“…We found seven important genera that can best discriminate the gut microbial profiles of 0 ~ 1.5-months-old cubs, 1.5 ~ 6-month-old cubs, 6 ~ 9-month-old cubs and adults: Shewanella, Helicobacter, Oblitimonas, Haemophilus, Aeromonas, Listeria , and Fusobacterium . Many species of Shewanella have been reported to reduce metals and toxins (Harris et al, 2017); the other six genera Helicobacter (Fischbach and Malfertheiner, 2018), Oblitimonas (Drobish et al, 2016), Haemophilus (Bakaletz and Novotny, 2018), Aeromonas (Cardoso et al, 2018), Listeria (Salama et al, 2018), and Fusobacterium (Guven and Dizdar, 2018) have been implicated in human diseases. Helicobacter was even expressed in higher abundance in 6 ~ 9-month-old cubs than in adults, suggesting that giant panda would be more susceptible to digestive diseases in this stage.…”

Adult giant pandas (Ailuropoda melanoleuca) express transitional characteristics in that they consume bamboos, despite their carnivore-like digestive tracts. Their genome contains no cellulolytic enzymes; therefore, understanding the development of the giant panda gut microbiome, especially in early life, is important for decoding the rules underlying gut microbial formation, inheritance and dietary transitions. With deep metagenomic sequencing, we investigated the gut microbiomes of two newborn giant panda brothers and their parents living in Macao, China, from 2016 to 2017. Both giant panda cubs exhibited progressive increases in gut microbial richness during growth, particularly from the 6th month after birth. Enterobacteriaceae dominated the gut microbial compositions in both adult giant pandas and cubs. A total of 583 co-abundance genes (CAGs) and about 79 metagenomic species (MGS) from bacteria or viruses displayed significant changes with age. Seven genera (Shewanella, Oblitimonas, Helicobacter, Haemophilus, Aeromonas, Listeria, and Fusobacterium) showed great importance with respect to gut microbial structural determination in the nursing stage of giant panda cubs. Furthermore, 10 orthologous gene functions and 44 pathways showed significant changes with age. Of the significant pathways, 16 from Escherichia, Klebsiella, Propionibacterium, Lactobacillus, and Lactococcus displayed marked differences between parents and their cubs at birth, while 29 pathways from Escherichia, Campylobacter and Lactobacillus exhibited significant increase in cubs from 6 to 9 months of age. In addition, oxidoreductases, transferases, and hydrolases dominated the significantly changed gut microbial enzymes during the growth of giant panda cubs, while few of them were involved in cellulose degradation. The findings indicated diet-stimulated gut microbiome transitions and the important role of Enterobacteriaceae in the guts of giant panda in early life.

“…Several years ago, V. cholerae were identified from cloacal swabs and feces taken from different species of aquatic birds [ 6 , 7 ]. In a recent study, several Vibrio species, including V. cholerae, were recovered from debilitated wrecked marine birds in Brazil [ 8 ]. Pretzer et al (2017) [ 9 ] reported the occurrence of highly diverse V. cholerae non-O1, non-O139 populations in an Austrian lake (Neusiedler See) and migrating birds were hypothesized to play a key role in the transfer of the strains over long distances.…”

Phenotypic and Genotypic Properties of Vibrio cholerae non-O1, non-O139 Isolates Recovered from Domestic Ducks in Germany

et al. 2020

Vibrio cholerae non-O1, non-O139 bacteria are natural inhabitants of aquatic ecosystems and have been sporadically associated with human infections. They mostly lack the two major virulence factors of toxigenic V. cholerae serogroups O1 and O139 strains, which are the causative agent of cholera. Non-O1, non-O139 strains are found in water bodies, sediments, and in association with other aquatic organisms. Occurrence of these bacteria in fecal specimens of waterfowl were reported, and migratory birds likely contribute to the long-distance transfer of strains. We investigated four V. cholerae non-O1, non-O139 isolates for phenotypic traits and by whole genome sequencing (WGS). The isolates were recovered from organs of domestic ducks with serious disease symptoms. WGS data revealed only a distant genetic relationship between all isolates. The isolates harbored a number of virulence factors found in most V. cholerae strains. Specific virulence factors of non-O1, non-O139 strains, such as the type III secretion system (TTSS) or cholix toxin, were observed. An interesting observation is that all isolates possess multifunctional autoprocessing repeats-in-toxin toxins (MARTX) closely related to the MARTX of toxigenic El Tor O1 strains. Different primary sequences of the abundant OmpU proteins could indicate a significant role of this virulence factor. Phenotypic characteristics such as hemolysis and antimicrobial resistance (AMR) were studied. Three isolates showed susceptibility to a number of tested antimicrobials, and one strain possessed AMR genes located in an integron. Knowledge of the environmental occurrence of V. cholerae non-O1, non-O139 in Germany is limited. The source of the infection of the ducks is currently unknown. In the context of the ‘One Health’ concept, it is desirable to study the ecology of V. cholerae non-O1, non-O139, as it cannot be excluded that the isolates possess zoonotic potential and could cause infections in humans.

“…cholerae non-O1/non-O139 was isolated from cloacal swab samples of wild manx shearwater ( Puffinus puffinus ) that were caught in the north-central coast of Rio de Janeiro, Brazil [70]. In another survey that was conducted in the same place a few years later, Cardoso and colleagues [71] isolated and identified V . cholerae non-O1/non-O139 isolates from waterbird species: kelp gull ( Larus dominicanus ), Atlantic yellow-nosed albatross ( Thalassarche chlororhynchos ), brown booby ( Sula leucogaster ), Cabot’s tern ( Thalasseus acuflavidus ), and grey-headed gull ( Chroicocephalus cirrocephalus ) (Table 1, S1 Table).…”

“…They found that waterbirds showed the highest minimal inhibitory concentration (MIC) values to all studied antimicrobial agents (except ampicillin) compared with strains isolated from fish or chironomids [73]. Cardoso and colleagues [71] isolated V . cholerae resistant to ampicillin from the brown booby ( Sula leucogaster ).…”

Accumulating evidence suggests that some waterbird species are potential vectors of Vibrio cholerae

Vibrio cholerae is the causative agent of cholera, a life-threatening diarrheal disease. Cholera causes epidemics and pandemics, but the ways this disease spreads worldwide is still unclear. This review highlights a relatively new hypothesis regarding the way V . cholerae can be globally dispersed. Copepods and chironomids are natural reservoirs of V . cholerae and are part of different fish species’ diet. Furthermore, V . cholerae inhabits marine and freshwater fish species. Waterbird species feed on fish or on small invertebrates such as copepods and chironomids. Waterbirds have also been found to carry living copepods and/or chironomids internally or externally from one waterbody to another. All of the above points to the fact that some waterbird species might be vectors of V . cholerae . Indeed, we and others have found evidence for the presence of V . cholerae non-O1 as well as O1 in waterbird cloacal swabs, feces, and intestine samples. Moreover, hand-reared cormorants that were fed on tilapia, a fish that naturally carries V . cholerae , became infected with this bacterial species, demonstrating that V . cholerae can be transferred to cormorants from their fish prey. Great cormorants as well as other waterbird species can cover distances of up to 1,000 km/day and thus may potentially transfer V . cholerae in a short time across and between continents. We hope this review will inspire further studies regarding the understanding of the waterbirds' role in the global dissemination of V . cholerae .
