QUESTION
Diagnosis of coccidiosis in chicken is best accomplished by?
OPTIONS
(A) Clinical signs
(B) Post mortem examination
(C) Oocyst count
(D) Demonstration of Oocyst in droppings
ANSWER
(B) Post mortem examination
EXPLANATION
Postmortem examination is particularly useful for diagnosing poultry coccidiosis because lesion location and appearance in different intestinal segments can indicate the Eimeria species and severity, and mucosal scrapings can confirm developmental stages. Clinical signs and fecal oocysts alone are less specific because oocyst shedding may not correlate well with disease severity.
