“…Changes in predator-prey dynamics and disruptions in the trophic structure are unavoidable and expected consequences of changes to biodiversity [77]. Geographic ranges, prolonged exposure to prey during feeding, co-species roosting, and social behavior have numerous implications for disease transmission [78].…”

The growing population in Yucatan has led to the expansion of construction in the Mayan jungle for tourist spaces, residential areas, and agriculture. Recently, rabies cases in cats (Felis catus) have increased. This study aimed to perform the antigenic and genetic characterization of the RABV and to try to identify factors contributing to the increased transmission of rabies virus from wildlife to cats in the State of Yucatan. The ArcGIS software was employed to generate maps depicting the geographic locations of rabies outbreaks in cats. A mixed-effects Poisson regression model was applied to investigate the association between cat rabies cases and sociodemographic and ecological variables. A total of nine feline rabies cases occurred, three antigenic variants were detected: RVV1 (n=1); (RVV3) (n=1), and the canine-originated atypical variant (n=7). Rabies cases were spatially distributed at the urban-jungle interface, which may favor contact between cats and wildlife. No statistically significant associations with sociodemographic/ecological variables were observed. Urban areas with low (0-2%) to moderate (2-4%) changes in land cover showed a substantial increase in the probability of feline rabies cases. This study highlights the concerning resurgence of rabies infections in cats, emphasizing the looming threat of its reintroduction in dogs should vaccination rates diminish. The genetic affinity between the atypical variant and the canine virus underscores the urgent need for vigilance in maintaining high vaccination coverage across all susceptible species.

“…In turn, hematophagous bats may have a life expectancy of around 7 to 12 years in the wild. As blood is a high-quality food source, hematophagous bats require less energy to obtain their nutrients than insectivorous bats, for example, which need to consume large quantities of insects to meet their dietary needs [37]. Additionally, hematophagous bats have evolved specialized adaptations, such as powerful jaw muscles and sharp teeth, which allow them to feed on blood more efficiently [38].…”

The aim of this study was to compare the oxidative metabolism of four neotropical bat species with different feeding habits and investigate the relationship between their feeding habits and oxidative status. In terms of oxidative damage, our findings revealed major differences among the four bat species. In particular, hematophagous bats had lower levels of oxidative damage in the heart but higher levels in the liver. Nectarivorous bats had lower levels of carbonyl groups in the kidneys compared to insectivorous and hematophagous bats. The activity of various antioxidant and non-antioxidant enzymes in the heart, liver, and kidney also showed significant differences among the bat species. H2O2 consumption was lower in the heart of hematophagous bats, while insectivorous bats exhibited the highest enzymatic activity in the kidney. SOD activity was lower in the heart of hematophagous bats and lower in nectarivorous bats in the liver. Fumarase activity was higher in the heart of frugivorous/insectivorous and lower in nectarivorous/hematophagous bats. GPx activity was higher in the heart of nectarivorous/insectivorous and higher in the kidney of insectivorous bats. GST activity was higher in the heart of nectarivorous and lower in hematophagous bats. The correlation analysis between oxidative markers and enzymatic/non-enzymatic antioxidants in the heart, liver, and kidney exhibited distinct patterns of correlations due to variations in antioxidant defense mechanisms and oxidative stress responses in different organs. The observed differences in oxidative damage, antioxidant enzyme activities, and correlations between oxidative markers and antioxidants highlight the adaptability and complexity of the antioxidant defense systems in these bats. Each organ appears to have specific demands and adaptations to cope with oxidative stress based on its physiological functions and exposure to dietary components. Our results have major significance for the conservation and management of bats, which are threatened species despite being crucial components of ecosystems. Our study’s implications go beyond bat biology and offer valuable insights into comparative oxidative physiology.

“…In spite of recent policies to discourage their use, antibiotics are still widely used in the livestock industry in America [12]. One of the most important interactions of livestock with wildlife throughout America is that established with the common vampire bat (Desmodus rotundus; [13,14]). The common vampire bat feeds on blood of several mammal species and it acts as a micropredator of livestock [15].…”

Antibiotics are pharmaceutical products that have the potential to affect the immune performance of wildlife. Wildlife species might incorporate antibiotic residues in their system by feeding on livestock treated with these chemicals. One of the most important interactions of livestock with wildlife is that established with the common vampire bat (Desmodus rotundus). We used vampire bats as an ecologically relevant model to test the effect of antibiotics on wildlife immune response. We tested the effect of clindamycin on the humoral and cellular acquired immune responses of common vampire bats captured in the wild in southern Mexico. We expected that both cellular and humoral acquired immune responses would be negatively affected after bats were exposed to clindamycin for several days. We measured local inflammation and serum immunoglobulin concentration (IgG) after the repeated application of phytohemagglutinin. We expected that antibiotic-exposed bats would present a weaker inflammatory response to a second injection of PHA and that their IgG serum levels did not increase to the same rate after the third PHA injection. Antibiotic-treated vampire bats exhibited weaker inflammatory response to the repeated PHA treatment: induced swelling was ~30% larger after the second injection than that after the first injection, whereas swelling after the second injection in antibiotic-treated bats was ~10% lower than after the first injection. There was an increase of IgG serum levels following three consecutive PHA injections but it occurred only in vampires that did not receive the antibiotic: IgG serum levels of control individuals increased ~90% over pre-injection values, whereas this value was ~15% lower in vampires treated with antibiotic. Our study adds to previous evidence pointing to the negative effect that exposure to anthropogenic chemicals generates in wildlife capacity to maintain a healthy immune system and warrants further work on the relationship of potential antibiotic-induced changes in gut microbiota and immune response.
