A not so proud peacock...
A young backyard peacock was noted to have drooping feathers and not roosting in the coop at night. A fecal flotation was performed and revealed the following organisms (400X total magnification).
In this flotation, numerous coccidian oocysts*, a capillarid egg+, and a tapeworm egg^ (possibly Raillietina sp. or Hymenolepis sp. based on morphology) are present. Signs of coccidiosis in birds include decreased growth rate, and may include severe diarrhea that is often bloody; death from coccidiosis is also not uncommon. Infection with capillarids may cause nonspecific signs such as general unthriftiness, inactivity, anorexia, and decreased growth; however, severe inflammation and thickening of the crop, esophagus, or small intestine in heavy infections can lead to death. Depending on the species of cestode and the number of worms present, tapeworm infections in birds can range from non-pathogenic to severely pathogenic and fatal.
