“…Contamination with Salmonella often implies fecal contamination (Uzzau et al, 2000), be it direct or indirect. Consumption of contaminated poultry products has frequently been associated with foodborne salmonellosis, mainly owing to the ingestion of raw or undercooked eggs or meat (Carter, Adams, Woodward, & La Ragione, 2009;Revolledo et al, 2006) although swine and their products have been implicated as well (Foley et al, 2008). Effective control is difficult due to the numerous potential sources of Salmonella infection and product contamination in integrated poultry enterprises (Poppe, 2000;Revolledo et al, 2006).…”

“…Meanwhile, in case of food animals, the occurrence of enteric disease can lead to huge economic loss. Salmonellosis is a highly contagious food borne pathogen with important economic repercussions in commercial poultry [5,6]. The use of antibiotics can be an effective way to control these types of infections, however, the use of antibiotic in food animals and the concern over the spread of antibiotic resistance genes is gaining global attention.…”

“…The enteric complications in humans, impending ban of antibiotics in animal feed, the failure to identify new antibiotics and the inherent problems with developing new vaccines make a compelling case for developing alternative prophylactics. One such alternative approach involves the use of probiotics or beneficial bacterial cultures [6,8,9].…”

Over a century ago Eli Metchnikoff proposed the revolutionary idea to consume viable bacteria to promote health by modulating the intestinal microflora. The idea is more applicable now than ever, since bacterial antimicrobial resistance has become a serious worldwide problem both in medical and agricultural fields. The interest in digestive physiology and the microbiome has generated data whereby well being of all living organisms with a digestive tract can be enhanced and the risk of disease reduced. Given the recent international legislation and domestic consumer pressures to withdraw growth-promoting antibiotics and limit antibiotics available for treatment of bacterial infections, probiotics can offer alternative options. Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Current indications are that mechanism of action involves a number of possibilities like rapid activation of innate host immune responses, assisting in the digestion of food materials etc. In this review, we focused on applying probiotic concept to alleviate chronic constipation and idiopathic diarrhea in humans or for specific pathogen reduction and improvement of GIT diseases in poultry.

“…The inhibitory activity of LAB against CP has been previously reported and is mainly attributed to the accumulation of primary metabolites such as lactic acid, ethanol, and carbon dioxide and production of other antimicrobial compounds such as bacteriocins [16,29,[38][39][40]. The production levels and proportions among these compounds depend on the biochemical properties of the strains used, and physical and chemical conditions of growth [41][42][43].…”

Necrotic Enteritis (NE) caused by Clostridium perfringens (CP) in poultry is probably the most important bacterial disease in terms of economic implications. The disease is multi-factorial and is invariably associated with predisposing factors. The present study investigated the effect of a commercially available Lactobacillus-based probiotic (FM-B11) for the control of necrotic enteritis in broiler chickens. In experiment 1, one-day-of-hatch broiler chicks were randomly allocated to the following treatment groups: 1) Non-challenged (NC); 2) Challenged (C); 3) Challenged + probiotic (C+ FM-B11). Prior to placement, chicks in groups 2 and 3 received 0.25 mL of Salmonella typhimurium (ST) containing 10 5 cfu of viable cells by oral gavage. At 14, 15 and 16 days of age, all chicks in group 3 were treated with FM-B11 in the drinking water at a concentration of 10 6 cfu/ml. At 21d of age, all chicks in groups 2 and 3, were individually challenged with 5 × 10 4 sporulated oocysts of E. maxima by oral gavage. At 26d of age, all chicks in groups 2 and 3, were individually challenged with 10 8 cfu CP; body weight (BW) was recorded prior to challenge. The experiment was terminated at 29 days of age and the following parameters were evaluated: NE-associated mortality, CP lesion scores, CP concentrations in ileum, BW, and body weight gain (BWG). Chicks treated with FM-B11 had significantly (P < 0.05) higher body weight gain after challenge when compared to control challenge chickens. Total mortality was higher in the C group (48.8%) when compared to the C + FM-B11 (12.7%). Even though there was no significant (P > 0.05) difference in lesion score between C and C + FM-B11, group C + FM-B11 had significantly (P < 0.05) lower total number of cfu of CP recovered from the ileal mucosa and content samples when compared to group C. Experiment 2 was a unique and remarkable case report of a field outbreak of NE in a commercial broiler farm in Argentina. A reduction and control of the mortality associated with NE following 3 days of administration of FM-B11 was observed as compared with the control non treated house. These results imply that the commercially available Lactobacillus-based probiotic FM-B11 was able to reduce the severities of NE, as a secondary bacterial infection, in an experimental NE challenge model; as well as, in a commercial field outbreak of NE.
