Also, two or more players can each have a baton and throw a ball to the other player in something similar to badminton or racket-ball or even handball or volleyball.

Abstract: The present invention is related to a DNA sequence of outer membrane proteins of Actinobacillus pleuropneumoniae expressed in a subject suffering from pleuropneumonia, the sequence coding for the receptor for the uptake of ferric hydroxamate FhuA as set forth in SEQ ID NO: 1 in Actinobacillus pleuropneumoniae, or any functional fragment thereof. The present invention also relates to a DNA sequence of outer membrane proteins of Actinobacillus pleuropneumoniae expressed in a subject suffering from pleuropneumonia, the sequence coding for a hemoglobin-binding protein as set forth in SEQ ID NO: 4 in Actinobacillus pleuropneumoniae, or any functional fragment thereof. The present invention further relates to composition, diagnostic kit and methods using the DNA sequences of the present invention.
