| association of streptococcus pluranimalium with valvular endocarditis and septicaemia in adult broiler parents. | the genus streptococcus consists of more than 60 species, but only streptococcus equi subspecies zooepidemicus, streptococcus gallolyticus ssp. gallolyticus, streptococcus gallinaceus, streptococcus dysgalactiae, streptococcus mutans and streptococcus suis have been isolated from poultry. during investigations of the aetiology of increased mortality in broiler parent stock at the end of production, pure cultures of streptococcal-like organisms that could not be classified among these six species ... | 2009 | 19322715 |
| characterization of streptococci and enterococci associated with septicaemia in broiler parents with a high prevalence of endocarditis. | increased mortality due to septicaemia, where 29% of the affected birds had developed valvular endocarditis, was observed in a flock of broiler parents affected by myelocytomatosis. bacterial investigations resulted in isolation of streptococci, the classification of which was unknown according to present taxonomy. strains were isolated from the liver, spleen, heart and salpinx in clinical cases of septicaemia from the affected flock of ross broiler parents aged between 26 and 56 weeks. phenotyp ... | 2004 | 15763731 |
| streptococcus gallinaceus sp. nov., from chickens. | three isolates of an unknown gram-positive, catalase-negative, chain-forming, coccus-shaped organism isolated from an outbreak of septicaemia in a flock of adult broiler parents were characterized by phenotypic and molecular taxonomic methods. comparative 16s rrna gene sequencing studies demonstrated that the bacterium represents a new subline within the genus streptococcus, related to, albeit distinct from, streptococcus acidominimus, streptococcus ovis, streptococcus suis and close relatives. ... | 2002 | 12148622 |
| streptococcusmarmotae sp. nov., isolated from the respiratory tract of marmota himalayana. | five strains of a gram-stain-positive, catalase-negative, α-haemolytic, coccus-shaped chain-forming organism were isolated separately from the lower respiratory tracts of five animals of marmota himalayana in the endemic area of plague, the qinghai-tibet plateau, china. based on their morphological characteristics, biochemical features and molecular phylogenetic studies, the strains were placed as representing a new member of the genus streptococcus. comparative 16s rrna gene sequence studies in ... | 2016 | 27473166 |
| molecular and antimicrobial susceptibility profiling of atypical streptococcus species from porcine clinical specimens. | the streptococcus species present broad phenotypic variation, making identification difficult using only traditional microbiological methods. even though streptococcus suis is the most important species for the worldwide swine industry, other streptococcus species appear to be able to cause disease in swine and could represent a higher underestimated risk for porcine health. the aim of this study was to identify streptococcus-like isolates by maldi-tof ms and 16s rrna sequencing and further mole ... | 2016 | 27491454 |
| streptococcus gallinaceus bacteraemia in an abattoir worker presenting with a febrile illness. | streptococcus gallinaceus is a newly described species of viridans streptococci, previously only identified as causing disease in broiler chickens. this organism was recovered in pure culture from blood taken from a new zealand abattoir worker presenting with a febrile illness. this first report of bacteraemia caused by s. gallinaceus in a human may help the understanding of the ecology of this recently described organism. | 2006 | 16772426 |
| reproduction of sepsis and endocarditis by experimental infection of chickens with streptococcus gallinaceus and enterococcus hirae. | this study describes experimental infections in 4-week-old chickens inoculated intravenously with approximately 10(8) colony-forming units streptococcus gallinaceus strain ccug 42692t (c13156) or enterococcus hirae strain dsm 20160 (c17410). birds were necropsied following death and obvious clinical signs of disease or were euthanized weekly after infection for up to 4 weeks. at necropsy, lesions included splenomegaly, hepatomegaly, valvular and/or mural endocarditis. cardiac lesions included fo ... | 2005 | 16191708 |
| characterization of enterococcus hirae outbreaks in broiler flocks demonstrating increased mortality because of septicemia and endocarditis and/or altered production parameters. | in denmark, increased problems associated with streptococci and enterococci have been observed in broilers and broiler parent flocks, resulting in increased mortalities, uneven flocks, and subsequent downgrading and increased condemnations. postmortem lesions associated with recent outbreaks due to enterococcus hirae have been accompanied or dominated by septicemia and endocarditis. as a result of infection at an early age and relatively low mortality rates, outbreaks are not always clearly defi ... | 2005 | 15839407 |
