| characterization of streptococcus zooepidemicus (lancefield group c) from human and selected animal infections. | we assembled an international collection of strains from sporadic and epidemic human infection with streptococcus zooepidemicus (lancefield group c) for laboratory study. cultural and physiological characteristics of the isolates were determined, including biotyping with the api 20 strep test kit and susceptibility testing with penicillin, erythromycin and tetracycline. the strains were examined for bacteriocin production and sensitivity and typed with a specially developed group-c streptococcal ... | 1987 | 3556444 |
| hyaluronic acid--a versatile biopolymer. | since its discovery from bovine synovial fluid, hyaluronic acid has found application in several diverse areas. it is now extensively used in ophthalmic surgery, in the treatment of lameness in racehorses and as an ingredient in cosmetics. it can also be used in drug delivery, orthopedics, cardiovascular aids and in wound healing. even so, its potential as a therapeutic agent is yet to be fulfilled. new improved products, formed by crosslinking hyaluronic acid with itself or other chemicals, are ... | 1990 | 1366369 |
| dna fingerprinting of streptococcus zooepidemicus (lancefield group c) as an aid to epidemiological study. | a collection of streptococcus zooepidemicus strains from human and animal infections was examined for dna banding patterns after nuclease digestion and agarose gel electrophoresis. the large variety of dna fingerprints found revealed the complexity of the species but showed that isolates from clusters of outbreaks had identical prints. the results confirmed the specificity of bacteriocin and bacteriophage typing of s. zooepidemicus; the technique also gave useful profiles on untypable strains. s ... | 1987 | 3572034 |
| communicable disease associated with milk and dairy products in england and wales: 1983-1984. | during the period 1983-1984 32 outbreaks of disease (ii in 1983 and 21 in 1984) associated with consumption of milk and dairy products and affecting at least 714 people were reported from england and wales. twenty-seven of the outbreaks were attributed to raw milk, two to contaminated pasteurised milk and one each to cheese, cream and ice-cream. twenty-two were due to salmonellas, seven to campylobacters and one each to staphylococcus aureus, yersinia enterocolitica and streptococcus zooepidemic ... | 1986 | 3722841 |
| pasteurisation and the control of milkborne infection in britain. | infections carried in milk, particularly salmonellosis and campylobacter enteritis, have continued to feature in great britain in recent years. less commonly reported infections included an outbreak in 1984 in england due to streptococcus zooepidemicus, in which 12 people, eight of whom died, were admitted to hospital. the implementation of legislation in 1983 requiring heat treatment of cows' milk for sale to the public reduced the incidence of milkborne infection in scotland compared with prev ... | 1985 | 3926238 |
| binding of human fibronectin to group a, c, and g streptococci. | a total of 387 bacterial strains belonging to 35 species were tested in direct binding experiments for the uptake of purified radiolabeled human fibronectin. positive binding was found in group a, c, and g streptococci and in staphylococcus aureus. the group c streptococcal species streptococcus equisimilis, streptococcus zooepidemicus, streptococcus equi, and streptococcus dysgalactiae were uniformly reactive with fibronectin. beta-hemolytic bovine group g streptococci showed the same degree of ... | 1983 | 6299959 |
| [bacteriological and morphological findings in aborted cattle fetuses]. | bacteriologic investigations were carried out on a total of 142 fetuses aborted by cows. c. pyogenes, v. fetus, streptococcus pyogenes animalis (sofia), m. bovigenitalium, a. laidlawii, e. coli, and b. subtilis were isolated from 34 fetuses (24 per cent). besides, single of these species were found in 80 per cent of the positive cases, and a mixed infection--in 20 per cent. the morphologic changes in all 34 fetuses that were positive were seen chiefly in the lungs and liver. such lesions, howeve ... | 1982 | 6820745 |
| lack of virus-specific bacterial adherence to bovine embryonic lung cells infected with bovine parainfluenza virus type 3. | infection of bovine embryonic lung cells with bovine parainfluenza virus type 3 did not induce in vitro, virus-specific, hemadsorption-related adherence of corynebacterium pyogenes, haemophilus somnus, staphylococcus aureus, streptococcus zooepidemicus, pasteurella haemolytica, listeria monocytogenes, escherichia coli, pasteurella multocida, brucella sp., or salmonella typhimurium. | 1983 | 6302133 |
