First record of <i>Philometra ovata</i> (Nematoda) infection in <i>Gobio lozanoi</i> in Portugal

Abstract

Gobio lozanoi , from the River Febros northern Portugal, contained female Philometra ovata in the body cavity causing abdominal swelling. A mild chronic inflammation and some tissue necrosis were observed in infected fish. Significant correlations were found between occurrence of infection and host length, and gonado‐somatic index; and between intensity of infection and condition factor.
