title: Systemic dexamethasone and its effect on normal aerobic bacterial flora of cow.
abstract: This study was carried out on 17 Holestein, heifers, aged between 1 to 2 years for determining the normal aerobic bacterial flora and their changes after dexamethasone injection. Swab samples were taken from eye, ear, pharynx and vagina before and 5 days after twice dexamethasone treatment. Results indicated that Bacillus cereus and Corynebacterium pseudotuberculosis had higher frequency of isolations than the other bacterial flora in eye, ear and pharynx. Actinomyces pyogenes was isolated with considerable frequency from vagina. Klebsiella pneumoniae was also isolated from pharynx and its frequency was increased significantly after dexamethasone injection (p < 0.05).
