Chronic enterocolitis is the leading cause of morbidity in colonies of captive rhesus macaques (Macaca mulatta). This study's aim was to identify the common enteric pathogens frequently associated with chronic enterocolitis in normal, immunocompetent rhesus monkeys and to elucidate the influence of this clinical syndrome on the host immune system. We analyzed the fecal specimens from 100 rhesus...
Bacteria have developed several defense mechanisms against bacteriophages over evolutionary time, but the concept of prokaryotic RNA interference mediated defense mechanism against phages and other invading genetic elements has emerged only recently. Clustered regularly interspaced short palindromic repeats (CRISPR) together with closely associated genes (cas genes) constitute the CASS system t...
In this study, antimicrobial and synergistic activity of ingredients of betel quid i.e. kattha, lime, betel leaf, betel nut, cardamom, clove and fennel seeds was tested against microbial population of oral cavity and four enteric pathogens namely Staphylococcus aureus, Salmonella typhi, Escherichia coli and Shigell flexneri. For this purpose two methods were used. Pour plate method was used for...
Enteric pathogens from biofertilizer can accumulate in the soil, subsequently contaminating water and crops. We evaluated the survival, percolation and leaching of model enteric pathogens in clay and sandy soils after biofertilization with swine digestate: PhiX-174, mengovirus (vMC0), Salmonella enterica Typhimurium and Escherichia coli O157:H7 were used as biomarkers. The survival of vMC0 and ...
One of the clearest functions of the gut microbiota in humans is resistance to colonization by enteric bacterial pathogens. Reconstitution of the microbiota offers an exciting therapeutic approach, but great challenges must be overcome.
Diarrhea is a major clinical problem affecting foals up to 3 months of age. The aim of this study was to identify enteric microorganisms involved in monoinfections and coinfections and the associated virulence factors in healthy and diarrheic foals. Diarrheic (D) (n = 56) and nondiarrheic (ND) foals (n = 60) up to three months of age were studied. Fecal samples were analyzed for identification ...
INTRODUCTION The role of Origanum ehrenberjii against bacteria that cause enteric diseases is well known. Salmonella and Enterococcus cause high rates of enteric infections around the world. The aim of this study was to extract essential oils from cultivated and naturally growing O. ehrenberjii, compare the chemical profiles of the extracts and estimate their antimicrobial efficacy against ente...
