Hassan Ali T, Hayyawi, SM., Effect of lactic acid bacteria on antibiotic resistant Pseudomonas aeruginosa, Onl J Vet Res., 23 (7):733-741, 2019. Authors describe effect of lactic acid bacteria (LAB) on growth of Pseudomonas aeruginosa In Vitro. We tested 154 milk samples for pseudomonas aeruginosa from cows with mastitis and isolated LAB from milk samples from 50 healthy cows. Isolation and identification of bacteria was done by culture media, gram stain and biochemical tests and susceptibility of Pseudomonas aeruginosa growth on Mueller Hinton agar. We found 6/154 samples positive for P. aeruginosa with resistance to Azithromycin (80.3%); Ciprofloxacin (62.6%); Aztreonam and Ceftazidime (31.3%), Netilmicin, Gentamycin, Oxytetrocyclin and Meropenem (17.6%), and no resistance to Imipenem, Piperacilin, Tobramycin, and Amikacin. We isolated Lactobacillus casei and Bifidobacterium spp for inhibitory test against our P aeruginosa finding resistance to be ~14% (MIC 11-14 mm).
