“…In addition, pesticides, especially glyphosate, inhibit several of the bacterial microbiome taxa distinctive for bats from natural forests (Campylobacteraceae, Streptococcaceae, and Neisseriaceae) (Shehata et al, 2013;Mao et al, 2018;Blot et al, 2019). It reduces microbiome diversity and taxonomic richness of Bacteroidetes and Proteobacteria phyla (Yang et al, 2019), causes inflamed gut microenvironments, and induces blooms of Enterobacteriaceae in mice (Stecher et al, 2012). Generally, glyphosate decreases commensal bacterial species, but not pathogenic ones (Shehata et al, 2013), supporting our hypothesis that microbial communities from monocultures may be dysbiotic.…”

Habitat alteration for agriculture can negatively affect wildlife physiology and health by decreasing diet diversity and increasing exposure to agrochemicals for animals foraging in altered landscapes. Such negative effects may be mediated by the disruption of the gut microbiota (termed dysbiosis), yet evidence for associations between habitat alteration, wildlife health, and the gut microbiota remains scarce. We examine the association between management intensity of banana plantations and both the body condition and gut microbiota composition of nectar-feeding bats Glossophaga soricina, which commonly forage within banana plantations across Latin America. We captured and measured 196 bats across conventional monocultures, organic plantations, and natural forests in Costa Rica, and quantified gut microbiome bacterial phylogenetic diversity using 16S rRNA amplicon sequencing. We found that gut microbiota from bats foraging in conventional monocultures were overall less phylogenetically diverse than those from bats foraging in organic plantations or natural forests, both of which were characterized by diverse bacterial assemblages and individualized microbiota. Despite lower diversity, co-occurrence network complexity was higher in conventional monocultures, potentially indicating altered microbial interactions in agricultural landscapes. Bats from both organic and conventional plantations tended to be larger and heavier than their forest counterparts, reflecting the higher food supply. Overall, our study reveals that whilst both conventional monocultures and organic plantations provide a reliable food source for bats, conventional monocultures are associated with less diverse and potentially dysbiotic microbiota, whilst organic plantations promote diverse and individualized gut microbiota akin to their natural forest-foraging counterparts. Whilst the long-term negative effects of anthropogenically-altered microbiota are unclear, our study provides further evidence from a novel perspective that organic agricultural practices are beneficial for wildlife health.

“…The GM of the rats was affected by GLY exposure, alone or in a formulation; an accumulation of shikimic acid and a raised level of metabolites were found in cecum but not in serum, suggesting an effect restricted only on the gut microbiota [ 41 ]. The action of the glyphosate-based herbicide (Roundup) on the immune system and gut microbiota of crab ‘ Eriocheir sinensis ’ led to a reduction in digestive enzyme activities and in an assortment of microbiota, but amplified the abundance of Bacteroidetes and Proteobacteria at the taxonomic level [ 42 ]. In vitro, bacterial growth cultured from marine turtles’ guts exposed to GLY was strongly repressed.…”

In recent years, new targets have been included between the health outcomes induced by pesticide exposure. The gastrointestinal tract is a key physical and biological barrier and it represents a primary site of exposure to toxic agents. Recently, the intestinal microbiota has emerged as a notable factor regulating pesticides’ toxicity. However, the specific mechanisms related to this interaction are not well known. In this review, we discuss the influence of pesticide exposure on the gut microbiota, discussing the factors influencing gut microbial diversity, and we summarize the updated literature. In conclusion, more studies are needed to clarify the host–microbial relationship concerning pesticide exposure and to define new prevention interventions, such as the identification of biomarkers of mucosal barrier function.

“…In other species (Chinese mitten crab), the antioxidant ability of the intestine decreased with the effect of the pesticide and the content of malondialdehyde increased. As a result of sequencing, an analysis was performed that showed that glyphosate reduced the diversity of the intestinal microbiota of the Chinese mitten crab, and the taxonomic richness of bacteroids and proteobacteria increased significantly [58]. Glyphosate, absorbed with food, directly contacted with the intestinal microbiota of pollinating insects.…”

In recent decades an increase in the use of pesticides to protect plants from pests, diseases and weeds has been observed. There are many studies on the effects of various pesticides on non-target organisms. This review aims to analyze and summarize published scientific data on the effects of pesticides on the animal microbiome. Pesticides can affect various parameters of the animal microbiome, such as the taxonomic composition of bacteria, bacterial biodiversity, and bacterial ratios and modify the microbiome of various organisms from insects to mammals. Pesticide induced changes in the microbiome reducing the animal’s immunity. The negative effects of pesticides could pose a global problem for pollinators. Another possible negative effect of pesticides is the impact of pesticides on the intestinal microbiota of bumblebees and bees that increase the body’s sensitivity to pathogenic microflora, which leads to the death of insects. In addition, pesticides can affect vitality, mating success and characteristics of offspring. The review considers methods for correcting of bee microbiome.
