| induction of spotty liver disease in layer hens by infection with campylobacter hepaticus. | spotty liver disease (sld) in chickens can present with variable impacts on mortality and production, ranging from sporadic mortalities of individual birds and no notable impact on production to severe reduction in egg output and increased mortality in layer flocks of greater than 1% per day. it was first described over 60 years ago and there have been sporadic reports of the disease throughout the intervening decades, particularly in the us, uk and germany. recently it has become of increasing ... | 2017 | 28110791 |
| campylobacter hepaticus sp. nov., isolated from chickens with spotty liver disease. | ten strains of an unknown campylobacter species were isolated from the livers of chickens with spotty liver disease in australia. the strains were gram-stain-negative, microaerobic, catalase- and oxidase-positive and urease-negative. unlike most other species of the genus campylobacter, most of the tested strains of this novel species hydrolysed hippurate and half of them could not reduce nitrate. all strains showed resistance, or intermediate resistance, to nalidixic acid and most of them were ... | 2016 | 27498969 |
| genome reduction for niche association in campylobacter hepaticus, a cause of spotty liver disease in poultry. | the term "spotty liver disease" (sld) has been used since the late 1990s for a condition seen in the uk and australia that primarily affects free range laying hens around peak lay, causing acute mortality and a fall in egg production. a novel thermophilic sld-associated campylobacter was reported in the united kingdom (uk) in 2015. subsequently, similar isolates occurring in australia were formally described as a new species, campylobacter hepaticus. we describe the comparative genomics of 10 c. ... | 2017 | 28848714 |
| rapid and specific methods to differentiate foodborne pathogens, campylobacter jejuni, campylobacter coli, and the new species causing spotty liver disease in chickens, campylobacter hepaticus. | campylobacter jejuni and campylobacter coli play a major role in bacteria-related foodborne illness in humans. recently, a newly identified species, campylobacter hepaticus, was shown to be the causative agent of spotty liver disease in chickens. the pathogenic potential of c. hepaticus in humans is unknown. this new species contains genes usually used to detect c. jejuni and c. coli in dna-based detection methods, such as the hippuricase (hipo) gene and the glya (serine hydroxymethyltransferase ... | 2018 | 29356597 |
| campylobacter hepaticus, the cause of spotty liver disease in chickens, is present throughout the small intestine and caeca of infected birds. | spotty liver disease (sld) causes significant egg production losses and mortality in chickens and is therefore a disease of concern for some sectors of the poultry industry. although the first reports of the disease came from the united states in the 1950s it is only recently that the organism that causes the disease was identified, isolated, and characterised as a new bacterial species, campylobacter hepaticus. the first isolations of c. hepaticus were from the livers and bile of sld affected b ... | 2017 | 28757028 |
