How do the different species of Eimeria differ?
All of the coccidia are pathogenic, although some, like Eimeria praecox and E. mitis, to a lesser degree. The life cycle of each Eimeria species has a different duration inside the host and as a consequence a different prepatent period. This represents a valuable diagnostic tool in identifying the species ofEimeria, together with the location and appearance of lesions, which are very specific to each different species.
How does coccidiosis impact on bird performance?
Coccidiosis causes death and in less severe cases causes intermittent diarrhoea, poor growth rates, poor feed conversion and variation in body weight.
However, we have to make a distinction: for the broiler industry, it is subclinical coccidiosis that has more impact, by undermining the efficiency of feed digestion. In contrast, the biggest concern in the breeder industry is clinical coccidiosis, which causes the death of the bird and promotes opportunistic pathologies associated with intestinal damage or birds’ stress.
The most commonly recognised species in broiler chickens are Eimeria acervulina, E. tenella and E. maxima. Eimeria praecox and Eimeria mitis are common but are recognised as responsible for subclinical coccidiosis.
In layer and breeder pullets, apart from Eimeria acervulina, E. tenella and E. maxima, we also have to consider E. necatrix and E. brunetti, which impact late in the production cycle but produce severe damage to the gut and mortality.
