Article Synopsis
- Animals, particularly birds, use cosmetic substances like uropygial secretions in sexual selection and communication, which may involve pigments produced by symbiotic bacteria.
- The study focuses on the spotless starling nestlings, revealing that the yellow secretion they use to stain their mouths is influenced by the microbiota present, particularly under varying oxidative conditions.
- Results indicate that antioxidant supplementation enhances the complexity and diversity of the microbial community in the secretion, suggesting a connection between bacteria and the coloration of these cosmetic traits.
The consumption of raw or smoked fish entails significant microbiological risks, including contamination by pathogens such as , which can cause severe foodborne illnesses. This study explores the preservative use of piscicolin CM22, a novel bacteriocin derived from the psychrotolerant strain CM22, in two types of edible coatings (EC): chitosan-based and fish gelatin-based. An initial in vitro characterization of the technological and antimicrobial properties of these ECs with and without bacteriocin was conducted.

However, their increasing price and low sustainability have led the aquafeed industry to seek sustainable alternative feedstuffs to meet the nutritional requirements of fish and improve their health and performance. Plant proteins have been successfully used to replace fishery derivatives in aquafeeds, but the presence of anti-nutritional substances is a potential drawback of this approach.

- Animal bacterial symbionts are established early in life through vertical and horizontal transmission, influenced by both physical and social environments, posing challenges in understanding social effects on bacterial communities in wild animals.
- In a study involving Eurasian magpies and great spotted cuckoos, it was found that magpies raised in heterospecific nests had more diverse and richer bacterial communities compared to those in monospecific nests.
- The research highlights how social interactions significantly impact the development of bacterial communities on bird skin, particularly during the nestling period, demonstrating the importance of these interactions in a brood parasite-host relationship.
Article Synopsis
- Bacteria in avian nests may affect nest odors, influencing how parasites detect their hosts through olfactory cues.
- A study on 10 bird species revealed that the diversity of bacteria and their volatile compounds correlated with the intensity of ectoparasitism and nestling success.
- Findings suggest that the microbial environment plays a significant role in both ectoparasite pressures and fledging outcomes, warranting further experimental research into these interactions.
