Abstract
Bacteria play an essential role in the health of marine mammals, and the bacteria of marine mammals are widely concerned, but less is known about freshwater mammals. In this study, we investigated the bacteria of various body sites of Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) and analyzed their association with freshwater environmental bacteria. The bacterial community and function of Yangtze finless porpoise showed apparent site-specificity. Various body sites have distinct differences in bacteria and have their dominant bacteria. Romboutsia, Plesiomonas, Actinobacillus, Candidatus Arthromitus dominated in the intestine (fecal and rectal samples). Fusobacterium, Streptococcus, and Acinetobacter dominated in the oral. The dominant genera in the blowhole include Suttonella, Psychrobacter, and two uncultured genera. Psychrobacter, Flavobacterium, and Acinetobacter were dominant in the skin. The alpha diversity of intestinal (fecal and rectal) bacteria was the lowest, while that of skin was the highest. The oral and skin bacteria of Yangtze finless porpoise significantly differed between the natural and semi-natural conditions, but no sex difference was observed. A clear boundary was found between the animal and the freshwater environmental bacteria. Even the skin bacteria, which are more affected by the environment, are significantly different from the environmental bacteria and harbor indigenous bacteria. Our results provide a comprehensive preliminary exploration of the bacteria of Yangtze finless porpoise and its association with bacteria in the freshwater environment.

Leitzen E, Peters M, Merbach S, Wohlsein P, Baumgärtner W. Suttonella ornithocola detected within lesions of tit birds (Paridae) from epidemic death episodes in Germany, 2018–2020. Front Vet Sci 2022; 9:977570. [PMID: 36157175 PMCID: PMC9493112 DOI: 10.3389/fvets.2022.977570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 08/22/2022] [Indexed: 11/13/2022] Open
Abstract
Several episodes of increased mortality in wild birds of the families Paridae and Aegithalidae have been documented in recent decades. The majority of affected animals exhibited necrotizing pneumonia with intralesional bacteria. Suttonella (S.) ornithocola, a gram-negative bacterium in the Cardiobacteriaceae family, has been regularly cultured bacteriologically from affected birds and has long been suspected as a potentially fatal cause of respiratory disease in birds. However, a direct causal relationship between this specific bacterium and the observed lesions within birds has not yet been established. Therefore, postmortem tissue from six tits was used in the present study, including three blue tits (Cyanistes caeruleus) and three great tits (Parus major). Five of the six tits tested positive for S. ornithocola in bacteriological examination and originated from two incidents of increased mortality in Paridae in Germany. Animals found dead in the administrative district of Arnsberg (North Rhine Westphalia) in 2018 and 2020 were investigated for genomic fragments of S. ornithocola by chromogenic in situ hybridization using a newly developed DNA probe based on publicly assessable DNA sequences of the 16S rRNA gene of S. ornithocola. Positive hybridization signals were detected in five out of five animals and were predominantly detected within necrotizing lesions in lung and occasionally in lesions affecting liver and trachea. Interestingly, the lung of one animal without obvious necrotizing pulmonary lesions revealed positive hybridization results in the lumen of one pulmonary blood vessel. Two negative controls, including one bacteriologically S. ornithocola-negative great tit and a cattle egret (Bubulcus ibis) suffering from salmonellosis, did not yield positive signals, indicating high sensitivity and specificity of the probe used. This is the first time that S. ornithocola has been clearly identified within necrotizing lesions in deceased tits. Although Koch's postulates have yet to be fulfilled, positive hybridization signals in association with detectable lesions are considered as further and strong evidence of the significant contribution of S. ornithocola to the several episodes of tit mortality recorded in Germany.

Abstract
Diplotriaena obtusa is a nematode found in air sacs of a wide number of birds, including Passerine species. During a period of increased mortality of blue tits (Cyanistes caeruleus) in Germany, we collected adult nematode worms from the air sacs of a deceased male blue tit. The nematodes showed morphological features consistent with Diplotriaena ssp. A polymerase chain reaction (PCR) assay targeting the small subunit (SSU) 18S rRNA gene identified the parasite species as Diplotriaena obtusa. Phylogenetic analysis confirmed species identification. Further examinations against infectious pathogens like Suttonella ornithocola, Salmonella spp., Pasteurella spp., Chlamydia spp., Influenza A virus, Usutu virus and West Nile virus were negative. This is the first report of D. obtusa in a blue tit from Germany.
