Isolation and Identification of Micro- Flora Streptococci from Chicken Intestine and the Effects of Antibiotic and Heavy Metals on Growth

In present study we isolated Streptococcus bovis from the chicken intestine ( duodenum, ileum, rectum) and fecal materials. The results founded all isolates can grow on nutrient agar, resistance to antibiotics Nitrofurantion (300 g), ChloramphenicoI 30g) Norfloxacin (10g), Ampicillin (10g) and diameter of inhibition (15mm) in Amikacin (10g) compared to diameter of inhibition (mm) in control of Amikacin 17mm and, exhibited the highest MIC to certain heavy metals, MIC=14mM for pb+2 and MIC=18 mM for Cd+2
