Probiotic bacteria offer a number of potential health benefits when administered in sufficient amounts that in part include reducing the number of harmful organisms in the intestine, producing antimicrobial substances and stimulating the body’s immune response. The human intestinal microbiota is a complex ecosystem with considerable impact on human health and well-being, contributing to maturation of the immune system and providing a direct barrier against pathogen colonization (Doré and Corthier, 2010). Bacteria that initially colonize the large gut of an infant are facultative anaerobes, such as Escherichia coli and Streptococcus sp. Within the gastrointestinal tract (GIT), the microbiota provides various functions, such as digestion of essential nutrients and maturation of intestinal epithelial cells. Lactic acid bacteria (LAB) are Gram-positive, non-spore forming cocci, coccobacilli, or rods, which generally have non-respiratory (fermentative) metabolism and lack true catalase.
Pediococci are also related to the LAB group and are utilized in industrial fermentations of foods and silage (Raccach, 2014).
Another group of LAB promoted as probiotics are enterococci, which reportedly help in the maintenance of normal intestinal microflora and stimulate the immune system (Bhardwaj et al., 2008).
Saccharomyces boulardii is one of the best-studied probiotic species, with a long history of successful use in treatment of multiple gastrointestinal disorders. Another bacterium that has been demonstrated to have a considerable impact on human gastrointestinal microbiota is Faecalibacterium prausnitzii of the Clostridium sp. Other bacteria of the class Clostridia might also find use as potential probiotics, since they are highly abundant in human GIT microbiota and may play an important role in metabolism and immune system function. Although most antibiotics are generally safe, some have the potential to cause life-threatening side effects. Clostridium difficile-associated diarrhea or pseudomembranous colitisis is an inflammation of the intestine walls caused by toxins produced by C. Many probiotic strains have naturally acquired resistance toward one or several antimicrobial agents (Table 2). Courvalin (2006) specified two distinct types of acquired antibiotic resistance in bacteria: (i) initially non-transferred resistance that occurred as a result of one or several mutations in indigenous gene(s), and (ii) transferred resistance, acquired from a different organism by horizontal gene transfer. Multiple studies have already shown that antibiotic resistance can be transferred between different bacterial species that reside in the human GIT. Novel probiotic-based strategies for therapeutic and prophylactic use against multiple GIT diseases are gaining popularity worldwide.
Distribution of specific species of microorganisms is still being studied in healthy humans and compared with those of patients with various gastrointestinal diseases.

However, precisely elucidating the probiotic effect of a specific bacterium has been challenging due to the complexity of the gut’s microbial ecosystem and a lack of definitive means for its characterization. It consists of bacteria, archaea, some protozoa, anaerobic fungi, and different bacteriophages and viruses, and it has been estimated that more than 1000 species of microbes inhabit the human intestine (Tuohy et al., 2012). Live probiotics are commonly available in fermented dairy products and probiotic-fortified foods.
Unlike bifidobacteria, which are active in lower parts of the colon, lactobacilli are prevalent in the upper GIT (Turroni et al., 2011).
They are Gram-positive, non-motile anaerobic saccharolytic bacteria (Gomes and Malcata, 1999). Though intrinsic resistance of probiotic bacteria to certain antibiotics might offer benefits for their use in the prevention and treatment of AAD, the issue of possible transfer of resistance determinants has been raised (Pflughoeft and Versalovic, 2012), particularly for strains that carry plasmids.
For instance, it has been reported that both Lactobacillus lactis and Streptococcus thermophilus are able to transfer erythromycin resistance [erm(B) gene, located on a plasmid] to L.

Their effectiveness has been predicted by numerous animal model studies and proven by extensive research involving humans.
Probiotic strains and methods for their delivery, preselected in vitro, are subsequently tested in animal models. Larger animals like rabbits, dogs, and pigs are generally considered to have more common features with the physiology and microflora of the human GIT (Kararli, 1995). Microbes also have the ability to affect physiologic parameters, providing systemic effects on blood lipids and generally influencing the immune system, as well as inhibiting harmful bacteria (Mikelsaar, 2011). The most common probiotics include representatives of lactobacilli, enterococci, bifidobacteria, and yeasts (Table 1).
