggest this frontal network specialized for social face processing predates the separation between Platyrrhini and Catarrhini.

AbstractThe New World species of Pseudonapomyza Hendel are reviewed. Only two species of the genus were previously known to occur in the Nearctic region: P. atra (Meigen) and P. lacteipennis (Malloch). Pseudonapomyza europaea Spencer and P. asiatica Spencer are here recorded for the first time in the Nearctic region and P. asiatica is recorded for the first time in Costa Rica and Venezuela. A key is provided to identify the four known New World species of Pseudonapomyza.

AbstractOmiodes Guenée is redescribed based on all New World species, including the type species O. humeralis Guenée. Four new species from Costa Rica, O. janzeni sp. n., O. hallwachsae sp. n., O. sirena sp. n., O. ochracea sp. n., are described. Ten new synonymies are established : Phostria disciiridescens Hampson is =O. croeceiceps (Walker), Phostria cayennalis Schaus is =O. grandis (Druce), Omiodes ochrosoma Felder & Rogenhofer and Phryganodes gazalis Schaus are =O. pandaralis (Walker), Nacoleia lenticurvalis Hampson, Phryganodes anchoritalis Dyar, and Phostria duplicata Kaye are =O. confusalis (Dognin), O. cervinalis Amsel is =O. martvralis (Lederer), Nacoleia indicata ab. pigralis Dognin and Botis fortificalis Möschler are =O. metricalis (Möschler). One new combination is recognized: O. pandaralis (Walker) was transferred from Coelorhynchidia Hampson. A key and an updated checklist to the neotropical Omiodes species is provided, including O. indicata (Fabricius), a worldwide pest. Ten species that do not belong in Omiodes are retained until appropriate generic placements are identified.
