background: integrons are the major reasons of multidrug resistance (mdr) among enteropathogenic bacteria. occurrence of horizontal gene transfer between integron-carrying microorganisms and other enteric bacteria may increase the rate of emergence of integron-associated antibiotic resistance. objectives: the objective of this study was to investigate class 1 integrons among members of enteropa...

in this study, symbiotic yog-ice (rozen yogurt) was produced that was inoculated with different levels of inulin(0,2.5 amd 5%)as prebiotic compound and lactobacillus casei as probiotic bacteria in two types; free and encapsulated with sodium algint-whey protein concentration for low fat yog-ice cream.the survivability of this probiotic bacteria was evaluated under simulated gastro-intestinal co...

Chitosan was used for nanoencapsulation of Lactobacillus acidophilus as probiotic bacteria. In vitro experiments were done with the objective of investigating the survival of the bacteria cells in gastro-intestinal conditions. The results demonstrated that the size of chitosan nanoparticles noticeably increases by increasing chitosan concentration from 0.05 to 0.5 g/mL. Encapsulation of the cel...

the formation and regulation of vertebrate endogenous intestinal microbiota has been widely studied as the microbiota plays a crucial role in the host nutrition, development, and health. despite the importance of microbiota for host health, it is still unclear whether the endogenous intestinal microorganisms are genetically distinct or whether they are genetically related with each other in dif...

clostridium perfringens (c. perfringens) is related to gram-positive and anaerobic bacteria. this rod-shaped bacterium produces spores and can cause a wide spectrum of diseases in humans and animals. every of five different bacterium types can lead to different diseases. most of distinct bacterial recognition methods are not completely effective and practical in all condition. the objective of ...

microencapsulation as one of the most modern methods has remarkable effects on probiotic survival. in this study lactobacillus casei (atcc 39392) and bifidobacterium bifidum (atcc 29521) were encapsulated using calcium alginate-gelatinized starch, chitosan coating and inulin via emulsion technique, and were incubated in simulated gastric juice (along with pepsin, ph=1.5) and simulated intestina...

introduction: bacterial translocation is defined as the passage of bacteria from intestinal tract to the extraintestinal organs such as the peritoneum and blood circulation. the aim of this study is to examine bacterial translocation (regarding type of bacteria and effect of time of obstruction on bacterial translocation) from intestinal lumen to the peritoneum and viscera in acute, simple mech...