These bacteria are added into numerous foods and beverages, ranging from yogurts to breakfast cereals. This group is also a normal member of the human microflora, found in the oral cavity, the small intestine, and the vaginal epithelium, where it is thought to play beneficial roles (Gomes and Malcata, 1999). In the gut environment, bifidobacteria have a commensal relationship with their hosts, and contribute to host nutrition by utilizing complex carbohydrates, which are important sources of carbon and energy, but are not degraded in the stomach or intestine (Biavati, 1994). Moreover, even a short-term course of antibiotics may have a long-term negative impact on the normal human gut microbiota (Jernberg et al., 2010).
CDAD is one of the most common hospital-acquired infections and is a frequent cause of morbidity and mortality among elderly hospitalized patients. The gene responsible for acquisition of antibiotic resistance often resides on a plasmid or transposon, which might be easily transferred (Bennett, 2008). However, rodents are cheap, standardized, and have short life-cycles; thus, their extensive use in large-scale research.
The ingredients in this recipe come together to provide balanced nutrition and a great taste your cat will love! Pathogen inhibition by human intestinal microbiota may provide significant human health benefits through protection against infection as a natural barrier against pathogen exposure in the GIT (Wallace et al., 2011). In addition, bacterial mixtures may be used to achieve the complex beneficial effect of probiotics (Caballero-Franco et al., 2007). There are also tablets, capsules, powders, and sachets containing probiotics in freeze-dried form. Among the beneficial effects, lactobacilli can improve digestion, absorption, and availability of nutrients (Wallace et al., 2011). These substances include plant-derived dietary fiber and diet-related carbohydrates, such as starch, galactan, sucrose, amylopectin, and pullulan (Ventura et al., 2007, 2012). Since butyrate is a primary energy source for intestinal epithelial cells, it is essential for maintenance of epithelial barrier integrity. A similar mechanism of colitis suppression, via IL-10 production by induced macrophages, was observed using strain C.
The most commonly used classes of antibiotics include penicillins, cephalosporins, aminoglycosides, fluoroquinolones, macrolides, and tetracyclines; each of these compounds can cause their own specific side-effects (Cunha, 2001). Microorganisms used in these studies included the genera Lactobacillus, Bifidobacterium, Saccharomyces, Streptococcus, Enterococcus, and Bacillus.
Complications include shock, need for colectomy, toxic megacolon, and in severe cases, perforation of the colon wall.
In fact, transposon-mediated transfer of genetic material between species was recently described as the most frequent mechanism contributing to the spread of antibiotic resistance in bacteria (Wozniak and Waldor, 2010). Another study provided the evidence of in vivo transfer of ampicillin resistance between two strains of E. High quality meat and fish meals, delicious flavor, and our scientifically formulated nutrient-rich recipe make this food a great choice for every cat in your family. Factors such as food contamination by pathogens, as well as the high load of antibiotics in soil and animal feed, can influence the microbial ecology of human GIT (Sapkota et al., 2007). The latter anxiolytic effect has even led to the emergence of the new term, psychobiotic, coined by Dinan et al. Functional foods, defined as food preparations with various health-related properties, often include bacterial strains with declared probiotic properties (Turroni et al., 2011). Furthermore, LAB are capable of hydrolyzing compounds that limit the bioavailability of minerals, like tannin and phytate, due to tannin acylhydrolase and phytase activities (Turpin et al., 2010).

The capacity of bifidobacteria to metabolize non-digestible host dietary carbohydrates (prebiotics) can be used for selective stimulation of certain strains colonizing the intestinal tract. Its influence on metabolic processes in the GIT is not fully investigated; however, it has already been shown that this bacterium may be a potential treatment for type II diabetes. Multiple beneficial effects of butyrate for health also include reduction of cancer progression, protection against pathogens, and stimulation of the immune system (Macfarlane and Macfarlane, 2011).
