Bacterial microbiota in harbor seals (Phoca Vitulina) from the North Sea of Schleswig-Holstein, Germany, around the time of mornillivirus and Influenza epidemics
We present microbiologic findings in harbor seal (phoca; Phoca vitulina) carcasses collected from the North Sea of Schleswig-Holstein, Germany, 1996–2014, and interpret results in relation to potential variations caused by phocine distemper virus and influenza A virus mass mortalities. We conducted...
