Use of anaerobic cecal microflora, lactose and acetic acid for the protection of broiler chicks against experimental infection with Salmonella Typhimurium and Salmonella enteritidis BJM
Andreatti Filho,Raphael Lucio; Silva,Edir Nepomuceno da; Ribeiro,Aldemir Reginato; Kondo,Nancy; Curi,Paulo Roberto.
The effects of treatment with anaerobic cecal microflora (ACM) and/or lactose and/or acetic acid on systemic and digestive tract of broiler chicks infection with Salmonella Typhimurium and S. Enteritidis were studied. ACM was used without previous bacterial identification. Treatment with ACM contributed to the resistance of broiler chicks to infection with Salmonella spp. The infections were more persistent in the cecum, rectum and crops in decreasing order of intensity. The infections were also self-limiting since treated and control lots presented similar infection rates at the end of the experiments. Alone or in combination with lactose, ACM reduced the colonization of the digestive tract of broiler chicks by S. Typhimurium and S. Enteritidis. The...

Identification and adhesion profile of Lactobacillus spp. strains isolated from poultry BJM
Rocha,Ticiana Silva; Baptista,Ana Angelita Sampaio; Donato,Tais Cremasco; Milbradt,Elisane Lenita; Okamoto,Adriano Sakai; Andreatti Filho,Raphael Lucio.
In the aviculture industry, the use of Lactobacillus spp. as a probiotic has been shown to be frequent and satisfactory, both in improving bird production indexes and in protecting intestine against colonization by pathogenic bacteria. Adhesion is an important characteristic in selecting Lactobacillus probiotic strains since it impedes its immediate elimination to enable its beneficial action in the host. This study aimed to isolate, identify and characterize the in vitro and in vivo adhesion of Lactobacillus strains isolated from birds. The Lactobacillus spp. was identified by PCR and sequencing and the strains and its adhesion evaluated in vitro via BMM cell matrix and in vivo by inoculation in one-day-old birds. Duodenum, jejunum, ileum and cecum were...
