Poultry Coccidiosis: Design and Interpretation of Vaccine Studies

Coccidiosis in Poultry: An Overview

Introduction Coccidiosis is one of the most important diseases of poultry caused by protozoa, Eimeria and is generally characterized by bloody diarrhea, the primary symptom and high mortality. The bloody diarrhea is mainly due to intestinal epithelium dying off since a large number of oocysts and merozoites burst out of the cells. The disease spreads from one bird to another by contact with inf...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Genetic association studies: Design, analysis and interpretation

This paper provides a review of the design and analysis of genetic association studies. In case control studies, the different contingency tables and their relationships to the underlying genetic model are defined. Population stratification is discussed, with suggested methods to identify and correct for the effect. The transmission disequilibrium test is provided as an alternative family-based...
