Abstract
The studies were conducted on the prevalence, immunization and therapeutic control of
Eimeria species infections in fowls. The results obtained have been discussed earlier in
detail, the same have been summarized as follows:
1. A total of 2100 faecal samples and 1490 intestinal samples from birds were
examined during the present investigation and 1216 faecal samples (57.095%)
and 687 intestinal scrapings (46.107%) were found positive for the Eimeria
species infections.
2. The per cent prevalence of E. tenella (34.24 %), E. necatrix (10.34 %), E.
acervulina (0.62%) and mixed infection with E. tenella + E. necatrix (4.91%), E.
tenella + E. acervulina (3.09%), E. necatrix +E. acervulina (2.47%) and E.
tenella + E. necatrix + E. acervulina (2.34%) were recorded.
3. The fowls of 0-3 months age were found highly susceptible to the different
Eimeria species of infections on the basis of faecal sample and intestinal
scraping examination.
4. The maximum prevalence of Eimeria spp. infection was recorded during
monsoon season followed by winter and summer on the basis of faecal sample
and intestinal scraping examination.
5. The haemato-biochemical observations showed decrease in haemoglobin and
PCV values in infected untreated birds throughout the experimental studies.
6. TLC (%) values were also found increased in infected untreated birds
throughout the experimental observations.
7. Lymphocytes (%) significantly found increased in during infection.
8. The marked monocyte (%) population was noted reduced and eosinophils (%)
were seen to get increased in the infected untreated birds.
9. Whereas the basophiles (%) were found unchanged in all groups on different
days of observations.
10. The neutrophils (%) significantly decreased in infected untreated birds.
11. The total serum protein (g/dL) was found decreased in infected untreated birds.
12. The AST (I.U/dL), ALT (I.U/dL) and the serum glucose (mg/dl) were noted to be
significantly increased in infected untreated birds.
13. The x-ray irradiated 32(mAs) group and 12th passaged oocysts inoculated fowls
had higher body weight gain. While the infected birds showed reduced body
weight gain.
14. The oocyst Per Gram (OPG) was observed to be more in infected untreated
birds while the lowest OPG count was observed in 32(mAs) x-ray irradiated
oocysts inoculated birds.
15. The cent percent efficacy of neem leaf water extract and Amprolium
hydrochloride treated were observed in infected treated birds.
16. The severe lesion score (++++) was observed in infected untreated fowls.
17. The high stimulation index (S.I) value was observed on 31th day in passaged
oocysts inoculated fowls.
18. A distinct band of precipitation was observed in Agar Gel Precipitation Test in
12th Passaged birds.
