DEVELOPMENTAL INTESTINAL AEROBIC MICROFLORA IN THE KORI BUSTARD (ARDEOTIS-KORI)

A study was carried out to investigate the normal aerobic bacterial fl ora of developing kori bustard (Ardeotis kori) chicks, captive bred at the National Avian Research Center, Abu Dhabi, United Arab Emirates, Faecal samples were collected from 14 birds at different ages from the first day of hatching until 99 days old and were cultured for aerobic bacteria. Several bacterial species were isolated from the cultures, they included Escherichia coli, Streptococcus viridians, Enterococcus faecalis, Klebsiella oxytoca, Proteus spp,, Enterobacter, spp, and Ser ratia marcescens. Gram-negative bacilli were isolated from all but one of the faecal samples collected. They were also the predominant bacte ria, accounting for between 55.6 and 73.4% of the mean colony count of faecal cultures from all age groups. E. coli was the most frequently isolated bacteria, the frequency and mean colony count increased as th e birds grew older. Gram-positive cocci were isolated from between 50 and 100% of the faecal samples from all age groups, and they accounted for between 26.6 and 44.4% of the mean colony count. Results from thi s study indicated that Gram-negative bacilli and Gram-positive cocci c an be isolated frequently from the faeces of developing, clinically no rmal, captive bred kori bustard chicks.
