variation in the limit-of-detection of the prospect campylobacter microplate enzyme immunoassay in stools spiked with emerging campylobacter species.campylobacter enteritis in humans is primarily associated with c. jejuni/coli infection. the impact of other campylobacter spp. is likely to be underestimated due to the bias of culture methods towards campylobacter jejuni/coli diagnosis. stool antigen tests are becoming increasingly popular and appear generally less species-specific. a review of independent studies of the prospect® campylobacter microplate enzyme immunoassay (eia) developed for c. jejuni/coli showed comparable diagnostic result ...201627317896
evidence of campylobacter jejuni reduction in broilers with early synbiotic administration.c. jejuni is considered a food safety concern to both public health authorities and consumers since it is the leading bacterial cause of food-borne gastroenteritis in humans. a high incidence of c. jejuni in broiler flocks is often correlated to pathogen recovery in retail poultry meat, which is the main source of human infection. in this work broiler chickens were fed with a synbiotic product mixed with conventional feed using two different administration strategies. the synbiotic was formulate ...201728390936
microbiota composition and immune responses during campylobacter jejuni infection in conventionally colonized il-10(-/-) mice lacking nucleotide oligomerization domain 2.host immune responses are pivotal for combating enteropathogenic infections. we here assessed the impact of the innate receptor nucleotide oligomerization domain protein 2 (nod2) in murine campylobacter jejuni-infection. conventionally colonized il-10(-/-) mice lacking nod2 and il-10(-/-) controls were perorally challenged with c. jejuni strain 81-176 and displayed comparable pathogenic colonization of intestines until day 14 postinfection (p.i.). whereas overall intestinal microbiota compositio ...201728386467
current and potential treatments for reducing campylobacter colonization in animal hosts and disease in humans.campylobacter jejuni is the leading cause of bacteria-derived gastroenteritis worldwide. in the developed world, campylobacter is usually acquired by consuming under-cooked poultry, while in the developing world it is often obtained through drinking contaminated water. once consumed, the bacteria adhere to the intestinal epithelium or mucus layer, causing toxin-mediated inhibition of fluid reabsorption from the intestine and invasion-induced inflammation and diarrhea. traditionally, severe or pr ...201728386253
interactions of the periplasmic binding protein ceue with fe(iii) n-licam(4-) siderophore analogues of varied linker length.bacteria use siderophores to mediate the transport of essential fe(iii) into the cell. in campylobacter jejuni the periplasmic binding protein ceue, an integral part of the fe(iii) transport system, has adapted to bind tetradentate siderophores using a his and a tyr side chain to complete the fe(iii) coordination. a series of tetradentate siderophore mimics was synthesized in which the length of the linker between the two iron-binding catecholamide units was increased from four carbon atoms (4-l ...201728383577
