Clostridial enteritisis a common cause of diarrhoea in pet avian species and is the most frequentlycultured enteric pathogens. Clostridia are anaerobic, spore forming bacteriathat are ubiquitous and can survive in soil and faeces for many years (Hess etal., 1998; Dorrestein, 1997; Garner et al., 2000). Psittacine birds lack caecumor have only vestigial remnants.
Clostridium sp. found in gastrointestinaltract of psittacine birds are aberrant and are generally considered eitherpathogens or transitory passengers (Wilson et al., 1999). Pathogenic bacterial strainsof this genus can be acquired in birds from ingestion, wound contamination, orovergrowth of normal gastrointestinal flora (Filippich and Domrow, 1985). Thisreport describes the diagnostic and therapeutic modalities used in clostridialenteritis in red lories (Eos bornea),rainbow lorikeet (Trichoglossusmoluccanus) and green naped lorikeet (Trichoglossushematodus hematodus) maintained at commercial parrot farm in Injambakkam, Chennai,Tamil Nadu during 2016. Materialsand methods A total of 110psittacine birds (50 lories, 30 rainbow lorikeet and 30 green naped lorikeets)were housed in cages in Injambakkam, Chennai, Tamil Nadu, India wasinvestigated.
The birds were fed with the mixture of fresh fruits, boiledvegetables, sprouted seeds and oats after fine grinding to make a uniform semisolidto liquid consistency with honey. Out of 110 birds, 50 red lories (Eos bornea) bought from a trader wereintroduced in to the farm without any quarantine procedures. Out of 110 birds, 10 birds were died withoutany clinical signs. Postmortem and histopathological examination of dead birdswas carried out to find out the causation of death. Samples of ingesta from thenecropsied birds, cloacal swabs from live birds were collected and stained bygram staining as per the standard protocol. Swab and ingesta was cultured usingstandard bacterial isolation technique.
