The Role Of Mechanical Injury In An Experimental Transmission Of Flexibacter Columnaris To Fingerling Walleye, Manzoor Hussain, Robert C. Summerfelt
Journal of the Iowa Academy of Science: JIAS
The role of mechanical injury in transmission of Flexibacter columnaris to walleye fingerlings (Stizostedion vitreum vitreum) was investigated. Two groups (1 and 2) of 10 fish each, 7 to 9 cm total length, were exposed to a suspension of F lexibacter columnaris containing 3 X 105 cfu/ mL; fish in group 1 were injured with a scratch along their flank; fish in group 2 were not injured. Two control groups (3 and 4) of 5 fish each were exposed to a sterile broth; group 3 was injured with a scratch and group 4 was not. In 72 h, morbidity was …
