an autopsy case of erysipelothrix rhusiopathiae endocarditis.a 58-year-old man was admitted to our hospital with fever. the vegetation was confirmed by echocardiography on the tricuspid valve and erysipelothrix rhusiopathiae was isolated by blood culture. the patient died due to heart failure, and tricuspid valve vegetation was confirmed on autopsy and the sample of gram's staining showed gram-positive microcolonies. although about 60 cases of e. rhusiopathiae endocarditis have been reported, japanese cases are extremely rare.200818670152
comparison of the pathogenicity for chickens of erysipelothrix rhusiopathiae and erysipelothrix tonsillarum.twenty-two strains of erysipelothrix rhusiopathiae, 14 strains of erysipelothrix tonsillarum, and four other strains representing two serovars were examined for virulence in 30- to 40-day-old specific pathogen-free chickens. some of the chickens that were given strains of serovars la, 2, 5, 6, 8, 9, 15 or 21 of e. rhusiopathiae showed signs of disease, lesions, bacteraemia or recovery of the bacterium. in contrast, there were no clinical signs, pathological lesions or bacterial isolations in chi ...199418671089
erysipelas in poultry. prevalence of serotypes and epidemiological investigations.eight different serotypes of erysipelothrix rhusiopathiae were isolated from 39 outbreaks of erysipelas in poultry, serotypes 1, 5, 6 and 9 being most prevalent. more than one serotype was demonstrated in five outbreaks. only white leghorns were affected as far as erysipelas in chickens is concerned, and 94% of the flocks were kept on sloping wire floors of the pennsylvania system. no relationship between serotype, host predilection and virulence was observed, nor was there a seasonal distributi ...198018770273
erysipelas in egg-laying chickens: clinical, pathological and bacteriological investigations.clinical observations over several months of 2 flocks of white leghorn chickens producing eggs for consumption and infected with erysipelas revealed a mortality of 13% and 33%. egg production was not affected. histopathological examinations showed non-specific septicemic changes of the liver, kidney and spleen. lesions in endocardium, joints and skin, which are seen in turkeys and pigs, were not observed. from 50 birds examined from each flock, erysipelothrix rhusiopathiae was isolated from 78% ...197518777293
erysipelas in egg-laying chickens serological investigation.examination was made of 81 strains of erysipelothrix rhusiopathiae isolated from chickens which had died of septicaemic erysipelas. the strains originated from two flocks producing eggs for consumption, 34 from flock a and 47 from flock b. typing was performed by the tube precipitation and the agar gel precipitation test. all strains from flock b belonged to type 1b, while 27 strains from flock a belonged to type 4. the seven strains which could not be classified require further examination incl ...197518777308
effect of blood sample handling post-collection on erysipelothrix rhusiopathiae antibody titres.a study was conducted to determine the effect of blood sample mishandling on the performance of an enzyme-linked immunosorbent assay for the detection of antibodies against erysipelothrix rhusiopathiae. eleven sample maltreatments (storage at -10 degrees c, storage at 4 degrees c, heat treatment of clotted blood, haemolysis, repetitive freeze-thaw cycling, and substitution of plasma in place of serum) were simulated in a laboratory environment and then run concurrently against a gold standard sa ...200918783968
a case of erysipelothrix rhusiopathiae causing bilateral endogenous endophthalmitis.this report describes a case of bilateral endogenous endophthalmitis caused by erysipelothrix rhusiopathiae, an occupational zoonotic pathogen, which was successfully treated with intravenous penicillin g followed by oral linezolid. this is believed to be the first report of e rhusiopathiae causing endogenous endophthalmitis.200818818268
health risks for marine mammal workers.marine mammals can be infected with zoonotic pathogens and show clinical signs of disease, or be asymptomatic carriers of such disease agents. while isolated cases of human disease from contact with marine mammals have been reported, no evaluation of the risks associated with marine mammal work has been attempted. therefore, we designed a survey to estimate the risk of work-related injuries and illnesses in marine mammal workers and volunteers. the 17-question survey asked respondents to describ ...200818828566
