Overview
Cooperia spp. are largely considered mild pathogens however there are a few species that are of greater veterinary importance, namely; C. punctata and C. pectinata. These species are pariste of cattle and small ruminants and most species of this genus prefer warmer climates.
Identification
Cooperia worms have a distinctive red colouration and a coiled appearance. The adults are between 5-8mm in length and males can be recognised by the presence of a dipropotionately large bursa at the anterior end. The worms have 16 gut cells and a square ended anterior in the females, containing refractile bodies. The tail end of the Cooperia species has one of two forms dependant on the species, in those like C. oncophora the tail tapers to a point where as in those resmbling C. curticei the sheath tip is finely pointed and contains refractile bodies. Eggs can usually be identified under microsscopic examination due to the almost parallel walls of the egg.
