| |
| − | *Disease frequently seen in lambs under 6 months old
| |
| − | **More often in twins and triplets when single lambs
| |
| − |
| |
| − | *Oocyts from ewes (immune carriers) accumulate in poorly managed litter or around feed and water troughs
| |
| − |
| |
| − | *Lambs born early in the year amplify the parasite problem increasing the parasite risk to lambs born later in the year
| |
| − |
| |
| − | *Affected lambs may die before oocysts are found in the faeces
| |
| − | **Post-mortem diagnosis difficult
| |
| − |
| |
| − | *Different species of ''Eimeria'' occurs in sheep and goats
| |
| − |
| |
| − | *Infection may be coincident with ''Neospora'' or ''Cryptosporidium'' infections
| |
| − | **Mixed infections complicate the diagnosis as oocyst differentiation is difficult
| |
| − |
| |
| − | *Other non-pathogenic species can cause papillomatous mucosal growths

| − | *Preventative measures include creep feeding lambs with decoquinate or oral dosing with diclazuril when lambs are 4-6 weeks
| |
| − | **A second dose can be given after 3 weeks
