Clostridium perfringens Toxin Types in Hooded Seals in the Greenland Sea, Determined by PCR and ELISA
Very little is known about the occurrence of Clostridium perfringens and of diseases caused by this anaerobic bacterium in marine mammals, especially those that are free‐living. During a scientific expedition to the Greenland Sea (West Ice) in spring 1999, faeces samples from 70 hooded seals ( Cysto...
