Coccidiosis of sheep in sout part of Serbia
Apstrakt
Coccidian protozoa of the genus Eimeria are common in sheep around the world. Coccidia have a very
complicated life cycle, with many stages of development. The egg-like structure of coccidia is called an
oocyte. It is passed in the feces of infected sheep and goats. When first passed, the oocyst is not infective.
It must undergo a period of development called sporulation (hatching). Sporulation requires oxygen and
moisture. When a sheep ingests a sporulated oocyst, sporozoites are released and enter the cells lining
the small intestines..Lambs between the ages of 1 and 6 months are most commonly affected by coccidia.
During our examination, 4 to 8 week old lambs were the most likely to be affected and 4 week old lambs
were the most vulnerable to clinical disease. Many disease outbreaks occur shortly after weaning, as this
is a very stressful period in the lamb young life. Typical signs include diarrhea, dysentery, dehydration
and loss of appetite and body condition. Sheep can ...usually tolerate small burdens of coccidia, but if
parasite numbers become large, for example as a result of an environment heavily contaminated with
viable infective oocysts, or other stressors affecting the sheep, disease can result. During our
examination performed in period 2017-2019 in sheep herds in south part of Serbia cocidiosis were
occured at 37.92%. We usally occured mixed infection with 3-4 coccidia species. At sheep most
abundant species were E. ovina found at 76.7%, followed by E.ovinoidalis (63%), E faurei(42%),
E.ahsata (37%), E. granulosa (28%), E. intricata (15%), and E. pallida (3%). Oocyst were found at
adult ant young animals, but clinical sign of disease were present only at young animals. The number of
excreted oocysts was higher in lambs (26625+/-23993 OPG) than in adult sheep (19974+/-11353 OPG).
