“…Psychrobacter is the dominant genus in the skin microbiota of captive bottlenose dolphins and killer whales (Chiarello, Villeger, Bouvier, Auguet, & Bouvier, 2017). It acts as an opportunistic pathogen in the skin lesions of pinnipeds (Alvarez‐Perez et al, 2010). The Dorea genus was highly abundant in the gut microbiota of adult P. largha .…”

Age is an important factor that significantly impacts the gut microbiota of various mammals. Captive spotted seals (Phoca largha) provide an ideal opportunity to study how age affects their gut microbiota, excluding other environmental factors, which is a challenge when monitoring wildlife. Here, the bacterial composition of the feces of captive spotted seals from four age groups were analyzed; namely, pup (<1 year old), juvenile (1-2 years old), subadult (2-3 years old), and adult (≥4 years old). Firmicutes were the dominant bacteria in all measured feces; however, the composition of gut microbiota in seals of different ages was distinct. Blautia, Slackia, and an unclassified Peptostreptococcaceae were more abundant in pups; Clostridium was abundant in juveniles; Fusobacterium, Bacteroides, and Psychrobacter were abundant in subadults; and Dorea and Peptostreptococcus abundant in adults. Two and 4 years of age appeared to be the most influential time nodes for variation in gut microbiota. In conclusion, this study identified age-related differences in the composition of gut microbiota in P. largha.

Marine animals surfaces host diverse microbial communities, which play major roles for host’s health. Most inventories of marine animal surface microbiota have focused on corals and fishes, while cetaceans remain overlooked. The few studies focused on wild cetaceans, making difficult to distinguish intrinsic inter- and/or intraspecific variability in skin microbiota from environmental effects. We used high-throughput sequencing to assess the skin microbiota from 4 body zones of 8 bottlenose dolphins (Tursiops truncatus) and killer whales (Orcinus orca), housed in captivity (Marineland park, France). Overall, cetacean skin microbiota is more diverse than planktonic communities and is dominated by different phylogenetic lineages and functions. In addition, the two cetacean species host different skin microbiotas. Within each species, variability was higher between individuals than between body parts, suggesting a high individuality of cetacean skin microbiota. Overall, the skin microbiota of the assessed cetaceans related more to the humpback whale and fishes’ than to microbiotas of terrestrial mammals.

“…The treatment with ketoconazole was successful and led to negative results of control cultures [ 40 ]. Also there is the clinical report announcing the mycosis caused by R. mucilaginosa in female sea lion [ 20 ]. The probable source of infection could have been the water contaminated by Rhodotorula yeasts, which have been found in seawater [ 15 ] Additionally, in captive or zoo animals, the important factors predisposing to mycosis are various stresses connected with captivity.…”

Mixed Infection of Respiratory Tract in a Dog Caused by Rhodotorula mucilaginosa and Trichosporon jirovecii: A Case Report

et al. 2017

This report describes the isolation of two environmental fungi: Rhodotorula mucilaginosa and Trichosporon jirovecii accompanied by Pseudomonas aeruginosa and Escherichia coli from a dog with bronchotracheitis. All microorganisms were isolated routinely from a mucopurulent discharge, obtained during bronchoscopy from laryngotracheal area. The initial identification of yeasts was confirmed by API Candida and by molecular analysis of internal transcribed spacer region. Administered antimicrobial treatment with Marbofloxacin and Canizol has brought the improvement in the dogs’ health status. The final results of control mycological culture were negative. Most probably underlying hypothyroidism and the use of steroids were the factors predisposing this patient to opportunistic infection of mixed aetiology. As far as we are concerned, this is the first case of dogs’ respiratory tract infection caused by R. mucilaginosa and T. jirovecii.