In fact, most traditionally used antibiotics are able to cause health problems in the GIT, and are commonly related to disturbances in microflora composition caused by survival and spread of resistant strains. According to Friedman (2012), several mechanisms of action of probiotics contribute to the prevention and treatment of diarrhea: enhancing mucosal barrier function by secreting mucins, increasing tight junctions in epithelial cells, providing colonization resistance, producing bacteriocins, increasing production of secretory lgA, producing balanced T-helper cell response, increasing production of IL-10 and transforming growth factor beta.
The most popular materials used for encapsulation of bacteria are alginate, carrageenans and gums, since they are easy to process, resistant to low pH and freezing, and are generally recognized as safe (Gbassi and Vandamme, 2012).
Using molecular genetic tools, it has been shown that antibiotics could induce significant alterations in the dominant colonic microbiota that are not detectable using bacteriological (culture-based) techniques, with effects lasting for up to 2 months (Mangin et al., 1999). In addition, it was shown that some lactobacilli strains could enhance mineral absorption in Caco-2 cells and improve the nutritional status of the host by producing B-group vitamins. Bifidobacteria used as probiotics include strains belonging to species of Bifidobacterium lactis, B. For instance, penicillins, which are known for having the least-frequent and -severe side effects, may cause diarrhea, and nausea, vomiting, and upset stomach. These include osmotic diarrhea, caused by suppression of anaerobic bacteria and a reduction in carbohydrate metabolism, disruption of protective effect of commensal bacteria and reduction of colonic mucosal resistance to pathogenic opportunistic bacteria. Collectively, these factors contribute to the restoration of a normal gastrointestinal balance following damage by antibiotics (Friedman, 2012). However, a large multi-center study is needed to build sufficient evidence in support of probiotic use as a treatment for C.
Several more specific disorders involve disruption of the human microflora ecology: acute gastroenteritis, Clostridium difficile infection (CDI), necrotising enterocolitis in neonates, irritable bowel syndrome and Helicobacter pylori infection (Kotzampassi and Giamarellos-Bourboulis, 2012). Within the following 5 years (up to May 20th 2015), the frequency of publications doubled with 7979 papers being published, including 778 clinical trials.
Though enterococci have probiotic potential, they are considered opportunistic pathogens for humans as they might cause nosocomial infection and are also known to possess resistance to vancomycin (Tambyah et al., 2004). Fluoroquinolones are also considered relatively safe, but may similarly induce nausea, vomiting, diarrhea, and abdominal pain (Bertino and Fish, 2000). Full restoration of the normal gut microbiota may take several weeks or even months (Friedman, 2012; Kaier, 2012).
Extremely high rates of CDAD have been reported in Quebec from 2002 to 2005, totaling 14000 cases (a 4.5-fold increased incidence compared with 1991), with evidence suggesting the emergence of a highly-virulent strain of C.
Probiotics are currently being examined for their potential treatments of these aforementioned disorders.
Due to these controversial properties, the use of enterococci as probiotics remains under debate. Side-effects of macrolides include GIT-associated nausea, vomiting, and diarrhea, whereas adverse effects of the tetracyclines depend on the concentration of the antibiotic in the affected organ. Based on these results it has been suggested that pharmacological manipulation of the gut microbiota in favor of A.
However, though clostridia have potential for use as probiotics, there is still not enough evidence to support their medical efficacy and safety for humans. Their common side-effects include cramps or burning of the stomach, diarrhea, sore mouth, or tongue (Rubinstein, 2001).
Research in this field is ongoing and has already provided evidence for efficacy of probiotic use for prevention of health problems emerging as a result of antibiotic use. Despite an excellent record of safe use, yeasts may still be the cause of localized infections in immunocompromised patients (Thygesen et al., 2012).
Additional beneficial effects of bifidobacterial strains include the prevention or alleviation of infectious diarrhea and the improvement of inflammatory bowel disease symptoms (Sanz, 2007).
