The Effectiveness of Amoxicillin and Cefalexin in Two Species from Staphylococcus and Bacillus Isolated from Bovine Mastitis in Sudan

Abstract

In this study 60 milk samples collected from mastitic cows to isolates and identify bacterial agents. The percentage of isolates was as follows: Staphylococcus spp 52%, Bacillus spp 26%, Enteroccocispp 3%; microccus 3%, Nesseria 2%, Branhamella 3%, Clostridium 1%, Bordetella 2%, Enterobacteria 3%, Aeromonas 4%, Fusobacterium 1%. In sensitivity tests used two antibiotics Amoxicillin and Cephalexin against two highest isolates in this study (Staph spp and Bacillus spp and found: Staph. aureus and Staph. hyicus were resistant to Amoxicllin and cephlaxin relatively, Bacillus coagulans and Bacillus cereus were susceptible to Amoxicllin and cephlaxin.
