                  | This  question was fairly attempted by the candidates.  In 5(a-b), most of the candidates were able  to define the term parasite and mention the signs that could be noticed in a  sick goat.  However, most of the  candidates were unable to discuss the anthrax disease under causative organisms  and modes of transmission but most of them were able to discuss the disease  under animals affected and symptoms as required in 5c(i-iii) and 5(c)(ii-iv)  respectively.  More so, majority of them  could not draw and label the reproductive tract of a hen as required in 5(d). The  expected answers include:
 (c)      Discussion  on anthrax disease
 (i)         Causative  organism
 -           Bacillus anthracis
 
 (iii)       Modes of transmission
 -         Ingestion  of contaminated feeds
 -         Inhalation  of spores
 -         Drinking of contaminated water
 -         Open  wounds/body contact
 -         Contaminated  soil
 -         Contaminated  equipment e.g. feeder, drinker etc.
 -          Vector/flies/rats/birds etc.
 (d)
