Antibacterial activity of lactobacillus species isolated from dairy products against antibiotics

Lactobacillus have a remarkable record of safety and have been consumed by humans for decades. In the present study, different milk products were collected and inoculated for identifying isolation of lactobacillus sp in MRS plate. Colonies grown was subjected for gram staining and other cultural characteristics. Then antimicrobial assay of Lactobacillus species was performed by agar well diffusion method in Mueller Hinton Agar (MHA) plates. Samples was inoculated in the Cultured plates of lactobacillus using different antibiotics such as Sufasalazine, Metronidazole, Ciprofloxacin and Ampicillin. It is proved that usage of high dosage of antibiotics will have the chance of damaging the normal flora.
