Abstract Comparisons of mammalian gut microbiota across different environmental conditions shed light on the diversity and composition of gut bacteriome and suggest consequences for human and animal health. Gut bacteriome comparisons across different environments diverge in their results, showing no generalizable patterns linking habitat and dietary degradation with bacterial diversity. The challenge in drawing general conclusions from such studies lies in the broad terms describing diverse habitats (“wild”, “captive”, “pristine”). We conducted 16S ribosomal RNA gene sequencing to characterize intestinal microbiota of free-ranging sympatric chimpanzees and gorillas in southeastern Cameroon and sympatric chimpanzees and gorillas in a European zoo. We conducted participant-observation and semi-structured interviews among people living near these great apes to understand better their feeding habits and habitats. Unexpectedly, bacterial diversity (ASV, Faith PD and Shannon) was higher among zoo gorillas than among those in the Cameroonian forest, but zoo and Cameroonian chimpanzees showed no difference. Phylogeny was a strong driver of species-specific microbial composition. Surprisingly, zoo gorilla microbiota more closely resembled that of zoo chimpanzees than of Cameroonian gorillas. Zoo living conditions and dietary similarities may explain these results. We encourage multidisciplinary approach integrating environmental sampling and anthropological evaluation to characterize better diverse environmental conditions of such investigations.

Hydatidosis/cystic echinococcosis (CE) caused by Echinococcus granulosus is a parasitic zoonotic disease worldwide, threatening animal health and production and public health safety. However, it is still unclear that whether E. granulosus infection can result in the alteration of gut microbiota in Tibetan sheep. Therefore, a study was designed to investigate the influences of E. granulosus infection on gut microbiota of Tibetan sheep. A total of 10 ovine small intestinal contents (five from healthy and five from infected) were obtained and subjected to high-throughput sequencing by MiSeq platform. A total of 2,395,641 sequences and 585 operational taxonomic units (OTUs) were identified. Firmicutes and Proteobacteria were the most dominant phyla in all samples. Moreover, the proportions of Armatimonadetes and Firmicutes in the infected Tibetan sheep were significantly decreased, whereas Actinobacteria, Chloroflexi, and Acidobacteria had significantly increased. At the genus level, the Christensenellaceae_R-7_group and Ruminococcaceae_NK4A214_group were the predominant bacterial genera in all the samples. Furthermore, the healthy Tibetan sheep exhibited higher abundances of Intestinimonas, Butyrivibrio, Pseudobutyrivibrio, Ruminococcaceae, Eubacterium_coprostanoligenes_group, Oxobacter, Prevotella_1, Ruminiclostridium_6, Coprococcus_1, Ruminococcus, Lachnospiraceae_UCG-002, Olsenella, and Acetitomaculum, whereas Kocuria, Clostridium_sensu_stricto_1, Slackia, Achromobacter, and Stenotrophomonas levels were lower. In conclusion, our results conveyed an information that E. granulosus infection may cause an increase in pathogenic bacteria and a decrease in beneficial bacteria. Additionally, a significant dynamical change in gut microbiota could be associated with E. granulosus infection.

Multidrug resistance (MDR) is already occurring among some equids in India. Donkeys and mules are a mobile species moving between regions and international borders, often populating areas of India where private community pharmacies, or medical stores, are the primary healthcare provider for both humans and animals. This article highlights how the capacities of drug retail outlet workers might affect their antibiotic dispensing practices, particularly in relation to donkeys and mules, in order to consider how this might impact the development of antimicrobial resistance (AMR) on a wider scale. A mixed-methods approach was implemented using patient simulation method (n = 28), semi-structured interviews (SSIs) (n = 23), focus group discussions (FGDs) with veterinary practitioners and non-governmental organisation animal health workers (n = 2 FGDs), and participant observation. Fewer than 48 per cent of drug retail outlet workers admitted to having had any formal training in pharmaceuticals at all, while 78 per cent reported having no formal training in animal-related pharmaceuticals. Moreover, 35 per cent of all participants sold antibiotics without a prescription, unprompted and without specifically being asked for antibiotics. Of the antibiotics dispensed, only 21 per cent were correctly dispensed for the symptoms presented, and all dosages dispensed were incorrect (underdosed). Furthermore, 43 per cent of drug retail outlet workers interviewed believe that some antibiotics can be legally dispensed without a prescription. Equine owners in northern India are frequently being sold antibiotics without a prescription and, in most cases, with incorrect diagnoses, treatment choice, and dosage. A substantial gap in capacities exists amongst Drug Retail Outlet (DRO) workers, with few being sufficiently qualified or trained to dispense antibiotics to animal owners. The study highlights the need for further training of private DRO workers as well as knowledge extension and awareness training for both DRO workers and animal owners regarding antimicrobial resistance and its potential impact upon livelihoods. It also illustrates the need to identify a balance whereby greater enforcement of regulation at all levels is implemented, while at the same time maintaining sufficient access to medicine for rural populations.

AbstractThe gut microbiome plays a key role in animal health and metabolism through the intricate functional interconnection between the feed, gut microbes, and the host. Unfortunately, in aquaculture, the links between gut microbes and fish genetics and production phenotypes are not well understood.In this study, we investigate the associations between gut microbial communities, fish feed conversion, and fish genetics in the domestic Atlantic salmon. Microbial community composition was determined for 230 juvenile fish from 23 full-sib families and was then regressed on growth, carbon and nitrogen metabolism, and feed efficiency. We only found weak associations between host genetics and microbial composition. However, we did identify significant (p < 0.05) associations between the abundance of three microbial operational taxonomical units (OTUs) and fish metabolism phenotypes. Two OTUs were associated with both carbon metabolism in adipose tissue and feed efficiency, while a third OTU was associated with weight gain.In conclusion, this study demonstrates an intriguing association between host lipid metabolism and the gut microbiota composition in Atlantic salmon.

