Socialization and Education on The Benefits of Probiotics for Children's Health in Primary School Until Senior High School Students in Tanjung Morawa

Dysbiosis is a condition in which there is an imbalance in the number of microorganisms in the human digestive tract. This condition often occurs in children. An imbalance in the number of microorganisms in the digestive tract in humans (microflora) occurs when bacterial overgrowth. This can cause infection or inflammation localized in the intestine which has the potential to cause various diseases. However, knowledge about probiotics is still not understood by the public. This community service activity aims to provide knowledge about the role of probiotic microorganisms for children's health, especially for elementary-high school children in Tanjung Morawa District. This Community Service activity was carried out by means of a lecture method by disseminating the activity plan to the children of the Yayasan Pauly Mandiri, then a demonstration by conducting counseling and displaying animated videos related to the socialization that was carried out. Community service activities in general received a very good response and high enthusiasm from students, and several teachers who attended as well as the chairman of the Pauly Mandiri Education Foundation in Kec. Tanjung Morawa asked to continue. The results of community service, especially practicing drinking probiotic drinks. The enthusiasm of the participants hopes that this outreach activity can be resumed regarding the manufacture of food or drinks containing probiotics so that children can apply them daily, and consume them to increase body immunity in the midst of a pandemic.

The Effect of Vaccination on Adhesive Features of Microorganisms in Digestive Tract of Japan Quails(Coturnix coturnix japonica)

Investigations were carried out on adhesive features of microorganisms in digestive tract of Japan quails, both unvaccinated ones and those twice treated with Salmonella enteritidis vaccine TALOVAC 109 SE. It is known that the ability of normal intestinal microflora to adhere to wall cells of digestive tract is essential in the formation of colonizational resistance, which is related with the constituent part of immunological status of macroorganism. In this respect our attention was focused on the effect of vaccination upon the ability of representatives of intestinal microbiocenosis in quails to adhere to intestinal wall cells. The results of investigations show that adhesive features of separate microflora strains in the intestine of quails are different independently of whether they were secreted from digestive tract of vaccinated or unvaccinated quails. However, mean values of adherence of intestinal microorganisms of vaccinated and unvaccinated quails indicate that vaccination considerably adds to t...

Fibre-degrading microorganisms in the monogastric digestive tract

The aim of this review is to take stock of our present knowledge of the qualitative and quantitative composition and activity of the microbial population responsible for the degradation of plant cell-wall polysaccharides in monogastric animals and humans. It focuses particularly on animals that may be used as an experimental model for humans. There is also a brief survey of the fibre breakdown in invertebrates. Although the effect of dietary fibres on the human and monogastric animal digestive physiology is generating more and more interest, the knowledge of the microorganisms involved in the fibre breakdown is still limited. Compared with the rumen, only a few studies concerning these micro-organisms in the intestinal tract of non-ruminant animals have been done. Except in humans, studies have essentially been focused on the cellulose-digesting bacteria. The hemicellulolytic and pectinolytic bacteria have received less attention. Bacteria are considered to be the major plant cell wall degrading agents. Little is known of the ability of intestinal protozoa to degrade complex polysaccharides; much work remains to be done on these microorganisms. The data reported in this review show that the numbers of fibre-degrading bacteria in the large intestine of monogastric animals are similar to those found in the rumen and suggest that the cellulolytic bacteria are largely similar in different gut regions of different animal species. Bacteroides succinogenes and Ruminococcus flavefaciens seem largely distributed in the higher animals. Similar strains of Bacteroides, especially B. ruminicola, are hemicellulolytic bacteria found in the digestive tract of numerous mammals, even in the human colon. In contrast, the fibre-degrading microorganisms in the digestive tract of insects or other invertebrates differ from those found in mammals. Flagellate protozoa are the main, if not the only, agents of degradation of plant cell-wall polysaccharides. In many species, the role of bacteria is not clear. This suggests a divergence in the development of microbial digestion of cellulose and hemicellulose in the gastrointestinal tract of invertebrate and higher animals. Much work remains to be done on the taxonomy, ecology, physiology and metabolic activities of the microorganisms capable of degrading plant cell walls. These works should also concern polysaccharide-degrading enzymes of the different microbial species. A better knowledge of the mechanisms involved in polysaccharide breakdown is also required for the optimization of the dietary fibre-digesting microorganisms in animals such as herbivorous birds, reptiles and fishes.
