New duck disease caused by Riemerella anatipestifer is a new disease emerged in Kerala from 2008 onwards. Six R. anatipestifer isolates responsible for the disease were isolated from suspected ducks from different outbreak areas of the state and were identifi ed. Since the ecological, morphological and cultural characteristics of R. anatipestifer are more or less similar to Pasteurella multocida, the disease is often confused with duck pasteurellosis and misdiagnosed. R. anatipestifer infection is also characterized by the presence of bipolar organisms in blood smear and impression smears of organs as in the case of P. multocida, but the size is little larger. The detection and identifi cation of the causative bacterium, from ducks with signs and lesions consistent with the acute or chronic form of the disease, is one of the most important aspects of disease diagnosis. Hence, a study was conducted to isolate the agent of new duck disease and stating its differential biotyping characters from that of P. multocida. They were differentiated using tests like indole production, gelatin liquefaction, ornithine decarboxylases utilization and fermentation of glucose. The antibiogram pattern was determined to advocate the choice of drug for the purpose of treatment. All the R. anatipestifer isolates were sensitive to chloramphenicol, ciprofl oxacin, enrofl oxacin, norfl oxacin, gentamicin, clindamycin, doxycycline and cefuroxime.

“…3). Several workers reported the high sensitivity of R. anatipestifer to penicillin G, erythromycin and polymyxin B (Baba et al,1987;Pathanasophon et al, 1991 andPathanasophon et al, 1994). Chang et al,(2003) conducted in vitro and in vivo antibiogram using ceftiofur and 16 commonly used antibiotics against 50 isolates of R. anatipestifer .…”

The outbreak of Riemerella anatipestifer (RA) infection has been confirmed in meat-type domestic ducks (Anas platyrhynchos) for the first time in 27 years in Japan. In January 2014, increased mortality in a 14- to 21-day-old duck flock was reported to veterinary officials by the owner. The affected ducks exhibited reduced movement, ataxia and dorsal recumbency with leg paddling. Pathological findings were typical for an RA infection. Fibrinous and heterophilic pericarditis, airsacculitis, perihepatitis, ventriculitis and meningitis were observed. The bacterial isolate from duck organs was identified as RA by PCR-based 16S ribosomal RNA sequencing.