This work is the result of the doctoral thesis entitled Pilgrimage of Bom Jesus da Lapa: Social Reproduction of the Family and Female Gender Identity, specifically the second chapter that talks about women in the Pilgrimage of Bom Jesus da Lapa, emphasizing gender relations, analyzing the location of the pilgrimage as a social reproduction of the patriarchal family and female gender identity. The research scenario is the Bom Jesus da Lapa Pilgrimage, which has been held for 329 years, in that city, located in the West part of Bahia. The research participants are pilgrim women who are in the age group between 50 and 70 years old and have participated, for more than five consecutive years in the Bom Jesus da Lapa Pilgrimage, belonging to five Brazilian states (Bahia, Minas Gerais, São Paulo, Espírito Santo and Goiás) that register a higher frequency of attendance at this religious event. We used bibliographic, qualitative, field and documentary research and data collection as our methodology; we applied participant observation and semi-structured interviews as a technique. We concluded that the Bom Jesus da Lapa Pilgrimage is a location for family social reproduction and the female gender identity, observing a contrast in the resignification of the role and in the profile of the pilgrim women from Bom Jesus da Lapa, alternating between permanence and the transformation of gender identity coming from patriarchy.

Sports Tourism as a segment is growing exponentially in Brazil. The sports mega-events that occurred in the period from 2007 to 2016 helped strengthen this sector significantly. This article examined tourism mobility during the Summer Olympic Games Rio 2016, hosted by the city of Rio de Janeiro, Brazil. This study expands the understanding of the relationship between tourism and city infrastructure, therefore being relevant to academics, professionals of the area and to the whole society due to its multidisciplinary field. The existence of a relationship between means of transportation and the Olympic regions as well as tourist attractions for a possible legacy was observed. Data were collected from official sources, field research and through participant-observation and semi structured interviews. Data were coded and analyzed. The results indicate that the city was overall successful in its execution of sufficient mobility. New means of transportation were added and others updated. BRT's (Bus Rapid Transit) were the main use of mass transport to Olympic sites. However, a lack of public transport access was observed for the touristic sites.

Abstract A variety of microorganisms inhabit the gastrointestinal tract of animals including bacteria, archaea, fungi, protozoa, and viruses. Pioneers in gut microbiology have stressed the critical importance of diet:microbe interactions and how these interactions may contribute to health status. As scientists have overcome the limitations of culture-based microbiology, the importance of these interactions has become more clear even to the extent that the gut microbiota has emerged as an important immunologic and metabolic organ. Recent advances in metagenomics and metabolomics have helped scientists to demonstrate that interactions among the diet, the gut microbiota, and the host to have profound effects on animal health and disease. However, although scientists have now accumulated a great deal of data with respect to what organisms comprise the gastrointestinal landscape, there is a need to look more closely at causative effects of the microbiome. The objective of this review is intended to provide: 1) a review of what is currently known with respect to the dynamics of microbial colonization of the porcine gastrointestinal tract; 2) a review of the impact of nutrient:microbe effects on growth and health; 3) examples of the therapeutic potential of prebiotics, probiotics, and synbiotics; and 4) a discussion about what the future holds with respect to microbiome research opportunities and challenges. Taken together, by considering what is currently known in the four aforementioned areas, our overarching goal is to set the stage for narrowing the path towards discovering how the porcine gut microbiota (individually and collectively) may affect specific host phenotypes.

We characterized the gut microbial composition and relative abundance of gut bacteria in the larvae and adults of Pieris canidia by 16S rRNA gene sequencing. The gut microbiota structure was similar across the life stages and sexes. The comparative functional analysis on P. canidia bacterial communities with PICRUSt showed the enrichment of several pathways including those for energy metabolism, immune system, digestive system, xenobiotics biodegradation, transport, cell growth and death. The parameters often used as a proxy of insect fitness (development time, pupation rate, emergence rate, adult survival rate and weight of 5th instars larvae) showed a significant difference between treatment group and untreated group and point to potential fitness advantages with the gut microbiomes in P. canidia. These data provide an overall view of the bacterial community across the life stages and sexes in P. canidia.

AbstractMicrobiome is known to play an important role in the health of organisms and different factors such as diet have been associated with modifications in microbial communities. Differences in the microbiota composition of wild and captive animals has been evaluated; however, variation during a reintroduction process in primates has never been reported. Our aim was to identify changes in the bacterial composition of three individuals of reintroduced woolly monkeys (Lagothrix lagothricha) and the variables associated with such changes. Fecal samples were collected and the V4 region of the 16S rRNA gene was sequenced to determine gut microbial composition and functionality. Individual samples from released individuals showed a higher microbial diversity after being released compared to before liberation, associated with changes in their diet. Beta diversity and functionality analysis showed separation of samples from released and captive conditions and the major factor of variation was the moment of liberation. This study shows that intestinal microbiota varies depending on site conditions and is mainly associated with diet diversity. The intake of food from wild origin by released primates may promote a positive effect on gut microbiota, improving health, and potentially increasing success in reintroduction processes.
