Technical Abstract: During experimental Eimeria infection in chickens, facilities are contaminated by fecal oocysts which are known to be highly resistance to both chemical and enzymatic treatments. Thus, studies on experimental Eimeria infection have been limited by requirement of complete elimination of residual oocysts in cages and facilities. To overcome this limitation, a simple, inexpensive and disposable cage was made of a cardboard box and monitored experimentally to Eimeria infection. The cage has been used in animal rooms without evidence of cross-contamination with coccidia between adjacent cages. No significant differences in fecal oocyst output and body weight gain were noted between in disposable cage and in wire cage used as a control. The cage proved to be a useful means of preventing contamination of oocysts in experimental tools, indicating that the disposable cage can be used for other infectious diseases in avians.
