“…However, the comparison of interference of probiotics strains at colonization of E. coli O157 and non-O157 between animals young and older is little studied. Usually the studies are made in cattle than sheep (Nielsen et al, 2002 ) or focusing just the reducing of shedding (Zhao et al, 1998;Lema et al, 2001;Kritas et al, 2006;Maragkoudakis et al, 2010). Strategies using probiotics strains into ruminant´s compartment to reduce the shedding of pathogenic microorganisms on the farm reducing thus the occurrence of diseases have been efficient according to some authors (ChaucheyrasDurant et al, 2010;Lema et al, 2001;Guarner and Malagelada, 2003).…”

“…STEC bacteria are food-borne pathogens that may cause human diseases such as diarrhea, hemorrhagic colitis (HC) and, in some cases, hemolytic uremic syndrome (HUS) (World Health Organization, 1998). Some studies have reported the rumen compartment as being a relevant target for intervention strategies to reduce the number of viable STEC cells; one such intervention strategy may be the use of probiotics supplemented in rations (Lema et al, 2001;Zhao et al, 1998;Rattray et al, 2007;Whitley et al, 2009;Chaucheyras-Durant et al, 2010;Maragkoudakis et al, 2010).…”

Domestic ruminants, especially sheep and cattle, are the main reservoirs of Shiga toxin-producingEscherichia coli (STEC) and may transmit this pathogen to human. Probiotics are "live organisms that, when administered in adequate amounts, confer a health benefit on the host", decreasing the infection and its dissemination. However, these benefits are conferred only after the colonization of probiotic strains in the gut of the animal, which may be impaired by normal microbiota. The aims of this study were to determine whether the inoculation of sheep with probiotic strains decreases the shedding of STEC and to determine whether the age of sheep interferes with this protective effect. Sheep that received oral inoculums at a concentration of 2 × 10 9 cells per mL of viable STEC bacteria, which are carriers of stx1, stx2 and eae genes, were compared with other sheep that did not receive inoculums. When probiotic bacteria were inoculated together with the STEC, the number of pathogenic bacteria in the population was similar to the control. The protective effect of probiotic strains was largest in groups with younger animals than with older animals. These findings suggest that the use of probiotic strains in sheep may decrease the intestinal shedding by STEC as well as the fact that the age of the sheep may interfere in the protective effect of probiotics against colonization by STEC.

“…For example, a host Lactobacillus strain reduces STEC shedding in beef cattle, but does not affect performance [41], while a host Lactobacillus strain reduced pig performance after an E. coli F4 challenge which resulted in greater E. coli F4 shedding [42]. Adding to this confusion, non-host probiotics and prebiotics increase milk production [43], alleviate disease [3,4] and decrease pathogen shedding [44], but the responses are quite variable. In an effort to determine why products differ in their effectiveness, we examined the ability of a host probiotic and a non-host prebiotic to interfere with O157 STEC colonization and mycotoxin activity in vitro and in vivo [3,4].…”

The present study aims to investigate whether the disease complex for Haemorrhagic Enteritis (HE) in goats during the winter months is the same as described for Jejunal Haemorrhage Syndrome (JHS) in cattle. The further goal is to determine whether prebiotic and probiotic management strategies developed for JHS in cattle alleviate HE in goats. The clinical, necropsy and microbiologic findings were evaluated for goat cases during a natural HE outbreak. Bacterial pathogens were identified using selective media, biochemical tests, latex agglutination tests and DNA microarray. Feed components were evaluated for mycotoxigenic fungi and mycotoxins. Common clinical signs included stary look, grinding of teeth, an odd twisting of the neck when standing, hind-limb paralysis, rumen stasis, no faecal pellets, profuse drooling and a 50% drop in milk production. A prebiotic/probiotic treatment resolved the symptoms in 14 of 28 goats, but new cases continued to develop. The most common morphologic diagnosis at necropsy was severe jejunitis with intraluminal haemorrhage or blood clots confirming HE. The corn silage contained mycotoxigenic fungi and mycotoxins. There were mixtures of Shiga toxin -producing Escherichia coli (STEC) isolated from the jejunum. The probiotic and prebiotic acted as anti-adhesive agents for STEC colonization in vitro. The prebiotic also acted as a mycotoxin binder in vitro. Removing the mouldy corn silage stopped the mycotoxicosis, but did not correct production losses. Adding a prebiotic or probiotic significantly increased milk production and body condition, but also decreased somatic cell counts. Results confirm that the disease complex for HE in dairy goats consuming mouldy feeds includes mycotoxins and STEC infection. The study also supports the use of prebiotics and probiotics to alleviate the morbidity and production losses associated with the mycotoxicosis.

Small ruminants represent an important economic source in small farm systems and agriculture. Feed is the main component of livestock farming, which has gained special attention to improve animal performance. Many studies have been done to improve feed utilisation through addition of feed additives. For a long period, antibiotics have been widely used as growth promoters in livestock diets. Due to their ban in many countries, search for alternative feed additives has been intensified. Probiotics are one of these alternatives recognised to be safe to the animals. Use of probiotics in small ruminant nutrition has been confirmed to improve animal health, productivity and immunity. Probiotics improved growth performance through enhancing of rumen microbial ecosystem, nutrient digestibility and feed conversion rate. Moreover, probiotics have been reported to stabilise rumen pH, increase volatile fatty acids production and to stimulate lactic acid utilising protozoa, resulting in a highly efficient rumen function. Furthermore, use of probiotics has been found to increase milk production and can reduce incidence of neonatal diarrhea and mortality. However, actual mechanisms through which probiotics exert these functions are not known. Since research on application of probiotics in small ruminants is scarce, the present review attempts to discuss the potential roles of this class of feed additives on productive performance and health status of these animals.
