| an investigation of bacterial causes of arthritis in slaughter hogs. | joints from 153 arthritic and 80 normal slaughter hogs were examined by culture for presence of bacteria. although none of the normal joints yielded bacteria, 37% of the disease joints were positive for bacterial growth. of 67 bacterial isolates obtained, 45% were erysipelothrix rhusiopathiae. occurrence of other bacteria in order of their frequency was streptococcus suis (16%), actinomyces pyogenes (10%), mycoplasma spp. including 3 m. hyorhinis isolates (7%), staphylococci (7%), streptococcus ... | 1992 | 1554766 |
| [actinomyces pyogenes: conventional and api system bacteriologic study of 103 strains isolated from ruminants]. | one hundred and three strains of actinomyces pyogenes isolated from ruminants were examined for morphological, cultural and biochemical properties by standard tests and by the api 50 ch and api coryne methods. no biotype could be demonstrated, but a few atypical non- or practically non-proteolytic strains were detected which should be differentiated from arcanobacterium haemolyticum. criteria for laboratory identification of a pyogenes were established: gram stain; culture on blood agar; deep ag ... | 1992 | 1610079 |
| human infections with actinomyces pyogenes (corynebacterium pyogenes). | actinomyces pyogenes (corynebacterium pyogenes), a well-known pathogen in many animals, was isolated from 11 danish patients since 1968. bacteriologic characteristics and clinical pictures of the patients are described. ability to hydrolyze gelatine, to produce beta-glucuronidase, to reach with antisera against group-g streptococci, and to produce acid from xylose differentiates a. pyogenes from arcanobacterium haemolyticum, with which it has at times been confused. actinomyces pyogenes is an es ... | 1992 | 1611850 |
| cell surface hydrophobicity of actinomyces pyogenes determined by hexadecane adherence- and salt aggregation studies. | cell surface hydrophobicities of actinomyces pyogenes were determined by measuring the adherence of the bacteria to hexadecane droplets and by salt aggregation tests. among 42 a. pyogenes cultures tested 25 (60%) adhered strongly (adherence greater than or equal to 75%) and 17 (40%) less pronounced (adherence between 25-75%) to the hexadecane droplets. pre-treatment of the bacteria with proteolytic enzymes completely eliminated the adherence properties whereas heat treatment had no effect. the s ... | 1992 | 1621475 |

| further observations on enhancement of the infectivity of fusobacterium necrophorum by other bacteria. | it had already been shown with a single virulent strain (a42) of fusobacterium necrophorum that suspension of the fusobacteria in sub-lethal doses of broth cultures of other bacteria reduced the minimum infective dose (greater than 10(6) organisms) for mice by subcutaneous inoculation, sometimes to less than 10 organisms. the present study extended the known range of bacteria with strong infectivity-enhancing properties to include bacillus cereus, klebsiella oxytoca and staphylococcus aureus; an ... | 1991 | 1902184 |

| effect of damage to the teat end on the experimental induction of mastitis in dry cows with corynebacterium pyogenes. | the teat ends of 12 dry cows were contaminated with corynebacterium pyogenes. to determine whether a pre-existing (an)aerobic bacterial infection of the udder was a predisposing factor for a c pyogenes mastitis they included infected and uninfected quarters. anaerobic bacteria could not be found and mastitis was not induced. when the teats were contaminated with c pyogenes after the teat ends had been injured 30 of the quarters became infected, and anaerobic bacteria were demonstrated in many qu ... | 1991 | 2003353 |
| epizootic of external and internal abscesses in a large goat herd over a 16-year period. | from 1973 through 1988, 518 external and internal abscesses were diagnosed in a large commercial goat herd. of the 518 abscesses, 238 were primary and 280 were secondary abscesses in the same or other anatomic locations. during this period, the herd varied in size from 94 goats in 1973 to 431 goats in 1988. abscesses in the jaw area were detected in 141 goats, 4 of which developed osteomyelitis of the mandible. sternal abscesses were detected in 72 goats, with 2 also having osteomyelitis of the ... | 1991 | 2004986 |
| a sensitive method for isolating fusobacterium necrophorum from faeces. | the isolation of fusobacterium necrophorum present in small numbers in heavily contaminated material such as faeces or soil is hampered by the lack of an efficient selective medium and by the high minimum infective dose of the organism. a sensitive method for the detection and isolation of faecal strains of f. necrophorum type a was based on the subcutaneous injection of faeces, suspended (5% w/v) in broth culture of actinomyces (corynebacterium) pyogenes or staphylococcus aureus to increase fus ... | 1991 | 2019300 |
| aerobic bacteria from nasal discharge of goats suffering from clinical ppr: isolation and identification. | bacteriological isolation of aerobic bacteria from nasal discharge of achondroplastic west african dwarf goats showing clinical signs of peste des petits ruminants (ppr), and the laboratory procedures carried out for the identification of the isolates are described. from a total of forty nasal swabs obtained seventy five isolates were recovered. the percentage frequency of isolation of different organisms in descending order of occurrence is as follows: staphylococcus 44.0%; streptococcus 22.67% ... | 1991 | 2023545 |
| characteristics of actinomyces pyogenes involved in lameness of male turkeys in north-central united states. | a new condition of clinical lameness in 20 male turkey flocks of north-central united states, associated with isolation of gram-positive rod bacteria from lesions of osteomyelitis, is characterized. the characterization confirmed the randomly selected isolates as actinomyces pyogenes based on macroscopic and microscopic observations and 17 biochemical tests. the disease was reproduced within 3 weeks in all male turkeys, following an intravenous challenge at 15 weeks of age. the agar gel precipit ... | 1991 | 2029253 |
| fusobacterium necrophorum hemolysin in bovine hepatic abscess. | an immunofluorescence study was made on bovine hepatic abscess containing fusobacterium necrophorum predominantly. the abscess section stained with anti f. necrophorum hemolysin serum demonstrated fluorescence which formed irregular and granular shapes. actinomyces pyogenes isolates from the abscess were not stained with the serum. these findings suggest that the bacterial hemolysin contributes to the formation of the hepatic abscess during an infection with f. necrophorum. | 1990 | 2082629 |
