SUMMARYYoung Rhesus monkeys (Macac mulatta) were infected orally with a human strain of Campylobacter jejuni. The disease induced was mild, with inappetence and diarrhoea of short duration, but prolonged intermittent excretion of the bacteria in the faeces occurred. Bacteraemia was generally present for 2-3 days and later the organisms localized in the liver and gall bladder. Recovered animals, when challenged with the same strain, showed no clinical symptoms, no bacteraemia, and excreted the organisms in the faeces for only 3 days.
SUMMARYFive quarters of the udders of two lactating cows were infected by intramammary inoculation with Campylobacter coli/jejuni in doses ranging from 2-6 colony-forming units (c.f.u.) to 3*8 x 109 c.f.u. The infected quarters developed clinical mastitis and the campylobacters were reisolated in large numbers from the milk. The milk from the uninfected quarters, and blood and faeces remained free of the organisms. The campylobacters could only be isolated by incubation of culture plates in a microaerobic atmosphere. The results showed that C. coli/ jejuni can cause mastitis in the cow and that the bovine udder is a potential source of C. coli/jejuni in raw milk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
