Online published on 4 May, 2019. Abstract Clostridial enteritis was reported in a commercial parrot farm of about 600 adult birds. Overall mortality due to clostridial enteritis was 9.09 percent in lories and lorikeet. Out of which 12 percent in lories (Eos bornea), 6.6 percent in rainbow lorikeet (Trichoglossus moluccanus) and 6.6 percent in green naped lorikeet (Trichoglossus hematodus hematodus) was recorded. On post-mortem examination, all birds showed severe necrosis and ulceration of the intestines. On histopathological examination, liver revealed diffuse congestion, vacuolar degeneration and focal necrosis and infiltration of inflammatory cells. Intestinal mucosa revealed diffuse necrosis, sloughing of epithelium, stunning and fusion of villi. Grams staining revealed gram positive organisms with sub-terminal and terminal spores. Anaerobic culture of ingesta revealed Clostridium perfringens. Birds were treated with Metronidazole @ 25 mg/kg b. wt. during first outbreak and Clindamycin @100mg/kg b. wt. during second outbreak. From this study, it was concluded that recent purchase of few birds and its introduction in the aviary, environmental and hygienic problems played a major role in development of clostridial enteritis.