| fractionation of rat igg subclasses and screening for igg fc-binding to bacteria. | the four igg subclasses of the rat, iggl, igg2a, igg2b and igg2c, were purified from normal serum by a combination of protein a-affinity chromatography and deae-cellulose chromatography. purified, radiolabelled preparations of igg were tested for binding to gram-positive bacteria representing five different fc-receptor (fcr) types. distinct rat subclass-specific fc-binding was noted to bacterial species belonging to different fc-receptor types. staphylococcus aureus (fcr i) strains bind iggl and ... | 1982 | 7078553 |
| isolation and characterization of a novel collagen-binding protein from streptococcus pyogenes strain 6414. | in this report we have analyzed the binding of collagen to streptococcus pyogenes strain 6414. this binding was rapid, specific, and involved a limited number of receptor molecules (11,600 copies per cell). when the proteins in a streptococcal lysate were blotted onto a nitrocellulose filter and probed with 125i-labeled collagen, a prominent collagen-binding protein of 57 kda was identified as well as minor 130-150-kda components. the major 57-kda protein was isolated by affinity chromatography ... | 1995 | 7814395 |
| investigation of milk-borne streptococcus zooepidemicus infection associated with glomerulonephritis in australia. | an outbreak of infection due to streptococcus zooepidermicus is reported. the index case was a patient who suffered an episode of septicaemia complicated by glomerulonephritis. two other persons in his family were found to be asymptomatic throat carriers. the source of the outbreak was unpasteurised milk from a house cow on the farm where the family lived. molecular studies confirmed that the strains isolated from the index case, the other family members and the cow's milk were identical. althou ... | 1993 | 8308327 |
| evaluation of hyaluronan from different sources: streptococcus zooepidemicus, rooster comb, bovine vitreous, and human umbilical cord. | sodium hyaluronate (ha) is widely distributed in extracellular matrixes and can play a role in orchestrating cell function. consequently, many investigators have looked at the effect of exogenous ha on cell behavior in vitro. ha can be isolated from several sources (e.g., bacterial, rooster comb, umbilical cord) and therefore can possess diverse impurities. this current study compares the measured impurities and the differences in biological activity between ha preparations from these sources. i ... | 2004 | 15530025 |
| detection of equine herpesvirus type 1 using a real-time polymerase chain reaction. | equid herpesvirus 1 (ehv1) is a major disease of equids worldwide causing considerable losses to the horse industry. a variety of techniques, including pcr have been used to diagnose ehv1. some of these pcrs were used in combination with other techniques such as restriction enzyme analysis (rea) or hybridisation, making them cumbersome for routine diagnostic testing and increasing the chances of cross-contamination. furthermore, they involve the use of suspected carcinogens such as ethidium brom ... | 2006 | 16137772 |
| evidence for niche adaptation in the genome of the bovine pathogen streptococcus uberis. | streptococcus uberis, a gram positive bacterial pathogen responsible for a significant proportion of bovine mastitis in commercial dairy herds, colonises multiple body sites of the cow including the gut, genital tract and mammary gland. comparative analysis of the complete genome sequence of s. uberis strain 0140j was undertaken to help elucidate the biology of this effective bovine pathogen. | 2009 | 19175920 |
| streptococcus equi subsp. zooepidemicus meningitis. | a 72-year-old woman was hospitalized for streptococcus equi subsp. zooepidemicus meningitis. the same organism was cultured from her two horses. she denied contact with horses, but had a practice of consuming unpasteurized milk from a cow. the cow was in the same stable as the horses, and the ill woman's son milked the cow. | 2008 | 18287302 |
| competitive protein adsorption on polysaccharide and hyaluronate modified surfaces. | adsorption of bovine serum albumin (bsa) and fibrinogen (fg) was measured on six distinct bare and dextran- and hyaluronate-modified silicon surfaces created using two dextran grafting densities and three hyaluronic acid (ha) sodium salts derived from human umbilical cord, rooster comb and streptococcus zooepidemicus. film thickness and surface morphology depended on the ha molecular weight and concentration. bsa coverage was enhanced on surfaces in competitive adsorption of bsa:fg mixtures. dex ... | 2011 | 21623481 |
