“…Subsistence hunting is the only known route for the establishment of the domestic cycle of E. vogeli (Meneghelli et al 1992, D'Alessandro et al 2008, Almeida et al 2013. This occurs through contact with the domestic dogs that accompany the hunts and are often fed raw game meat, which may sometimes be infected with E. vogeli (Siqueira et al 2013, Bittencourt-Oliveira et al 2018.…”

“…Palavras-chave: equinococose neotropical; caça de subsistência; Amazônia brasileira; armadilha fotográfica. The subsistence hunting of wild mammals is common and widespread in the rural and indigenous communities of the Amazon region (Peres & Palacios 2007), which paca and agouti are important game species to rural communities in central-western portion of Brazilian Amazon (Sampaio et al 2022) and dogs are widely used for hunting (Bittencourt-Oliveira et al 2018, Guimarães et al 2019. Humans are considered to be an accidental intermediate host of E. vogeli (Rausch & Bernstein 1972) -they are infected through the accidental ingestion of eggs present in the feces of domestic dogs (Eckert & Thompson 2017).…”

The helminth Echinococcus vogeliRausch & Bernstein, 1972 is a causative agent of Neotropical Echinococcosis, a chronic zoonotic disease which is endemic to the Neotropical region. This parasite is transmitted from bush dogs (Speothos venaticus) to their prey, which include lowland pacas (Cuniculus paca) and agoutis (Dasyprocta spp.). In Brazil, most human cases of Neotropical Echinococcosis have been recorded in the Amazonian states of Acre and Pará, although few data are available on the occurrence of the potential definitive or intermediate hosts of E. vogeli in the Amazon region. In the present study, we surveyed the forests surrounding 46 human communities located within and around of outside six sustainable-use protected areas in the southwestern Amazon basin of Brazil. The forests were surveyed using camera traps to determine the local presence of potential wild hosts of E. vogeli, and the exploitation of these hosts for game meat was evaluated through interviews with 136 subsistence hunters resident in the local communities. We recorded pacas, agoutis, and bush dogs, as well as domestic dogs (Canis familiaris), all potential reservoirs of Neotropical Echinococcosis, using the same habitats. We also confirmed the frequent consumption of paca and agouti meat by subsistence hunters and their families in the study communities. Our data contribute to the understanding of the occurrence of E. vogeli in Brazilian ecosystems.

The larvae of Echinococcus (hydatidcyst) can parasitize humans and animals, causing a serious zoonotic disease-echinococcosis. The life history of Echinococcus is complicated, and as the disease progresses slowly after infection, early diagnosis is difficult to establish. Due to the limitations of imaging and immunological diagnosis in this respect, domestic and foreign scholars have established a variety of molecular detection techniques for the pathogen Echinococcus over recent years, mainly including nested polymerase chain reaction (PCR), multiplex PCR, real-time quantitative PCR, and nucleic acid isothermal amplification technology. In this article, the research progress of molecular detection technology for Echinococcus infection currently was reviewed and the significance of these methods in the detection and diagnosis of hydatid and hydatid diseases was also discussed.

“…Unfortunately, relatively little research has been conducted on zoonotic disease transmission from wild meat in the Neotropics (Mayor et al, 2017). The paucity of data is alarming given that Amazonia has been characterized as a hotspot for the emergence of zoonotic disease (Han et al, 2016) and that a variety of zoonotic pathogens have been identified among important Amazonian subsistence species including Echinococcus in paca ( Cuniculus paca ) (Bittencourt‐Oliveira et al, 2018; Mayor et al, 2015), Trypanosoma cruzi and Yellow Fever virus in nonhuman primates (Fernandes et al, 2017; Marcili et al, 2009; Muniz et al, 2013), and Leptospirosis in peccaries ( Tayassu tajacu ) (Mendoza et al, 2007).…”

The consumption of primates is integral to the traditional subsistence strategies of many Indigenous communities throughout Amazonia. Understanding the overall health of primates harvested for food in the region is critical to Indigenous food security and thus, these communities are highly invested in long‐term primate population health. Here, we describe the establishment of a surveillance comanagement program among the Waiwai, an Indigenous community in the Konashen Amerindian Protected Area (KAPA). To assess primate health in the KAPA, hunters performed field necropsies on primates harvested for food and tissues collected from these individuals were analyzed using histopathology. From 2015 to 2019, hunters conducted 127 necropsies across seven species of primates. Of this sample, 82 primates (between 2015 and 2017) were submitted for histopathological screening. Our histopathology data revealed that KAPA primates had little evidence of underlying disease. Of the tissue abnormalities observed, the majority were either due to diet (e.g., hepatocellular pigment), degenerative changes resulting from aging (e.g., interstitial nephritis, myocyte lipofusion), or nonspecific responses to antigenic stimulation (renal and splenic lymphoid hyperplasia). In our sample, 7.32% of individuals had abnormalities that were consistent with a viral etiology, including myocarditis and hepatitis. Internal parasites were observed in 53.66% of individuals and is consistent with what would be expected from a free‐ranging primate population. This study represents the importance of baseline data for long‐term monitoring of primate populations hunted for food. More broadly, this research begins to close a critical gap in zoonotic disease risk related to primate harvesting in Amazonia, while also demonstrating the benefits of partnering with Indigenous hunters and leveraging hunting practices in disease surveillance and primate population health assessment.
